Introduction to self-adhesive label materials

self adhesive label materials according to the economic operation of China's extruder industry, there have been several positive signal materials, which are divided into paper self-adhesive labels and film self-adhesive labels. Paper labels are divided into: heat transfer paper, coated paper, mirror coated paper, writing paper, west card paper, kraft paper, etc. These are familiar to people. With the acceleration of industrialization and the enhancement of people's awareness of environmental protection, Thin film PEEK composites can reduce the weight of aircraft. Self adhesive materials have sprung up. Xiangrun electronic technology focuses on discussing thin film labels with you here

common film materials include PE, PP, pet, PVC, PP and PE mixture, synthetic paper, etc. different materials have different characteristics and application fields, and most film materials can be processed into multicolor (polyethylene): good flexibility, extrusion resistance, poor tensile elongation, white and transparent colors, can be metallized. Because PE has good softness, it is often used on bottles that need frequent extrusion and are easy to deform. However, PE material is too soft, and the pressure testing machine needs to increase the stiffness by increasing the thickness to detect large compressive strength. The thickness of 80 ~ 100 m is the most common, and it is often used as a large-area labeling material

2.pp (polypropylene): biaxial tensile treatment with machine, also known as BOPP, has high hardness, good tensile elongation, good light transmittance, excellent durability, but the temperature resistance is general, and the transparent material has excellent transparency. PP material is applied to the bottle body with hard surface and will not be extruded. The use of grazin paper or pet paper in the market with PP surface materials is to take into account the transparency requirements of different levels

3. Pet (polyester): excellent high temperature resistance, durability and tensile elongation. In addition, it has good chemical corrosion resistance, high stiffness, a variety of colors, can be metallized, and the transparency of transparent materials is excellent. The material does not deform when stretched, so it is difficult to tear it, and it will make the sound of metal friction when shaking. It is widely used in electrical, electric and mechanical equipment, which can reflect good texture and strength

4. PVC (polyvinyl chloride): there are two kinds of soft and hard, with good durability, tear resistance, softness and chemical corrosion resistance. It is widely used in electronics, machinery, batteries and outdoor stickers. However, the temperature resistance and tensile elongation are general, and there will be a certain degree of shrinkage affected by temperature. It is easy to tear when stretching. Limited by environmental protection, it is less and less used indoors at present

5. Mixture of PP and PE (polyolefin): it has high tensile strength and tear resistance, low light transmittance, soft material and extrusion resistance after uniaxial tensile treatment by machine. The material can stretch in one direction to form a straight line, and behave very hard in the other direction. This kind of material integrates softness and stiffness. It has good stiffness in the direction of the machine and softness in the other direction. It can be marked smoothly when labeling and has good extrusion resistance after labeling. It is widely used in glasses care solution and daily chemical products

6. Synthetic paper (a kind of PP material): it looks like paper, matte white, after biaxial stretching treatment, the material is tough and has good extrusion resistance. At the same time, it has good heat transfer printing performance and hard material texture, which is suitable for flat or hard surfaces. It is widely used in electronic components and daily chemical products
