Commonly used materials for plastic bottle caps
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. Due to poor oxidation resistance, it is not Wearable. Plastic bottle caps of this material are mostly used for fruit wine and carbonated beverage bottle cap packaging.
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 bottle caps in the field of food packaging will become more and more extensive.
