The types of plastic containers mainly include high density polyethylene, low density polyethylene, polystyrene, polypropylene, etc.
1. High-density polyethylene container: High-density polyethylene blow-molded container is one of the most used in blow-molded products. Polyethylene has low moisture permeability, non-toxic and odorless, suitable for food packaging, but for gas and aroma. Organic vapor is permeable to food. Drugs and chemicals should not be stored for a long time. Generally used to hold liquid detergent, household bleach, table salt, seasoning, milk, sulfuric acid, acetic acid, antifreeze, etc.
2. Low-density polyethylene container: low-density polyethylene is flexible, cold-resistant, moisture-proof, waterproof, and molded. It is easy to burn and the cost of the container is low, so it is widely used. It can be used to manufacture squeeze containers and preserve mucus products for honey, powder insecticides, liquid detergents, and chemical packaging.
3. Rigid PVC container: Rigid PVC has low gas and aroma permeability, oil resistance and chemical resistance. It is combined with acrylonitrile-butadiene-styrene copolymer (abs), a-bromocrotonate (MBS) and other impact-resistant agents to increase its strength and can be used to package food, cosmetics, liquid detergents, etc.
4. Polypropylene container: Polypropylene is an ideal material for making transparent cans. The sheet of polypropylene can be used for making transparent cans, and oriented polypropylene can be used as a transparent hard container.
