PET plastic bottles are widely used in beverage, food, household chemical, personal care, and many other packaging applications. Although PET has high recycling value, label materials and adhesive residues can still affect the washing, sorting, and reprocessing quality of recycled PET flakes during the actual recycling process.

Traditional label adhesives are often difficult to remove completely during recycling and washing. This may lead to label residue, adhesive residue, or impurities mixed with PET flakes, reducing the cleanliness and value of recycled PET materials.

To help solve this problem, Sinograce developed WM549 Water-Based Wash-off Label Adhesive. This product is suitable for PP film labels applied to PET bottles. During the PET bottle washing and recycling process, it helps labels separate smoothly from the PET bottle surface, reduces adhesive residue, and improves the recyclability of PET packaging.

WM549 Water-Based Wash-off Label Adhesive

Unlike ordinary label adhesives, WM549 Wash-off Adhesive is specially designed for label applications in PET bottle recycling systems. When used with PP film labels, it helps the label detach from the PET bottle surface under alkaline washing conditions and reduces adhesive residue in the subsequent recycling process.

This product balances normal label adhesion performance with wash-off separation performance during recycling. It is suitable for PET bottle label applications in beverages, food packaging, household chemical products, personal care products, and other packaging fields.
