The invention relates to an arrangment for the continuous heat treatment and packaging of a liquid product with the object of sterilizing the product, the product being heated for a short time together with, and surrounded by, the packing material wherein it is to be enclosed. The product is introduced into a tube of flexible material whereupon the tube containing the product is introduced between two parallel metal bands, movable synchronously in their longitudinal direction, the tube being received and compressed between the bands so that the tube is transported with the bands at the same time as the cross-sectional area of the tube is reduced and the product is made to flow forward through the compressed tube in a gaplike space. Heat is transmitted to the product with the help of the metal bands (1) while the product present between the metal bands is kept under pressure. After the heating required for sterilization, the product is cooled and while it is still in the tube, is made to emerge and be freed from the metal bands, whereupon the tube and the product are divided into individual packing units through repeated transverse sealing of the tube.
