The use of the five big plastic label performance

Five plastic tags using performance of plastic label profile has high gloss, smooth surface, excellent resistance to water ( Wet) Sex and excellent dimensional stability under humid environment, the application of plastic label material is becoming more and more widely in recent years. 1 the kinds of plastic label and performance. Polyethylene film ( PE） On its physical and mechanical properties of PE film and PVC film has a certain similarity, more because of its excellent dimensional stability and is widely used in packaging field. Through ordinary industrial corona treatment can make the surface of PE film to print and glue can be. According to the need, corona effect sustainable (at least 6 months Corona levels greater than 38 MNM) 。 PE film can make corona processing (again before printing Corona refresh) 。 PE film can be adjusted through the thickness to make for different application fields. Such as 150 micron film for chemical and industrial products; From 80 to 100 micron film for shampoo bottle, cosmetic bottle, and articles for daily use. PE film is a kind of polyolefins carbohydrate polymers, its chemical composition determines the environmental compatibility of the PE film and high degree of recyclability. 2. Polypropylene film ( PP) Unidirectional tensile and the bidirectional tensile polypropylene stretch film can be excellent machining performance, the surface of the good visual effect, and relatively thin film thickness. Compared with PE film, its drawback is that PP film corona treatment effect is relatively short ( In the level of the 38 MNM corona, usually one to one and half months after corona treatment printing adaptability) 。 PP and PE film, PP film can also be through the adjustment of its thickness is suitable for different application fields. Such as 60 micron PP film can be used in rigid, high transparent bottles: shampoo, cosmetics, food, cleaning fluid, etc. 50 micrometers can be used for drinks, such as nutrition, medicine & other No labels & throughout; On the packing of the carrier; 30 to 40 micron PP film can be used in the booklet label and beverages, cosmetics, and toiletries & other No labels & throughout; On the packing of the carrier. PP film and polyolefins carbohydrate polymers, its chemical composition determines the environmental compatibility of PP film and high degree of recyclability. 3. Polystyrene film ( PS） PS chemical structure determines it at room temperature with excellent cutting and excellent dimensional stability. But its resistance ( Cut off) Oil ( Fat) The gender is poorer. PS are not of polyolefins. Its environmental compatibility and recyclability than polyolefin polymers relatively inferior. 4. Polyester film ( PET) Polyester film is a kind of super transparent film and excellent dimensional stability. Its excellent visual performance and make it a relatively thin thickness & other; No labels are & throughout; Label a good choice in the field of application. 12 micron PET film can be used for surface composites. The appearance of the high quality sense and its protection function on the material to get at the same time. 50 microns PET label film can be used for sensitive to water, grease and chemicals on the packaging. The PET does not belong to polyolefins, but it can be effective after cleaning and chopped the recycled and granulation and fiber, film and PET bottles. 5. Polyvinyl chloride (PVC) film ( PVC) The main characteristics of PVC film is the diversity of color, thickness and hardness. The PVC raw materials do not contain heavy metals, but still use the softener. PVC chemical structure determines the material suitable for outdoor use ( The validity of 2 to 7 years of outdoor use) 。 PVC film for containing chloride, its environmental compatibility and recyclability controversial for a long time. In the five plastic tags, polyethylene ( PE) And polypropylene ( PP) Thin film because of its relatively wide processing temperature range ( To 260 & deg; C) And excellent mechanical and rheological properties has become the most widely used plastic label material.
