Abstract
A process for manufacturing an individual packaging for a liquid or solid product includes uninterruptedly unwinding a lower film while simultaneously unwinding an upper film with regard to the lower film. The process further includes continuously dispensing, between the two films, the product which is to be packaged and simultaneously forming and sealing the contour of each packaging by ultrasonic welding. This welding is carried out so that the ultrasound ejects the product from the zones being welded.

A method for manufacturing packaging containing individual doses of a product in liquid, viscous or powder form, comprising the following steps:
- unwinding a first, lower film in an uninterrupted manner,
- simultaneously unwinding a second, upper film facing the lower film,
- continuously distributing the product to be packed in between the two films, without forming individual doses of product, separated in advance,
- simultaneously shaping and sealing a contour of each packaging packet, so that it is hermetically closed, by means of ultrasonic sealing, such sealing being performed so that the ultrasounds evacuate the product from the zones to be sealed towards packaging zones.
