The bottle cap is an important part of food and beverage packaging, and it is also the first place where we come into contact with the product.

Bottle heating method The reason why the bottle cap cannot be opened is often because the pressure inside the bottle is lower than the outside of the bottle, and it is difficult to open it under the action of atmospheric pressure.

The surface appearance of tinplate is silvery white or yellow, with metallic luster. Before printing colored text and patterns, the surface needs to be painted white or printed.

The holding pressure is not enough to overcome the strong resistance in the flow channel during the holding stage, so that the pressure in the membrane is insufficient and feeding cannot be performed.

Appearance of the bottle cap: full molding, complete structure, no obvious shrinkage, bubbles, burrs, defects, uniform color, and no damage to the anti-theft ring connecting bridge.

A small sharp protrusion can be seen on the top of some beverage bottle caps, which is used to open the sealed plastic film.
