Shrink wrap for "big items" such as boats and equipment can be as wide as 40' and up to 10 mils thick. Application (shrinking) is usually done with a propane fired heat tool/gun. Smaller items can be protected with lower gage films and shrinking is easily handled with smaller electric heat guns. In some cases, securing large, unsupported areas may require tapes or straps in addition to heat shrinking
The technique or procedure used to attach shrink wrap to an item or product is determined by a number of factors. The size and shape of the item/product. If shipping, how far and under what conditions. If being stored, how long will the item/product be stored and will it be stored inside or out.
Selecting the correct film for a specific application is important. For example, a boat being transported from Florida to Seattle during the winter needs a wrap tough enough to withstand winter elements and highway speeds. On the other hand, a boat stored outside requires protection from the weather and ultra violet rays.
Therefore, how the shrink wrap is manufactured plays a critical role in selecting the correct film for the job at hand.
UVI (ultraviolet inhibitors) protects the shrink film against deterioration from the sun. For example, storage in Florida or Arizona requires a higher UVI rating than in the northern states.
For transporting, the wrap must have elasticity and be have puncture resistance. The EVA (ethyl vinyl acetate) content is a measurement of the film's durability.
Color is also important. White shrink film reflects the sun, keeps the interior cooler and is used mostly in the south. White film temps will also have a tendency to fluctuate better with surrounding temperatures. Dark color films can absorb the rays from the sun, keeps the interior warmer and is used in colder climates. One should be careful when using the darker films as there can be situations of large temperature swings, from hot to cold, possibly creating moisture under the film. Clear wrap is used mostly for interior storage, interior shipping ad product display.
There are 3 key elements that determine the effectiveness of a shrink wrap cover
1.the selection and quality of the shrink wrap material.
2.the technique or procedure used to apply and shrink the wrap.
3. the capability of the person performing the wrapping process.
Shrink wrap is a low density polyethylene film made from fractional melt resin and other additives. The shrink films that we stock and distribute are available in a variety of widths, lengths, thicknesses and colors to meet a variety of needs.
In the marine industry, boat builders and dealers use shrink wrap to protect boats during transport and storage. Manufacturers also depend on shrink wrap to protect products during shipping and storage. On job sites, contractors use shrink wrap for temporary material protection, work place shelters and environmental containment.
As a protective covering, shrink wrap applications are limited only by the imagination. It's not only easy to use, but almost any shape or size of product can be wrapped and protected.
