Abstract
A resin mixture which includes a resin of a recycled material or a resin of a virgin material and carbon black added to the resin and can make a biaxially oriented molded article by a stretch blow molding method. A resin mixture includes a binder resin, carbon black and a compound having a carbodiimide group. The mass of the carbon black is 1.0 part by mass or more and 20.0 parts by mass or less, and the mass of the compound having a carbodiimide group is 3.0 parts by mass or more and 64.0 parts by mass or less, based on 100 parts by mass of the binder resin.

A resin mixture comprising:
- a binder resin;
- carbon black;
- and
- a compound having a carbodiimide group,
- wherein a mass of the carbon black is 1.0 part by mass or more and 20.0 parts by mass or less, and a mass of the compound having the carbodiimide group is 3.0 parts by mass or more and 64.0 parts by mass or less, based on 100 parts by mass of the binder resin.
A preform comprising:
- a resin mixture;
- and
- a polyester resin
- wherein the resin mixture comprises a binder resin, carbon black and a compound having a carbodiimide group, and
- wherein a mass of the carbon black is 1.0 part by mass or more and 20.0 parts by mass or less, and a mass of the compound having the carbodiimide group is 3.0 parts by mass or more and 64.0 parts by mass or less, based on 100 parts by mass of the binder resin.
A method for producing a biaxially oriented molded article, comprising steps of:
- making a resin pellet from a resin mixture;
- making a preform from the resin pellet and a polyester resin;
- and
- blow molding the preform;
- wherein
- the resin mixture comprises a binder resin, carbon black and a compound having a carbodiimide group, and
- a mass of the carbon black is 1.0 part by mass or more and 20.0 parts by mass or less, and a mass of the compound having the carbodiimide group is 3.0 parts by mass or more and 64.0 parts by mass or less, based on 100 parts by mass of the binder resin.
