There are two forms of aluminum foil in container sealing: aluminum foil for induction sealing and aluminum foil for bottle cap. What are they and their properties? Lets have a look together.
The electromagnetic induction aluminum foil sealing film is composed of cardboard, aluminum foil, adhesive, sealing film, etc., and the thermal adhesive layer is sealed with the bottle mouth by means of non-contact heating with an electromagnetic induction sealing machine. After induction heating, the pad paper is separated, and the aluminum foil sealing layer is sealed with the bottle mouth to achieve the effect of sealing.
It is widely used for sealing and packaging of pesticides, medicines, health products, beverages, office consumables, cosmetics and other products. It is applicable to those containers: PET, PE, PC, PP, PS, PVC, glass bottles, etc.
Aluminum foil is a hot stamping material that is directly rolled from metal aluminum into thin sheets. 1235 and 8011 aluminum foil are often used. Aluminum foil has good sealing performance and good impermeability. The surface of the aluminum foil is clean and will not grow or adhere to bacteria, meeting hygiene and environmental standards.
In recent years, aluminum bottle caps are more and more widely used in our daily life, especially the packaging of wine, beverage and medical and health care products. Aluminum bottle caps are simple in appearance and fine in production. Advanced printing technology can meet the effects of consistent color and exquisite patterns, bringing consumers an elegant visual experience.
Aluminum bottle caps are mostly processed in production lines with a high degree of automation, so the requirements for the strength, elongation and dimensional deviation of the aluminium foil bottle cap are very high, otherwise cracks or creases will occur during processing.
