What are the main varieties of containers for plastic products
The main varieties of plastic products containers are high-density polyethylene, low-density polyethylene, polystyrene. Hard polyvinyl chloride, polypropylene, vinylidene chloride, cellulose plastics, polycarbonate, vinyl copolymer, nylon and so on.
A, high density polyethylene container
High density polyethylene blow molding container, is one of the most versatile blow molding products. Polyethylene has low moisture permeability, non-toxic, tasteless, suitable for food packaging, but for gas, fragrance. Organic vapors have permeability to food. Drugs and chemicals should not be stored for a long time. Generally used to hold liquid detergent, household bleach, salt, condiments, milk, sulfuric acid, acetic acid, non-freezing liquid and so on.
Two, low density polyethylene container
Low density polyethylene is soft, cold resistance, moisture resistance, good water resistance, molding. It is convenient to burn, the cost of the container is low, so it is used more. It can make extrusion containers, save mucinous commodities, and be used for honey, powder insecticides, liquid detergents, chemicals and other packaging.
Three, hard PVC container
Hard PVC has low gas and aroma permeability, oil resistance and drug resistance. It and acrylonitrile-butadiene-styrene copolymer (abs), a— Methyl bromocrotonate (MBS) and other impact resistant agents, can improve its strength, can be packaged food, cosmetics, liquid detergent and so on. Hard polyvinyl chloride can also be made into plastic transparent cans or fruit canned containers.
Four, polystyrene container
Polystyrene container, can be thin sheet heat bonding and injection molding. The general polystyrene is transparent, and the impact resistant polystyrene is translucent. Polystyrene containers can be used as packaging for sour milk, sour cheeses, powder chemical seasonings, etc.
Five, polypropylene container
Polypropylene is the ideal material for making transparent cans, polypropylene sheet can be made of transparent cans, oriented polypropylene can be made of transparent hard containers. Polyflumene blow molding containers are often used to hold vinegar, infusion, liquid detergent and so on.
