56MM HDPE Induction Sealing Wad offers numerous benefits to companies that use this type of sealing on their product packaging. First and foremost, induction seals provide tamper evidence. Because there is a heat seal that offers a layer of protection, the seal provides a secure seal that allows tampering to easily be identified. Secondly, 56MM HDPE Induction Sealing Wad preserves the contents inside the packaging by preventing oxygen and moisture from entering the package. After the bottle has been filled and sealed, the foil disc is placed inside the cap, and the bottle is then put through an induction sealer.
