Embodiments herein relates to a Bisphenol A-free multi-layer biaxially oriented polyester (BOPET) film, for lamination on metal sheets, which could be used for food containers. The BOPET film has at least one outer release layer, which aids in the release of food, such as a high protein food source, when food is cooked and sterilized in direct contact with the outer release layer. The BOPET film can be laminated to metals used in the manufacture of food containers with the outer release layer being exposed to allow a direct food contact between the surface of the outer release layer and food. More particularly, the invention relates to a novel outer release layer resin composition comprising an ultra high molecular weight siloxane polymer and a polyethylene trephthalate resin; and an alkali-metal phosphate and a phosphoric acid compound added, during polymerization of the outer release layer resin composition, as a catalyst/additive package to the ingredients forming the outer release layer resin composition. A wax component can be added in the outer release layer, for more robust release performance.

A method for stabilizing a composition made from PAEK, said method including a step of incorporating a stabilizing agent against thermo-oxidation phenomena, said method being characterized in that said incorporated stabilizing agent is a phosphate salt, or a mixture of phosphate salts. The phosphate salt is incorporated into the composition based on PAEK by one of the following techniques: dry blending, compounding, wet impregnation or during the process for synthesizing the PAEK polymer.

A plant-based functional polyester filament and a preparation method of the plant-based functional polyester filament are provided. The plant-based functional polyester filament includes polyester, and plant extract in a weight percentage range of approximately 0.1%-1.5%. The plant extract includes one or more of a peppermint extract, a valerian extract, a lavender extract, a wormwood extract, a chitin extract and a seaweed extract. The method includes preparing a plant-based functional polyester masterbatch, including: heating polyethylene terephthalate (PET) chips to a molten state, adding an antioxidant and a dispersant to the molten PET, stirring the molten PET, adding a protective agent and a plant extract to the molten PET, stirring the molten PET at a high speed, adding a modifier to the molten PET, obtaining a mixture by uniformly mixing the molten PET, and performing an extrusion granulation process on the mixture.

The present invention relates to an aqueous polymer dispersion suitable for use as a pressure sensitive adhesive (PSA). The aqueous polymer dispersion may be capable of a high level of performance relative to other aqueous polymer dispersions by achieving an overall balance of adhesive properties, i.e. high tack, high peel strength, and high shear strength. Without limitation, the aqueous polymer dispersion may be used for tapes, tiles, panels, slates, and the like. In addition, the invention relates to a method for making the aqueous polymer dispersion.
