Abstract (en)
[origin: US4627221A] Sterile packages are produced which have a shaped depression and a closure sheet sealed onto this depression. In order to furnish sterile inner surfaces for the packages, two tubes of packaging material each of which have a sterile inner surface are slit lengthwise and opened out into flat strips in order to form the depressions and the closure strip. Depressions are produced in one strip, which is underlaid with a reinforcing strip; thereafter the depressions are filled and sealed with the closure strip, which has one layer comprising the strip made from the other tube and another layer from another strip. The sterile surfaces of the strips are arranged so that they face one another.
