The global market of flexible packaging.

 

The flexible (converted) plastic packaging market is recorded growth over the next decade as emerging market consumer's increase their consumption of a variety of packaging consumer goods and new opportunities for the packaging industry emerge through premiumisation of packaging and increasing healthcare needs in developed markets. Also as consumer trends and demographics change globally to require more convenience goods and smaller portioned goods, the demand for flexible (converted) plastic packaging will increase. The global flexible packaging market is largely driven by the growth in its end-use industries. The penchant for consumption of packaged products such as packaged food & beverage, personal care products, and pharmaceuticals is resulting in its growth. Consumers' push for convenient packaging would result in the growth of the PP/PE pouches, polythene and polypropylene sachets, PE and PP bags, and other types of flexible packaging manufactured by PP/PE pouches, sachets and PE,PP bags manufacturers and other factories. These novel pack types with varying sizes and innovative closures are expected to gain momentum in the near future. This market consists of various stake holders, such as packaging manufacturers, traders, distributors, and raw material suppliers of food, beverage, personal care products, pharmaceuticals, and flexible packaging products.  The global flexible market has made little strides in terms of value and regaining the volume lost during the economic slowdown. However, the market has grown considerably in the last few years and is expected to grow at a faster pace in the near future. Factors such as growing consumer preferences towards consuming convenient packaged food & beverages, personal care products, and pharmaceutical is helping this global packaging industry to grow. Increasing innovations in the packaging industry help to drive down the cost and new package types act as an important driver for the flexible packaging market. The important materials used in flexible packaging market are polyethylene, polypropylene, BOPET, EVOH, polyamide, paper, aluminum, cellulosic, and PVC.  This raw material is converted into films that are further converted into pouch, sachet, and bags in which the products are packaged. * Flexible packaging has also benefited from a wider range of new products being developed by brand owners in an increasingly competitive consumer marketplace. Barrier flexible packaging will continue to grow in importance as the major retail chains demand greater product protection and longer shelf life. Flexible packaging has reached market maturity in the developed nations of North America and western Europe and future growth will be modest. However, Smithers Pira expects flexible packaging to see stronger growth in developing countries. Demand in North America's converted flexible packaging market has been underpinned by recovering economies and flexible packaging formats being used as alternatives to traditional rigid packaging. Asia-Pacific has the highest market share and is estimated to grow with a CAGR of 7.1% during the period under review. Europe is growing with a CAGR of 3.9%, and is driven mainly by the East European markets. ROW is also expected to experience growth in flexible packaging market in the future. The CAGR for ROW is 6.0% from 2013 to 2018. The four most potential nations for flexible packaging market are India, China, Russia, and Brazil which are poised to exhibit the fastest growing trend. Many people play up the recyclability aspect of sustainability as it relates to packaging at the exclusion of the front end of a package’s life cycle. The carbon footprint of various packaging types has to consider many factors. For example, pouches offer tremendous energy savings both in their production and transport. Comparing rigid containers versus pouches, you can ship one truckload of flat pouches that have the equivalent product-holding capacity of upwards of 15 to 25 truckloads of empty rigid containers. Packagers can also save hundreds of thousands of dollars in packaging material costs and secondary packaging operations systems due to simplifications of packaging systems, such as the elimination of labeling, capping, etc. In the flexible packaging market, pharmaceutical packaging is the fastest growing market with a CAGR of 7.1% during the forecast period. Due to the increased awareness for public health, increasing product processing units, convenience packaging, and rising consumption of generic drugs, the pharmaceutical packaging industry is exhibiting strong gains. Following it, the food packaging is estimated to be the second fastest growing market in 2013, due to the rise in consumption of packaged food. Growing health concerns and knowledge about the nutrition value is driving the market for packed products to preserve the end-products. * Asia is the largest regional market with 29.1% of global market volume in 2011, followed by western Europe and North America. Asia is also the fastest-growing market for consumer flexible packaging, with a forecast CAGR for 2011-16 of 7.9%. The region is forecast to represent 55.0% of total world flexible packaging consumption growth during the period 2011-16. India and China are the fastest-growing national markets for consumer flexible packaging according to Smithers Pira, together accounting for 44.0% of world flexible packaging consumption growth during the forecast period.

The grain logistics in China.

The grain logistics in China.

