More Than Packaging — It's a Commitment
In the competitive food industry, packaging is your first handshake with the customer. For glass jars, the lug cap (twist-off) is the gold standard. At its heart lies the Safety Button—a small feature that makes a big sound.
That crisp “POP” isn't just a sound; it’s a scientific confirmation that the product is as fresh as the day it was sealed.
The Vacuum Mechanism
A safety button lug cap is a precision-engineered indicator. Here is how it guarantees safety:
Product is filled & capped while hot.
Internal steam condenses, creating a vacuum.
External pressure flips the button down.
Concave button confirms a secure seal.
