What is plastic film

by admin

films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins are used for packaging and as film coating. Plastic packaging and plastic packaging products account for an increasing share in the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical industry and other fields. Among them, food packaging accounts for the largest proportion, such as beverage packaging, quick-frozen food packaging, boiled food packaging, fast food packaging, etc, These products have brought great convenience to people’s life. Film type
PVA coated high barrier film

PVA coated high barrier film is made by coating PVA with nano inorganic matter on polyethylene film, printing and compounding. On the premise of little increase in cost, its barrier performance is not only significantly better than EVOH five layer co extruded film, but also the packaging cost is greatly reduced, This can not only ensure all the quality requirements of the packaged materials for aseptic packaging, but also greatly reduce the cost of aseptic packaging in food processing enterprises. It can be used to package beverages, fruit juice, milk, soy sauce and vinegar

biaxially oriented polypropylene film (BOPP)

biaxially oriented polypropylene film is prepared by CO extrusion of polypropylene particles to form a sheet, and then stretching in both vertical and horizontal directions. Due to the tensile molecular orientation, the film has good physical stability, mechanical strength, air tightness, high transparency and gloss, tenacity and wear resistance. It is the most widely used printing film, with a thickness of 20 ~ 40 μ m. The most widely used is 20 μ m 。 The main disadvantage of biaxially oriented polypropylene film is poor heat sealing, so it is generally used as the outer film of composite film. For example, after compounding with polyethylene film, moisture resistance, transparency, strength, stiffness and printability are ideal, which is suitable for holding dry food. Because the surface of biaxially oriented polypropylene film is non-polar, high crystallinity and low surface free energy, its printing performance is poor and its adhesion to ink and adhesive is poor. Surface treatment is required before printing and compounding

low density polyethylene film (LDPE)

low density polyethylene film is generally made by blow molding and tape casting. The thickness of cast polyethylene film is uniform, but it is most widely used because of its high price and low cost. Low density polyethylene film is a translucent, shiny and soft film. It has excellent chemical stability, heat sealing, water resistance and moisture resistance, freezing resistance and boiling ability. Its main disadvantage is its poor barrier to oxygen. It is often used as the inner film of composite flexible packaging materials. It is also the most widely used and most used plastic packaging film, accounting for more than 40% of the consumption of plastic packaging film

due to the absence of polar groups in polyethylene molecules, high crystallinity and low surface free energy, the film has poor printing performance and poor adhesion to ink and adhesive. Therefore, surface treatment is required before printing and compounding

polyester film (PET)

polyester film is a film material made from polyethylene terephthalate by extrusion and biaxial stretching. It is a colorless, transparent and glossy film with excellent mechanical properties, high rigidity, hardness and toughness, puncture resistance, friction resistance, high and low temperature resistance, chemical resistance, oil resistance, air tightness and fragrance retention. It is one of the commonly used composite film substrates. However, the price of polyester film is high, and the general thickness is 12 μ m. It is commonly used as the outer material of cooking packaging, with good printability

nylon film (PA)

nylon film is a very tough film with good transparency, good luster, high tensile strength and tensile strength, good heat resistance, cold resistance, oil resistance and organic solvent resistance, excellent wear resistance and puncture resistance, soft and excellent oxygen resistance, but poor barrier to water vapor, moisture absorption With high moisture permeability and poor heat sealing, it is suitable for packaging hard goods, such as greasy food, meat products, fried food, vacuum packaged food, steamed food, etc.

films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins are used for packaging and film covering. Plastic packaging and plastic packaging products account for an increasing share in the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical industry and other fields.
