Description

A kind of self-adhesive composite paper label with low carbon and no release liner

technical field

The utility model relates to the technical field of self-adhesive composite paper labels, in particular to a low-carbon self-adhesive composite paper label without release liner.

Background technique

Compared with traditional labels, self-adhesive labels have the advantages of no glue, no paste, no water, no pollution, and save labeling time. They have a wide range of applications and are convenient and fast. Self-adhesive is a material, also known as self-adhesive label material, which is a composite material with paper, film or other special materials as the fabric, adhesive on the back, and silicon-coated protective paper as the backing paper. And after printing, die-cutting and other processing to become the finished label.

A low-carbon non-release liner self-adhesive composite paper label on the market has the following drawbacks: The common low-carbon non-release liner self-adhesive composite paper label is usually used and discarded, which is harmful to the environment. It will cause pollution, and it is easy to be washed and damaged when it encounters water during use, resulting in damage to the information on the surface of the label, which cannot be identified.

Utility model content

The main purpose of the utility model is to provide a low-carbon non-drying backing paper self-adhesive composite paper label, which can effectively solve the problems in the background technology.

To achieve the above purpose, the technical scheme adopted by the present utility model is:

A self-adhesive composite paper label with low carbon and no release liner, comprising a label and a degradable layer, the bottom of the label is provided with a degradable layer, the surface of the label is connected with a waterproof layer, and the main material of the degradable layer is For polyethylene oxide material.

Further, the main material of the waterproof layer is water-solvent polyurethane material, and the waterproof layer made of water-solvent polyurethane and KN-54 high-component water-soluble PU glue can provide waterproof protection on the surface of the label during use, preventing the information in the label. Blurred by water wash, affecting the use of labels.

Further, a glue layer is applied at the bottom of the degradation layer, and the glue layer applied at the bottom of the degradation layer is convenient for sticking and using the label.

Further, oil paper is adhered to the bottom of the glue layer, and the oil paper adhered to the bottom of the glue layer can be directly adhered to the desired use position by simply tearing off the oil paper during use.

Compared with the prior art, the utility model has the following beneficial effects: the degradable layer made of polyethylene oxide as the raw material can be rapidly degraded after the label is discarded after being used, without polluting the environment, and the use of water solvent polyurethane and The waterproof layer made of KN-54 high-component water-soluble PU glue can provide waterproof protection on the surface of the label during use, preventing the information in the label from being washed away by water and blurred, which affects the use of the label.

Detailed ways

In order to make the technical means, creation features, achievement goals and effects of the present invention easy to understand and understand, the present invention will be further described below with reference to the specific embodiments.

As shown in Figures 1-2, a low-carbon adhesive composite paper label without release liner includes a label 2 and a degradable layer 3. The label 2 is provided with a degradable layer 3 at the bottom, and the label 2 A waterproof layer 1 is connected to the surface, and the main material of the degradation layer 3 is polyethylene oxide material.

Wherein, the main material of the waterproof layer 1 is water-solvent polyurethane material, and the waterproof layer 1 made of water-solvent polyurethane and KN-54 high-component water-soluble PU glue can provide waterproof protection on the surface of the label 2 during use, preventing the label 2 The information inside is washed out and blurred by water, which affects the use of label 2.

Wherein, the bottom of the degradation layer 3 is coated with a glue layer 4 , and the glue layer 4 coated on the bottom of the degradation layer 3 is convenient for sticking and using the label 2 .

Wherein, the oiled paper 5 is adhered to the bottom of the glue layer 4, and the oiled paper 5 adhered to the bottom of the glue layer 4 only needs to be torn off after the oiled paper 5 is used, and then the label 2 can be directly adhered to the desired use position.

It should be noted that the present invention is a low-carbon self-adhesive composite paper label without release liner. During operation, the degradable layer 3 made of polyethylene oxide is used as a raw material, which can be discarded after the label 2 is used. , can be quickly degraded without polluting the environment, polyethylene oxide, is an organic compound, no special odor, is a crystalline, thermoplastic, water-soluble polymer, with a linear and regular spiral structure, commonly used as water-soluble It is used as a thickener for adhesives, using boiling water to dissolve or dissolve polyethylene oxide in a non-aqueous solvent that is compatible with water for dispersion. The waterproof layer 1 made of -54 high-component water-soluble PU glue can provide waterproof protection on the surface of the label 2 during use, preventing the information in the label 2 from being washed away by water and blurred, which affects the use of the label 2. Water-soluble PU glue is a kind of Based on anionic water-based polyurethane dispersion, it is a heat-activated adhesive with the advantages of environmental protection, high efficiency and saving. The sticking oiled paper 5, when in use, only needs to tear off the oiled paper 5, and then the label 2 can be directly adhered to the required use position, and the material layers are all arranged inside when the label 2 is produced. Description, Gu do layered instructions.
