摘要： An opaque polymeric film having enhanced moisture barrier and mechanical properties. The film has a base layer which includes a blend of a high crystallinity polypropylene having an isotactic stereoregularity greater than 93 % and a cavitating agent in an amount effective to cavitate the base layer.

摘要： A film structure which includes at least one layer of an olefin homo-, co- or ter-polymer having a surface-treated external surface which is printable, sealable and machinable, the layer containing, as combined slip agent and antiblock, a particulate cross-linked hydrocarbyl-substituted polysiloxane, preferably a cross-linked polymonoalkylsiloxane, and/or liquid polydimethyl siloxane. A method of producing a heat sealable multilayer film structure of improved machinability is also provided.

摘要： A process for manufacturing a metallised, flexible film of a polymeric material to provide a structure possessing high metal-to-film adhesion and little, if any, tendency toward metal fracture is disclosed. At least one polyolefin layer comprising a substantially isotactic polymer having a degree of atacticity of no more than 6% is subjected to flame treatment followed by vacuum metallisation of this surface (preferably with aluminium). The isotactic component is preferably polypropylene homopolymer. Other components include up to about 34% of an adhesive-promoting component which can be a C2 to C4 polymer, including a homo-, co-, or terpolymer, and a second isotactic polymer having a degree of atacticity from 6% to 15%.

摘要： A heat-sealable multi-layer film structure charactised by consisting essentially of: (i) an outer heat sealable layer (A), a core layer (B), and an outer layer (C), the outer heat sealable layer (A) being coextensively adherent to the upper surface of the core layer (B), and the outer layer (C) being coextensively adherent to the lower surface of the core layer (B) said outer layer (A) being formed from a polymer composition (a) consisting essentially of heat sealable resin compounded with one or more slip additives which are incompatible with polypropylene. (ii) said core layer (B) being derived from a polymer composition (b) consisting essentially of an isotactic polypropylene homopolymer compounded with one or more slip additives which are incompatible with polypropylene, and (iii) said outer layer (c) being formed from a polymer composition consisting essentially of isotactic polypropylene homopolymer in the substantial absence of slip additives; wherein the total amount of slip additive in said film structure is effective to provide the outer surface of outer layer (A) with a coefficient of friction sufficient for high speed heat sealing packaging operations but insufficient to cause substantial hazing of said structure.
