An aluminium foil induction liner is a bottle cap sealing material composed of a layer of aluminium foil laminated to a flexible cardboard substrate. When placed inside the bottle cap and heated using an induction sealer, it forms a secure, professional seal around the bottle opening. This aluminium foil induction liner is suitable for PET plastic bottles, cans, drums and glass bottles, and is widely used for the sealed packaging of condiments, detergents, toiletries, hair care products, as well as various powders, solids, liquids and oily products.

1 .What is the difference between an aluminium foil induction liner and a standard gasket?
Standard gaskets provide only physical separation, whereas aluminium foil induction liners fuse with the bottle neck via induction heat sealing, resulting in a stronger seal, tamper-evident properties, and a more professional and reliable seal.
2 .Are induction liners suitable for all types of bottle caps?
These induction liners are primarily suitable for PET plastic bottles and glass bottles. Compatibility with metal caps and metal bottle necks must be confirmed based on the specific materials involved.
3 .Can induction liners be used without an induction sealer?
Induction liners require electromagnetic induction heating generated by an induction sealer to achieve an effective seal. Without an induction sealer, aluminium foil induction liners cannot form a secure heat seal.
4 .Can induction liners be reused?
Aluminium foil induction liners are single-use sealing materials. Once opened, the aluminium foil layer is compromised and cannot be resealed; this also serves as a tamper-evident feature.
5 .How can I confirm that the induction liner is the correct size?
Please first measure the inner diameter of the bottle cap accurately, then refer to the product specification table to select the corresponding size. We recommend allowing a tolerance of ±1mm.
