Abstract: Packages prepared from a flexible static charge-dissipating structure comprising a substrate film, a coating layer of heat sealable thermoplastic matrix containing micron sized particles of a silica containing material surface coated with antimony-containing tin oxide crystallites, and optionally a thin layer of metal, provide excellent static charge protection to sensitive electronic components.

Abstract: A multi-layered, heat shrinkable film is disclosed which possesses one or two outer layers of a polyolefin and a core layer of material having a melting point below the temperature required to orient the material of the outer layer or layers, the core layer comprising 50 to 95% of the overall thickness of the film.

Abstract: A shrink film having high optical clarity, good shrink properties, and good mechanical properties is obtained by stretching biaxially, without prior crosslinking, a film made of a copolymer of ethylene with at least one C.sub.8 -C.sub.18 .alpha.-olefin, which copolymer has two distinct crystallite melting points below 128.degree. C., the difference between these melting points being at least 10.degree. C., and stretching being carried at a temperature within the range defined by these melting points. The above copolymer may be blended with a homopolymer of an .alpha.-olefin or copolymer with another .alpha.-olefin or another ethylenically unsaturated comonomer, which may constitute up to about 95 weight % of the blend. The shrink film of this invention is particularly suitable for wrapping consumer goods which have to maintain good sales appeal.
