Heterophasic propylene copolymer compositions may include a polymer matrix of a random propylene copolymer and an elastomeric copolymer dispersed in the polymer matrix in an amount ranging from about 10 to 35 wt. %, relative to the weight of the composition. The random propylene copolymer may include one or more comonomers in an amount ranging from about 0.5 to 8.0 wt. % of the random propylene copolymer. The elastomeric copolymer may include propylene and one or more comonomers, where the one or more comonomers are present in an amount ranging from about 15 to 60 wt. % of the elastomeric copolymer. Films may be formed from heterophasic propylene copolymer compositions. Methods of preparing heterophasic propylene copolymer compositions may include performing a multistage polymerization.

A multi-layered membrane comprising skin layers including an ethylene-based olefinic block copolymer (EBOC); and two or more core layers including a propylene-based elastomer (PBE).

A displacement device for moving a truncated cone at a base of a container from an as-blown position to a displaced position. The base includes a deep base ring between a standing surface and the truncated cone. The displacement device includes a collar sized and shaped to be received within the deep base ring. A plunger includes a head at an end of a shaft extending through the collar. The head is sized and shaped to be received within the receptacle of the collar. The plunger is movable from a retracted position, at which the head is seated within the receptacle, to an extended position at which the head extends out from within the receptacle to allow the head to contact the truncated cone and move the truncated cone from the as-blown position to the displaced position.

The present invention provides a morphology modified heterophase polymer having No-Break impact strength in the range of 500 J/m-700 J/m as per ASTM standard D256, a high melt flow index in the range of 100 g/10 min as per ASTM D1238, and a balanced flexural modulus as per ASTM standard D790. More particularly, the present invention relates to a process for the modification of morphology of heterophase propylene polymer in the presence of an initiator in the form of organic peroxide and a multifunctional unsaturated organic vinyl compound on the ex-reactor Heterophase Propylene Copolymer powder and/or pellet using special extrusion device.

The present invention is directed to a propylene polymer composition comprising at least one propylene copolymer (C-PP), and an α-nucleating agent (NU), wherein the propylene copolymer (C-PP) comprises two propylene copolymer fractions (PP1) and (PP2), wherein propylene copolymer fraction (PP1) is contained in the propylene copolymer (C-PP) in an amount of 30 to 70 wt. % and the propylene copolymer fraction (PP2) is contained in the propylene copolymer (C-PP) in an amount of 70 to 30 wt. %, the comonomer content of propylene copolymer fraction (PP1) is in the range of 0.5 to 2.5 wt.-% and the comonomer content of the propylene copolymer fraction (PP1) is lower compared to the comonomer content of the propylene copolymer fraction (PP2), and the propylene polymer composition has (a) a melt flow rate MFR.sub.2 (230° C.) measured according to according to ISO 1133 of 1 to 5 g/10 min., and (b) a comonomer content of 4.0 to 8.0 wt. %, the comonomer(s) being ethylene and/or at least one C.sub.4 to C.sub.12 α-olefin. The above propylene polymer composition has improved impact and optical properties. The invention further provides a method of producing the above propylene polymer composition and an extrusion blow molded article comprising the above propylene polymer composition.

An extruded multilayer film includes a top layer comprising a blend of a polyolefin and adsorbent silica. The adsorbent silica is 5% or more of the blend and the polyolefin is 95% or less of the blend. The multilayer film is oriented in at least one direction to cause fracturing of the top layer to provide a microporous surface exposing the adsorbent silica gel. The fractured top layer is receptive to receiving a printing ink on an exposed surface thereof with enhanced pigment entrapment and rapid ink drying. A single layer film in the form of the top layer, and also oriented in at least one direction also constitutes a part of this invention.

A method for performing a task in registration with a discrete seal in at least one material is described herein. The method involves simultaneously forming a discrete seal and a fiducial/eye mark in the at least one material. The method includes providing a detection device; providing a unit operation mechanism; and performing an operation on the material(s) in registration with the discrete seal. The task performed in registration with the discrete seal is based upon the location of the eye mark that was simultaneously formed with the discrete seal. A method of making flexible containers using cutting to form the outer periphery of the packages is described herein. Also described herein are flexible containers and container blanks made by such a method.
