Heat Induction Seal Liner (HIS Liner)
Our white plastic screw-top cap with liner features a heat-sealed aluminum liner to ensure customers that their product has not been tampered with. When installed properly, the cap’s heat induction seal forms an airtight inner seal that protects contents against oxygen and moisture and provides tamper-evident proof safety. The liner is an aluminum foil-coated liner with paper on one side and foam. It features a heat sealable coating that is laminated to polystyrene foam. These types of heat induction seals can be used with Polyethylene, PET, PP, and PVC.
In addition, our white plastic screw-top cap with liner is great for a variety of uses for cosmetics and personal care products and is easy to use. The heat seal liner preserves the product for a longer period of time by trapping in oxygen to increase the longevity of products such as lotion, soaps, sanitizers, and more.
*Heat Induction Seals (HIS) are not suitable for products containing oil and HDPE Containers
