- plastic bag
5.1 introduction
Plastic bags are bags made of plastic (commonly used plastics are polypropylene, polyester, nylon, etc.) as the main raw material, which are essential for people's daily life and are often used to contain other items. Because of its cheap, very light weight, large capacity, easy to organize the advantages of being widely used
5.2 Types
5.2.1. Polyethylene (PE for short)
Polyethylene is a high molecular organic compound formed by polymerization of ethylene. Polyethylene is recognized worldwide as the best material for food contact. It is non-toxic, tasteless and odorless, and meets the hygienic standards for food packaging. Polyethylene film, light and transparent, with moisture, oxygen, acid, alkali, airtightness in general, excellent heat sealing properties. Known as the "flower of plastic" reputation. It is the most used plastic bag printing, the most important material.
5.2.2.PVC--Polyvinyl Chloride
Polyvinyl chloride abbreviation PVC, molecular formula (CH2-CH2) n, is the most important class of vinyl polymers, is currently the world's second largest plastic varieties after polyethylene. In the domestic production of plastics in the first place. In the printing industry, PVC color calendered film and transparent varnish film are often used to make books, folders, tickets and other covers of the packaging and decoration.
5.2.3.Shrinkfilm--Shrinkfilm
Shrinkfilm is a thermoplastic film that is stretched and oriented during the production process, and shrinks when treated with hot air or infrared light during use. After heat treatment, the film is tightly wrapped around the packaged goods, and the shrinkage force reaches its maximum value during the cooling phase and can be preserved for a long period of time.
5.2.4. LDPE - Low Density Polyethylene
Low-density polyethylene, referred to as LDPE is the largest variety of plastic packaging printing industry in various countries. Specific gravity of 0.92 ~ 0.93, can float in water. Low crystallinity (60%), in the pressure 1000 ~ 3000kg / cm3 for the body polymerization, so also known as high-pressure polyethylene. At 23ºC, the density is about 0.92. Poor calendering and molding, suitable for blow molding method to process into tubular film. Suitable for food packaging, fiber products packaging, household goods packaging.
5.2.5.HDPE--High Density Polyethylene
High-density polyethylene, referred to as HDPE, the density of 0.941 ~ 0.965g / cm3. With low-pressure polymerization, so also known as low-pressure polyethylene. Milky white color, indicating poor luster. Processing film available blow molding method and T die extrusion process. Heat-resistant and steam-resistant, cold-resistant and freezing-resistant, moisture-proof, gas-proof, good isolation performance, and not easy to break, the strength of LDPE two times. Extremely easy to open. Paper-like strong, known as "paper-like plastic film".
5.2.6.BOPP - Biaxially oriented polypropylene film
Biaxially oriented polypropylene film, also known as biaxially oriented polypropylene film, English abbreviation code BOPP, which is characterized by stretching molecular orientation, mechanical strength, folding strength, gas density, moisture barrier better than ordinary plastic film. Compared with cellophane in terms of unit area, the unit price is lower than cellophane. Because of the transparency of this film is very good, after printing the reproduction of the color is exceptionally bright and beautiful, is an important substrate for plastic composite flexible packaging.
5.3 Use application
A. Food packaging: pastry, candy, fried food, cookies, milk powder, salt, tea and so on;
B. Fiber products packaging: shirts, clothing, needle cotton products, chemical fiber products;
C. Daily chemical products packaging.
