Problems solved by technology

[0003] Although the above-mentioned existing labels can achieve the effect of sticking, because the film is made of PVC material, PVC is a kind of toxic plastic, and toxic plasticizers and stabilizers will be added in the manufacturing process. Heavy metals such as cadmium and lead will also be added to it for physical properties; therefore, labels using PVC as film will not only pollute the environment during the manufacturing process, but also ooze toxic substances when used, which is harmful to the human body and is not environmentally friendly.
[0004] In the prior art, environmentally friendly PE film can also be used to replace PVC to make labels, but due to the poor adhesion of PE film, it is not easy to print ink and glue, so pure PE film is not suitable for manufacturing. Labels, although the general EVA has better adhesion, but it is mostly used in foaming materials, tablecloths, shower curtains or raincoats, etc. It is not used as an adhesive film in the field of labels

Embodiment Construction

[0023] The present invention is a non-toxic environmental protection label, please refer to figure 1 , 2 The first preferred embodiment is to include:

[0024] A PEVA film 10, the PEVA film is made by mixing PE (polyethylene) into EVA (polyethylene-vinyl acetate copolymer), and is made by mixing EVA to increase the elasticity and adhesion of PE. The elasticity and adhesion of PEVA film 10 are closer to PVC film than PE film, making PEVA film 10 easier to adhere to the surface of objects;

[0025] In addition, since the PEVA film 10 contains PE and EVA, there is no need to add plasticizers, stabilizers and heavy metals during the manufacturing process, so it is non-toxic and environmentally friendly, and it is not easy to shrink when exposed to heat, unlike PVC films. The problem is that a corona treatment layer 11 is directly formed on the surface of the PEVA film 10 by corona treatment. Through the formation of the corona treatment layer 11, the PEVA film 10 has characteris...

Abstract

The invention relates to a non-toxic environment-friendly label, which is provided with a PEVA membrane, wherein an adhesive layer is formed on the bottom surface of the PEVA membrane, and a release paper is combined with the adhesive layer; and when in use, the release paper is firstly torn out, and then the non-toxic environment-friendly label is adhered onto the adhesive place; and since the PEVA membrane is non-toxic, and the ink adhesiveness and elasticity of the PEVA membrane are better than that of the PE membrane, the non-toxic environment-friendly label has the advantages that the ink printing is easy, and the label is non-hazardous and can protect the environment.

Description

technical field [0001] The invention relates to a self-adhesive label, in particular to a non-toxic and environment-friendly label with a non-toxic diaphragm. Background technique [0002] A general label is made by printing text or patterns on the surface of PVC (polyvinyl chloride) film, and then combining glue and release paper at the bottom of the PVC sheet. When it needs to be used, the release paper is torn off, and then the whole body is fixed on the surface of the object by glue. [0003] Although the above-mentioned existing labels can achieve the effect of sticking, because the film is made of PVC material, PVC is a kind of toxic plastic, and toxic plasticizers and stabilizers will be added in the manufacturing process. And other physical properties will also add heavy metals such as cadmium and lead to it; therefore, labels using PVC as film will not only pollute the environment during the manufacturing process, but also leak toxic substances when used, which is ...
