The present disclosure provides a process. In an embodiment, the process includes providing pellets of a regrind material. The regrind material is a post-consumer recycle multilayer film (PCR multilayer film) having at least three layers. The PCR multilayer film is composed of (i) a polyethylene layer, (ii) a polyamide layer, and (iii) a tie layer. The tie layer is composed of maleic anhydride grafted substantially linear ethylene polymer (MAH-g-SLEP) having a Mw/Mn from 1.5 to less than 3.5 and a melt index from 0.5 g/10 min to less than 25 g/10 min. The process includes extruding the pellets to form an extrudate, molding the extrudate, and forming, with the extrudate, a molded article having a surface. The surface of the molded article has a surface roughness value, Sa, less than 1000 nm and a root mean square roughness value, Sq, less than 1400 nm.

A polyester film and a method for manufacturing the same are provided. The polyester film includes a physically recycled polyester resin and a chemically recycled polyester resin. The physically recycled polyester resin is formed by a plurality of physically recycled polyester chips. The chemically recycled polyester resin is formed by a plurality of chemically recycled polyester chips and mixed with the physically recycled polyester resin. The plurality of chemically recycled polyester chips further includes chemically recycled electrostatic pinning polyester chips. The chemically recycled electrostatic pinning polyester chips contain electrostatic pinning additives, and the electrostatic pinning additives are metal salts. Expressed in percent by weight based on a total weight of the polyester film, a content of the electrostatic pinning additives in the polyester film is between 0.005% and 0.1% by weight.

A process for producing a polyester composition from recycled polyesters.

The present invention concerns a process for decolorizing a polyolefin composition, the process comprising the steps of a) providing a polyolefin composition comprising at least one polyolefin and at least one organic chromophore, b) mixing the polyolefin composition in a melt state at a temperature of 170 to 290° C. with an inorganic oxidizing agent, wherein the inorganic oxidizing agent is selected from the group of inorganic peroxides and hypochlorites, and c) obtaining a decolorized polyolefin composition.

A method for recycling a polyester fabric is provided. The method includes providing a polyester fabric that is dyed and has dye and water repellent attached thereon, providing a composite solvent containing water and acetic acid mixed with each other, performing an extraction operation including infiltrating the polyester fabric with the composite solvent and extracting the dye and the water repellent, and carrying out a liquid state polycondensation reaction on the polyester fabric so that an intrinsic viscosity of the polyester fabric is increased and residual impurities of the polyester fabric are further removed.

A white polyester film and a method for manufacturing the same are provided. The white polyester film includes a physically recycled polyester resin and a chemically recycled polyester resin. The physically recycled polyester resin is formed by a plurality of physically recycled polyester chips. The chemically recycled polyester resin is formed by a plurality of chemically recycled polyester chips and mixed with the physically recycled polyester resin. The plurality of chemically recycled polyester chips further include chemically recycled electrostatic pinning polyester chips. The chemically recycled electrostatic pinning polyester chips contain electrostatic pinning additives, and the electrostatic pinning additives are metal salts. Expressed in percent by weight based on a total weight of the polyester film, a content of the electrostatic pinning additives in the polyester film is between 0.005% and 0.1% by weight. The polyester film further includes a white additive.
