Materials such as cigarette packing boxes, wine packing boxes, high-grade gift paper and the like are often compounded with films such as aluminum-plated films or laser films before printing, so that the composite film has a novel and bright appearance effect and a certain anti-counterfeiting function. After the aluminizer or the laser film is combined with the paper, the base film on the surface of the aluminizer or the laser film is generally required to be peeled off by a peeling machine in an off-line state, and the paper after being peeled can be subjected to the next printing work. The scheme for off-line peeling of the base film has the advantages of long product period, low yield and increased peeling machine and labor cost.

In addition, in the printing production process, when the roll material of the paper is about to be used up, another new roll material needs to be spliced with the roll material about to be used up to continue the printing production, and the general printing equipment needs to be stopped to carry out splicing treatment, so that the printing production efficiency is influenced, and the continuous printing production cannot be realized. And moreover, the splicing parts of the paper of the two coil stocks are connected by using the primary adhesive tape, after the paper is compounded with the aluminizer or the laser film and the base film is peeled, the secondary adhesive tape back to the primary adhesive tape needs to be adhered to the splicing parts, the secondary adhesive tape is connected with the two ends of the primary adhesive tape and surrounds the paper and the aluminizer or the laser film on the paper, and the stability of the splicing parts of the paper and the production requirements of the paper adapting to the subsequent printing procedures are further guaranteed.
