What units use stretch film and which industries are stretch films used in?

1. Packaging costs can be reduced.
When packaging the same volume of goods, the amount of film used can be reduced by 1/3 compared with the shrink film. Commercially available shrink film thickness is about 0.04 ~ 0.05mm. The film after shrink packaging is about 0.05-0.06mm; the thickness of the commercially available stretch film is 0.02-0.03mm. The thickness of the film after packaging is about 0.015-0.025mm.

2. Compared with the use of ordinary packaging film, when carrying out bundling and packaging operations. Can eliminate a lot of accessories (such as straps, strapping rope, corner cardboard, buckles, etc.). And can simplify packaging equipment, save a lot of energy.

3. Has better safety performance. During packaging operations. Heating devices such as hot air blower and oven are not required. Especially for the warehousing and packaging industry. It can avoid the use of electrical facilities in the warehouse and improve the safety factor of the warehouse.




4. The wrapping film can tightly wrap the goods as a whole, reducing the damage, collapse and loose packing of the goods during storage and transportation. One ton of palletized goods. After wrapping and packaging. The maximum tilt angle can reach 45.

5. The goods can be waterproof and dustproof by winding packaging. High transparency. The variety of packaged goods can be easily distinguished. The wrapping film is non-toxic, odorless and tasteless. It can meet the requirements of food hygiene performance.
 
Through the above characteristics, many enterprises can use it, such as: machinery factory, food factory, canning factory for tinplate, food canning factory, glass bottle factory, winery and so on.

The characteristic of the film is shrinkage, which can strengthen and protect many easy-to-touch and fragile things, because most of these products cannot be used with ropes or packing tapes.

Stretch film, also known as stretch film and heat shrinkable film, was the first in China to use PVC as the base material, DOA as the plasticizer and self-adhesive effect to produce PVC stretch film. Due to environmental problems, high cost (large relative PE ratio, less unit packaging area), poor stretchability and other reasons, when the domestic production of PE stretch film began in 1994 to 1995, it was gradually eliminated. PE stretch film was first used EVA as self-adhesive material, but its cost is high and tasteful, and later developed with PIB, VLDPE as self-adhesive material, the base material is now mainly LLDPE, including C4, C6, C8 and metallocene PE (MPE).
