Characteristics
LLDPE has a higher tensile strength and higher impact and puncture resistance than LDPE. It is very flexible and elongates under stress. Good resistance to chemicals and UV radiation. Common brands have passed oddy tests for contact with objects but are commonly used with some kind of barrier material.
NOTE: product is commonly misnamed “shrink wrap”, which is activated by heat to shrink-fit what it contains. Usually a form of PVC (polyvinyl chloride) - normally unsuitable for use around art.
Forms/Sizes
Widths from 2” to 30” can be used with or without a variety of handles; thicknesses range from 60 to 120 gauge (80 gauge is most common).

Applications
Initially used by shippers to stabilize loose boxes on pallets. Adapted by fine arts packers to secure moving blankets to large objects and furniture. Smaller widths used successfully to secure delicate objects inside of inner boxes. Increasingly used to add extra layer of protection to crates. Each layer of stretch adds an additional layer of “springiness”. When used thoughtfully this allows for precise levels of restraint for even the lightest, most delicate objects. Used less carefully, it can snap legs on chairs from accumulated force.
