A container for liquids and other products comprising at least two layers of plastic material formed from a composite parison which, after heating is expanded by internal pressure into the shape of the finished container. The plastic material of the inner layer of the parison contains aluminum powder and provides protection against admission of light and comparable radiation to the material within the container. The aluminum powder also serves to heat the parison before blowing by reflecting applied shortwave radiation into the plastic material of the parison. |
