Cold Rolling for Precision Material Thickness

Packaging substrates like display glass with fluid flow to prevent folding and minimize settling time of interleaf material. The method involves positioning the substrate on a frame, then using an arm tool with orifices that allow fluid to flow over the interleaf as it's placed. The fluid flow reduces air resistance and prevents folding. It also speeds up settling as the fluid helps the interleaf conform to the substrate shape.

Square-bottom packaging bags with reduced warping compared to traditional bags using laminated films with biaxially oriented outer layers. The bags have a unique construction and manufacturing process to minimize warping. The bag has a square bottom with folded sides and top. The outermost layer of the folded sides is a laminate without paper, using a biaxially oriented film instead. This prevents warping compared to paper-containing laminates. The manufacturing process involves folding the bags before sealing, with the folding direction aligned with the sides' rectangular opening. This reduces warping by preventing differential shrinkage between the sealing areas. The bottom is also a laminate with biaxially oriented film to further reduce warping.

A cover tape for packaging electronic components that reduces warping and curling when applied to carrier tapes to improve package alignment and prevent component misalignment during mounting. The cover tape has a multi-layer intermediate layer between the base and heat seal layers. The inner layer contains a rubber-based material to improve adhesion. The outer layer has lower rigidity. This prevents internal stresses from pulling the tape and causing warping. The reduced warping helps prevent curling when the cover tape is applied to the carrier tape.

Improved rollers/gears for pressing packaging material layers together and/or curling/bending the packaging material layers in cold seal packaging machines to prevent jamming and improve performance. The rollers have tooth profiles that mate together to press the packaging layers while also curling the edges at an angle. This avoids getting caught in machines like roller conveyors that can cause jams due to the thin, rigid, and sometimes curling nature of cold seal packaging materials.

A sustainable packaging method that replaces plastic bubble wrap with paper-based packaging articles that have similar cushioning properties. The method involves continuously supplying Kraft paper with a minimum machine direction stretch of 5% at temperatures between 10-40°C. The paper is plastically deformed to form a structured layer with embossments or flutes. This layer is then joined with a flat cover layer to create a compound layer that forms the packaging article. The paper-based packaging has a similar cushioning effect as bubble wrap but without requiring high temperatures or moisture for deformation. The packaging can be formed into envelopes, boxes, etc.

A sleeve for a packaging bag that reduces wrinkling, improves stackability, prevents discoloration, and facilitates separate disposal compared to traditional paper or plastic sleeves. The sleeve has a unique construction with a base material layer, a filler layer, and a sealant layer. The filler layer contains a filler like talc to provide rigidity and prevent dimensional changes due to moisture. This prevents wrinkling and bulging in the bag. The sealant layer bonds the sleeve to the bag to prevent separate disposal issues. The sleeve design improves the bag's stackability, appearance, and functionality compared to traditional paper or plastic sleeves.

Sleeve for packaging bags that provides improved rigidity, stackability, and ease of peeling without wrinkling when used as a packaging bag. The sleeve has filler added to the polyolefin material to increase rigidity without needing excessive thickness. A crease is formed to aid in folding the sleeve into a rectangular tubular shape. The crease helps flatten the sleeve for storage and prevents wrinkles in the bag body. The filled sleeve provides sufficient rigidity without excessive thickness compared to unfilled sleeves. The filled sleeve also allows peeling from the bag body after use. The crease helps flattening for storage without wrinkles.

A sheet packaging body with a foldable inner member that prevents shape deformation as sheets are removed. The packaging has a sheet laminate inside a film wrapping. A plate-shaped member with folds is attached to the inner surface of the film. The member can be flattened by folding at creases. The folds are fixed in place. The member and film are folded and shrunk together. This keeps the packaging shape as sheets are removed, preventing issues like difficulty removing sheets or sealing openings. The folds can be straight and parallel. The member can wrap around the center or sides of the packaging. The member can be pre-wrapped in the film before adding the sheet laminate. Alternatively, the laminate is wrapped in the film with the member attached.

A plastic-free packaging material with cushioning properties similar to bubble wrap, produced using a low-energy method. The packaging material has a structural layer with embossed areas made by permanently plastically deforming a base material like kraft paper. The embossed areas provide cushioning without adding thickness like bubble wrap. The paper is formed at room temperature to avoid energy-intensive processes. The embossed areas allow plastic deformation without tearing, providing dimensional stability.

A method to produce paper-based packaging material with reduced energy consumption compared to conventional corrugated cardboard. The method involves forming the packaging material by plastic deformation of a base paper using corrugating rollers without steam or heat. The resulting structural layer has a wave structure similar to corrugated cardboard but without the energy-intensive corrugating process. The base paper is kraft paper with high elongation to allow plastic deformation.

Flatpackable paper packaging container that transforms into a box-shaped container when filled. The container has a top sheet and bottom sheet that overlap and seal around the entire circumference. The top sheet has a spout with a short tube protruding 7 mm or less from the outer surface. This prevents the spout from snagging during flattening. The bottom sheet has a through hole and spout with a long tube that retracts into the container when closed. The short outer tube prevents spout snagging during flattening while the long inner tube allows dispensing. The container has features to allow folding and sealing for flatpacking.

Packaging substrates like glass using fluid flow to prevent wrinkling of interleaf materials when placing them between substrates. An arm tool with movable orifices flows fluid over the interleaf as it's positioned onto the substrate. This creates a fluid barrier to prevent air resistance from causing wrinkles. The movable orifices allow customization of the interleaf placement by adjusting the spacing between them. The fluid flow can be varied in amount and pressure.
