Embodiments relate to a polyester film, preparation method thereof and method for reproducing polyethyleneterephthalate (PET) container using same, the crystallization temperature (Tc) of the polyester film is not measured or is 70? C. to 130? C., as measured by differential scanning calorimetry, whereby it is possible to easily control the crystallinity. Accordingly, the polyester film has excellent shrinkage characteristics and recyclability, and clumping rarely occurs even if it is dried at high temperatures for a long period of time in the regeneration process.

The present invention relates to a process for obtaining a dialkyl phthalate and a reusable target PVC plastic from a PVC feedstock containing at least one phthalate, including: a) a solid-liquid extraction of said PVC feedstock in the form of particles by placing said particles of the PVC feedstock in contact with a solvent including at least one alcohol C.sub.nH.sub.2n+1OH with n<4 or n>8, to produce a liquid phase enriched in said phthalate and a solid phase including PVC plastic depleted in said phthalate; b) transformation of said phthalate of said liquid phase into dialkyl phthalate of formula C.sub.6H.sub.4(COOC.sub.nH.sub.2n+1).sub.2 by transesterification using said alcohol; c) a solid-liquid separation between the solid phase and the liquid phase to produce at least one solid stream including the PVC plastic depleted in said phthalate so as to obtain said target PVC plastic; d) a liquid-liquid separation of the liquid phase, to produce at least a first liquid effluent including said dialkyl phthalate and a second liquid effluent comprising said solvent.

Method of treating complex films, comprising at least a first single sheet of a polymer, preferably PET, a second single sheet of a polymer, preferably PE, and at least one layer of adhesive, preferably EVA or acrylic. The sheets are in flake form and are separated by subjecting them to a first stirring bath in hot water with at least one dicarboxylic acid and at least one fatty acid, preferably oxalic acid and oleic acid; plus a second stirring bath with a caustic agent, preferably caustic soda, and a surfactant. The PE and PET films are separated by at least one densifying bath. The PET films are then treated by means of a stirring bath, a drying silo and a foreign particle separation machine. After each bath, except between the two densifying baths, the flakes are passed through a centrifuge.
