Abstract: Disclosed are void-containing films and shrinkable films which show excellent density reduction that is retained upon exposures to high temperatures. The voiding agents are hollow glass microspheres. The shrinkable films have high shrinkage and retain their low density after processing under conditions of temperature and moisture used in typical recycling processes. The films are useful as for sleeves, labels, laminates and other shrinkable film applications, and their lower density allows them to be readily separated from soft drink bottles, food containers and the like during recycling operations.

Abstract: A cuboctahedron-shaped photo cube, comprised of six identically folded sheets of strong, but flexible transparent thermoplastic, assembled to allow the display of six two or three dimensional pieces of art or other objects. Each sheet has a square area, serving as a display panel and is accompanied by a backing sheet to press two-dimensional art firmly against it. Users access the interior by pulling a sheet from the structure. Art or objects are then placed inside the unit. To replace the removed sheet, one of its winged tabs is pinched with a thumb and forefinger and inserted into one of the available slots on the structure until it snaps into place. This action is repeated for the remaining aligned tabs and slots. The purpose of this invention is to present six display panels simultaneously without any being placed on the bottom, hidden from the viewer.
