e g by evacuation it is useful for the geometry of the container to be designed such that the fraction of film is as small as possible the container can be micro perforated whereby the size of the perforations is smaller than the particle size of the powder packaged therein the container can be designed in known fashion e g as flat bag flat bag with euro slot flat bag with round hole chain type bag flat bottom bag side gusseted bag stabilized bag 3 side sealed bag 4 side sealed bag tetrahedral shaped bag block bottom bag capsule or compartment package according to the invention the respective quantity of powder is packaged or sealed in a film that is soluble in the monomer e g mma polymer films that are made e g of pmma lend themselves for this purpose in this context the packaging can be implemented in the form of a bag with loose or compressed bulk powder or in the form of a compact filling surrounded in a form fitting manner by a film the thickness of the film must be sufficient to withstand mechanical loads during production and transport undamaged and to provide sufficient protection to the product against ambient influences moisture and dirt while being sufficiently thin to be dissolved partially or completely in as short a time as possible the invention shall be explained in more detail by means of examples in the following a pmma film is used to produce 3 side sealed bags using a bagger machine with vertical operation the machine is a form fill seal machine in which.
