The present disclosure discloses multilayer barrier (F) comprising: (a) at least one polyolefin core layer (A); (b) at least one barrier layer (B) on both the sides of the core layer; and (c) at least one polyolefin layer (C) adjacent to the at least one barrier layer, wherein the at least one barrier layer individually has thickness in the range of 1 μm-25 μm. It also discloses a process of preparing the multilayer barrier film. Additionally, a laminate comprising the multilayer barrier film of the present disclosure and a process of preparing the laminate is discussed. Furthermore, an article comprising the multilayer barrier film or the laminate of the present disclosure is also disclosed.

A method for the active adjustment of the profile of a film produced with blown extrusion technology, a film obtained with such method and a reel resulting from the winding of the film.

A method of forming a balloon for a medical device is provided including extruding a cylindrical tube of silicone material, partially curing the cylindrical tube, inflating the cylindrical tube, and fully curing the balloon. The cylindrical tube is partially cured by exposing the cylindrical tube to a first ultraviolet light source. The cylindrical tube is inflated within a mold to form the balloon. The balloon is fully cured by exposing the balloon to a second ultraviolet light source.

A modular disk coextrusion die is formed of a plurality of cells stacked together. Each cell includes an arrangement of thin annular disks, including at least a first cap disk, a first distribution disk, a first transition disk and a first spreader disk. The modular disk coextrusion die includes at least one channel disk having at least one inlet opening and at least two outlet openings per inlet opening. The thin annular disks are configured so that a first of the outlet openings of the channel disk is in fluid communication with the first distribution disk in the first cell and a second of the outlet openings in the channel disk is in fluid communication with the first distribution disk in the second cell. The channel disk provides for a more efficient utilization of space at the inlet of the modular disk coextrusion die and enables the feeding of up to twenty melt streams.

Disclosed herein are ethylene-based polymers having low densities and narrow molecular weight distributions, but high melt strengths for blown film processing. Such polymers can be produced by peroxide-treating a metallocene-catalyzed resin.

A multilayer film having a backing with an integrally formed polymeric liner, made in a common coextrusion process. The polymeric liner has material properties deemed to make it incompatible with the backing material, resulting in two layers that resist separation during manufacture and transportation but are hand separable in field applications and installation.
