Painters plastic
Characteristics
Polyethylene sheeting with a denser structure than the type commonly used to wrap paintings. The same material used to make Tyvek®, its greater density allows for superior protection with a much thinner film .23mil - .35 mil is typical depending on form purchased. The manufacturing process tends to reduce the need for plasticizers and slip agents. More heat-resistant than LDPE. Thinner versions behave like a very supple non abrasive form of tissue only without hygroscopic properties.
Forms/Sizes
Easy to purchase as "food grade" bags as thin as .23 mil in smaller sized sizes from a plastics distributor, or in rolls up to 12" x 400' in .31 mil thickness as ‘painters plastic’ at home improvement centers and painting supply stores. The Husky brand product has been the most widely used version which has consistently passed oddy tests.

Applications
Can be used in much the same way as LDPE. Being thinner, smoother and less rigid than tissue, it is perfect as a protective barrier for delicate objects. Will conform readily to complex shapes without build up of bulky folds. Also a superior, inexpensive and lightweight dust cover. Lack of additives means it can be handled for long periods of time without leaving a residue or film on hands or objects. Because it is so thin it can be used to supplement pre-existing packing solutions. When used in two layers it provides a "slip sheet" effect where one layer stays with the object and the other with cushioning material that virtually eliminates risks of abrasion to fragile surfaces. Like most synthetic materials though there can be a risk of static charge with movement so it may not be appropriate for use with some friable materials.
