The 3-Ply Foam Cap Liner, manufactured to industry standards, is a three-layer bonded liner consisting of a polyethylene foam core bonded between two facing layers — typically a solid polyethylene backing and a product-contact face layer. This construction delivers a tighter, more consistent seal than single-layer alternatives, reducing the risk of leakage and maintaining product freshness over time.

This style liner is one of the most commonly specified liners in the food, beverage, nutraceutical, and chemical packaging industries. It is compatible with a wide variety of screw caps and offers good resistance to moisture and many non-aggressive chemicals. As a Canadian supplier with volume inventory and short lead times, Nextech Packaging is a reliable source for this essential packaging component.