Nowadays Chinese grain logistics resources are disperse, and grain logistic enterprises are of big quantities but small-scale, difficult to form the scale economy. As the grain logistics facilities are often very large investment projects, common enterprise is difficult to bear it; on the other hand, effective logistics facilities are not immediate profit, there is a strong external effects between individual logistics project - complementary, highly dependent between each other. ROI will be the highest only in co-ordination planning, so most business investment attitude is not positive overall progress of the case.

At the moment, the construction of China 's major grain logistics infrastructure projects rely on enterprises to invest in rather than government investment, resulting in China's grain logistics infrastructure in the overall backwardness, low level of mechanization and automation facilities, the loss of food alarming rate. Because of the backward way of loading/unloading and transportation, loss of about 8 million tons of grain annually in China.With China's accession to WTO, food markets gradually with international standards on food production, packaging, marketing and other issues need to have the appropriate laws, regulations and industry standards to regulate the operation of the market . For example, currently PP woven bags(or known as PP bags) commonly used in the food market, there is not a uniform standards for food packaging, packaging legislation lags far behind more developed countries in the packaging industry.

As a modern grain logistics technology and advanced management mode of operation throughout the entire process of grain circulation, the government and enterprises should improve the understanding of modern grain logistics, learn and master advanced management techniques and modes of operation, according to their actual needs of the market and actively promote the use of modern grain logistics. At present, China Food Industry Association, Transport Association and other industry management system is being formed, and gradually standardized. These associations play a pivotal role in strengthening market supervision, standardize the operation of the market. On the issue of food logistics, as it involves a number of areas, involving different departments, industry associations should strengthen cooperation and overall study of modern grain logistics mode. To reduce logistics costs, save resources and reduce food losses and increase efficiency,the grain circulation "scattered" ( bulk loading, bulk unloading, bulk transportation and bulk storage) is the development direction.

1, The government should increase the strength of grain logistics technology and capital investment, through independent research and development and the introduction of foreign, accelerate the development of key grain logistics facilities and equipment, the development of common bulk grain trains, bulk grain containers and bulk grain cars as soon as possible, to promote the bulk grain transport technology and equipment, improve the logistics of food technology and equipment, to achieve food storage facilities, vehicles, machinery, information coding standardization and quality testing of loading and unloading. 2,Government should support large-scale grain logistics enterprises, give them the preferential policies on taxation. 3, The positive development of third-party food logistics enterprises, encourage investment in social capital and absorb grain logistics.

Printing plates and flexible printing.

Printing processes such as offset lithography use printing plates to transfer an image to paper or other substrates.The plates may be made of metal, plastic, rubber, paper, and other materials. The image is put on the printing plates using photomechanical, photochemical, or laser engraving processes. The image may be positive or negative. Typically, printing plates are attached to the plate cylinder in the press. Ink is applied to the plate's image area and transferred directly to the paper or to an intermediary cylinder (blanket) and then to the paper. In screen printing, the screen is the equivalent of the printing plate. It can be created manually or photochemically and is usually a porous fabric or stainless steel mesh stretched over a frame.

Flexible printing is including flexible packaging film and label printing. Types include two sides, the image printed on your PP woven bags(also named as PP bags) and PE film etc., will always appear in the same position from one item to the next. The number of printing plates needed for a job where printing is done on both sides of the sheet of paper is determined not only by the number of colors of ink but also by how the sheets are imposed and fed into the printing press. 

Ink is applied to a plastic surface through flexible rubber or polymer plates. This printing uses quick-to-dry inks. The inks dry through evaporation.Flexible printing does work by imprinting lettering and imagery on the surface of a stand up pouch. The letters and images are engraved onto flexible rubber or polymer plates. They are engraved in the form of tiny indentations. Ink is rolled onto the plates which in turn are joined with letterpress cylinders. The small indentations in the plates hold the ink. The ink is transferred to plastic or other printing surface when it comes into contact with the inked plates.A big advantage of using flexographic printing is the time it takes to make custom printed flexible pouches. It is quicker to make custom stand up bags with flexography than with rotogravure printing. Another big advantage of the technique is that it has been tried and tested. It has been around since the late 19th century. It has evolved a lot in during the 20th century. Thirteen years into the 21st century, and it remains a popular printing technique.

What are the protective performances of food packaging?

