Polypropylene (PP plastic) is another excellent resin variety after the development of nylon, it is a high density, no side chain, high crystallization of linear polymer, has excellent comprehensive properties. Non-textile material is made of thermoplastic fiber under the joint action of adhesive, high temperature and high pressure and other external conditions through special processing, with strong absorption, ductility, softness and flame retardant.
At present, this substance is widely used in the global medical, construction, automobile, agriculture, packaging and other fields. Among many different kinds of plastics, PP, polyester and nylon are the most common raw materials for non-textile production. Data show that the global market value of non-textile products in 2012 was $28.78 billion. Market participants expect the figure to surpass the $45 billion mark in 2019. Its market value will grow at a compound annual rate of 6.7 percent between 2013 and 2019.
In terms of raw materials, in recent years, PP has become the preferred raw material in the global non-textile market. In 2012 PP non - textile products control the global non - textile market share. And polyester, nylon also stand out in the fierce market competition, become second only to PP non-textile important raw materials.
Global PP non-textile sales of $16.43 billion in 2012 are expected to continue to grow in the coming years, with a market value of $25.8 billion expected in 2019. Industry analysis points out that although PP is the largest raw material in demand for non-textile materials, the development of carbon fiber plastics, bio-based fibers, nanofibers will not be underestimated. Perhaps in the near future, these materials are likely to replace PP.
In this regard, the extrusion foamed PP sheet developed by A-MUT 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 polypropylene sheets (EPPs) with tiny pores and uniform distribution of foam. Foaming PP used only 12 HMSPP. 5%, has great economic and environmental significance. Compared with similar products, the foamed plastic product has a lower density and can save 20 percent of raw materials.
Package enterprises vigorously develop metallocene plastics because of the advantages of metallocene polymer, such as good processing performance, high strength, high rigidity and good transparency, so by the packaging industry's great attention, and therefore launched a lot of new products. Metallocene plastic will directly impact PP, HDPE, LLDPE, elastomer plastic market, it is suitable for food packaging, medical packaging, shrink film and sanitary products and other aspects.
In terms of the policy of the development of plastic packaging, the first is to reduce the amount of plastic packaging waste, to reduce the production of plastic packaging waste, should be taken as the primary environmental strategy of plastic packaging. First of all, we should promote the design innovation of plastic packaging, so that plastic packaging can achieve lightweight or thin-walled plastic packaging under the condition of ensuring its basic function. Technological advances in the process of material synthesis to date have made plastics available for this purpose.
