Occasionally the housewife places the food in a plastic bag and heat-seals it in such a way that a large amount of air is trapped therein. The bag then floats rather ineffectively on the surface of the water, and a satisfactory heat transfer from the water to the food is not obtained. Sometimes as much air remains in the fact that the bag tears and its contents to the boiling water gives off "Hin considerable Xach- part consists in the known" Boil-in-J3eutel "-Hethode that the boiling person is not able to take a sample in the course of cooking, to season or to assess the contents «If the heat seal of one of the

The invention now provides an improved method for the production of food in synthetic resin bags and bags, which allow the contents to be examined as the boiling or heating progresses, and v; obei the bag is conveniently filled or emptied and reused can be.

According to the invention these advantages are obtained by a process for the production of food, in which a certain amount of food is brought into a flexible, synthetic resin bag or sack that seals the food-containing bag, brought into a liquid and heat from the liquid through the Bag is transferred to the food contained therein, which is characterized in that a synthetic resin bag is used, which consists of a film that is used in

If the compressed hohr is sealed transversely and then the sealed ropes are separated from one another, bags are obtained which are eminently suitable for the invention. Optionally, however, pre-formed tongue and recess parts can also be attached or heat-sealed to a pre-formed bag or a film or several films, from which a bag or sack is then produced.

In the transverse sealing of the tubes, care must be taken that the recess and tongue do not interact to form a leakage path at the edge of the bag. Pas mouthpiece of the pouch will
