Plastic Caps using Foamed Polyethylene (F217)
Used with all of our plastic caps. F-217 is a soft polyethylene foam core covered on top and bottom with solid, clear polyethylene supplied in .050” thickness. F217 has become the industry standard due to its all purpose compatibility, resilient, compressible seal, cleanliness (no pulp dust) and economy. F217 liners have excellent chemical resistance and a low moisture transmission rate. F217 also has good taste and odor resistance.
