Problems solved by technology

However, the OPS material is polystyrene, and the ink used is a special benzene-containing ink. The label production process is not environmentally friendly. Today, with increasingly stringent environmental protection policies, the large-scale promotion of OPS labels is restricted.
Simply using PETG shrink film (regardless of high shrinkage or low shrinkage) is difficult to achieve shrink packaging of special-shaped bottles. Therefore, we propose a PETG label production process that can be used to replace OPS shrink labels on special-shaped bottles to solve the above problems

Abstract

The invention relates to the technical field of PETG label production, in particular to aproduction process of a PETG label used on a special-shaped bottle to replace an OPS shrink label, and the PETG label production process comprises the following steps: S1, preparing an intaglio roller for pattern deformation pretreatment according to the shrinkage characteristic of a low-shrinkage PETG original film, wherein and the depth of the roller is 45 microns; s2, carrying out transfer printing on the low-shrinkage PETG original film by using acrylic acid system ink by means of a plate roller; s3, after printing is completed, coating the upper portion and the bottom of the pattern with an acrylic acid system shrinkage reinforcing agent; s4, after printing is completed, carrying out slitting, palm sealing and product inspection. According to the PETG label production technology, PETG material printing ink is ester soluble ink or water-based ink, and the printing process is non-toxic and harmless. The problem of environmental protection is effectively solved, and characters and patterns are neat and free of deformation after contraction.

Description

technical field [0001] The invention relates to the technical field of PETG label production, in particular to a PETG label production process used to replace OPS shrink labels on special-shaped bottles. Background technique [0002] In the field of plastic shrink labels, OPS shrink labels can meet the characteristics of special-shaped bottles to achieve 360° full fit, firm appearance, and no wrinkles. However, the OPS material is polystyrene, and the ink used is a special benzene-containing ink. The label production process is not environmentally friendly. Today, with increasingly stringent environmental protection policies, the large-scale promotion of OPS labels is restricted. Simply using PETG shrink film (regardless of high shrinkage or low shrinkage) is difficult to achieve shrink packaging of special-shaped bottles. Therefore, we propose a PETG label production process that can be used on special-shaped bottles instead of OPS shrink labels to solve the above problems....
