发明名称 A method of producing interiorly sterile, cup or beaker shaped containers
摘要 The disclosure relates to a method of producing interiorly sterile, cup or beaker shaped containers. A starting material for the containers is produced by mixing inorganic filler with a thermoformable polymer material in such a mixing ratio that the quantity of filler in the produced starting material is at least 40% of the total weight of the mixture. The starting material is extruded into a continuous web which is heated to a temperature suitable for thermoforming of the web, at least 190 DEG C, and is fed into a forming machine of conventional type for thermoforming of the web under vacuum at the above-mentioned temperature for forming web-like continuous, interiorly sterile, cup or beaker shaped containers. The containers are finally separated from one another by incisions in the web regions between the opening contours of each respective container.
