The main varieties of plastic containers are high density polyethylene, low density polyethylene, polystyrene, rigid polyvinyl chloride, polypropylene, vinylidene chloride, cellulose plastics, polycarbonate, ethylene copolymer, nylon and so on.
First, high-density polyethylene containers
High-density polyethylene blow molding container is one of the most used blow molding products. Polyethylene low moisture permeability, non-toxic, tasteless, suitable for food packaging, but the gas, fragrance, organic vapor permeability, Food, medicines and chemicals should not be stored for a long time, usually used for containing liquid detergent, household bleach, salt, condiment, milk, sulfuric acid, acetic acid and antifreeze liquid.
Second, low-density polyethylene containers
Low-density polyethylene is soft, cold-resistant, moisture-proof, water-resistant and easy to shape, easy to burn, low in cost and therefore versatile for the production of squeeze containers for mucilage products for honey, Body pesticides, liquid detergents, chemicals and other packaging.
Third, rigid polyvinyl chloride containers
Hard PVC has a gas, low aroma permeability, oil resistance, resistance and it and acrylonitrile - butadiene - styrene copolymer (abs ), a-methyl crotonate (MBS) and other impact modifiers to increase its strength, and can be packaged in food, cosmetics, liquid detergents, etc. PVC can also be made into a plastic transparent can or a canned fruit container.
Fourth, polystyrene containers
Polystyrene containers are available in sheet thermal and injection molding. Polystyrene is generally clear and impact-resistant polystyrene is translucent. Polystyrene containers can be used as yogurt, sour cheese, powdered chemical flavoring Materials such as packaging.
Five, polypropylene containers
Polypropylene is the ideal material for making transparent cans, polypropylene sheets can be made from transparent cans, and oriented polypropylene can be used as transparent hard containers. Polyester flame-retardant containers are commonly used in vinegar, infusion, liquid detergents and the like.
