Kind Code:
A1
Abstract:
This resin pellet group includes pellets (A1) containing an ethylene-vinyl alcohol copolymer (a1) and pellets (A2) containing an ethylene-vinyl alcohol copolymer (a2). Here, the drawing speed and the melt tension at 210°C of pellets (A1) are respectively 50 m/min and 10 mN inclusive to 30 mN inclusive, and the drawing speed and the melt tension at 210°C of pellets (A2) are respectively 50 m/min and 2 mN inclusive to 10 mN exclusive. Furthermore, the ethylene unit content (ECa1) of ethylene-vinyl alcohol copolymer (a1) is different from the ethylene unit content (ECa2) of ethylene-vinyl alcohol copolymer (a2). The mass ratio (A1/A2) between pellets (A1) and pellets (A2) is set to between 20/80 inclusive and 99/1 inclusive.
