Pressure Sensitive Liner

Liner consists of multi layers

Induction liner is used to seal the lip of a plastic or glass bottle with heat based adhesive. Its main function is to protect contents in a bottle from humid, oxygen and foreign substances (Tamper evident) and to prevent spilling, extending the reservation period.

Liner consists of multi layers, such as Top Layer, Aluminum, and Seal Layer, and after punching the Liner with proper size, it has to be inserted to use.

The shape of it is round or has an attached opening tap, and there are two types of seal, Peelable and Weld Type. Peelable Seal Type is widely used for the convenient opening.

Application : Screw cap, One touch cap, Flip cap, Food, Pharmaceuticals, Cosmetic, Oil and Chemical products.
Basic composition : Top Layer / Aluminum / Seal Layer
Composition note: 1 PC induction seal can be composed with various materials or plastic substrates as this should be sealable at PE,PET,PVC, GLASS, PP, PS etc

What is foil What is the benefit?

Aluminium foil often referred to with the misnomer tin foil, is aluminium prepared in thin metal leaves with a thickness less than 0.2 mm (7.9 mils); thinner gauges down to 6 micrometres (0.24 mils) are also commonly used.In the foils are commonly gauged in thousandths of an inch or mils. Standard household foil is typically 0.016 mm (0.63 mils) thick, and heavy duty household foil is typically 0.024 mm (0.94 mils). The foil is pliable, and can be readily bent or wrapped around objects. Thin foils are fragile and are sometimes laminated to other materials such as plastics or paper to make them more useful. Aluminium foil supplanted tin foil in the mid 20th century.

Foil made from a thin leaf of tin was commercially available before its aluminium counterpart. Tin foil was marketed commercially from the late nineteenth into the early twentieth century. The term "tin foil" survives in the English language as a term for the newer aluminium foil. Tin foil is less malleable than aluminium foil and tends to give a slight tin taste to food wrapped in it. Tin foil has been supplanted by aluminium and other materials for wrapping food.

Aluminium foil is produced by rolling sheet ingots cast from molten billet aluminium, then re-rolling on sheet and foil rolling mills to the desired thickness, or by continuously casting and cold rolling. To maintain a constant thickness in aluminium foil production, beta radiation is passed through the foil to a sensor on the other side. If the intensity becomes too high, then the rollers adjust, increasing the thickness. If the intensities become too low and the foil has become too thick, the rollers apply more pressure, causing the foil to be made thinner.

The continuous casting method is much less energy intensive and has become the preferred process.For thicknesses below 0.025 mm (1 mil), two layers are usually put together for the final pass and afterwards separated which produces foil with one bright side and one matte side. The two sides in contact with each other are matte and the exterior sides become bright; this is done to reduce tearing, increase production rates, control thickness, and get around the need for a smaller diameter roller.
