Document Type and Number:
WIPO Patent Application WO/2023/120596
Kind Code:
A1
Abstract:
The purpose of the present disclosure is to provide: a masterbatch which, for PET/PEF blend molding, does not require extra molding time, can achieve stabilized molding, and further, makes it possible to obtain a good quality molded article; a preform; a blow-molded bottle; a film; a beverage product; a method for producing a preform; a method for producing a blow-molded bottle; and a method for producing a film. A masterbatch according to the present disclosure contains a polyester resin (A) comprising a terephthalic acid-derived structural unit (A-1) and an aliphatic diol-derived structural unit (A-2), and a polyester resin (B) comprising a 2,5-furandicarboxylic acid-derived structural unit (B-1) and a 1,2-ethanediol-derived structural unit (B-2). The content ratio of the polyester resin (B), determined by (formula 1), is 45 mass% to 90 wt%, and the intrinsic viscosity (IV value), measured under (condition 1), is 0.50 dl/g to 1.20 dl/g.
