2. Tear off a layer of paper on the surface of the label, smear it with alcohol or gasoline, then rub it on the surface by hand to make it fully saturated with adhesive, and finally wipe it off with a cloth.
3. Hand cream and facial cleanser contain glycerol, silicone and natural active agents. Glycerol and silica gel have moisturizing effect on skin, and both of them have dissolving effect on glue.
4. You can also erase it with an eraser.
Extended data
Trademark rubber, also called logo silicone, belongs to silicone and is an organic synthetic rubber. The main function of trademark glue is to press trademark words and pictures on the sheet-like film, and then fix the film on the product as a trademark card.
nature
The initial labeling is done by hand, so the requirements for adhesives are not high. Generally, natural glue, animal glue and its modified varieties are the main products, such as starch glue, casein glue, natural glue, fish glue and bone glue. Its disadvantages are slow drying, poor initial adhesion and 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 the automation line, and labeling is also a part of automation, which puts forward higher requirements for label adhesive. These requirements include:
1, good initial viscosity, and the label will not fall off, slide down or warp after instant pressure.
2, the drying speed is fast. Suitable for high-speed automatic labeling.
3, after curing, the fastness is high, the toughness is good, and the adhesive layer is not brittle and does not fall off.
4. Non-toxic and pollution-free.
5. Conducive to the recycling of packaging.
use
Trademark silica gel can also be used to print plastic toys, electroplated products, electronic toys, trademarks and irregular patterns. Transfer glue head means that the pattern on the steel plate is used as the carrier through the glue head, and then the pattern on the steel plate is transferred to the toy product.
classify
At present, according to the varieties appearing in the market, the adhesives used for labeling can be divided into three categories: pressure sensitive adhesive, hydrosol and water re-wetting adhesive.
1. Common pressure-sensitive adhesives have the characteristics of high initial adhesion, good adhesion to most packaging materials and convenient use. Therefore, the amount of pressure-sensitive adhesive used as label adhesive is the largest. Pressure-sensitive adhesives commonly used as label adhesives include acrylate emulsion and rubber emulsion modified products.
2. Water-based label adhesive takes water as solvent, which is mainly applied and pasted, which is more suitable for labeling on high-speed automatic production line. This kind of glue mainly includes polyvinyl alcohol modified glue, casein modified glue and some polymer emulsions. The D 19 1 trademark adhesive of Shandong Huacheng Hi-Tech Adhesive Co., Ltd. has the characteristics of fast initial positioning, high solid content, fast drying speed and excellent water resistance, which is very suitable for the use requirements of high-speed labeling production lines.
3. Water-re-wettable label adhesive is mainly used for labeling or bonding small packages, such as stamps and envelopes. Some polymer solutions are not sticky after being coated on the substrate, but they are sticky when exposed to water. This adhesive is a water re-wettable adhesive.
