POLYESTER FILM AND METHOD FOR REPRODUCING POLYESTER CONTAINER USING SAME

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.

20210323198 · 2021-10-21 ·

A method of recycling post-consumer plastic waste into mono filament for use in fused filament fabrication, injection molding, or other plastic manufacturing processes. Contaminated curbside plastic waste is sorted and granulated to uniform sized flakes. The plastic regrind is cleaned in a closed-loop wash cycle and dried at 160° F. and −70 dew point to reduce the moisture content to less than 0.03%. The effluent water is purified to be reused in the system. The flake plastic is extruded to a molten state and passes through additional melt filtration. A laser micrometer measures extrudate metrics like diameter and ovality to dynamically control feed and flow rates of the extruder to maintain diameter uniformity within 0.018 mm of target diameter.

METHOD FOR SEPARATING THE LAYERS OF MULTILAYER PLASTICS

A system and method are for separating the layers of multilayer plastics, the fragments of multilayer plastic being carried into a receptacle (1) pressurized for 10 to 60 seconds. The receptacle is pressurized using overheated vapor generated in a boiler and introduced into the receptacle until reaching a pressure between 1 and 12 bar and a temperature between 100 and 191.12° C. The fragments are then carried to a discharge tank at a relative pressure between −0.7 and 0.1 bar and at a temperature between 15 and 25° C. for between 1 and 5 minutes. The multilayer fragments are later transferred to a mechanical separation unit where the fragments are separated into fragments of single-layer plastic and, lastly, to a mechanical sorting unit where the fragments are sorted by material.
