Abstract: Sealable, co-extruded biaxially oriented, opaque film is claimed, with a base layer (A) contg. mainly polypropylene (PP) or a PP blend and a filler, and sealable outer layer(s) (B). Layer (B) contains a combination of inorganic and/or organic particles (P) and tert. aliphatic amine of formula (I); R1 = largely at least 18C alkyl or completely satd. 8-26C alkyl; R2, R3 = -R4-CH2OH (with R4 = largely satd. 1-6C alkylene).Also claimed is a process for the prodn. of this film, by co-extruding melts corresp. to the different layers through a sheet die, consolidating the film by cooling, biaxially stretching and heat fixing, and opt. subjecting one or both surfaces to corona or polarised flame treatment.

Abstract: A coextruded, biaxially orientated film comprising a base layer, which comprises a polypropylene or a polypropylene mixture, and at least one top layer comprising olefinic polymers. The top layer comprises a combination of inorganic and/or organic particles and tertiary aliphatic amine of the formula I (I) in which R1 essentially is an at least partially unsaturated alkyl radical having at least 18 carbon atoms or an essentially completely saturated alkyl radical having 8 to 26 carbon atoms and R2 and R3 are identical or different and are R4-CH2OH, in which R4 is an essentially saturated C1-C6-alkyl radical. The film is useful, for example, as a label or wrapping.

Abstract: Transparent, sealable, laminated polyolefin film (I) contains 2 laminated films (A) and (B). (A) is a biaxially oriented, multilayer polyolefin film consisting of a base layer of peroxide-degraded isotactic polypropylene with outer layer(s) of ethylene-propylene copolymer or a blend of ethylene-propylene butylene (EPB) terpolymer and propylene-butylene copolymer or a blend of these co/ter-polymers and polypropylene, (B) is unoriented or mono- or bi-axially oriented multilayer polyolefin film, a layer of SiOx, (C) is interposed between (A) and (B), and at least one of the two facing surfaces of (A) and (B) is corona treated so that the intensity of treatment directly after producing the corresp. film is above 36 mN/m. Pref. (A) is corona treated and coated with SiOx on a side with an outer layer, pref. by corona-treating the SiOx-coated surface, the polypropylene base layer in (A) has MFI 21.6/230 = 2-6 g/10 mins. and degradation factor 3-10 and the outer layers comprise ethylene-propylene copolymer with 2-8 wt.% ethylene, a blend of EPB terpolymer and propylene-butylene copolymer contg. 0.1-7 wt.% R, 53-89.9 wt.% P and 10-40 wt.% B or a blend of PP and EPB and/or PB ter/co-polymer with MFI = 5-20 g/10 mins., the outer layers of (A) are above 0.3 micron thick and are peroxide-degraded with degradation factor 3-15, film (B) consists of isostatic polypropylene, polyethylene. statistical or block ethylene propylene copolymer contg. mainly polypropylene, polypropylene/polyethylene polymer blend, EPB terpolymer, a blend of EPB terpolymer and ethylene-propylene copolymer or a blend of polypropylene and ethylenepropylene copolymer and/or EPB terpolymer, pref. with peroxide degradation factor 2-15, (B) is a biaxially oriented multilayer film, pref. with corona treated sealing layer(s) and pref. with the same make-up as (A), films (A) and (C) are each 10-100 microns thick and layer (C) is 20-100 nm. thick, with x in SiOx = 1.2-1.9, (I) has oxygen permeability = 10-20 cm3/m2/d/bar, and the base and/or outer layers of (A) and/or (B) contain antistatics, antiblocking additives, lubricants, stabilisers and/or low-mol. wt. resins. USE/ADVANTAGE - (I) is useful as packaging film and for the prodn. of containers, bags, wrappings, packets, cans and shaped objects. (I) has a transparent, sealable film with good oxygen-barrier and aroma-barrier properties. Film contains a chlorine-free, environmentally harmless barrier layer which is unaffected by folding and can be used on high-speed packaging machines.

Abstract: The invention relates to a co-extruded, biaxially oriented film which comprises a base layer essentially containing a polypropylene or a polypropylene mixture, and at least one outer layer containing olefinic polymers. The outer layer contains a combination of inorganic and/or organic particles and tertiary aliphatic amine of the formula I in which R is a partially unsaturated aliphatic radical having at least 18 carbon atoms or an essentially saturated alkyl radical having 8 to 26 carbon atoms, and R and R are identical or different and are R -CH2OH, in which R is an essentially saturated C1-C6-alkyl radical. The invention also relates to a process for the production of the film and to the use of the film as a label.
