Method for producing container
Abstract:
Provided is a production method for a container, including the steps of: inflating a material in a mold by direct blowing, the material including a polyamide resin composition containing 0.01 to 2 parts by mass of a crystallization promoter and 100 parts by mass of a polyamide resin obtained by polycondensation of a diamine component containing 70 mol % or more of m-xylylenediamine and a dicarboxylic acid component including an α,ω-linear aliphatic dicarboxylic acid having 4 to 12 carbon atoms and an aromatic dicarboxylic acid at a molar ratio of 97:3 to 90:10; and retaining the material in the mold whose temperature is controlled to 0 to 60° C., for a time beginning immediately after the direct blowing and lasting for 30% or more of a semi-crystallization time at cooling of the polyamide resin composition under a constant temperature of 160° C.
