These heat-sealable, hygienically food-grade 4” x 4” sheets are the perfect solution for high end waxes and similar concentrates. More and more concentrate producers are turning to FEP Clear Non-Stick Sheets for concentrate packaging.

These FEP sheets are also completely transparent which is ideal for the extractor who takes pride in the product.
