Aluminum PP (polypropylene) Caps Classification

Polypropylene bottle caps can generally be divided into two types : PP-H and PP-C, and their characteristics are introduced below :

  • PP-H bottle cap : PP-H is a kind of modified polypropylene, which has excellent high temperature resistance and rigidity, and is suitable for the manufacture of high temperature sterilized bottle caps. Its processing temperature is generally above 230°C. The processed product has high mechanical strength and high temperature resistance, and is suitable for the manufacture of bottle caps in the fields of medicine and cosmetics.
  • PP-C bottle cap : PP-C is a kind of ordinary polypropylene, which has excellent transparency and softness, and is suitable for the manufacture of bottle caps with small caliber and good airtightness. Its processing temperature is generally around 200°C, and the processed product has good softness and tightness, and is suitable for the manufacture of bottle caps in the fields of food and beverages.

Depending on the field of application, aluminum alloy and polypropylene caps can be classified. The following are common classifications with their corresponding alloys, tempers and examples :
