White polypropylene caps have a smooth surface and feature an HSS-5.6/20 universal foam induction liner. This liner provides tamper evidence and reads "Sealed for Your Protection." To adhere the liners to the containers, the plastic caps must be applied using an induction cap sealing system such as our Enercon Super Seal Jr. Here you will find a selection ranging in size from 28mm to 48mm. These caps are offered at wholesale pricing in bulk for the best discounts.
