How to remove offset printing from plastic boxes. Most label adhesives are pressure-sensitive adhesives. Pressure-sensitive adhesives are also known as self-adhesive label adhesives, often referred to as self-adhesive glue. They are made of paper, film or special materials, coated with pressure-sensitive adhesive on the back, which is a composite material coated with silicone protective paper. The adhesive of self-adhesive adhesive includes base material, tackifying resin, etc. According to the principle of chemical isomorphism of polymers, the base material or tackifier of the self-adhesive adhesive is diluted with an appropriate solvent to make it easy to separate from the attached object. According to the composition of the above-mentioned self-adhesive agent, it can be known that the components in the pressure-sensitive adhesive are organic polymer compounds in the chemical field, and the viscosity is relatively high. According to the principle of isostructural compatibility of polymer chemistry, as long as it is an organic solvent, the above-mentioned polymer compounds can be dissolved. For example, wine, wind oil, alcohol, gasoline or nail polish thinner are all organic solvents, such as facial creams and facial cleansers. Additionally, milk, cleansers and hand creams have the same effect.
