A resin composition includes polyetheretherketone, a polyetheretherketone recycled material, and a filler, wherein a percentage of the recycled material is 25 mass % or higher with respect to a total of the polyetheretherketone and the recycled material; and the filler has a content of from 5 to 30 mass % and has an aspect ratio of from 1 to 3.

Cellulose materials and methods of making the cellulose materials are described herein. The method can include contacting a cotton fabric with an oxidizing system to obtain an oxidized cotton material and processing the oxidized cotton material to form the cellulose material. The oxidizing system can include an aqueous mixture of a N-oxyl compound and a hypochlorite compound. During oxidation, the p11 of the aqueous mixture can be maintained at from 8.5 to 11. Cellulose products can be formed from the cellulose materials. For example, the cellulose products can be used to form a packaging material, a biomedical device or implant, a drug delivery material, a fiber, a textile material, a template for electronic components, or a separation membrane. Methods of making the cellulose product include dissolving or suspending an active ingredient in a medium comprising the cellulose material.

A resin composition includes 20 wt % to 70 wt % of an ethylene polymer based on a total weight of the resin composition, wherein the ethylene polymer comprises a polar comonomer; and 30 wt % to 80 wt % of an acrylate phase based on the total weight of the resin composition, wherein the acrylate phase comprises units derived from butyl acrylate and units derived from methyl methacrylate.

The present invention relates to a sustainable article for packaging which could be made substantially free of virgin petroleum-based compounds; in particular it relates to new packaging made from coloured post-consumer resin (PCR) having a high NIR absorption. A need remains to create a circular economy for coloured and/or black plastic by bringing the waste coloured and black plastic into new packaging while using Near infrared (NIR) detectable pigment in the colourant masterbatch. It is therefore an object of the present invention to bring the coloured or black plastic waste into new packaging. It has be found that a sustainable packaging in consumer acceptable black using NIR detectable pigment can be obtained by using a multilayer post-consumer resin, comprising a thinner outer layer of post-consumer resin of natural plastic waste (N-PCR); and a thicker inner layer comprising at least 50% coloured plastic waste (J-PCR).

It is provided a polymer composition including at least the following components A) 70 to 97 wt.-% based on the overall weight of the polymer composition of a polymer blend, including a1) 50 to 95 wt.-% of polypropylene; a2) 5 to 50 wt.-% of polyethylene; B) 3 to 30 wt.-% based on the overall weight of the polymer composition of a copolymer of propylene and 1-hexene, including b1) 30 to 70 wt.-% of a first random copolymer of propylene and 1-hexene; and b2) 30 to 70 wt.-% of a second random copolymer of propylene and 1-hexene having a higher 1-hexene content than the first random propylene copolymer b1); with the provisos that the weight proportions of components a1) and a2) add up to 100 wt.-%; the weight proportions of components b1) and b2) add up to 100 wt.-%; component A) has a MFR.sub.2 (230° C., 2.16 kg) determined according to ISO 1133 in the range from 1.0 to 50.0 g/10 min; component B) has a 1-hexene content in the range of 2.0 to 8.0 wt.-% based on the overall weight of component B); and the polymer composition is free from plastomers being an elastomeric copolymer of ethylene and 1-octene having a density in the range from 0.860 to 0.930 g/cm.sup.3.

Upgraded recycling polyolefin composition including a styrene-grafted polypropylene compatibilizer.

A method of combining rubbers and plastics when injection molding, and compositions usable in injection molding, are shown and described. Comminuted rubber from waste tires and waste plastics including any of high density polyethylene, polyethylene terephthalate, and polypropylene are combined and heated to melt at least the plastics. In one optional approach, both are melted. Plastics comprise from twenty to eighty percent by weight of the mixture, with rubber accounting for the balance. The mixture may be fortified with bonding, compatibilizing, and strengthening agents. The compositions may be cooled and pelletized for immediate use in injection operations.

The present disclosure provides a process. The process includes (i) providing a post-consumer recycled polypropylene (PCR-PP) having a melt flow rate (MFR I.sub.2) equal to, or greater than, 7.0 g/10 min; (ii) adding a 4,4′-oxydibenzenesulfonyl azide (DPO-BSA) to the PCR-PP; (iii) melt blending the PCR-PP with the DPO-BSA; and (iv) forming a DPO-BSA coupled PCR-PP having a melt flow rate (MFR I.sub.2) equal to, or less than, 5 g/10 min.

A white polyester film and a method for manufacturing the same are provided. The method for manufacturing the white polyester film includes: providing a recycled polyester material; physically regenerating a part of the recycled polyester material to form physically regenerated polyester chips having a first intrinsic viscosity; chemically regenerating another part of the recycled polyester material to form chemically regenerated polyester chips having a second intrinsic viscosity less than the first intrinsic viscosity; mixing white regenerated polyester chips, the physically regenerated polyester chips, and the chemically regenerated polyester chips according to a predetermined intrinsic viscosity so as to form a polyester masterbatch material; melting and extruding the polyester masterbatch material to obtain the white polyester film having the predetermined intrinsic viscosity.
