Description

A washable removable label (1)

This creation is about a washable removable label, which has good printability and washable removable effect, and no glue residue after removal, can be used as a label for recyclable plastic packaging or glass containers.

In response to rising global environmental awareness and government requirements for waste reduction, many companies have begun to recycle and reuse the plastic packaging shells or glass containers outside the product packaging, because these plastic packaging shells or glass containers are affixed with product labels, and these The label cannot be easily removed, so the recycling rate of these plastic packaging shells or glass containers is seriously affected.

This creation is related to a washable removable label. The pressure-sensitive adhesive layer is a water-soluble pressure-sensitive adhesive layer. The water-soluble pressure-sensitive adhesive layer has excellent water solubility, making the washable removable label After washing with water, it can be easily removed, which can increase the recycling rate of plastic packaging shells or glass containers that use the label to achieve the effect of reducing garbage. Therefore, the label can be removed after finishing this creation.

The technical content of this creation is explained as follows. This description is an example and is not used to limit the scope of patent protection of this creation.

This creation is related to a washable removable label whose structure includes the first A carrier paper layer, a second water-soluble pressure sensitive adhesive layer, and a third release layer.

This creation is related to a washable removable label, in which the material used for the first carrier paper layer includes art paper, woodfree paper, simili paper and kaolin coated paper (clay coated kraft paper), the thickness of which is 40 to 120 microns (μm), and the thickness of 50 to 100 microns (μm) is preferred.

This creation is about a washable removable label, in which the second water-soluble pressure-sensitive adhesive layer is a water-soluble acrylic pressure-sensitive adhesive, which It is a methoxy-containing acrylate copolymer, such as ETERAC77606, a product of Changxing Company; or it is a methoxy-containing methacrylate copolymer. The thickness of the water-soluble pressure-sensitive adhesive layer is 10-30 microns (μm), and the thickness of 15-25 microns (μm) is preferred.

This creation is about a washable removable label. The materials used for the third release layer include paper and plastic film, such as glassine release paper or polyester release film, with a thickness of 35-250 microns (μm) , The thickness of 45~200 microns (μm) is preferred.

Figure 1 is a schematic diagram of the structure of a washable removable label.

As shown in Figure 1, this creation is related to a washable removable label, which is printed into various patterns and die-cut into various shapes, including a carrier paper layer (1), a water-soluble pressure sensitive adhesive layer (2) And the release layer (3).

[Example 1]

The first load-bearing paper layer uses 80 grams per square meter of art paper, and its thickness is 70 microns (μm); the second water-soluble pressure sensitive adhesive layer uses Changxing's product ETERAC 77606 , and its thickness is 20 Micron (μm); the third release layer uses glassine release paper with a thickness of 50 microns (μm) to obtain label products.

[Example 2]

The first load-bearing paper layer is made of molded paper weighing 70 grams per square meter, and its thickness is 100 microns (μm); the second water-soluble pressure sensitive adhesive layer is ETERAC 77606 , a product of Changxing Company, and its thickness is 20 Micron (μm); the third release layer uses a polyester release film with a thickness of 75 microns (μm) to obtain label products.

The label product obtained in Example 1 of the above creation is first torn off the release layer and pasted on the plastic packaging shell, and then immersed in room temperature water. After 10 minutes, the water-soluble pressure-sensitive adhesive layer will be completely dissolved in water , That is, the label can be easily removed after washing with water, and no residual glue is found on the plastic packaging shell after observation, which can fully meet the requirements of plastic packaging shell recycling and reuse.

For the label product obtained in Example 2 of the present creation, the release layer is first torn off and then pasted on a glass container, and then soaked in room temperature water. After 10 minutes, the water-soluble pressure-sensitive adhesive layer will be completely dissolved in water. That is, the label can be easily removed after washing with water, and no residual glue is found on the glass container after observation, which can fully meet the requirements for recycling and reuse of the glass container.

This invention is a washable removable label that has industrial applicability and meets the requirements of a new patent.
