    摘要: This invention relates to a biaxially oriented polypropylene (BOPP) film comprising a polyolefin-containing base layer with at least 1 weight percent recycled polyolefin material comprises polyhydroxy amino ether polymer (PHAE) and an amount of compatibilizing agent such that the laminate film has a gel count of less than 15 gels/80 in2. The laminate film could have an optional tie-layer which could comprise PHAE adhered to one side; the polypropylene film contains an amount of reprocessed PHAE-containing film and a compatibilizing agent to reduce significantly or eliminate visual defects such as gels, voids, etc. The use of the compatibilizing agent with the reprocessed PHAE also aids in improving subsequent biaxial film orientation and maintains film properties. The film of the embodiments of the invention has excellent appearance and aesthetic properties and can be suitable for transparent, white opaque, or metallized film applications depending on formulation.

    摘要: The present invention is a multi-layer film which has an improved composite structure for providing hermetic seals to packages manufactured in high speed packaging apparatus. The structure of the multi-layer film of the present invention includes a main substrate and a sealant layer. The sealant layer, in turn, includes two components, an intermediate layer which has the primary function of compliance during sealing, and a sealing layer which has the primary function of providing adhesivity to the completed seal. As a result of this invention, high strength hermetic seals can be provided to multi-layer films effectively and efficiently, and hermetic seals are provided with the ability to be peeled open without destruction of several layers of the film.

    摘要: A method for the extrusion of polyethylene resins, especially linear low density polyethylene resins and; more particularly, a method of high shear extrusion through the intermediary of which the frequently encountered melt fracture; for instance, such as the sharkskin melt fracture of linear low density polyethylene can be either reduced or even completely eliminated by effecting the extrustion at a high shear rate or shear stress over the lip section of a tubular or sheet extrusion die.
