28-400 White PP Plastic Ribbed Screw Top Caps with Foil Liner
When properly installed with an induction sealer, the cap's heat sealable liner forms an airtight inner seal that protects contents against moisture and oxygen, and provides a tamper-evident seal. Liner is a paper-backed aluminum foil coated liner with a clear, heat sealable coating that is laminated to a polystyrene foam. Can be used on PE, PET, PVC, PS and PP plastics. Also, may be used on glass treated for proper adhesion. Not suitable for products containing oil. Cap features a smooth top and ribbed sides.
