Abstract: The invention relates to a sealing tool (100) with a sealing surface (110) for sealing sheets (200) of metallized substrate, such as metallized paper or metallized plastic material, in cooperation with a sealing tool counterpart (190), which is arranged opposite to the sealing tool (too) with respect to the sheets (200) that are to be sealed. The sealing surface (no) comprises a plurality of sealing sections (111-115), which all face in the same sealing direction (SD) of the sealing tool (100), and has a sealing width extending transversely to the sealing direction (SD) of the sealing tool (100) from an outer sealing tool side (121) to an inner sealing tool side (122). The sealing sections (111-115) are arranged side by side in a stepwise manner so that, from the outer sealing tool side (121) to the inner sealing tool side (122), every sealing section (111-115) is offset from its neighbouring sealing section (111-115) in a direction opposite to the sealing direction (SD) of the sealing tool (100).

Abstract: The present invention relates generally to the field of polymer dispersion coated, paper-based flexible packaging materials. In particular, the present invention relates to improving the barrier properties of polymer dispersion coated 5 paper-based flexible packaging materials. Embodiments of the present invention relate to a process for improving the barrier properties of polymer dispersion coated paper-based flexible packaging materials comprising the step of applying an Al2O3 coating to at least one surface of the dispersion coated paper-based flexible packaging materials, for example by using atomic layer deposition; and an Al2O3-coated paper material 10 obtainable by such a process.

Abstract: The present invention relates generally to the field of multi-layer flexible packaging material. In particularly, the present invention relates to a multi-layer flexible packaging material comprising a paper layer, an aluminium layer, a nanoclay barrier coating layer, and a sealing layer applied to the surface of the nanoclay barrier coating layer representing the inner surface of the multi-layer flexible packaging material, said multilayer flexible barrier material being deprived of a polyolefin layer, such as a polyethylene (PE), polyethylene terepthalate (PET) or a polypropylene (PP) layer. The present invention further relates to the use of the multi- layer flexible packaging material in accordance with the present invention to package dry food.

Abstract: The present invention concerns a kit of parts comprising a cooking bag for storing food to be cooked in a microwave oven, the cooking bag having a cooking bag opening, and a pressure release closure device, configured for restricting the cooking bag opening when attaching the pressure release closure device at the exterior of the cooking bag thereby contracting the cooking bag opening so as to establish a steam conduit whereby gas pressure in the cooking bag may be released from the cooking bag during cooking in a microwave oven. Further the present invention relates to a pressure release closure device and a method of preparing food using a pressure release closure device.
