Preparation and Properties of PET/PE Solvent-Free Laminated Packaging Films

In flexible packaging solvent-free laminating process, in addition to the quality of the solvent-free adhesive itself, the peeling strength of the laminated product is also determined by many factors. In this experiment, through the control of conditions in the solvent-free laminating process, PET/PE solvent-free laminated film samples were prepared. This work studied the influence of coating weight of adhesive and laminating speed on the quality of laminated films. The results show that the peeling strength increase with the increasing of coating weight and decrease with the increasing of laminating speed, and the coating weight has great influence on peeling strength. The heat-sealing strength and dart impact strength of the sample can also meet the requirements of the national standard.
