Abstract

A package is formed by placing a bag, preferably made of heat-shrinkable material, in a vacuum chamber and activating hot-air blowers (9) which circulate air via heaters (16) in the closed chamber, the air trapped in the container sealed off by holding means (30) causing said container to expand due to the action of heat and swell up out of contact with the material (21), so that further increased heat convection can shrink the bag more readily back into contact with the material. The sealed, swollen bag is then torn, the chamber evacuated and the bag finally tightly sealed before the chamber (2, 3) is put under pressure again and opened. <IMAGE> [FR2502117A1]
