The present invention relates to a blown film made of a composition comprising a) a propylene heterophasic copolymer (A) with a matrix propylene polymer and an ethylene-propylene-rubber characterized in that the film has been monoaxially oriented in the machine direction with a stretch ratio of 1:1.1 to 1:10, to a process for making such a film, to the use of said composition in making such a film, and to an article comprising such a film.

Polypropylene film with improved balance of mechanical properties

A polypropylene composition comprising a random propylene copolymer, a high melt strength polypropylene having a branching index g' of 0.9 or less, a polypropylene having a MFR(230&#xb0; C.) of at least 400.0 g/10 min and a clarifier, wherein the polypropylene composition has a MFR(230&#xb0; C.) of at least 2.0 g/10 min.

Extrusion blown molded bottles with high stiffness and transparency

A polypropylene composition comprising a random propylene copolymer, a high melt strength polypropylene having a branching index g' of 0.9 or less and a clarifier, wherein the polypropylene composition has a MFR(230&#xb0; C.) of at least 2.0 g/10 min.

Certain embodiments provide an article comprising a substrate, wherein the substrate is extrusion coated with a composition comprising a multi-branched polypropylene having a g' of less than 1.00. In certain embodiments, the substrate is extrusion coated with a composition comprising a polypropylene material. Either the composition and/or the polypropylene material are represented by the equation:Vicat[&#xb0; C.]&#x3e;&#x2212;3.96&#xb7;[mol %]+86.85;wherein Vicat B is the heat resistance, according to ISO 306 (50 N), of the composition and/or the polypropylene material; and Cis the comonomer content the composition and/or the polypropylene material.

Extrusion coated substrate

The present invention relates in a first embodiment to a polymer film comprising a propylene random copolymer with a total comonomer content of 4.5 to 12 mol % wherein the sealing initiation temperature SIT of the film is T&#x2212;30&#xb0; C. or less, preferably T&#x2212;33&#xb0; C. or less, in a second embodiment to a polymer film comprising a propylene random copolymer with a total comonomer content of 4.5 to 12 mol % wherein the film is having a relative reduction of the static friction value (inside-inside) from one to four days of 35% or more, preferably 40% or more, in a third embodiment to a polymer film comprising a propylene random copolymer with a total comonomer content of 4.5 to 12 mol % wherein the distribution of the comonomer in the random copolymer determined according to TREF method is multimodal, preferably bimodal, in a fourth embodiment to a polymer film comprising a propylene random copolymer with a total comonomer content of 4.5 to 12 mol %, wherein the copolymer is having an elution interval of 50&#xb0; C. or more, and in a fifth embodiment to a polymer film comprising a copolymer with a total comonomer content of 4.5 to 12 mol % wherein the random copolymer is a unimodal polymer and the elution interval is determined by the equation4.5&#xb7;16wherein Y is the elution interval in &#xb0; C. andm is the percentage of ethylene in the copolymer in wt. %.

Polymer film comprising a propylene random copolymer

The invention relates to a process for producing a polypropylene film having a small dynamic coefficient of friction (CoF) and to a film obtained by this process. The invention further relates to the use of a polypropylene composition in a film forming process in order to reduce the required amount of slip agent for achieving a certain CoF and, alternatively, to the use of a polypropylene composition in a film forming process in order to reduce the required storage time for achieving a certain CoF.

Process for producing polypropylene film

Polyolefin fibers and polyolefin yarns of high strength and elongation and textile fabrics produced therefrom, which consist of modified propylene polymers, unmodified propylene polymers and adjuvants, are produced by melting the polyolefin mixtures in the extruder, transferring the melt by extrusion pumps to the spinnerets and drawing off the extruded filaments by high-speed galettes and/or winders.

Process of making polyolefin fibers

A nonwoven layer of sheeting is extrusion-coated on one side with ethylene polymers, propylene polymers, modified propylene polymers and fillers. The nonwoven layer of sheeting is formed from polyethylene, polypropylene, polyethylene terephthalate and/or polyamide. The coated nonwoven sheeting is subjected to longitudinal and transverse stretching and white crackling cloudiness develops. The extrusion-coated nonwoven sheeting has a textile texture and is suitable for use in hygiene products, in medical products, in the textile and clothing industry, in the automobile industry and in construction products.
