Abstract

Video tape reels made from polyacetal resins need to have high dimensional precision and other properties, which are improved by incorporating in the polyacetal resin at least one surface active agent being an aliphatic amine-type surface active agent, an aliphatic amide-type surface active agent or a non ionic surface active agent. Where the video tape reel consists of two side plates, one of them may be formed of a transparent resin.
