Shrink wraps are made up of polymer plastic which tightly covers any object on application of heat. A shrink machine is used to apply heat to these wraps. These are light in weight and can be used to wrap any material.The heavier counterpart of these wraps is used for industrial purposes. They are used to cover large equipment, large construction scaffoldings such as those used in the construction of bridges and buildings, helicopters and other big vehicles. They are also used for storage purposes and other business operations. These are highly versatile materials which have wide range of applications. Their use for a variety of purposes makes them highly popular.
Use in natural disasters
They have high use during times of natural calamities and disasters during which they are used to remove hazardous material.
Any item is wrapped using these films using a roll designed for shrink wrapping. Once the film surrounds the object, a heat gun, oven or a shrink tunnel is used to shrink the film tightly around the object.
Heat Gun – A heat gun is a device which emanates heat. This heat is in the form of stream of hot air. The device itself resembles a hair dryer and operates at high temperatures.
Oven – It is basically a thermally insulated chamber. An oven is similar to that used at your home for the purpose of heating, baking or drying. It works on the same principles on which your home oven works.
Shrink Tunnel – A shrink tunnel is a heated tunnel mounted over or around a conveyor belt. The film is then passed through to create the intended result.
Shrink wraps are used to shrink in one (unidirectional) or two (bidirectional) directions. While being manufactured, these films are heated and then cooled to achieve a stretched position. They remain so until they are applied to an item and reheated. This way, the film shrinks back to its original form and covers the object tightly.
These films add quality to your products. They enhance the value of your products and make them attractive to eyes. Apart from being highly useful, they give a great look to any product and make them even more valuable. Moreover, you can use the shrink wrap for creating tamper proof packing to items like CD’s, DVD’s, stationary, games and computer software.
Meanwhile, technology continues to evolve and more varieties of shrink films hit the market. They are getting better in terms of shrink, the ability to seal, optics, toughness, and slip. All these have made them the most sought after packing material across industrial sectors. They are contributing to a number of areas including production, distribution and even construction.
