Description

A double-layer PETG heat-shrinkable film battery label

technical field

The utility model relates to a battery label, in particular to a double-layer PETG heat shrinkable film battery label.

Background technique

At present, many household electronic products, such as flashlights, remote controls, toys, clocks, etc., all use dry batteries as power sources. The battery label is used to record the performance of the battery itself and relevant information on production information, and at the same time, it can isolate the battery surface from other substances outside the battery and play an insulating role. The battery label is usually a rectangular adhesive labeling paper, which is surrounded and pasted on the outside of the battery body by a special tool to form a complete battery.

The gloss and wear resistance of battery labels are important indicators for judging the quality of battery labels. In order to improve these two indicators, some battery label manufacturers have designed labels with a protective layer on the surface, but the coating production process is harsh and cumbersome, which not only increases Costs also reduce production efficiency. In addition, the material selection and process control of battery labels must comply with the environmental protection requirements under the new situation.

Therefore, the main problem faced by those skilled in the art is: how to provide an optimal solution to design a battery label with excellent properties such as high gloss, good wear resistance, environmentally friendly materials, and simple process.

Utility model content

The implementation of the utility model solves the problems mentioned above. The battery label can not only ensure glossiness and abrasion resistance, but also has environmental protection and degradability, and does not require excessive cost and complicated production process.

The technical scheme adopted by the utility model to solve the above-mentioned problems is: a double-layer PETG heat-shrinkable battery label, including a release paper, characterized in that: the release paper is provided with a pressure-sensitive adhesive layer, and the pressure-sensitive adhesive layer A bottom film layer is arranged above the sensitive adhesive layer, a top film layer is arranged on the bottom film layer, and an ink layer formed by ink printing on the top film layer is arranged on one side of the top film layer. A composite adhesive layer is arranged above the bottom film layer, and is composited with the ink layer. The ink is water-based gravure ink. The base film is a PETG heat-shrinkable film, preferably, a PETG opalescent film or a PETG metallized film. The top film is a PETG transparent heat-shrinkable film containing reinforcement factors. This type of battery label can be completed on a continuous production line. The bottom film coating and top film printing are carried out at the same time, and then compounded. Not only the process is simple, but the production efficiency is extremely high. At the same time, the PETG transparent film containing the enhancement factor is used as the top film layer, which can ensure the gloss and wear resistance of the label, and the PETG film is a modified degradable environmental protection material, which avoids the harm of white pollution and reduces the pressure on environmental protection.

Preferably, a pressure-sensitive adhesive layer is arranged under the bottom film layer, so as to facilitate the sticking of the battery label to the battery without residual glue.

Preferably, the ink is water-based gravure ink. The ink is clean and environmentally friendly, has good adhesion, and has the characteristics of alkali corrosion resistance and weather resistance. At the same time, the ink layer is located inside the top film layer, which prevents the ink layer from being scratched.

Preferably, the top film layer is a PETG transparent heat-shrinkable film containing reinforcement factors. The film contains nano inorganic reinforcing particles, which are located on the top layer of the label, ensuring that the label has the characteristics of high transparency, good gloss, strong abrasion resistance and excellent degradability.

Preferably, the thickness of the bottom film layer is no more than 30um, the thickness of the pressure-sensitive adhesive layer is no more than 22um, and the thickness of the top film is no more than 25um, so as to ensure that the thickness of the attached battery label is no more than 80um.

Preferably, the top film layer and the ink layer are combined with the bottom film layer through a composite adhesive layer. Ensure the composite strength of the battery label.

Preferably, the composite adhesive is a solvent-free polyurethane adhesive, which is clean and environmentally friendly, and has strong viscosity.

Compared with the prior art, the utility model has the advantages that the production process of the double-layer PETG heat-shrinkable battery label is simple, and the existence of the PETG transparent heat-shrinkable top film layer containing the enhancement factor ensures the glossiness and wear resistance of the label. At the same time, PETG heat shrinkable film is a degradable green material, and the adhesives and inks used are non-toxic and harmless environmental protection materials.
