<p>PURPOSE:To obtain the germ-free reduced pressure package which prevents the segregation of a germ-free powder mixture arising from vibration, etc., by sealing the above-mentioned powder mixture into the package under the specific condition of vacuum degree. CONSTITUTION:The vacuum degree at the time of reduced pressure packaging is <=600mmHg. The vacuum degree is preferably set at 200 to 400mmHg by taking the degree of damage of a packing material, etc., into consideration when the package is going to be placed under long-term vibration. The germ- free reduced pressure package is formed by a method of packaging, under a reduced pressure, the germ-free powder mixture, which is uniformly mixed into the packing material at <=600mmHg vacuum degree by using a vacuum packaging machine under a germ-free condition. The formation of the germ-free reduced pressure package by using the germ-free powder mixture previously subjected to the reduced pressure packaging is possible as well. The packing material can be sterilized by various kinds of sterilization methods, for example, gammarays and gaseous ethylene oxide, according to need.</p> |
