Polypropylene Caps

Polypropylene Caps

Polypropylene caps are known for good impact strength, durability, cost-effectiveness, thermal resistance, and pliability. Polypropylene unlined caps are autoclavable. Wide-mouth PP caps are well-suited for many dry products. Choose unlined polypropylene caps or with various liners, including polyethylene (PE Foam & F217), Pulp/Vinyl, F217 & PTFE, or acid-resistant F-422 liners. Add a PTFE disc liner to the unlined polypropylene cap for better leak resistance when Autoclaving.
