What materials are common printed matters made of in daily life?

Self-adhesive printing, simply put, refers to the process of transferring ink and other substances onto the surface of a substrate that has a pre-coated adhesive layer on its back, under certain pressure. So, what materials are used for self-adhesive printing?


Self-adhesive printing, simply put, refers to the process of transferring ink and other substances to the surface of a substrate with a pre-coated adhesive layer on the back of the printing plate under certain pressure. So, what materials are used for self-adhesive printing?

There are many materials for self-adhesive printing, generally including the following:


Coated paper: Coated paper is made from painted base paper after coating and decorative treatment, with a smooth and delicate surface, making it one of the most widely used materials. It is mainly used for information labels in medicine, food, edible oil, alcohol, electrical appliances, cultural goods, etc.

Writing paper: Also known as rough mold paper, it is a self-adhesive label with a rough surface that can be printed by laser printers, inkjet printers, or barcode label machines. It is generally used for product price tags, information labels, barcode printing labels, material labels, shipping labels, etc.

Aluminum foil paper: Suitable for high-end information labels in medicine, food, and cultural goods.

Thermal paper: Thermal paper is a type of paper processed from coated paper. Its manufacturing principle involves coating a layer of "thermal paint" (thermochromic layer) on high-quality base paper. It is suitable for price tags and other information labels, as well as other retail uses.

Fragile paper: Its characteristic is that the label paper breaks immediately after peeling off the self-adhesive seal and cannot be reused; it is widely used for goods such as mobile phones, telephones, computer accessories, automotive electronics, alcohol, medicines, food, cosmetics, performance tickets, etc.

Laser film: Anti-counterfeiting labels are produced using laser color holography and forming imitation technology. They can display enterprise information, logos, trademarks, and other identifiers on their appearance, and can also feature other special images. It is an information label suitable for cultural goods and decoration.

PP (Polypropylene): Available in bright white, matte white, bright silver, and transparent. It has the characteristics of water and oil resistance. Widely used in daily chemical products and cosmetics.

PE (Polyethylene): Available in bright white, matte white, bright silver, and transparent. It is soft, has good extrusion resistance, and is water and oil resistant. Due to the softness of PE self-adhesive materials, they are often used for bottles that require frequent squeezing and are prone to deformation. Information labels for bathroom products, cosmetics, and other extruded packaging.

PET (Polyethylene terephthalate): PET self-adhesive material is a high molecular material with good hardness and brittleness, and is naturally degradable. It is generally divided into: light silver PET, matte silver PET, and brushed silver PET, widely used in various special occasions, such as mobile phone batteries, computer monitors, air conditioner compressors, etc.

PVC (Polyvinyl chloride): Also a high molecular material, common colors include matte white and pearl white. PVC's performance is close to PET; it has better flexibility than PET and a soft feel, but PVC's degradability is poor, negatively impacting environmental protection. It is often used in occasions such as jewelry, watches, the electronics industry, and the metal industry.
