The 68W27Y is a 28mm (28-400 neck finish) continuous thread plastic cap with a .030" three-ply co-extruded polyethylene foam liner (F217 style). This closure is made of polypropylene (PP) plastic and fits our 28-400 vials, bottles, and jars. This plastic cap features a textured (matte) top and a ribbed side. The ribbed-sided design allows for ease of use when removing the lid. The 3-ply foam liner is compatible with many substances and is great for general lining applications.
Cap Liner Type: Uni-Foam US™ .030" LDPE Foam Liner Composition
Uni-Foam US™ 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 there 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.) (Similar to F-217 or SS-222)
Material:
Polypropylene PlasticPolypropylene (PP) 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.
