Copolymer

At present, some European and American countries have invested heavily in the development of non-polar, polar ethylene copolymers and graft copolymers. This type of product can greatly improve the plastic's stretching and co-extrusion properties, and improve the transparency, seal strength, stress resistance, crack resistance, and enhance the stability of energy, improve the molecular weight distribution and extrusion rheological properties.

Such as C4-LLDPE (linear low-density polyethylene), in the high-speed injection molding process does not damage the screw; C6-LLDPE plastic film toughness and hardness of excellence; HAO C6-LLDPE stretch co-extruded film high quality; C8-LLDPE film toughness special Good; VLDPE (Very Low Density Polyethylene) film has a good flatness, the resin has a low melting temperature, good performance, and good casting performance; C4-VLDPE/VLDPE (ultra low density polyethylene) is suitable for Various plastic film packaging. In the plastic co-extrusion process, mixing LLDPE, can improve the elongation and penetration resistance, LLDPE/LDPE can greatly improve the viscosity and toughness, adding HAO C6-LLDPE and HAO C8-LLDPE can promote rheological stability, hot melt does not break, Plastic film products do not tear and so on.

In the contemporary injection molding process, many countries use VLDPE instead of LLDPE, PP, EVA, PVC. In the extrusion, injection molding, and blow molding processes, VLDPE will occupy the flexible packaging market of medicine, medical care, cosmetics, etc., and further impact the food packaging field.

Metallocene plastics

Metallocenes are organometallic coordination compounds formed by the attachment of transition metals to cyclopentadiene. Metallocene polyolefins are polymers prepared by polymerizing olefins using a metallocene coordination compound (metaL-LOCENE) as a catalyst.

Metallocene polymers have many advantages, such as good processability, high strength, good rigidity and transparency, and have received great attention from people. This type of product is suitable for food packaging, pharmaceutical packaging, shrink film and sanitary products packaging.

Degradable polyester

With the implementation of the international environmental standard IS014000, new degradable plastics have attracted much attention. Among them, BASF has introduced a degradable polyester resin with an aliphatic diol and an aromatic dicarboxylic acid polymer under the brand ECOHEXD, which can be used for film production.

Water-soluble plastic film

Water-soluble plastic packaging film as a novel green packaging material is widely used in the packaging of various products in Europe, America, Japan and other countries, such as pesticides, fertilizers, pigments, dyes, detergents, water treatment agents, mineral additives, washing Agents, concrete additives, photographic chemicals, and gardening chemicals. Its main features are: complete degradation, the final product of degradation is CO2 and H2O, can completely solve the packaging waste disposal problems; safe and convenient to use, it has good mechanical properties, can be heat sealed, and has a higher heat seal strength . At present, Japan, the United States, France and other production and sales of such products, such as the United States WTP company, CCIP company, France's GREENSOL company and Japan's synthetic chemical companies.

The main performance indicators of water-soluble packaging film are:

Moisture content: The rolled water-soluble film is packed in PE plastic to keep its specific moisture content constant. When the water-soluble film is removed from the PE package, its own moisture content changes with the ambient humidity, and its performance also changes.

Anti-static property: Water-soluble film is an anti-static film, unlike other plastic films, with good anti-static properties. In the use of water-soluble film packaging products, it will not affect the plasticity and electrostatic dust-emission properties due to static electricity.

Moisture and gas transmission rate: Water-soluble film has strong permeability to moisture and ammonia, but it has good barrier properties to oxygen, nitrogen, hydrogen, and carbon dioxide gas. These features make it possible to maintain the ingredients and the original smell of the packaged product.

Water-soluble film has also entered the actual production stage in China. For example, the water-soluble film and production equipment jointly developed by Zhuzhou Institute of Technology and Guangdong Zhaoqing Fangxing Packaging Materials Co., Ltd. have been put into production, and its products are moving toward the market.

Our company also main to design Plastic Products, Paper Products, Wooden Products, Household Products, Stationery Products, Sewing Products and so on
