| Suitable Situations | - Products that require a tight seal- Products intended for long-term storage- Products that need to be frequently opened and closed | - Products that undergo high-temperature processing, like heated canned foods- Products requiring a one-time seal, such as disposable food packaging or industrial chemicals |
| Differences in Specifications | Typically feature continuous threading for tightening or loosening. | Have multiple lugs that match corresponding grooves on the bottle neck, sealed by twisting. |
| Differences in Applications | Widely used for a variety of product packaging. | Primarily used for glass bottle packaging in food and beverages, like canned goods. |
| Usage Considerations | Need to ensure the cap and container threads match to guarantee sealing. | Need to be correctly positioned and tightened to ensure the lugs match the grooves and seal. |
The choice between using Screw Caps or Lug Caps primarily depends on the nature of the product,
packaging requirements, and expected usage scenarios.
Screw caps, with their thread design offering a tight seal,
are very suitable for liquid or semi-solid products that require long-term preservation or frequent opening and closing.
Meanwhile, Lug caps, with their lug design and robust sealing,
are more suitable for solid products and packaging that undergo high-temperature processing, like canned foods.
