Understand PET Film And PVC Film And Their Applications
PET：
1. PET film is a packaging film with comprehensive performance. It has good transparency and gloss;
good air tightness and fragrance retention; moderate moisture resistance, and its moisture permeability decreases at low temperatures. PET film has excellent mechanical properties, and its toughness is the best among all thermoplastics. Its tensile strength and impact strength are much higher than those of ordinary films; it has good strength and stable dimensions, and is suitable for secondary processing such as printing and paper bags. PET film also has excellent heat resistance, cold resistance, and good chemical resistance and oil resistance. However, it is not resistant to strong alkalis; it is easy to carry static electricity, and there is no appropriate anti-static method, so attention should be paid when packaging powdery items.
PET material:
PET is often used in transparent hanging curtains in shopping malls, suitable for display windows, customized requirements, exhibitions, etc.
PVC：
The main component of PVC film is polyvinyl chloride, which is slightly yellow and translucent and shiny. The transparency is better than polyethylene and polypropylene, but worse than polystyrene. Depending on the amount of additives used, it is divided into soft and hard polyvinyl chloride. Soft products are soft and tough, and feel sticky. The hardness of hard products is higher than low-density polyethylene, but lower than polypropylene, and whitening will occur at the bends. Common products: plates, pipes, soles, toys, doors and windows, wire sheaths, stationery, etc. It is a polymer material that uses a chlorine atom to replace a hydrogen atom in polyethylene.
PVC material:
Considering the cost factor, digital inkjet printing generally uses PVC or composite PVC materials more often. At this time, we generally only need to examine the appearance. High-quality PVC films usually have a uniform and smooth surface, consistent color and no obvious color difference or deformation. PVC films with rough surfaces, defects or deformations may be of poor quality.
PVC films are widely used in the field of digital inkjet printing. The following are some of the main application scenarios:
1. Advertising imaging and inkjet printing: Digital inkjet printing technology provides the advertising industry with high-quality, bright and durable image output, whether it is outdoor billboards, light boxes or other forms of advertising materials.
2. Building decoration: Digital inkjet printing is widely used in building materials such as tiles, color peeling, wallpaper and carpets, and can achieve personalized design and customization.
3. Craft decoration printing: On accessories, gifts and other crafts, digital inkjet printing can provide exquisite patterns and details.
