Abstract
Embodiments relate to a polyester-based film and a process for regenerating a polyester-based container using the same, which not only solve the environmental problems by enhancing the recyclability of polyester-based containers but also are capable of enhancing the quality, yield, and productivity. When the polyester-based film is cut into a size of 1 cm in width and 1 cm in length, immersed in an aqueous solution of sodium hydroxide (NaOH) having a concentration of 1% by weight, and stirred for 15 minutes at 85° C. at a speed of 240 m/minute, the average particle size of the component of the printing layer separated from the base layer satisfies 15 μm or more. Thus, it is possible to enhance the quality of the regenerated polyester-based chips produced from the polyester-based container provided with the polyester-based film.
