The aluminum foil will melt and closely bond with the bottle mouth, becoming a relatively strong barrier that can effectively prevent direct contact of the product with outside air to avoid oxidation, deterioration and other issues. Aluminum foil moisture-proof effect is good, you can block water vapor penetration effectivly and prevent the product from getting damp. In liquid or paste products, aluminum induction seals act as a great barrier to prevent any leaking, preserving the product unchanged.

Aluminum Induction Seals are conductive to heat and seal well, the basic choice. The strength, barrier property or special functions (like easy tearing and anti-counterfeiting) can be achieved by compounding of other materials (for examples: paper, plastic etc.) on the surface of aluminum foil. Different shades and designs can be achieved by way of printing or coating that add beauty to the product.

By extending product shelf life, these seals offer a relatively inexpensive way to preserve your product.
