Abstract: A method and apparatus for packaging food products in a synthetic foil. The method generally comprising transporting the synthetic foil through a punching device in which perforations are made in the synthetic foil with high energy beams to yield a perforated foil. The perforations are made in the synthetic foil to achieve a perforation surface per surface unit of the synthetic foil set according to the food product to be packaged, and the perforation surface per surface unit of the synthetic foil is achieved by controlling at least one of the number and intensity of the high energy beams projected onto the synthetic foil. The perforated foil are then formed into packages, filled with the food product, and closed to enclose the food product.

Abstract: Method for packaging products being prone to decay, such as food products, more particularly vegetables and/or fruit in a synthetic foil, wherein the synthetic foil is perforated in an operation step, converted into a package and filled. The foil is thereby conveyed through a punching device, whereby perforations are punched in the synthetic foil, the perforated synthetic foil is formed as packages having the desired dimensions and these packages are filled with the products and closed.

Abstract: A method for drying moist products includes subjecting the products to an irregular movement and collecting and discharging the moisture that is released by the irregular movement of the products. The products are moved in an irregular manner by subjecting them to an air stream which varies over time. In this way the products are dried efficiently and quickly, without risk of damaging the products. An apparatus is provided for carrying out the method, having an assembly for subjecting the products to an irregular movement, an assembly for collecting moisture released by the products and an assembly for discharging the collected moisture, wherein the assembly for irregularly moving the products includes an assembly for generating an air stream that varies over time and guiding this air stream along the products.
