Different sectors Label Have their own characteristics and use of industry requirements, daily chemical industries (such as shampoo and shower gel) to require label printing fine, gives a sense of beauty, attract customers attention; and electronic components for a specific production process, often require labeling face materials and adhesives to meet the harsh environment, acid and alkali resistance, a moderate level of UV, label printing and print the content itself remains clear and complete guidance to consumers to use or play a warning. Electronic products often require the label to be affixed, and the life of products for the same period, we label as the durability of this type of label, the label surface materials require good weather resistance and tenacity, adhesive requires higher bond strength and durability. Durable labeling applications industries are: industrial electronics, auto, cable marking, electric tools. Here we get to how to choose a label for the durability of your application. Select process
first step is to identify the requirements for your use of adhesives durability. Adhesives selection should include consideration of the following indicators: being affixed substrate surface energy, substrate material, substrate shape, temperature, temperature, and labeling, and such as outdoor use, contact with chemical substances such as environmental factors.
Viscoelastic properties of pressure sensitive because of the special, you can make it in a slow and proper under the action of external pressure on the viscous flow to achieve the sticky surface and being in close contact. This close contact but only enough to generate sufficient adhesion. PSA must also be posted on the good surface wetting, so that it was affixed to the free surface molecules close to the molecular interaction between the distance, so as to have sufficient adhesion. High surface energy of the substrate surface can be very easy for adhesives, wetting, so as to achieve a higher viscosity. The low surface energy substrate wetting is not easy to glue. High surface energy substrates including aluminum, copper, glass, gold, lead, stainless steel and other metals, the low surface energy substrates, including nylon, epoxy resin, PC, PET, PVC, ABS, PS and other plastics. Durability of adhesives can be divided according to the composition of rubber and acrylic are two basic types, according to water-soluble coating can be divided into two types and the solvent. Durability of adhesives can be divided according to the composition of rubber and acrylic are two basic types, according to coating methods can be divided into two kinds of water-soluble type and solvent. Solvent-based rubber-based adhesives as good liquidity and the initial viscosity, very low surface energy substrate for the labeling, as well as powder coating paint surface and surface texture. Solvent-based acrylic adhesive with each other by the cross-linked acrylic polymer composition, have excellent temperature and chemical resistance for hard paste of the low surface energy substrates, a short time can be re-posted, with excellent chemical resistance, resistance to ultraviolet radiation can be a long time, can be recommended for outdoors.
Many customers with PET labels such as ABS plastic, and after temperature and humidity changes, the label drum surface from the phenomenon of blistering occurs. This is because the ABS material in the heat and volatile gases out of the result can not be excluded. Farson textured rubber products through a special textured plastic surface treatment, forming mesh Fissure plastic surface, can be affixed with the label substrate to maintain patency between the air and the outside world, so that label was affixed to the surface and not between bubbles to ensure the label surface roughness. Label applied to a large area, rough surface, labeling and storage in the course of the temperature difference between environment.
Select step process to select a suitable material commonly used in the durability of the surface film into polyester film, PVC film, synthetic paper, polyolefin films, polyimide films and other special films, different thin film materials have different specifications and physical and chemical properties.
1. PET film, which is most widely used PET film has strong tensile strength and tear strength, excellent high temperature properties can be called by the processing of high transparency, opaque, and metallized films. Surface treatment and surface coating, it can adapt to all kinds of printing and bar code printing, have a good automatic labeling capabilities. Common thickness of 25 microns and 50 microns.
2. PVC film, also known as PVC film, in accordance with the production process can be divided into two kinds of casting and rolling type. Soft PVC low intensity, temperature and abilities, poor tear resistance, good flexibility, shrinkage and opacity, good processing characteristics and labeling performance, long-term outdoor use, has an excellent resistance to chemical corrosion, can be processed into a variety of colors and light, matte and metal processing film. Because soft PVC, to increase the firm in the market generally a thickness of 50 microns to 100 microns. Law firm of PVC surface materials Mori for improving the performance of products designed for labeling.
