Abstract
An individual packaging method for a liquid or solid product, includes uninterruptedly unwinding a first film, or lower film, simultaneously unwinding a second film, or upper film, with regard to the lower film, continuously dispensing, between the two films, the product which has to be packaged, and simultaneously forming and sealing the contour of each packaging by means of ultrasonic welding, this welding being carried out so that the ultrasounds eject the product from the zones which are to be welded.
Claims10
A method for manufacturing packaging containing an individual dose of a product in liquid, viscous or powder form, comprising the following steps:
- unwinding a first film, or lower film, in an uninterrupted manner,
- simultaneously unwinding a second film, or 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.
