Abstract: This disclosure relates to a film including a metal receiving layer having at least 15 wt. % of oriented lamellar crystals of a polymer, wherein the oriented lamellar crystals of the polymer have an average thickness in a range from about 1.0 nm to 25 nm as measured by transmission electron microscopy (TEM).

Abstract: Disclosed are single and multi-layer films having low haze and low density properties, comprising at least one polymeric layer and at least one density reduction agent, wherein the film has a haze ?35% and a density (D) of at least 1% lower than the density of the polymer. The density reduction agent may be added to, for example, a core layer, one or more tie layers, or a core layer and one or more tie layers. Processes for the manufacture of these films, and the use of these films as labels and packaging products are disclosed.

Abstract: Multi-layer films that are suitable for packaging and having improved sealing properties are disclosed. Some embodiments may also provide a lower minimum sealing temperature. A soft polymer is blended in a core layer and a tie layer comprising the soft polymer and, optionally, another polymer. A sealable layer is provided on the side of the tie layer opposite the core layer. The multi-layer films may be transparent, contain a cavitating agent, or are pigmented to form an opaque film. Also, the multi-layer film may be metallized or coated with a barrier coating.

Abstract: A thermoplastic multi-layer film for forming hermetic seals on packages comprising layer A comprising polyethylene, layer B comprising polypropylene, layer C comprising a copolymer, and an adhesion promoting coating applied to layer C.

Abstract: A film structure comprises a first sealable skin layer (a) of an olefin co- or terpolymer having an external surface which contains a slip/antiblock system. The slip/antiblock system comprises non-migratory particulate crosslinked hydrocarbyl substituted polysiloxane and silica antiblock particles. Layer (a) is located on one side of a core olefinic polymer layer (b). On an opposite side of the core layer (b) there is a second skin layer (c) which is ethylene homopolymer and which is free of the slip/antiblock system, optionally the second skin layer (c) is metallized.

Abstract: A film structure comprises a first outer skin layer (a) of an olefin co- or terpolymer having an external surface which is sealable and machinable, the first skin layer containing a non-migratory particulate crosslinked hydrocarbyl substituted polysiloxane, and which is located on one side of a core olefinic polymer layer (b) on an opposite side of the core layer there is a second skin layer (c) which is ethylene homopolymer and which is free of the particulate crosslinked hydrocarbyl-substituted polysiloxane of the first skin layer, the second skin layer. In one embodiment, for improved barrier properties, the ratio of particle size to thickness of the (a) skin layer ranges from about 1.25 to about 2.5.
