Black Polypropylene Smooth
PE liners have multiple layers that remain in the caps during use. The top and bottom layers of the PE liners are composed of solid low-density polyethylene (LDPE) with a low-density foam core in the middle, creating a liner that is compatible with many products. These liners provide excellent chemical resistance to acids, alkalis, solvents, alcohols, oils, household cosmetics, and aqueous products. They also offer low moisture transmission rates, odor resistance, and do not alter product taste.
