According to Plastic Press Cap Suppliers , plastic bottle caps are generally divided into PP and PE types in terms of materials. PP material: It is mostly used for gas beverage bottle cap gaskets and caps. It is heat-resistant and does not deform, has high surface strength and good chemical stability. The disadvantage is poor toughness and easy embrittlement under low temperature conditions. Wearable. Bottle caps of this material are mostly used for fruit wine and carbonated beverage bottle cap packaging.

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

Plastic bottle caps are generally divided into gasket type and inner plug type. The production process is divided into two types: compression molding and injection molding.

The size is mostly: 28 teeth, 30 teeth, 38 teeth, 44 teeth, 48 teeth and so on. The number of teeth is divided into: 9 and 12 multiples. The anti-theft ring is divided into 8 buckles, 12 buckles and so on. The structure is mostly: separate connection type (also called bridge type) and one-time forming type. Uses are generally divided into: gas bottle caps, heat-resistant bottle caps and sterile bottle caps, etc.

Due to the low cost of plastic materials and the combination of many advantages of materials, it is also welcomed by packaging container material factories to a certain extent. However, because the change performance of its structure is not very clear, it needs to be considered in some food packaging applications. However, with the development of science and technology, the application of plastic covers in the field of food packaging will become more and more extensive.
