starch-based eco cutleries

Single cap (with a cylindrical seal inside, almost all drinks can be used);

Double cap (there is a soft cushion inside, often used by Sprite and Coke);

The two types of bottle cap sealing principle and sealing structure are different:

The single cap depends on the sealing ring, top seal, side seal three structures to ensure the sealing effect, of which the sealing ring is necessary, the side seal and the top seal according to the requirements of the sealing effect and the design requirements of the cap structure, can choose not to. Through the three structures of sealing ring, top seal and side seal, the contact channel between the inside and outside of the bottle is isolated from the inside, top and outside of the bottle mouth. If the thread is needed to seal, the contents can fill the thread gap between the cap and the mouth of the bottle, and no longer leak out.

A small starch-based eco cutleries weighs no more than a few grams and costs no more than a few cents, but behind the product is the entire industrial strength of the country. Including but not limited to:

Petrochemical industry: The material of the bottle cap is mainly PE, PP, and special plastics such as the inner liner in the double cap, which are required to be food grade. Mold manufacturing occupation: Bottle cap production mold is divided into injection mold and pressure plastic mold two kinds.

Large-scale production management ability and quality management ability: a bottle cap price of a few cents, only large-scale production can produce satisfied profits, machinery, personnel, automation and so on the factory management ability requirements are getting higher and higher. The machine produces hundreds of thousands of bottle caps a minute a day, to ensure that the quality of each product meets the requirements, quality management ability and professional ability requirements and other ordinary occupation is not a level.
