Self-adhesive label material knowledge introduction

Self-adhesive label materials are divided into two types: paper self-adhesive labels and film self-adhesive labels. The paper labels are divided into: thermal transfer paper, coated paper, mirror coated paper, writing paper, sika paper, kraft paper, etc. And so on, these are people familiar with, with the acceleration of industrialization and people's awareness of environmental protection, film adhesive material suddenly rises, enjoy the benefits of electronic technology here and focus on discussing film labels.

The common film materials are PE, PP, PET, PVC, PP and PE blends, synthetic paper, etc. Different materials have different characteristics and application fields, and most of the film materials can be processed into multicolors.

1. PE (polyethylene): It is soft, resistant to crushing, poor in stretch resistance, white and transparent, and can be metalized. Due to its good softness, PE is often used on bottles that are often squeezed and easily deformed. However, the PE material is too soft and needs to increase the stiffness by increasing the thickness. The thickness of 80 to 100 μm is the most common, and it is often used as a large-area labeling material.

2. PP (polypropylene): Biaxially oriented machine, also known as BOPP, has high hardness, good tensile resistance, good opacity, and excellent durability, but it is generally resistant to heat and transparent materials have excellent transparency. . The PP material is applied to a bottle that has a hard surface and cannot be squeezed. In the market, the use of Glassine paper or PET liner to match PP face material is taking into account different levels of transparency requirements.

3. PET (polyester): excellent high temperature resistance, durability and tensile resistance, good chemical resistance, high stiffness, a variety of colors, can be metallized, transparency of the transparent material is excellent. The material is not deformed by stretching, it is difficult to tear, and metal friction sounds when it is shaken. Widely used in electrical appliances, electric and mechanical equipment, can reflect a very good texture and strength.

4. PVC (polyvinyl chloride): It has two kinds of soft and hard, durability, tear resistance, flexibility, good chemical resistance, and is widely used in electronic, mechanical, battery, and outdoor applications. However, the temperature resistance and the tensile resistance are normal, and a certain degree of shrinkage occurs due to the temperature. It is easy to tear when stretched. Due to environmental restrictions, there are fewer and fewer indoor applications.

5. Mixtures of PP and PE (polyolefins): Uniaxially stretched with a machine, has a high tensile strength and tear resistance, low opacity, soft material, and extrusion resistance. The material can be stretched to form a straight line in one direction and hard in the other direction. This kind of material combines softness and stiffness in one, has good stiffness in the machine direction, good softness in the other direction, smooth labeling at the time of labeling, and good crush resistance after labeling. Widely used in eye care solution and daily chemical products.

6. Synthetic paper (a kind of PP material): looks like paper, matt white, after biaxial stretching, tough material, good crush resistance. At the same time with good thermal transfer printing performance, hard texture, suitable for flat or hard surface. It is widely used in electronic components and daily chemical products.
