What are the types of materials for plastic packaging bags?

Plastic is an indispensable material in our modern society, ranging from satellites and airplanes to mobile phones and ballpoint pens. Plastics can be seen everywhere, and these plastics are petrochemical products. Plastic film is one of the varieties, and plastic bags are storage bags made of plastic films. There are roughly five kinds of plastics made of plastic bags: (1) Polyvinyl chloride (PVC) In the 1950s and 1960s, most of my country's plastic bags were made of polyvinyl chloride, because they contained additives to improve processing performance and improve processing performance. Plasticizers with flexible films, these additives are toxic and are not suitable for food packaging, so they are rarely seen in the market except for special non-toxic hard films used for packaging. (2) Low-pressure polyethylene (HDPE) HDPE film is generally used in places requiring high stretching and anti-seepage. HDPE films are also commonly used in merchandise bags, grocery bags and food packaging. In daily life, commodity bags that require high strength, good waterproofness and good impermeability are all made of this product. (3) The film made of high pressure polyethylene (LDPE) LDPE has good optical properties, strength, flexibility, sealing, slow odor diffusion and chemical stability. Because of its excellent performance and processability, coupled with its non-toxicity and relatively low price, most of the plastic bags currently used are such products. ⑷ Polypropylene (BOPP) BOPP film is the abbreviation of biaxially oriented polypropylene film. It is a very important flexible packaging material. It is colorless, odorless, tasteless, non-toxic, and has high tensile strength, impact strength, rigidity, Strong toughness and good transparency. After corona treatment, BOPP film has good printing adaptability and can be printed in color to obtain exquisite appearance effect, so it is often used as the surface layer material of composite film. Now colorful food, cold drinks packaging films are made of BOPP. ⑸ Other plastic films: polyester, polystyrene and composite films, etc. Paper Plastic Packaging Co., Ltd. specializes in the production of various paper plastic color printing packaging, including stand-up bags, zipper bags, vacuum bags, plastic bags, food packaging bags, food bags, aluminized bags, aluminum foil bags, and other products.
