core tip: according to the report of Cleveland industry market research company, the global demand for plastic bags will grow at a rate of 6.2% per year, and the total market demand will reach US $37.3 billion by 2018. The growth of this value is caused by the traditional consumption of consumers and producers. Now the static friction coefficient and dynamic friction coefficient of plastic film and sheet, rubber, paper, escort belt, tire and other materials when sliding are all required to be measured well. The market is more inclined to the traditional plastic packaging form, which can be said to be a kind of market consumption inertia at the same time

[China Packaging News] according to the report of Cleveland industry market research company, the global demand for plastic packaging bags will grow at a rate of 6.2% per year, and the total market demand will reach US $37.3 billion by 2018. The growth of this value is caused by the traditional consumption preferences of consumers and producers. The market is more inclined to the traditional plastic packaging form, which can be said to be a kind of market consumption inertia

the expansion of packaging bag production scale and market demand

in China and other developing countries with rapid market expansion, the expansion of packaging bag production scale and the continuous rise of market demand show a complementary trend. The report shows that by 2018, the market revenue in the Asia Pacific region is expected to be the highest. Among them, food packaging (especially beverage packaging) and drug packaging will be the two main growth poles

extruded foamed PP sheet of Italian a-mut company is the latest development of foamed plastic products. It uses moh-tell's high viscosity resin, high melt strength polypropylene (HMSPP), PP Homopolymer and low ODP chemical foaming agent to produce foamed polypropylene sheets (EPP) with fine pores and uniform distribution. HMSPP used in foamed PP accounts for only 12.5%, which is of great economic and environmental significance: compared with PP sheets with the same performance, it has a low product density, which can save 20% of raw materials, thus saving 20% of the expenses to be paid for destroying the ecological environment. The production of foamed plastics for packaging is developing along the road of CFC HCFC HFC HC, and is now advancing towards a green process with zero ODP, low GWP and low pollution

because metallocene polymers have many advantages, such as good processability, high strength, high rigidity and good transparency, they have attracted great attention in the packaging industry, and many new products have been launched. Metallocene plastics will directly impact the markets of PP, HDPE, LLDPE and elastomer plastics. It is very suitable for food packaging, pharmaceutical packaging, shrink film and sanitary products

bio based plastics

biodegradable plastics are plastic materials made of plant straw, starch, etc. different from the three synthetic plastics, they can decompose by themselves under the action of biological environment. They are harmless to people and the environment, and belong to green packaging

as a pioneer of Biodegradation Technology in the industry of widely used plastic apparent density: determination standard astmdl662, Australian plantic Technology Co., Ltd. has become famous at home and abroad. It produces a series of biodegradable plastic packaging materials, 90% of which are corn starch. If you put this material in water, it will disappear from your sight in a few seconds. It can be directly contacted with greasy food and even eaten directly

bio based plastic packaging can effectively regulate the degradation time and cycle of bioplastics, and reduce and eliminate the pollution and impact of plastic packaging materials on the ecological environment while giving full play to the function of bioplastics packaging materials. Take advantage of the edible and water-soluble characteristics of some plastic packaging materials to reduce the amount of packaging waste and improve the safety and environmental protection performance of plastic packaging

recently, Xinjiang production and Construction Corps and Jinfa technology signed a three-year agreement to promote fully biodegradable plastic mulch. In 2014, 140000 mu of farmland in 14 divisions of the Corps used fully biodegradable plastic mulch, and in 2016, it will be used in 6million mu of farmland. Fully biodegradable plastic film is a new type of film produced to meet the needs of society for environmental protection. The main raw materials are biodegradable masterbatch and plastic particle masterbatch

the harm of plastic packaging still needs attention

after entering the environment, waste plastic packaging is difficult to degrade, resulting in long-term and deep-seated ecological environmental problems. First of all, waste plastic packaging mixed in the soil will affect the absorption of nutrients and water by crops, which will lead to crop production reduction; Second, waste plastic packaging discarded on land or in water is swallowed by animals as food, resulting in animal death; Third, the waste plastic packaging mixed with domestic waste is difficult to deal with: landfill treatment will occupy land for a long time, the domestic waste mixed with plastic is not suitable for composting treatment, and the sorted waste plastic is also difficult to recycle because its quality cannot be guaranteed

with the development of science and technology and the improvement of living standards, various kinds of plastic waste are constantly produced. According to foreign media reports, more than 5trillion plastic fragments float on the oceans around the world, and their weight is equivalent to two large cruise ships. Such a huge number is undoubtedly a warning to us

ocean currents and winds drive these plastics around the world's oceans, and many plastics are concentrated in five huge ocean circulations in the northern and southern Atlantic, northern and Southern Pacific, and Indian Ocean. Although the amount of plastic input in the southern hemisphere is much less (due to the small number of coastal residents), the degree of plastic particles accumulated in the circulation in the southern hemisphere is similar to that in the northern hemisphere

with the help of towing, researchers salvaged plastic debris from five subtropical circulations (large-area circulating currents) and the coast of Australia, the bay of Bengal and the Mediterranean Sea. These visual surveys provide information about large pieces of plastic. Scientists combined these data and, with the help of a computer simulation of the dispersion of floating debris, determined that the ocean contained at least 5.25 trillion plastic fragments, with a total weight of 268940 tons. These plastic fragments range from tiny particles with a diameter of less than 1 mm to huge fragments with a diameter of more than 8 inches (20 cm). As we all know, subtropical circulation will gather plastic debris together, but this study found that plastic waste is not limited to these marine garbage bins. The smallest plastic particles are distributed in some remote areas of the world, such as the sub polar region, which means that the circulation will tear up large pieces of plastic like a paper shredder and spread smaller pieces to other areas
