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

A polymeric, mono- or multilayer stretch hood packaging film with an overall density that does not exceed 0.920 g/cc includes: A. At least one core layer containing: 1. At least 50 wt % ULDPE with a density of 0.900 to 0.920 g/cc; and 2. Optionally at least one of: a. LDPE with a density of 0.915 to 0.925 g/cc, and b. EVA with a VA content of 4 to 20 wt %; and B. Optionally, two skin layers, each skin layer independently comprising: 1. At least 50 wt % ULDPE with a density of 0.900 to 0.920 g/cc; and 2. Optionally an LDPE with a density of 0.915 to 0.925 g/cc.

Stretch hoods made from ULDPE-rich formulations

Multilayer films comprising three or more layers have improved properties for a variety of applications. The multilayer films often have a total thickness of from about 10 to about 50 microns. Blown multilayer film properties may include excellent cling with reduced unwinding noise levels. Cast multilayer film properties include improved elasticity, impact, puncture, and tear properties.

Multilayer films

The invention is directed to a composition suitable for use in a single-sided stretch cling film, the composition having from 0.1 to 20 percent by weight of a propylene-based copolymer having substantially isotactic propylene sequences, and having from 80 to 99 percent by weight of an ethylene-based copolymer having a density of at least 0.905 g/cc, wherein a film made from the composition exhibits cling layer to release layer cling of at least 70 grams force per inch as measured by ASTM D-5458-95, noise levels of less than 87 dB during unwinding operations, and has a modulus of at least 3 MPA as determined by ASTM D-882.

Composition suitable for single-sided, low-noise, stretch cling film and films made therefrom
