摘要:
The present invention provides a reusable hag comprising a body portion having at least one side wall and a bottom wall defining a storage space therebetween with an opening at a top end of the body portion and at least one repair patch having an adhesive inner surface to enable the at least one repair patch to be applied over a tear in the reusable bag to enable the bag to be reused.
摘要:
Methods of forming a barrier layer on a substrate to form a halogen-free multi-layer construction configured to increase the barrier properties of the substrate are described. The barrier layer can reduce the oxygen transmission rate through the construction and can reduce the amount of air on one side of the construction. The methods include dissolving a highly amorphous vinyl alcohol polymer in a solvent to form a solution and applying the solution to the substrate. The solution is dried to form a barrier layer on the substrate. The barrier layer is continuous, relatively thin, and has a consistent thickness throughout the barrier layer, yet provides improved barrier properties. The methods can include using water-impermeable interior and exterior layers for preventing liquid water and water vapor from negatively affecting the functioning of the barrier layer, and an adhesive layer for reducing flex cracking failure of the barrier layer.
摘要:
The present invention is directed to a laminate having a first exterior surface and a second exterior surface, the laminate includes a first layer comprising a heat sealable material, a second layer comprising a cyclic olefin copolymer, a third layer comprising a metallic foil or metallized polymer material, and a fourth layer comprising a thermoplastic film or paper. The laminate provides high oxygen and/or moisture barrier properties and can withstand the corrosive effects of products containing solvents, halogens or strong acids and bases.
摘要:
A multilayer structure including a first layer; a sealant layer formed from one or more ethylene-based polymers; and a cohesive failure layer adjacent to the sealant layer and formed from a polymer blend which comprises an elastomeric propylene based polymer and a second polymer, wherein the second polymer is selected from the group consisting of high pressure low density polyethylene, high density polyethylene, ethylene acrylic acid copolymers, ethylene (meth) acrylic acid copolymers and combinations thereof is provided.
