Cap Liner Type:
F-217® .035” 3-Ply Co-extruded Foam Liner Composition
The F-217 liner is a three-ply co-extruded white liner consisting of a closed cell foam produced from low-density polyethylene (LDPE) faced with solid LDPE on both sides. The opaque white outer skins create a high-quality visual aesthetic. The inner foam core creates a compressible yet resilient product allowing it to create a good seal with the container. 3-ply foam liners have become the industry standard due to their all-purpose compatibility, resilient, compressible seal, cleanliness (no pulp dust) and economy. 3-ply liners are taste and odor resistant, and have a low moisture transmission rate, meaning they prevent moisture from entering the bottle and affecting products. (This liner does not create an airtight seal.)

is a tough plastic that has good chemical resistance. PP is translucent in its natural state but can have a glossy finish when produced with color. Some examples of common products made with PP are dairy and medication containers. Polypropylene is suitable for hot fill applications of up to 165°F and is therefore great for autoclaving. It is not recommended for cold or sub-freezing temperatures. The Cary Company has an assortment of polypropylene plastics available for purchase, such as plastic caps and jars, which have a higher tolerance for chemical products.
