What Are The Features of Retort Pouch Packaging Adhesive YOHO-9870

YH-9870A/B is a universal two-component polyurethane adhesive with a wider range of applicability and higher performance, with high initial tack and high peel strength for composite products.

When used in Plastic-plastic composite products it could withstand 100℃, 30- minute water-boiling sterilization and can be used to make flexible packaging bags that require vacuum and water-boiling sterilization.

It is suitable for aluminum foil, pre-treated BOPP, PET, NY, VMCPP, VMPET, CPP, PE film, and pharmaceutical aluminum foil packaging composite or paper composite.

It can be used for the composite of aluminum foil with various plastic films, but 100℃ aluminum-plastic water-boiling packaging is not guaranteed.

By the way, films to be laminated, need to be treated with corona treatment before application and should have sufficient dynes.

For example: NY, PET ≥ 52dN, BOPP, PE, CPP ≥ 38dN
