<p>PURPOSE:To improve mechanical property of a container and prevent the adsorption of dust, by forming by bending operation the container of a sheet into which two transparent polystyrene films containing an antistatic agent are laminated with an impact resisting styrenes resin film interposed therebetween. CONSTITUTION:A synthetic resin made container (A) is formed of a laminated film B by bending operation. The laminated film B is the one formed into a sheet by laminating transparent styrene resin films 1 and 2 with an impact resisting styrene resin film 3 interposed therebetween and the transparent styrene resin films 1 and 2 contain a antistatic agent. The styrene resin consists of polystyrene alone or mixed with other resin such as styrene butadiene copolymer. Such copolymer is produced by adding butadiene in an amount within the range of 40-20 parts by weight per 60-80 parts by weight of polystyrene. The antistatic agent is added in an amount within the range of 2-7 parts by weight per 100 parts by weight of the resin.</p> |