 

Nutrition and safety (hygiene) are natural attributes of food, which embodies the practical performance of the food, but the food and very perishable, so the basic characteristics of food packaging is the need to ensure food and nutrition in the process of storage and distribution, the quality of health and quality of flavor. Different food deterioration due to different reasons damage and performance requirements for protective packaging is not the same, but the basic requirements generally include the following: a)Rigid packaging requirements has a certain toughness and strength, in order to ensure safe food storage. b)Adaptability, means shall be suitable for the needs of various techniques for food packaging, such as adaptation frozen, pasteurized, special needs, chemical corrosion, radiation sterilization and salts, sugars and other pickled. c)Health and safety requirements of packaging containers pollution, disease-causing bacteria do not exceed the health sector. Packaging materials, non-toxic , does not react chemically with the food, the material should be non-toxic after aging, toxic decoration printing inks; material and the total content of the resolved food substances like solvents harmful heavy metals in particular not more than national regulations. d)Barrier packaging including moisture, gas and aroma barrier properties. The packaging material should prevent the penetration of water vapor, gas or vapor barrier has full or minimal permeability to prevent oxygen from entering the packaging to prevent smell emanating from packaging, food packaging to prevent water evaporation and water vapor into the outside . From the viewpoint of food packaging, aroma retention is important, it is need to contain food hydrocarbons, aliphatic esters and other substances take different techniques. e)Shading is mainly for greasy food. For example, in order to prevent lipid oxidation and rancidity caused by ultraviolet radiation, generally require the use of aluminum foil, metallized film and paper packaging. 5)Packaging for powdered food, for example, many powder food products are packed in PE bags,PP woven bags or PP bags,the product powder and the generated electrostatic adsorption of the bag, the impact strength of heat-sealing of food packaging and sealing effect. In general, anti-static packaging of external law and internal anti-static method. External antistatic method is considered to prevent generation of static electricity can be charged using the characteristics of the material, so that the opposite side of the charged, so that mutual cancel or reduce the friction between the film and the pressure roller, and an increase in environmental humidity. Internal antistatic electrostatic method is a rapid production process leak, the main methods to improve the conductivity of the film material and increasing the humidity of the surface, such as adding an antistatic additive or coating during film forming. The additive is a surfactant, the conductivity mechanism is a hydrophilic group by means of adsorption of molecules of water in the air, the water forms a film-like conductive material in the plastic.

The chemical features knowledge of polypropylene.

 

Polypropylene is a versatile thermoplastic material, compatible with many processing techniquesand used in many different commercial applications. It is one of the fastest growing classesof commodity thermoplastics, with a market share growth of 6–7%/year, and the volume of polypro-pylene produced is exceeded only by polyethylene and polyvinyl chloride. Polypropylene is available in a wide variety of melt flow rates, ranging from 0.3 to over 1000 g/10min., and it is easily recycled. It can be processed by virtually all methods, including injection mold-ing, blow molding, extrusion, blown and cast film, and thermoforming. Many available grades with different properties make polypropylene useful in applications such as fibers, films, filaments, and injection molded parts for automobiles, rigid packaging, appliances, medi-cal equipment, food packaging, and consumer products. It is being substituted for glass, metal, and engineering plastics such as ABS, polycarbonate, polystyrene, and nylon in kitchen appliances and large appliances such as ovens, dishwashers, refrig-erators, and washing machines, and high flow grades are used in molding large housewares. Super-soft grades are replacing polyvinyl chloride in medical bags and tubing and in hospital gowns. Because of its structure, isotactic polypropylene has the highest crystallinity, resulting in good mechanical properties such as stiffness and tensile strength. Syndiotactic polypropylene is less stiff than isotactic but has better impact strength and clarity. Due to its irregular structure, the atactic form has low crystallinity, resulting in a sticky, amorphous material used mainly for adhesives and roofing tars. Increasing the amount of atactic polypropylene in a predominantly isotactic formulation increases the room temperature impact resistance and stretchability but decreases the stiffness, haze, and color quality. The amount of atactic polypropylene in a polypropylene formulation is indicated by the level of room temperature xylene solubles; levels range from about 1–20%. Polypropylenes generally have higher tensile, flexural, and compressive strength,because of these advantages,normally we use it as the material of PP woven bags as the packaging, as well as the bulk bags and other packaging bags,etc. Polypropylene is a versatile thermoplastic material, compatible with many processing techniquesand used in many different commercial applications.

