The type of aluminum foil is selected according to the material of the bottles you sealing. Choose PET type for PET bottles, PE type for LDPE and HDPE bottles, PP type for PP bottles, and glass type for glass bottles.
  • Multiple Sizes According to Convenience Varied size foil liners for induction sealer machines are available. If you need customized size, please contact us.
  • Electro Magnetic Induction Applied For Sealing The induction heat-sealing layer is designed to create a hermetic seal between the cap liner and the bottleneck using electromagnetic induction. When the cap is placed on the bottle and passed through an induction sealing machine, an alternating magnetic field is applied to the cap, causing the heat-sealing layer to melt and bond with the bottle to achieve the effect of moisture-proof and leak-proof sealing.
  • Lightweight Material To Preserve Freshness The foil liner is a lightweight material that is commonly used in food and beverage packaging. The aluminum foil cap liner serves as a barrier layer that prevents oxygen and moisture from entering the bottle, thus preserving the freshness and quality of the contents. Measure the diameter of the bottle mouth and the inner diameter of the bottle cap for the right size.
  • Wide Applications The aluminum foil liner is widely used in the food and beverage industry, pharmaceuticals, and other industries that require airtight packaging. It is suitable for sealing various forms of products such as liquid, solid, semi-solid, capsule, dry powder, granule, syrup, oil, ink, etc.
