Abstract: A naked collation film comprises a core layer (C), an inner sealing layer (I) of polyolefinic material and an outer sealing layer (O) of polyolefin material, each sealing layer comprising at least two, and preferably three, polyolefins selected from C4, and at least one of C2 and C3 polyolefins. At least one of the inner layer and the outer layer has at least one of: i. a C4 content of greater than about 10 mol %; ii. a C4/C2 molar ratio of at least about 1.2; and/or iii. a C4/C3 molar ratio of at least about 0.15. The collation film is preferably non-blocking and has a large incompatibility window with the individually wrapped packages (P) of a naked collation package and has a strong optical performance.

Abstract: The invention generally relates to a naked collation package comprising an arrangement of individual packages, individually packaged in a polyolefinic filmic material, that are packed together in said naked collation package in a naked collation film, and there being no seal between the naked collation film and the filmic material of the individual packages. A method for forming the naked collation package and a method for manufacturing the naked collation package are also disclosed.

Abstract: An inherently ink printable multi-layer labelstock film having a substrate core layer comprising a polymeric material and at least one skin layer which is ink printable, the ink printable skin layer comprising a copolyester.

Abstract: The invention generally relates to a tactile, peelable, sealable multi-layer film comprising at least a polyolefinic core and a block copolymeric skin layer, wherein the skin layer, or each skin layer, has a thickness of from 2.8 microns to 4.5 microns.

Abstract: The present invention concerns a sealed package formed from a polymer film comprising a block copolymeric substrate and a heat sealable coating and/or skin layer on the substrate, the package being formed by wrapping the film around an article to be packaged in a manner to obtain at least one region of film overlap, and heat sealing the resulting overlapped film sections to each other to provide at least one sealed region of the package, the sealed region being subsequently openable by manually separating the overlapped film sections, effective without substantial tearing of the film at or around the sealed region.

Abstract: The invention concerns a coated biaxially oriented polypropylene film which comprises a core layer consisting of a homo-polymer of polypropylene with skin layers formed from a block copolymer of polyethylene and polypropylene, the skin layers having been treated with a primer with a heat sealable coating on each skin layer, and each coated side being readily printable with solvent and water based inks and resistant to thermal and humidity blocking, the thickness of the skin layers being selected so as to fall in the range 2.8 to 4.5 microns having a wide angle haze factor of at least 3 and not exceeding 50, coupled with a gloss (45 degrees) factor of at least 20% and not exceeding 100%.

Abstract: This invention relates to a coated polymeric film for use in a method of wrapping a ream of paper in a packaging film using a high speed, wrapping machine which is provided with tucker plates, the film having a coating on each major surface, each coated surface having a film to film COF in the range Dyn 0.30 to 0.50, one major coated surface having a coated surface to paper COF value that is greater than the COF value of the other-coated surface to tucker plate surface, the coating applied to that major surface containing an anti-blocking agent effective to regulate the COF of that surface to tucker plate surface, and greater than the quantity presenting in the coating applied to the other major surface of the film.
