The Pingyuan County Chemical Research Institute of Shandong Province and Sichuan University successfully developed a water-soluble hot compound glue for bridge type heating laminating machines and a high-strength water-soluble paper-plastic adhesive to solve the packaging and printing industry to some extent. Contamination problems due to the use of benzene solvents.
Bridge-type warming laminating machine special environmental protection type water-soluble hot complex glue water referred to as water-based hot complex glue. Its advantages are non-toxic, odorless, non-flammable, high brightness, high viscosity, good adhesion, and small dosage. Only 9g of glue per square meter of laminated film can achieve the ideal laminating effect, drying to 60 -80 degrees is the most appropriate.
