Screw Cap 28-400 Black Finish with PE Foam Liner - Sample


The 28-400 Electrolytic Tinplate Screw Cap, characterized by its black exterior and gold interior, is specifically crafted for compatibility with bottles featuring a 28/400 thread. This continuous thread (CT) cap incorporates a Polyethylene (PE) foam liner within. This liner, made of low-density polyethylene (LDPE), ensures a stable and effective seal with a low moisture transmission rate and resistance to taste and odor. These foam liners achieve a seal through the compression between the cap and the jar, ensuring the freshness and integrity of the product inside.

These threaded metal caps are 100% recyclable. The combination of a secure seal and recyclability positions this type of closure as a preferred choice for both sustainability and preservation in the packaging industry.
