Processing method of recycling pet material from bags

A processing method of recycling PET material from bags, the bags respectively having a body for holding things, a zipper and a fastener;

• the body made of a material consisting of a layer of polyethylene terephthalate (PET) woven fabric, a layer of PET knitted fabric, and a layer of polyurethane (PU) coating located between the PET woven fabric and the PET knitted fabric, and the zipper and the fastener both made of a PET material, the processing method comprising the following steps:
• a breaking step, in which a breaker machine is used to cut the bags so as the body is cut into a plurality of PET broken pieces, and the zipper and the fastener are cut into a plurality of PET fragments;
• a blending step, in which the PET broken pieces and the PET fragments are put into a blender machine for blending and rubbing with one another, then temperatures of the PET broken pieces and the PET fragments are risen to a frictional temperature for melting their surfaces, and the PET broken pieces and the PET fragments become adhered to one another to form a plurality of plastic granules with different sizes;
• a shaping step, in which the plastic granules are put into a first shaper machine to be thermally plasticized into a continuous plastic bar;
• a first pelletizing step, in which the continuous plastic bar is cooled in a first pelletizer machine to form a cured plastic bar, then the cured plastic bar is cut by the first pelletizer machine into a plurality of recycled plastic pellets having a same size;
• a modifying and shaping step, in which the recycled plastic pellets and a compatibilizer are put into a second shaper machine to be thermally plasticized into a continuous modified plastic bar;
• and
• a second pelletizing step, in which the continuous modified plastic bar is cooled in a second pelletizer machine to form a cured modified plastic bar, then the cured modified plastic bar is cut by the second pelletizer machine into a plurality of modified plastic pellets having a same size.
