Introduce:Plastic cover is generally based on polyolefin as a major raw material, after injection molding, hot pressing and other process processing. Plastic anti-theft cover requires convenience to consumers, and avoid leakage problems due to poor sealing performance
In terms of material, it is generally divided into PP class and PE class.

PP material class: mostly used for gasket and bottle cap of gas drinks, heat resistance and no deformation, high surface strength, good chemical stability, the disadvantage is poor toughness, easy embrittlement under low temperature conditions, because of poor oxidation resistance, and not wear resistance.

This kind of cap material is used for fruit wine, carbonated drinks bottle cap packaging.

PE material class: mostly used for hot filling bottle caps and aseptic cold filling bottle caps, this material is non-toxic, has good toughness and impact resistance, but also easy to form film, high and low temperature resistance, environmental stress cracking performance is good, the disadvantage is forming shrinkage, severe deformation.

Now on the market a lot of vegetable oil, glass bottles of sesame oil and so on more is this kind of material.

Plastic bottle cap is generally divided into gasket type and plug type.

Production process is divided into two kinds: pressure molding and injection molding.

The size is mostly: 28 teeth, 30 teeth, 38 teeth, 44 teeth, 48 teeth, etc.

The number of teeth is divided into: multiples of 9 and 12.

Anti-theft ring is divided into: 8 buckle, 12 buckle, etc.

The structure is: the separation connection type (also called even bridge type) and a into the type.

Uses are generally divided into: gas caps, heat - resistant caps and sterile caps.

Because the plastic material cost is low, concentrated the advantages of a lot of material at a suit, also welcomed by the packaging container materials plant, to a certain extent, but due to the change of the structure performance is not very clear, in some food packaging applications must also consider, but with the development of science and technology, plastic cover will be more and more widely applied in the field of food packaging.
