70-400 Black Ribbed Polypropylene Unlined Cap. Polypropylene caps are known for good impact strength, cost effectiveness, and pliability. Unlined polypropylene caps are suitable for many dry products. Unlike many pre-made closures, there is no glue holding on the liner so the caps are autoclavable. You can also insert your own disc into closures without liners.
