Packaging structure having a frame and film |
摘要 |
A packaging structure useful as retention and suspension packaging. The packaging structure comprises a frame and a film connected to the frame. The film comprises first and second layers. The first layer is an outer layer of the film and comprises polyethylene polymer having a density of at least about 0.910 g/cc. The first layer comprises no more than about 20% of the total thickness of the film. The second layer comprises ethylene/alpha-olefin copolymer having a density of less than about 0.910 g/cc. The film has an elastic recovery in each of the transverse and longitudinal directions of at least about 60% measured according to ASTM D5459-95 at 100% strain, 30 seconds relaxation time, and 60 second recovery time.
