1. Blow the label with a hair dryer and heat the glue under the label to melt, and then it can be easily removed.

2. Tear off a layer of paper on the surface of the label, apply alcohol or gasoline, etc., and then rub the surface with your hands to fully soak in the sticker, and finally wipe it off with a cloth .

3. Hand cream and facial cleanser contain glycerin, silicone, and natural active agents. Glycerin and silicone moisturize and moisturize the skin, and they both have a dissolving effect on glue.

4. You can also use an eraser to remove it.

Extended information

Trademark glue is also called sign silicone. The material itself is silicone, which is an organic synthetic rubber. The main purpose of trademark glue is to press trademark text and pictures on the sheet-shaped film, and then fix the film on the product to be used as a trademark.

Properties

The initial labeling was done by hand, so the requirements for adhesives were not high. Natural glue, animal glue and their modified varieties were generally used. Mainly, such as starch glue, casein glue, natural glue, fish glue, bone glue, etc. Its disadvantages are slow drying, poor initial adhesion, low water resistance, and labels are easy to fall off during transportation and storage.

With the development of science, the packaging of many products is completed on automatic lines, and label pasting is also a part of automation: thus placing higher requirements on label glue. These requirements include:

1. Good initial adhesion, and the label will not fall off, slip or warp after instant pressure is applied.

2. Fast drying speed. Suitable for high-speed automated labeling.

3. After curing, it has high fastness and good toughness, and the adhesive layer will not become brittle or fall off.

4. Non-toxic and pollution-free.

5. Conducive to packaging recycling.

Uses

Trademark silicone can also be used for the printing of plastic toys, electroplating products, electronic toys, trademarks, and irregular patterns. Pad printing rubber head is to use the pattern on the steel plate as a carrier through the rubber head, and then transfer the pattern on the steel plate to the toy product.

Classification

Currently, based on the varieties that appear on the market, adhesives used for label pasting can be divided into three categories: pressure-sensitive adhesives, hydrosols and water-rewettable adhesives. .

1. Generally, pressure-sensitive adhesives have the characteristics of high initial adhesion, long-lasting adhesion, good bonding performance to most packaging materials, and are easy to use. Therefore, they are widely used in label adhesives. , its usage is the largest. Pressure-sensitive adhesives used as label glue generally include acrylate emulsion, rubber emulsion modified products, etc.

2. Water-based label glue uses water as the solvent and is mainly applied and adhered when used. It is more suitable for high-speed automatic production line labeling. Glues for this purpose mainly include polyvinyl alcohol modified glue, casein modified glue, and some polymer emulsions. The D191 type trademark adhesive produced by Shandong Huacheng High-tech Adhesive Co., Ltd. has the characteristics of fast initial positioning, high solid content, fast drying speed, and excellent water resistance. It is very suitable for the use requirements of high-speed labeling production lines.

3. Water-reusable label glue is mainly used for labeling or bonding small packages such as stamps and envelope seals. Some polymer solutions have no stickiness after being coated on the substrate and dry. It becomes sticky again when exposed to water, and this glue is called a water-rewettable adhesive.
