New member of the tag family - shrink labels

The traditional packaging form of the beverage industry is carton packaging. The carton is poor in moisture resistance, and the packaging is easy to mold. It is inconvenient to transport and store after being squeezed. It consumes natural resources and is not conducive to environmental protection. The labor costs and equipment investment costs for carton packaging are also Both are higher. Another type of traditional outer packaging, such as bottled beer, is packaged in bundles. This type of packaging is labor-intensive and extremely unsafe, and can easily cause bottle explosions.

For these two types of packaging defects, people began to use polyethylene heat shrinkable film label packaging to replace the traditional carton packaging and packaging. The heat shrinkable film has unique advantages as a label packaging material: saving forest resources, reducing costs, moisture protection, hygiene, and convenience of use; the packaged goods are beautiful and space-saving.

The heat-shrinkable film label can be “fitted with” packaging, so that the goods have a distinctive appearance; because polyethylene is recognized as non-toxic materials, it is particularly suitable for food labels, pharmaceuticals, beverages and other industries. High transparent polyethylene heat shrinkable label printing film is based on high transparent polyethylene heat shrinkable film as substrate, and the film is formed by international advanced flexo plate brush processing. Special formula is used to replace conventional low density polyethylene resin. Heavy packaging material, made of high transparency, good processing performance, high strength heat shrinkable film.

The use of satellite flexographic printing technology; all printing groups share one impression cylinder, one printing sequence in a sequence, not only high accuracy of registration, but also solvents used are alcohol, is fully in line with environmental protection requirements " Green printing." It has the following good features:

1. Transparency: The light transmittance can reach 90%, greatly improving the printing effect.

2, the surface characteristics: the surface friction coefficient ≥ 0.4, so that the stacking stable, convenient transportation.

3, strength: vertical and horizontal tensile strength ≥ 24MPa, longitudinal and transverse elongation at break ≥ 700%, to ensure that the contents of the weight.

4, heat sealing: heat seal strength ≥ 20N, so that it can meet the needs of mechanized packaging production.

5, high registration accuracy, you can easily control the layout below 0.1mm.

6, the residual solvent is low, the residual solvent will remain at about 5mg/m2, much lower than other printing methods.

7, consumption of ink province.

The above excellent characteristics have determined that the label of high transparent polyethylene heat shrinkable printed film is the development trend of the label industry, and its market prospect is very broad.
