A material which can be used as a substitute for ordinary glass comprises a blend of a rigid and normally brittle amorphous thermoplastic material with one or more compatible low molecular weight resins. The material when broken, breaks into fragments which are not sharp and do not injure. A container having improved safety characteristics can be manufactured from the material and has many characteristics similar to an ordinary glass bottle-i.e. clarity, rigidity and brittleness. However when broken, the bottle shatters into fragments which are harmless and cannot be used to cut or pierce human skin. |
