Polypropylene Cap with Liner

F217 has a low density foam core between two solid layers of LDPE. Uses include analytical lab samples, high purity chemicals, strong acids solvents, environmental samples, pharmaceuticals, and diagnostic reagents. Pulp/Vinyl Lined Polypropylene Caps are commonly used for food, beverage, medical and chemical applications packed at less than 120° F., including mild acids, alkalis, solvents, alcohols, oils and aqueous products. Polypropylene caps are known for good impact strength, durability, cost effectiveness, thermal resistance, and pliability.
