China's first generation of high transparent polyethylene shrink film developed successfully

Shanghai Ziquan Label Co., Ltd. has recently successfully developed the first generation of high transparent polyethylene shrink film printing film in China.

The traditional packaging form of the beverage industry is carton packaging. Although there are many advantages, the moisture resistance of the carton is poor. The packaging is easy to mold, cannot withstand squeezing, is inconvenient to transport and store, and consumes natural resources, which is not conducive to environmental protection. The labor costs and equipment investment costs for carton packaging are also high. Another type of traditional outer packaging, such as bottled beer, often uses the outer packaging in the form of a strapping package, which is expensive and unsafe. It is easy to cause explosions. With the development of economy and high technology, the products are changing with each passing day. Outsourcing of products has higher requirements. For the two types of packaging defects. People began to use polyethylene heat shrink film packaging instead of traditional carton packaging and packaging. Heat shrinkable film has unique advantages as a packaging material:

1. Promoting the sales of packaging in aggregate form can greatly increase sales, from a single bottle (can) sales unit to a collective
2. Reduce packaging costs. Reduce cost by 20 to 70% compared to carton packaging;
3. Easy to use and carry;
4. The goods are beautiful and the goods price effect is good. Shrink-wrapped packaging, such as goods, can be tailored to "packages" that give goods a distinctive appearance.
5. Product storage and transportation are safe. Selection of packaging has the characteristics of moisture-proof, hygiene and safety. In the unlikely event of a leaky tank bottle, the tightly wrapped membrane can protect other aggregates from damage;
6. In line with environmental protection requirements, it not only saves forest resources, but also the non-poisonous materials that Polythene Inc. believes are particularly suitable for the packaging of food, medicine, beverage and other industries.

The high transparent polyethylene heat shrinkable printing film developed by the company is based on a highly transparent polyethylene heat shrinkable film as a base material, and is manufactured by internationally advanced flexographic printing processing. The film production uses a special formula that replaces the conventional low density polyethylene resin. Made of high transparency, good processing performance, high strength heat shrinkable film. If using the flexile technology of satellite type, it is possible to share one imprinting liquid cartridge for all printing color groups. The printing methods are arranged one by one in the order above. The accuracy of the printing is high, and the solvent used is alcohol solvent. . It is the green printing that meets the environmental protection requirements.” It has the following good features.

1. Thin pupil transparency, its light transmittance can reach 90%, greatly improving the printing effect using the India way. The fork can avoid the film surface printing pattern to save the wear 2. Film surface characteristics, surface friction coefficient ≥ 0.4. To make stacking stable and convenient to transport The strength of the film, longitudinal tensile strength is greater than ≥ 24Mpa + vertical and horizontal elongation at break ≥ 700%, to ensure the weight of the contents.
4. Film heat sealability. Heat seal strength ≥20N. To meet the needs of mechanized packaging production Register accuracy is high. It is easy to control the layout below 0.1mm.
6. The residual solvent level is low, and will remain at 5 mg/day, which is far lower than other printing methods.

The above excellent characteristics determine that the high transparent polyethylene heat shrinkable printed film is a development trend of the packaging industry, and its market prospect is very broad. Many domestic top suppliers have come to Ziquan Label Company to request the adoption of this new material. Pack your own product. (Yu Weimin Bi Jiayu)
