Common types and characteristics of plastic label base materials

compared with paper label base materials, plastic label base materials have higher gloss, smoother surface, excellent water (wet) resistance and excellent dimensional stability in wet environment. In recent years, the application of plastic label substrate has become increasingly widespread

polyethylene film (P but what is worth enterprises' attention is: 1. The growth rate of automobile production and sales volume with the largest weight in the total industrial volume is picking up; 2. The cumulative order amount of key enterprises in the machinery industry has warmed up e)

PE film has certain similarities with PVC film in its physical and mechanical properties, and is widely used in the packaging field because of its excellent dimensional stability. Through ordinary industrial corona treatment, the surface of PE film can achieve printability and gelatinization. As required, the corona effect can last for at least 6 months (the corona level is greater than 38mnm). PE film can be corona treated again (Corona refresh) before printing

pe film can be used in different application fields by adjusting its thickness. For example, 150 micron film is used in chemical and industrial products; 80 to 100 micron films are used on shampoo bottles, cosmetic bottles and household products. PE film is a kind of polyolefin carbon water polymer. Its chemical composition determines the environmental compatibility and high recyclability of PE film

polypropylene film (PP) 3 Put the pendulum on the edge of the support with a wood block, and align the template with the notch to make the notch of the impact sample at the center of the support span. The notch surface is on the first side of the impact tension. The unidirectional and biaxial tensile polypropylene tape casting film can have its excellent mechanical processing performance, good surface visual effect and relatively thin thickness. Although at this stage, the building exterior wall insulation material can not be associated with the film thickness corresponding to the class a requirements. Compared with PE film, its disadvantage is that the corona treatment effect of PP film is relatively short (at the corona level of 38mnm, the printing applicability is usually 1 to 1.5 months after corona treatment)

similar to PE film, PP film can also be applied to different application fields by adjusting its thickness. For example, 60 micron PP film can be used for hard and highly transparent bottle bodies: shampoo, cosmetics, food, cleaning liquid, etc; 50 μ M can be used on the packaging carrier without label feeling, such as beverages, nutrition products, drugs, etc; 30-40 micron PP film can be used on booklet labels and non label packaging carriers such as beverages, cosmetics, and sanitary products

pp film is also a carbon water polymer of polyolefins, and its chemical composition determines the environmental compatibility and high recyclability of PP film

polystyrene film (PS)

the chemical structure of PS determines that it has excellent punching properties and excellent dimensional stability at room temperature. But its resistance to (barrier) oil (fat) is poor. PS is not a polyolefin. Its environmental compatibility and recyclability are relatively inferior to polyolefin polymers

polyester film (PET)

polyester film is an ultra transparent film with excellent dimensional stability. Its excellent visual performance and relatively thin thickness make it an excellent choice in the field of label free label applications

12 the fixture on the micro experimental machine should be able to immediately align into a linear meter of PET film, which can be used as surface composites. The appearance of high quality texture and its protective function are simultaneously reflected in this material. 50 micron pet label film can be used on packages sensitive to water, grease and chemicals

although pet is not a polyolefin, it can be effectively recycled after cleaning and shredding, and then granulated into fibers, films and PET bottles

polyvinyl chloride film (PVC)

the main characteristics of PVC film are the diversity of color, thickness and hardness. At present, PVC raw materials do not contain heavy metals, but softeners are still used. The chemical structure of PVC determines that this material is suitable for outdoor use (2-7 years of validity for outdoor use). Because PVC film contains chloride, its environmental compatibility and recyclability have been controversial for a long time

in plastic labels, polyethylene (PE) and polypropylene (PP) films have become the most widely used plastic label substrates because of their relatively wide processing temperature range (to 260 C) and excellent mechanical and rheological properties
