What does self-adhesive paper mean? Does it do anything?

Self-adhesive paper is a kind of self-adhesive paper, which can be directly affixed to the object after tearing off the base paper. Common self-adhesive materials can be divided into paper and film. Common paper are coated paper, thermal paper, fragile paper, embossed paper, writing paper and so on. Common films include pet, pp, pe, pvc and so on.

Also known as Post-it notes, self-adhesive labels. It is a composite material with paper, film or special material as the surface material, the back is coated with adhesive, and the bottom paper is coated with silicon protective paper. Since the surface material needs to print pictures and text, it needs to have good ink performance. According to different transportation and use environment, it is necessary to choose the adhesive with corresponding properties. Self-adhesive material suitable for product packaging materials and use environment, after printing, die-cutting, cutting or rewinding processing, finally become the self-adhesive label used in the market.

Self-adhesive is generally composed of three parts visible to the naked eye, in fact, according to the functional subdivision, self-adhesive is composed of seven parts: 1. Surface coating (changes the properties of the surface material, such as tension, color, protective layer, etc.)2. Surface material 3. Coat the bottom layer (to protect the surface material, increase opacity, increase bonding, prevent penetration)4. Adhesive (roughly classified as permanent and removable)5. Release coating (prevents adhesive from sticking to backing paper)6. Back paper (accepts release paint, protective surface material)7. Back coating/back printing (can print trademark patterns, promote anti-counterfeiting)

Common paper self-adhesive, generally can be torn, not waterproof. If you want to improve the waterproof and antifouling performance, it is necessary to carry out coating, oil and other processing processes on the surface.

The film type material is not torn, waterproof and moisture-resistant. According to the transparency size, the film label is divided into three categories: white, transparent and metal. Film can be divided into pet, pp, pe, pearlescent film and so on.
