The Role Of Shrink Packaging

shrink wrapping is a packaging technique in which an item (or inner package) is wrapped in shrink film and then the film is properly
 heat treated to it and bring the film closer to the item (or inner package).
Shrink-wrapping function

① Shrink wrapping can pack special shaped products that are difficult to pack by general methods, such as vegetables, fruits, fish, etc.
② The film itself is cushioned and tough, which can prevent damage to the product due to vibration and shock during transportation.

③The shrink film of packaging is usually transparent. After heat itage, it will adhere to the product and show the appearance of the product. Because the itage is more uniform. And the material has a certain toughness, and the corners are not easy to tear.

④ Good sealing, moisture-proof, shrink stain-proof and rust-proof effect, easy to store in the open air and save warehouse space.

⑤ It is convenient to pack various scattered products together, and sometimes the box can be omitted with the help of shallow tray.
⑥Packaging technology and equipment are simple and universal, easy to realize mechanization, save manpower and packaging costs, and can partially replace corrugated cartons and wooden boxes.

(7) On-site packaging method can be used for packaging of large products, such as racing boats and automobiles. The process and equipment are very simple.
⑧It can extend the shelf life of food and facilitate storage.

Shrink Packaging Materials

Shrink films are polyethylene films that have been specially stretched and cooled.
The film will sharply both horizontally and vertically as a result of residual shrinkage stresses created during directional stretching of the film, which will be removed after a certain amount of heating.

At the same time, the film thickness increases and the itage rate is usually 30% to 70%.
This biodegradable film not only has the functions and properties of traditional plastics, but also decomposes and degrades in the natural environment

environment through the action of microorganisms in soil and water or the action of the sun’s ultraviolet light after its service life, and eventually re-enter the ecological environment in the form of reduction and return to nature.

Domestic varieties developed include photodegradation, photobiodegradation and photo-oxidative biodegradation.

solution, high starch content type biodegradation, high calcium carbonate filled photo-oxidative degradation, and total biodegradation. The most commonly used are edible and water-soluble membranes.
