Common reasons why easy open lids cannot be opened normally

Common reasons why easy open lids cannot be opened normally
1. Improper rivet installation. In the production process of the easy-open end, too large or too small rivet installation gap will cause problems when the pull ring is opened. The most common problem is that the pull ring falls off and the lid does not open normally.
2. The depth of the engraved line is not proper. During the production process of the easy-open lid base cover, the depth of the engraved line will also affect the normal opening of the tab. If the engraved line is too shallow, it will usually cause the lid to not be opened normally and the tab to fall off. Scores that are too deep can cause lids to crack and leak during beverage production.
