A PROCESS FOR THE MANUFACTURE OF A SACHET.

摘要

The invention relates to a process for the manufacture of dual compartment sachets for packing two materials used as compositions for purification of water where the weldable materials are chosen to prevent interaction of materials stored in the two compartments and also interaction with outside atmosphere. Water purification compositions packed in these sachets are especially useful for removal of microorganisms like bacteria, viruses and cysts to make the water suitable for human consumption. The invention particularly relates to a form, fill and seal process for the manufacture of a sachet comprising at least two compartments where the weldable materials used for forming the outer walls and the inner partition layer are chosen to prevent interaction of materials stored in the compartments and also interaction with outside atmosphere.
