Abstract: A matte polyester film and a method for manufacturing the same are provided. The matte 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 matte polyester film further includes a matting additive.

Abstract: 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.

Abstract: A biaxially oriented polyester film having the following physical property is provided: when cooled from the molten state at a cooling rate of 20° C/min, an observed recrystallization temperature is 175° C-200° C. The biaxially oriented polyester film is formed by a thick sheet before bidirectional stretching that is melted and extruded by an extruder and then cooled and formed on a casting roll. The thick sheet before stretching having the following physical property as analyzed by differential scanning calorimetry: a crystallization rate is less than 10%.
