Analysis of various packaging plastics


Due to the impact of the global financial crisis, the growth rate of industrial production in the world has slowed down. However, as the world packaging industry has implemented strong alliances and cross-border cooperation, the world's packaging industry has made new developments, packaging materials and packaging products have grown steadily, packaging new materials, new processes, new technologies and new products have emerged, plastic packaging. Still maintaining a high growth rate. Container bag manufacturer

First, the new polyester packaging dominates: the world's eye-catching polyethylene naphthalate (PEN) is a "new polyester" including materials. Since the molecular structure of PEN is similar to that of PET, and the benzene ring is replaced by a naphthalene ring, PEN has better barrier properties than PET, especially gas barrier, UV resistance and heat resistance (normal amorphous PEN thermal deformation temperature reaches 10007). °C, while PET is only 70 ° C). In the near future, PEN will definitely enter the packaging field in large quantities, triggering another packaging revolution after PET.

Second, new degradable plastics: With the implementation of the international environmental standard ISO14000, new degradable plastics have attracted people's attention. BASF Germany has introduced a degradable polyester resin polymerized with an aliphatic diol and an aromatic dicarboxylic acid under the brand ECOHEXD, which can be used in film production. According to reports, the annual demand for degradable plastics in Western Europe is 20,000 tons. The main application areas are compost bags, garbage bags, plastic film, composite paper, fast food packaging containers and beverage cups.



Third, vigorously develop metallocene plastics: Metallocene is an organometallic coordination compound formed by the transition metal and cyclopentadiene. The metallocene polyolefin is a polymer obtained by polymerizing an olefin with a metalloclocate as a catalyst. Metallocene polymers have many advantages, such as processability, high strength, high rigidity and good transparency, which have attracted great attention and have introduced many new products. Metallocene plastics will directly impact PP, MDPE, LLDPE, and elastomeric plastics. The current demand for PE in the world is currently 40 million tons. It will increase to 50 million tons in 2005, and most of the increase will be metallocene polyethylene. Metallocene plastics have many advantages, such as good gloss, high melt strength and film stability, and are suitable for food packaging, pharmaceutical packaging, shrink film and sanitary products.

 Fourth, foamed plastics go to zero pollution: Italy's A-MUT company's extrusion foam PP film village is the most recent development of foam products. It uses MOH-TELL's high viscosity resin, high melt strength polypropylene (HMSPP), PP homopolymer and low ODP chemical blowing agent to produce foamed polypropylene sheet with fine micropores and even distribution. (EPP). HMSPP for foamed PP only accounts for 12.5%, which has great economic and environmental significance: it has lower product density than PP sheet with the same performance, which can save 20% of raw materials, thus saving 20% of damage. The cost of reimbursement for the ecological environment. The production of foam for packaging is developing along the road of CFC→HCFC→HFC→HC, and is now advancing towards “zero ODP”, “low GWP” and low pollution green technology.

 V. Strong cooperation to open up new land: In 1997, the world's PP production reached 23 million tons, and the competition was fierce. Biaxially stretched PP film has grown rapidly in recent years. In 1997, the world BOPP production capacity reached 2.82 million tons, and in 1998 it increased by 6% compared with 1997. EXXON, PMT, and Bruckner are still the largest and largest manufacturers of biaxially oriented film. The fierce competition in the international market has made companies more grouped, rationalized in production and fierce in competition.
