In the case of aluminum-plastic cap specifications, salt bottles with different diameters should be selected and appropriate caps should be chosen. The shape of aluminum-plastic caps is generally multi flat, and the shape after capping depends on the capping die of the capping machine. If the mother and child are sealed to form an aluminum-plastic cap with a flat top shape, the bottle stopper often cannot be tightened, which can easily cause loosening.

The aluminum-plastic cover does not come into direct contact, and some people believe that its cleanliness should not be overly demanding.
