A polythiourethane film comprising polythiourethane, wherein the polythiourethane is a reaction product of a bifunctional thiol compound, a trifunctional or higher thiol compound, and an isocyanate compound.

A method of forming a vacuum insulated refrigerator cabinet, the method comprising providing first and second sheets of material. The first sheet of material is thermoformed over a first forming tool forming a first intermediate structure. The first intermediate structure is then thermoformed over a second forming mold to create a second intermediate structure. The second sheet of material is then sealing connected with the second intermediate structure forming an annular space. A vacuum is created in the annular space creating a vacuum insulated cabinet.

A molding device of an inbuilt component fixing section of a fuel tank includes: a projection member that projects out at a placement face onto which a resin sheet that will form a tank configuration member is disposed in a molten state, and that molds a hollow bulge section in the resin sheet; an elastic body that covers the projection member, and that expands and applies pressure to the bulge section from the inside due to a non-compressible fluid being supplied into a sealed space formed between the elastic body and the projection member; a fluid supply device that supplies the fluid into the sealed space in a state in which the bulge section has penetrated through a fixing hole provided in an inbuilt component; and a fixing member that fixes a location of the elastic body corresponding to a leading end portion to the leading end portion.

The invention relates to a heating device (1) which is designed to heat a packaging film in a deep drawing process, over the course of which the heated packaging film is molded into the cavity of a deep drawing mold. The surface region of the heating device (1) which is brought into contact with the film section to be molded into the cavity has at least one depression (50), the opening area (40) of which equals 40 to 95% of the opening area (40) of the cavity. The invention also relates to a deep drawing device comprising the aforementioned heating device (1).

A method for producing a portion unit with at least one filled receiving chamber surrounded by a film, comprising the steps of a) transporting a first film in the direction of a heating device; b) bringing the first film into contact with a surface of the heating device; c) heating the first film by means of the heating device; d) breaking the contact between the first film and the heating device; e) molding the first heated film into the cavities of a thermoforming mold, thereby forming a receiving container with at least one receiving chamber; f) filling the at least one receiving chamber; g) optionally closing and separating the filled receiving containers, thereby forming the portion unit, wherein the region on the surface of the heating device that is brought into contact with the film has at least one depression and, in step b), the at least one depression is covered by the subregions of the first film that are molded into the cavity of the thermoforming mold in step e).
