Method for protecting filled single or multilayer bag-in-box type bags against damage during transport

摘要

Method of protection of filled single- or multi-layered bags-in-box against damage during transport is characterised in that upon filling the bag-in-box with the fluid or semi-fluid substance in hermetic and aseptic conditions, still maintaining continuous hermetic and aseptic conditions a neutral gas, preferably nitrogen, is inserted over the surface of the substance into the bag-in-box, the said gas being in a quantity required for lifting the top part of the bag-in-box.
