Everything You Need to Know About Screw Caps

What Are Screw Caps?

Screw caps are a type of closure designed to ensure the secure sealing of products using a screw mechanism. These caps are typically opened and closed using threaded cap systems and prevent leakage of various liquid and solid products. Screw caps are designed to provide a tight connection between the cap and the packaging, offering high security and leak prevention.

How to Use Screw Caps

Using screw caps generally involves the following steps:

• Placing the Caps: The screw cap is placed onto the opening of the product, and the screw mechanism tightly fits between the cap and the packaging. This mechanism ensures a secure connection.
• Opening the Caps: Screw caps are opened by turning them counterclockwise. The cap is unscrewed to access the contents inside.
• Closing the Caps: After use, the cap is screwed back on tightly. The screw mechanism fills the gap between the cap and the packaging, providing a secure seal and preventing leakage.