Sheet: PP/PE blends of raw materials, mainly for stationery and plastic products , such as file folders, designer folders, albums, disposable cups and so on. In addition, PP can also be used out of bars, plates and other products. e) Hollow products PP product has transparency and good mechanical properties, mainly for single bottles of detergents, cosmetics and pharmaceutical packaging, composite materials with barrier composite bottle can be used for as the packaging for food, liquid fuels, chemical,and so on.

Basic characteritics of master batch.

Basic characteritics of master batch.

Master batch is excessive chemical additives, used in polypropylene yarn extrusion processing,the carrier resin and dispersant components,is the extraordinary amount of master batch pigment (dye) are uniformly attached to the resin contained in the obtained aggregate. 

The main characteristics of master batch:

a) Pigment

Generally divided organic pigments such as phthalocyanine green, etc.; inorganic pigments such as red iron oxide, titanium dioxide, etc.; dyes such as restoring pink, Disperse Orange and so on. Polyolefins, PVC master batch is used in pigments, dyes is not available for the general said polyolefin coloring, otherwise it will cause severe migration.

b) As dispersing agent

Mainly on the pigment surface wetting, is conducive to further pigment dispersion and stability in the resin, and good compatibility with the resin must not affect the coloring product quality. Polyolefin master batch dispersants generally use low molecular weight polyethylene wax or zinc stearate, etc. Plastic master batch using a polar dispersant generally low molecular weight polyethylene wax, stearic acid, magnesium stearate and calcium.

c) The carrier resin

Make the pigment evenly distributed granular master batch. The carrier is selected to consider the compatibility of the resin to be colored, but also consider the master batch should have good dispersibility, so the carrier mobility should be longer than the colored resin, while being colored does not affect the product quality. If a larger selection of similar melt index polymer, the melt index of the master batch was significantly higher in the polymer, in order to ensure that the final product of the same color. PE, PP master batch select LDPE (low density polyethylene) resin as the carrier, PS, ABS modified PS master batch selected as the carrier.

Introduction for some small business:Some kinds of packaging solutions.

Packaging ideas and options are very important for any new business owner producing products, reselling products, or storing products. Packaging is an integral part of marketing and can also help reduce product loss. When determining packaging options, a packaging designer or consultant should be considered. Normally a smart packaging designer is an excellent option to assist in marketing efforts. A professional packaging design will allow products to stand out on the shelves and help build brand recognition. A good packaging consultant is an all-in-one packaging adviser. They will help or know who to recommend for packaging design, efficiency, materials, machines, and a whole host of other issues. Both services are great to consider when sales are high enough to warrant it. 

Many small start-up businesses do not have the option of hiring professionals due to budget constraints. We are going to offer a couple of options to consider. Packaging design is not our specialty, but recommending materials and supplies to small start-up companies is something we often help with.

One of the most cost-effective professional packaging ideas we recommend is a clear plastic packaging material with a professional sticker. For small start-up companies this option is professional, offers low start-up costs, and low material costs. Below is a list of some of our clear plastic packaging options.

1)Poly Tubing: An excellent option for long cylindrical objects. Often used for objects made out of wood or metal. Polyethylene comes up to six mils thick which can handle very heavy and pointed objects. Most companies using poly tubing to package products use a heat sealer to close both open ends.

2)Poly Bags: An excellent choice for a large selection of products from food products to hardware. Poly bags have a lot of versatility from the variety of sizes, thicknesses, and closure techniques. Lay flat poly bags can be closed with tape, staples, twist ties, and even sealed shut. Ziplock poly bags have an easy close top just like home use ziplock bags, but much more cost-effective buying in bulk.

3)Shrink Tubing: Unlike poly tubing, shrink tubing will conform to the product being wrapped. Shrink tubing is not as durable as the thicker poly tubing and is recommended for lighter weight objects. A sealer and a heat tunnel or heat gun works great for shrink tubing.

4)Shrink Wrap Bags/Rolls: Used for consumable and non-consumable products around the world. Shrink wrap offers a great way to cover and protect products while still displaying products for customers to see what they are buying.

Lastly, boxes are one of the most popular options for small start-up enterprises to pack their products. Beware that custom printed boxes are often expensive with high minimum order requirements. Boxes used with the proper void-fill can contain and protect products during transportations and shopping.
