The present invention relates to a process for modifying a post-consumer recycled polyolefin composition comprising the steps of (A) providing a post-consumer recycled polyolefin composition having a starting melt flow rate MFR2 (1), determined according to ISO 1133 at 2.16 kg load, 230 C., in the range of from 1.0 to 100 g/10 min, and comprising, based on the total weight of the post-consumer recycled polyolefin composition, determined by FTIR spectroscopy, (a) at least 50 wt.-% of one or more propylene (co)polymer component(s) and (b) up to 50 wt.-% of one or more ethylene (co)polymer component(s); (B) adding 0.10 to 1.50 wt.-%, based on the total weight of the post-consumer recycled polyolefin composition, of a radical initiator to the post-consumer recycled polyolefin composition and optionally mixing the components to form a mixture (1); (C) adding 0.05 to 0.50 wt.-%, based on the total weight of the post-consumer recycled polyolefin composition, of a twofold unsaturated hydrocarbon compound having the general formula (1) CH.sub.2CH(R)CHCH.sub.2, wherein R may be present or absent, and if being present, R is an aliphatic or aromatic hydrocarbon group comprising from 1 to 6 carbon atoms, and mixing the components to form a mixture (2); and (D) extruding the mixture (2) at a temperature in the range of from 180 to 300 C. to obtain a modified polyolefin composition having a final melt flow rate MFR2 (2), determined according to ISO 1133 at 2.16 kg load, 230 C.; wherein the ratio of MFR.sub.2 (2): MFR.sub.2 (1) is below 1.00. The present invention also relates to a modified polyolefin composition obtained by the process, as well as to the use of the modified polyolefin composition in the manufacture of an article, and to a respective article.

The techniques described herein relate to hydrogen peroxide plasma surface modification. In some embodiments, a method includes providing a mixture including hydrogen peroxide vapor from a source, wherein a concentration of the hydrogen peroxide vapor in the mixture is substantially stable over time. The method further includes forming a hydrogen peroxide plasma from the mixture and exposing a material to the hydrogen peroxide plasma in a chamber.

A packaging film includes a gas barrier film, an adhesive layer, and a sealant layer in this order. The gas barrier film includes a substrate layer, an anchor coat layer, and a vapor deposition layer in this order, the substrate layer includes a polyolefin substrate layer containing a polyolefin-based resin, the anchor coat layer contains a polyurethane resin, and the anchor coat layer has a thickness of 0.02 m or more. The adhesive layer is obtained by bonding an adhesive resin composition containing a polyolefin adhesive resin to the gas barrier film by melt extrusion, and the sealant layer contains a polyolefin-based resin.

Organic molecules with free acid groups and a molecular weight of greater than 140 g/mol used in combination with surfactants, are used as processing aids in the formation of extrudates and other molded materials. The compositions of this invention can be used as defined herein, or can be used with prior art processing aids, depending on the end use application. The novel materials and processes provide a useful alternative to the sole use of fluorine-based polymer processing aids.
