HY-753A/753B PU Adhesive for Food Packaging
Overview
KAISHIMEI HY-753A/753B PU adhesive is also a bi-component and solvent base dry-bond lamination adhesive used for bonding food packaging materials such as OPP, CPP, PE, CPE, PET, VMPET, VMCPP, etc. It comes with low viscidity and high solid content. The leveling property of this PU adhesive for food packaging lags slightly behind HY-751.

Referenced Proportion
Generally, HY-753A and HY-753B share the same proportion, namely HY-753A/ HY-753B=100/100. The proportion, however, can be decided according the user’s actual needs. When laminating BOPP to CPP, PE or VMCP, the proportion of main adhesive and curing agent should be 100:100. For other materials with strong barrier property, the proportion can be properly enhanced.
If there is no special requirement, this type of PU adhesive for food packaging features the specific proportion of HY-735A to HY-735B i.e. 100:100.
