A naturally degradable vacuum-sealable plastic bag, comprising a bag body, which is composed of layers compounded from a plurality of film layers (1, 2, 3), wherein a receiving cavity is formed in the middle of the bag body, which can be used for storing food, wherein at least one of the layers of film comprises a prodegradant material, wherein polyethylene is contained in the film material for preparing and manufacturing said multiple layers, wherein the added amount of prodegradant material is approximately 5% by weight of the polyethylene.

Thermal insulation liners

Provided herein are products, methods, and kits, for use in regulating the temperature of an object. The present invention relates to thermal insulating liners for regulating the temperature of perishable goods or temperature sensitive products. The thermal insulating liners generally may be dimensioned to fit within a container. The thermal insulating liners may be quickly collapsed and reconstructed to improve stackability and diminish the amount of space required to store the thermal insulating liners prior to use.

Multilayer films

There is provided a multilayer film comprising a starch layer and at least one other layer. The multilayer film has excellent barrier properties. The starch layer comprises a modified starch having a degree of substitution less than 1.5. Suitable other layers include polyolefins. The multilayer film finds use in packaging, particularly in packaging foodstuffs.

Partially coated films and packages formed from same

The present invention provides coated films and packages formed from such films. In one aspect, a partially coated film comprises (a) a film having two outer surfaces, wherein a first outer surface is provided by a film layer that comprises from 70 to 100 percent by weight of a polyolefin having a density of 0.860 to 0.965 g/cm.sup.3; and (b) a coating on the first outer surface of the film comprising polyurethane, wherein the coating covers less than 25% of the surface area of the first outer surface of the film and wherein the coated portion of the film exhibits an Elmendorf tear in at least one of the machine direction or cross direction that is at least 20% less than the Elmendorf tear of the uncoated portion in the same direction, with the Elmendorf tear being measured in accordance with ASTM D1922.

An elongate flattened thermoplastic tube has an inflation edge and an opposite edge. The tube includes spaced transverse seals that define sides of pouches. The tube includes lines of weakness that allow adjacent dunnage units to be separated. A frangible line of connection is disposed in one two superposed layers of the tube proximate to the inflation edge. This frangible connection may be broken to permit inflation of the inflatable pouches.

PACKAGING SHEET

A packaging sheet is described. The sheet comprises a first rigid component, a second rigid component, and a multilayer film. Each of the first rigid component and the second rigid component comprises styrenic polymer, aromatic polyester, aliphatic polyester, polypropylene homopolymer, or blends thereof. The multilayer film is a blown, coextruded film positioned between the first rigid component and the second rigid component and comprises (a) an outer layer, (b) a barrier component, and (c) an inner layer, where the barrier component is positioned between the outer layer and the inner layer. The first rigid component is coated on or laminated to a first surface of the multilayer film and the second rigid component is coated on or laminated to an opposing second surface of the multilayer film such that the sheet is not a fully coextruded sheet. Various embodiments of the sheet are also described.

GLASS CONTAINERS AND SEALING ASSEMBLIES FOR MAINTAINING SEAL INTEGRITY AT LOW STORAGE TEMPERATURES

A sealed pharmaceutical container includes a shoulder, a neck extending from the shoulder, and a flange extending from the neck. The flange includes an inclined sealing surface defining an opening in the sealed pharmaceutical container. The sealed pharmaceutical container also includes a sealing assembly including a stopper extending over the sealing surface of the flange and a cap securing the stopper to the flange. The stopper has a glass transition temperature (T.sub.g) that is greater than or equal to −70° C. and less than or equal to −45° C. The sealing assembly maintains a helium leakage rate of the sealed pharmaceutical container of less than or equal to 1.4×10.sup.−6 cm.sup.3/s as the sealed pharmaceutical container is cooled to a temperature of less than or equal to −45° C.

Lightweight plastic container and preform

A plastic container is provided that includes a hollow body portion including a lower supporting base portion; a sidewall portion extending upwardly from the base portion; and a neck portion extending upwardly from the sidewall portion. The neck portion includes a support flange having an upper and lower surface, at least one thread, and a dispensing opening at the top of the neck portion. In embodiments, a closure may be provided to form an assembly. In embodiments, the container may be comprised of PET, the weight of the neck portion from the lower surface of the support flange to a top of the dispensing opening may be 3.0 grams or less, and/or the vertical distance from the top of the dispensing opening to the lower surface of the support flange may be 0.580 inches or less. A preform and method for making a container are also disclosed.
