Now most of the bags are made of plastic, but the plastics are also classified. Different types of plastics use different inkjet printers to produce better results. Leadjet will give you an analysis of which plastic materials use which type of printer is better.
PP: Polypropylene. It is a semi-crystalline thermoplastic plastic with high impact resistance, strong mechanical properties, resistance to various organic solvents and acid-base corrosion, and is widely used in industry. This kind of material belongs to common polymer materials. The UV ultraviolet laser printer is better. The UV laser printer is cold-processed. It can change the molecular structure of the surface of the material through the purple light of 355 nm wavelength, leaving a permanent mark and greener. Environmentally friendly and efficient.
OPP: oriented polypropylene. The white point is a plastic bag, characterized by easy burning and softness. It is recommended to use a thermal transfer printer to print. The thermal transfer printer can achieve high-speed coding, and the effect is beautiful. It is very suitable for high-efficiency printing of plastic bags. In particular, it can be equipped with some rewinding and unwinding machines to achieve high-speed online assignment. The other is that the resolution is relatively high. If the variable two-dimensional code is printed, there will be a very good scanning recognition rate.
PET: Polyterephthalic plastic. PET is the abbreviation of English Polyethylene terephthalate, referred to as PET or PETE. Common in mineral water bottles, carbonated beverage bottles, etc., has now developed into the current beer bottles, edible oil bottles, condiment bottles. Pharmaceutical products, cosmetic bottles, etc., suitable for the coding equipment are small character inkjet printers and ultraviolet laser printers, widely used for small character inkjet printers.
ABS: acrylonitrile-butadiene-styrene copolymer. ABS resin is one of the five synthetic resins with impact resistance, heat resistance, low temperature resistance and chemical resistance. The electrical performance is excellent, and it has the characteristics of suitable processing, stable product size, good surface gloss, etc. It is easy to be coated and colored, and can also be subjected to secondary processing such as surface metallization, electroplating, welding, hot pressing and bonding. Widely used in machinery, automotive, electronic appliances, instrumentation, textile and construction industries, it is a very versatile thermoplastic engineering plastic. This kind of material uses laser jet printer to code more, because the application industry is different, so what type of laser printer is needed to carry out on-site proofing, compare the effect to judge.
PVC: Polyvinyl chloride. It is a white powder with a fixed structure, the degree of branching is small, the relative density is about 1.4, the glass transition temperature is 77---90 °C, and the decomposition starts at about 170 °C. The stability to light and heat is poor, above 100 °C or over a long period of time. When exposed to sunlight, it will decompose to produce hydrogen chloride, and further autocatalyze decomposition, causing discoloration, and physical and mechanical properties are also rapidly declining. In practical applications, stabilizers must be added to improve the stability to heat and light.
PVC material is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wire and cable, packaging film, bottles, foam materials, sealing materials, fibers and other aspects. These industries use a large number of inkjet printers. When selecting a printer to print, it is still necessary to perform proofing analysis on the product and select a better inkjet printer.
