Various polymeric barrier compositions are described which when formed into films, are useful in reducing transmission of odors. The films can be incorporated into a wide range of products such as multilayer barrier films used in medical applications and particularly in ostomy appliances. In certain versions, the films include semi-crystalline cyclic olefin copolymers.

Barrier films

Various polymeric barrier compositions are described which when formed into films, are useful in reducing transmission of odors. The films can be incorporated into a wide range of products such as multilayer barrier films used in medical applications and particularly in ostomy appliances. In certain versions, the films include blends of amorphous cyclic olefin copolymers and semi-crystalline cyclic olefin copolymers.

Flexible barrier films containing cyclic olefins

Processes for forming a thermoformed labeled article are described. Labels are attached to a sheet to be thermoformed or to a section thereof. Label attachment can optionally use an adhesive. If the label material is completely or partially compatible with the sheet then the use of adhesive may not be necessary. The labels may also receive various graphics or other designs, such as by printing. After appropriate placement of the label relative to the sheet, the assembly of both sheet and label is thermoformed. After thermoforming, a finished and labeled article is produced. Also described are various labels and label assemblies which are uniquely suited for use in the processes described herein.

Thermoform labeling

Various barrier films are described that include barrier layers that contain ethylene vinyl alcohol copolymers and elastomers. Polyolefin elastomers can be used such as ethylene octene copolymers. The barrier films can also include secondary barrier layers that contain one or more norbornene copolymers.

Low noise flexible barrier films

Compositions comprising from about 30% to about 95% of one or more RF-active functionalized ethylene copolymers and one or more propylene based plastomers are described. When formed into films or thin layers, the films exhibit a combination of low noise properties and good RF weldability characteristics. Also described are multilayer assemblies using such films and various articles incorporating such. Also described are methods of determining minimum thicknesses of an RF weldable layer in a multilayer film using the compositions.

Blends of ethylene copolymers and propylene based plastomers in multilayer films for low noise and RF welding

A heat shrinkable label comprises (A) a heat shrinkable film comprising at least one thermoplastic polymer, and (B) a curable adhesive comprising (1) at least one urethane (meth)acrylate resin having an average of about 1 to about 1.6 (meth)acrylate groups per resin molecule, (2) at least one tackifier, and (3) at least one photoinitiator, where the film has an ultimate shrinkage at 135&#xb0; C. of at least 15%, and the adhesive has sufficient precure tack, wherein the loop tack of the uncured adhesive is at least 4.3 g/cm. The heat shrinkable label is useful in high-speed industrial processes such as beverage container labeling.
