How to make a 38 mm PET cap

Manufacturers use high strength polyethylene or polypropylene. All covers are manufactured taking into account operating conditions. They withstand repeated use, high liquid pressure inside the container and long storage time.

The 38 mm cap is made in several stages:

  1. Plastification. Raw materials are melted, with the addition of the necessary dye;
  2. Pressing. The resulting mass is molded under high pressure to a uniform density;
  3. Cooling. Rubber pads are added to the cooled two-component products and packed for sale.

Products must not let in carbon dioxide, must tightly wrap around the neck, be safe and environmentally friendly. The preservation of the product depends on the quality of the caps, so it is better to contact trusted manufacturers.
