Quality Inspection For Bags For Postage - Aluminum Foil with Customizable Thickness And Color – Gooban

Product Characteristics

The advantage of aluminum foil composite material is that it can block oxygen and moisture well, and the water permeability and oxygen permeability are both 1, so it is a good barrier material. In addition, aluminum foil has good heat resistance, good light reflection and gloss, and good shape at high and low temperatures. The aluminum foil itself is waterproof, airtight and light tight. It can protect the butyl adhesive layer from environmental impact and greatly improve its natural aging resistance.

Aluminum foil is a perfect material with many excellent properties, which fully shows its broad application prospects in many fields.
