Using high quality materials that are FDA approved Pres-On’s foam polyethylene cap seals are excellent solutions for cosmetics packaging, food packaging and general leak prevention. These seals compress easily in the cap to create a stable seal for repeat use. The white, glossy pe foam resists acids, alkalis, solvents, alcohols, oils and aqueous products to keep products where they are meant to be: inside your container.
Pres-On offers multiple thicknesses of our polyethylene foams, most common are the .020 inch and the .040 inch.
