hight resistance induction seal liner
1. Introduction
Induction lining materials are one of the most important parts in packing industry for sealing the bottles and containers of the products for many reasons. And induction sealing is a simple and reliable method of bottle sealing. It welds an aluminum foil seal across the bottle neck.
2. Main specifications:
- Aluminum foil = 20-40 microns (0.02 - 0.03 mm)
- PE/PET/PP layer = 40-50 microns (0.04 - 0.05 mm)
- Seal backing material: pulp, foam, cardboard,plastic;
- Easy peel and non-easy peel seal available;
- Seal diameters are available from 10 mmto 180 mm;
- With different composition, liner thickness is various from 0.2mm to 1.2mm;
- It can be printed with custom logo, or embossed with any desired design;
3. Main benefits:
- Seals in freshness
- Prevent costly leaks
- Reduce the risk of tampering, pilferage, and contamination
- Extend shelf life
- Create hermetic seals
- Environment friendly
4. They can be used for sealing & packing in the different industries, including:
1- Motor, Engine, and Lubricant Oil products
2- Edible Oil products
3- Medicine products (Pharmaceutical factories for Tablet, Gel, Cream, Powders, Liquids, etc)
4- Food Products
5- Beverages, Fruit Juice, Butter, Honey, Mineral Water
6- Pesticides, Fertilizers, and Chemicals
7- Cosmetics
5. How to use:
Induction lining materials are constructed from aluminum foil membranes, coated with polymer and attached to a backing material by means of wax or polymer bond. This foil laminate is then placed inside a cap or closure, and the closure applied to the container, bringing the foil laminate into contact with mouth of the container.
The container then passes underneath the induction sealing head, where an electromagnetic field creates a low level of localized heat on the foil membrane, which is sufficient to melt both wax bond and polymer coating.
Soon after the container leaves area of the electromagnetic field, the polymer hardens, forming a flexible, yet hermetic seal between foil and neck of the container, while the backing material goes inside the cap as interior liner for more protection
