Abstract
Provided is a method for producing recycled pellets, capable of using loss films that have been inapplicable so far including a thick loss film, a wide loss film, and a loss film made of a material that has high hardness and therefore is less likely to be bent, and also capable of producing recycled pellets similar to virgin pellets. A method for producing recycled pellets includes the steps of: twisting one or more loss films (R) continuously supplied in one direction while applying a stretch to the loss film; pressurizing a twisted part to pressure-bond contact parts of the loss film (R), thereby forming a twisted string (R); and cutting the twisted string (R) to produce recycled pellets (P). The loss film (R) is preheated at a softening temperature of the loss film (R) prior to twisting the loss film (R) while stretching it.
