Abstract: Flexible, halogen-free films, both multilayer films and monolayer films, can replace polyvinyl chloride films in applications requiring high speed welding by high frequency radiation. The monolayer films result from a blend of a non-polar olefin polymer and a polar olefin polymer that contains carbon monoxide. The multilayer films have like that of the monolayer films, but located so as to promote high frequency sealing. Products made from such films are particularly well suited for medical device applications.

The compositions are useful for making HF-active films and articles containing such HF-active films.

The films may be mono-layer films or multi-layer films, especially where the high frequency-sealable films serve as outer or skin layers in multi-layer films. Products made from such mono-layer and multi-layer films find utility in a number of applications, especially for medical device applications.

Abstract: A multilayer film useful for making plastic adhesive labels for glass substrates such as glass bottles. The multilayer films contain a base layer, an adhesive layer, and optionally an intermediate layer to improve interlayer bonding between the base layer and the adhesive layer. The adhesive layer comprises a heat-activated thermoplastic adhesive that is not tacky at room temperature. Films of the present invention are sufficiently non blocking at room temperature so as to not require the use of a separate release liner. The film can be utilized in conventional graphics printing operations and made into labels. Labels made from films of the present invention can be thermally adhered to glass substrates and exhibit sufficient adhesion to glass substrates to withstand washing/rinsing, filling, and pasteurization processes utilized in the bottling industry.

Abstract: A multilayer film useful for making plastic adhesive labels for glass substrates such as glass bottles. The multilayer films contain a base layer, an adhesive layer, and optionally an intermediate layer to improve interlayer bonding between the base layer and the adhesive layer. The adhesive layer comprises a terpolymer of ethylene, 3-10 weight percent of an ethylenically unsaturated carboxylic acid (e.g. acrylic acid or methyacrylic acid), and 3-25 weight percent of an unsaturated ester (e.g., methyl, ethyl, or n-butyl acrylate or methacrylate). The base layer preferably comprises oriented polypropylene or oriented polyester, but may also comprise high density polyethylene or PETG. The multilayer film can be utilized in conventional graphics printing operations and do not require the use of a separate release liner.

Abstract: Disclosed is a laminated foam insulation board having enhanced strength and resistance to bending and breaking. The board comprises a panel of an insulating plastic foam material and a thermoplastic facer film adhered to opposite surfaces of the panel. The facer films have an ultimate elongation of less than 200 percent in both machine and transverse directions, a yield tensile strength of at least 7,000 pounds per square inch (48,400 kilopascals) in both machine and transverse directions, and a 1 percent secant modulus of at least 200,000 pounds per square inch (1,380 megapascals) in both machine and transverse directions. The degree of adhesion is about 100 grams per inch or more (about 39.4 grams per centimeter or more) between the facer film and the foam panel.
