SOLUTION: Fragments of the glass bottle obtained by crushing the glass bottle using a thermal impact process at least at not less than 300 deg.C and fragments measuring not more than 10 mm obtained from the bottle of a polyethylene terephthalate resin, are mixed in the ratio of 100 wt.% for the former and 40 to 100 wt.% for the latter.
