Seal Bars and Gaskets

Silicone Coated Seal Jaws provide an effective solution for sealing package inconsistencies caused by food contamination, thick or multiple layers of film, product dust or particulate.

The partnership of a rigid, metal surface together with a compliant, silicone tool is an ideal combination for Flexible Packaging (Horizontal and Vertical).
