A container includes a flexible bag including at least two bag sides in an opposed relationship wherein each bag side has two lateral edges, a bag closure extending from one lateral edge to another lateral edge, and a bag bottom spaced from the bag closure. The bag also includes a flexible jacket, external to the bag, the jacket having at least two jacket sides opposing the bag sides, and a jacket bottom. The jacket sides and the jacket bottom define a volume into which part of the flexible bag is disposed, such that the bag bottom is at least partially contained within the volume and is spaced from the jacket bottom.

Jacketed reclosable container

The present invention provides improved elastomeric interference films which are readily coextruded, have improved transparency, and have greater mismatches of refractive indices than those of the prior art. An improved elastomeric optical interference film comprising at least 100 alternating layers of at least first and second divergent substantially transparent elastomeric polymeric materials is provided. Adjacent layers of the first and second polymeric materials differ from each other in refractive index by at least about 0.05, and the thickness of the layers is from about 0.05 to about 0.5 micrometers. Stretching the films results in different wavelengths of light being reflected.

Elastomeric optical interference films

Laminated articles in the form of an extruded sheet have a multi-layered structure and comprise, on the average, alternating layers of coextruded polymeric thermoplastic materials, wherein one of said materials comprises a carbonate polymer. The articles exhibit good impact resistance even when scratched or notched, hydrolytic stability and transparency.
