Packaging MEMS devices with hermetically sealed cavities at a lower cost compared to traditional methods. The packaging involves forming headspace walls around the components of each MEMS device using a lower polymer layer applied to the device tops. This creates individual hermetic cavities for each MEMS device without needing separate cavity forming steps. Internal dividers can also be formed concurrently with the headspace walls to further subdivide the cavities. Pillars/fins for supporting caps and separating walls are also formed simultaneously.

A complex of folded sheets that can be stacked and assembled to form a package in a single run. The complex has a continuous rim around the folded sheets that allows the package to be made without seams or joints. The rim allows the package to be formed by bending and connecting the sheets at the rim. This eliminates the need for separate gluing or sealing steps. The complex can be made by die-cutting sheets with matching rims, and the sheets can be stacked and folded in a specific sequence. The complex is then assembled to form the package. This allows automated production of leak-proof packages without requiring additional sealing steps.

Method, mold, and equipment for cutting packaging films like aluminum blister foil used in sealing containers. The method involves continuously feeding strip film, pushing it into a mold with an upper die, lower die, and pressing plate. The lower die cuts out the packaging film while the upper die and pressing plate hold the strip. The mold ejects the film while the feeder pushes more strip. A separate waste clamp extracts leftover strip. The mold design allows precise positioning and cutting of the film while reducing waste compared to conventional methods.

Method for efficiently producing customized cigarette packaging with rapid changeover between different designs. The method involves continuously feeding a web of packaging material into a machine that separates blanks for individual packs. Instead of switching bobbins or blanks for each new design, the machine can dynamically modify the blank shapes using movable cutting tools. This allows on-the-fly customization of the blank shapes to match the desired pack design without stopping the machine. The blanks are then formed into packs using a packaging machine specific to the pack type.

Method to manufacture paper packaging with recessed areas for containing items, that reduces wrinkles and microcracks compared to conventional methods. The process involves pretensioning the paper web material before forming the recesses. This prevents wrinkles and allows reliable shaping without excessive stress. The pretensioning step uses clamping jaws and tension rollers to tighten the paper in both directions. The forming step uses a die, hold-downs, and pneumatic pressure to mold the paper into the recesses. The hold-downs are moved to feed the paper during forming to prevent wrinkles. After forming, the recessed packaging is removed from the die. This two-stage shaping process prevents tearing and reduces wrinkles compared to direct molding.
