<p>A method of packaging a substantially air-free product in an air-free pouch by first flattening and squeezing air from the pouch thereby reducing the pouch headspace prior to moving the pouch into a substantially air-free atmosphere. The pouch is then opened in the airfree atmosphere, is filled with an air-free product, is sealed within the air-free atmosphere, and is subsequently discharged therefrom. The opening of the pouch is aided, and additional air is purged from the pouch, by directing jets of high pressure air-free gas into the pouch during opening and filling of the pouch. -1a-</p> |
