The hottest high transparent polyethylene heat shr

High transparent polyethylene heat shrinkable label

the traditional form of outer packaging in the beverage industry is carton packaging, which has poor moisture resistance and is easy to mold; Unable to withstand extrusion, inconvenient transportation and storage; It consumes natural resources, which is not conducive to the environmental protection of no more than 4 pages, and the labor cost and equipment investment cost required for carton packaging are high. Another kind of traditional outer packaging, such as the outer packaging of bottled beer, is bundled packaging, which costs a lot of labor and is extremely unsafe, and is easy to cause bottle explosion

in view of the defects of the above two outer packaging forms, people began to use label packaging with polyethylene heat shrinkable film to replace the traditional carton packaging and strapping packaging. As a label packaging material, heat shrinkable film has unique advantages: saving forest resources, reducing costs, moisture-proof, sanitary, easy to use; The packaged goods are beautiful and save space

the heat shrinkable film label can be "body fitted" packaging, so that the goods have a distinctive appearance; As polyethylene is recognized as a non-toxic material, it is especially suitable for commodity labels in food, medicine, beverage and other industries. The high transparent polyethylene heat shrinkable label printing film is made from the high transparent polyethylene heat shrinkable film as the base material and processed with the internationally advanced flexible plate brush. It adopts a special formula to replace the conventional low-density polyethylene resin heavy packaging material to make a heat shrinkable film with high transparency, good processability and high strength. Satellite flexographic printing technology is adopted: all printing color groups share an embossing cylinder (1), which is a printing method arranged in sequence. At the same time, the metallographic polishing machine should rotate and move back and forth along the radius of the rotary table. Not only the registration accuracy is high, but also the solvent used is alcohol, which is a "green printing" that fully meets the requirements of environmental protection. It has the following good characteristics:

1 Transparency its transmittance can reach 90%, greatly improving the printing effect

2. Surface characteristic surface friction coefficient ≥ 0.4, which makes the packaging and stacking stable and convenient for transportation

3. Strength longitudinal and transverse tensile strength ≥ 24MPa, longitudinal and transverse elongation at break ≥ 700%, ensuring the weight of the contents. 4. Heat sealing property heat sealing strength ≥ 20n, so that it can meet the needs of mechanized packaging production, as the name suggests

5. The registration accuracy is high, and the registration can be easily controlled below 0.1mm

6. Solvent residue. Its solvent residue will be kept at about 5mg/m2, which is far lower than that of other printing methods. 7. Save ink consumption
