Release Time:2023-01-26
The materials used are polyethylene (PE), polyvinyl chloride (PVC), polyethylene terephthalate (polyester) (PET), etc.

Usually mineral water bottles are made of PVC or PET, carbonated beverage bottles are made of PET, soft drink bottles, liquid food bottles are made of PVC, PE, detergent bottles, cosmetic bottles, milk bottles, lactic acid bacteria beverages are mostly made of PE.

In the early development of bottle caps, cork materials, tinplate crown caps and screw caps were used. Up to now, we have continued to develop aluminum long-neck aluminum caps, carbonated drink aluminum caps, hot-filling aluminum caps, injection aluminum caps, medicine caps, and open-top caps. Type ring caps, safety button claw caps and plastic bottle caps and other products.

Extended information:
The bottle cap is an important part of food and beverage packaging, and it is also the first place consumers come into contact with products.

The bottle cap has the function of keeping the contents of the product sealed, and also has the functions of anti-theft opening and safety, so it is widely used in bottled products, so the bottle cap is the upstream industry of the food, beverage, wine, chemical industry, and pharmaceutical industry. It is the key product of bottle container packaging.

PP bottle caps: mostly used for gas beverage bottle cap gaskets and bottle caps, this material has low density. Heat resistant and not deformed, high surface strength, non-toxic and harmless, and good chemical stability. The disadvantage is that the toughness is poor, it is easy to embrittle under low temperature conditions, and it is not wear-resistant due to poor oxidation resistance. Bottle caps of this material are mostly used for fruit wine and carbonated beverage bottle cap packaging.

PE material caps: mostly used for hot filling caps and aseptic cold filling caps, this material is non-toxic. It has good toughness and impact resistance, is also easy to form film, has high and low temperature resistance, and has good environmental stress cracking performance. The disadvantage is that the molding shrinkage is large and the deformation is severe. Many vegetable oils on the market now, and sesame oil in glass bottles are mostly made of this material.
