In the structure of the aluminum foil seal liner, the sealing surface is the sealing layer, and the other side is the backing. What is Backing of aluminum foil seal liner? It is a layer of material with a certain thickness that can be compressed.

Common high-barrier composite films are actually made of a variety of different high-barrier materials to achieve the specified barrier effect after compounding. What are the advantages and disadvantages of these high barrier materials?

Pre-coated film refers to the process of pre-gluing and rewinding the plastic film, and then compounding it with the paper printed product. First, the pre-coated film processing plant will apply the glue on the film and rewind the film according to the specifications and size of the film for the user to choose, and then composite with the printed matter.

Coating Non-woven fabric as a new environmental protection packaging material has gradually entered the packaging industry since 2011. Because of the various styles and exquisite workmanship, the products are sold well throughout the country and the world. The bright color and good texture make it get people’s loves.

Polyester film is a film material made of polyethylene terephthalate as a raw material, made into thick sheets by extrusion, and then biaxially stretched.

To meet the needs of the market, many manufacturers are now taking use of foil heat induction seal liners. It consists of heat sealing layer, aluminum foil layer (induction layer) and backing layer.

Aluminum foil tape is based on high-strength aluminum foil, coated with high-viscosity, high-stability pressure-sensitive glue. The aluminum foil tape is used for the seam bonding of all aluminum foil composite materials, the sealing of the puncture point of the insulation nail and the repair of the damaged part.

The “lamination” actually means the films with different performance stick each other by some ways, and then protect the contents by sealing. The common lamination ways in packaging industry mainly include dry lamination, wet lamination, extrusion lamination, co-extrusion lamination.

The materials used in cable products can be divided into conductive materials, insulating materials, filling materials, shielding materials, and protective layer materials according to their use parts and functions. But some of the materials are common to several structural parts. Especially thermoplastic materials, such as polyvinyl chloride, polyethylene, etc., can be used on insulation or sheaths as long as part of the composition is changed.

The advantages of aluminum polyester film are good deep drawing performance, excellent short-circuit resistance performance, good water barrier performance, better electrolyte resistance and barrier performance, especially in electrolyte corrosion resistance.
