The instant invention provides reinforced microcapillary films and/or foams. The inventive reinforced film and/or foam have a first end and a second end, wherein the film and/or foam comprises: (a) a matrix comprising a first thermoplastic material, (b) at least one or more channels disposed in parallel in said matrix from the first end to the second end of the film or foam, wherein said one or more channels are at least 1 &#x3bc;m apart from each other, and wherein each said one or more channels have a diameter in the range of at least 1 &#x3bc;m; and (c) a second thermoplastic material disposed in said one or more channels, wherein said second thermoplastic material is different than the first thermoplastic material; wherein said film has a thickness in the range of from 2 &#x3bc;m to 2000 &#x3bc;m.

Reinforced microcapillary films and foams

A method for processing a thermoplastic material that comprises a microwave-sensitive polymeric region, wherein the method includes exposing the microwave-sensitive polymeric region to microwaves; wherein the exposing results in an increase in the temperature of the polymeric region; and processing the thermoplastic material is disclosed.

Use of microwave energy to selectively heat thermoplastic polymer systems

The invention relates to a perforated film composition, comprising at least three layers, and wherein at least one layer is a inner layer with a softening and/or melting temperature, lower than the respective softening and/or melting temperatures of at least two outer layers, located at opposite surfaces of the inner layer, and where upon exposure to elevated temperature, the inner layer softens or melts to such an extent, that upon exposure to a compression force, a sufficient number of perforations seal in the inner layer, to impart an increased moisture barrier to the overall film composition. The invention also relates to a method of forming such a perforated film composition, packages prepared from the same, and a method of filling packages prepared from the perforated film composition.

Layered film compositions, packages prepared therefrom, and methods of use

Hollow molded articles prepared from a molding composition comprising: (A) from 95 to 60 percent by weight, based on the weight of (A) and (B), of an ethylene polymer having a density of 0.955 g/cm.sup.3 or higher, a melt index from 0.3 to 10 g/10 min, a melt index ratio I.sub.21 /I.sub.2 of from 40 to 80, and a polydispersity of from 1.8 to 10, the ethylene polymer being selected from the group consisting of i) high density ethylene homopolymers and ii) high density ethylene copolymers prepared by slurry or gas phase polymerization in the presence of a Ziegler or Phillips catalyst or prepared by polymerization in the presence of a transition metal compound catalyst containing a cyclopentadienyl or cyclopentadienyl derivative moiety; and (B) from 5 to 40 percent by weight, based on the weight of (A) and (B), of a homogeneous linear or substantially linear ethylene interpolymer having a density from 0.85 to 0.93 g/cm.sup.3, a melt index from 0.5 to 5 g/10 min, and a polydispersity of from 1.8 to 2.5 , the ethylene interpolymer being an interpolymer of at least ethylene and an .alpha.-olefin; wherein the composition has a density from 0.94 to 0.962 g/cm.sup.3 ; and a process of manufacturing hollow molded articles by molding such composition are claimed.
