2. Product Features
● 8899A A variety of high-end polymer Waterborne adhesive, belongs to pollution-free, non-flammable and explosive products.
● 8899A Suitable for the composite of processed polyolefin, polyester and nylon film materials, transparent film, aluminized film and pure aluminum have good composite strength.These composite products can be used in snacks, dry foods, pharmaceuticals, boiled sterilization and other ordinary to high functional requirements of the packaging.
● 8899A After the composite product almost does not produce the core volume false wrinkle.
● 8899A After drying, the adhesive layer has good transparency and high gloss, and the finished product after composite has higher apparent brightness than the solvent-based glue.
● 8899A Even if the curing agent is not added, it also has high composite strength. After the curing agent is added, it can be applied to various structure zipper bag products. When used as a two-component, the recommended ratio is usually 100(main agent): 2(curing agent).
● 8899A Can meet a variety of flexible packaging product structure 100℃/50 minutes of water sterilization, especially aluminum plating products in the water sterilization will not happen Hydrolysis oxidation and transfer of aluminum plating.
●8899A Suitable for a variety of food packaging, pharmaceutical packaging, industrial packaging products, please do a good test before use.
