Air cushion pouch for packaging that provides improved protection, versatility, and convenience compared to conventional air cushion materials. The pouch has a front sheet, back sheet, and sealed edges. A separate sealing sheet with an injection hole, fold lines, and partition sealing lines. The sealing sheet folds vertically to create an air pocket. The partition lines divide the pocket into left and right sections. The pouch is manufactured by combining and sealing the front/back sheets, adding the sealing sheet with the injection hole, folding it to create the pocket, and dividing it with the partition lines. This allows customizing the pocket size and dividing it into sections for better product fit and protection. The sealing sheet also has a hole for filling air into the pocket.

Packaging structure for parts that improves workability and reduces costs compared to traditional vertical partition and tray insertion methods. The packaging structure has a base sheet and a separator sheet with multiple flaps that fold outwards. The parts are placed on the base sheet and the separator sheet is folded around them. This creates separate compartments without the need for engaging cuts or pre-formed openings. The folded flaps protect the parts and prevent them from moving during shipping. The design allows packing of mixed part types without separate trays, reduces material usage compared to vertical partitions, and simplifies packing compared to interlocking cuts.

Packaging material manufacturing machine that pulls material from the inside of a roll to make products like cushioning packaging. The machine has a feed mechanism with a deflection roller to introduce the material from the roll interior. This reduces the risk of web breaks compared to feeding from the outside. The feed mechanism has a guide wall that funnels the material towards the deflection roller. The guide wall covers a section of the rollers and protrudes over them. This helps deflect the material into the rollers. The feed mechanism also has a shorter guide path compared to the roller length. The shorter path reduces the material's travel distance. The machine further includes a forming device downstream to shape the material into the final product.

A stretch hood film packaging device for safely and efficiently enclosing loads like pallets. The device has expandable adsorption units on either side of the load that attach and expand the hood film to cover the load. The adsorption units have rotating support pieces that spread the hood film when activated. This allows the hood film to adsorb and expand from both sides of the load, preventing sticking. A fixing part holds the expanded hood film in place. The expandable adsorption units improve coverage and prevent sticking compared to conventional hood film packaging methods.

A method to form a bubble valve for sealing and dispensing fluids from flexible packages. The method involves using two aligned formable films, like thermoformed sheets, where one is placed on top of the other. Channels are sealed between them to create a pathway. Then both films are thermoformed into pockets simultaneously. Finally, a separate film is sealed over the bottom of the pockets to trap air and form the bubble valve. This allows precise alignment and registration of the pockets compared to forming them separately.

Packaging material that can be used as both a shopping bag and a box. The material is made of paper and has features like overlapping bottom sections, folding walls, and reinforced areas to improve durability and usability compared to traditional shopping bags. The packaging material folds and glues together to form a box shape with a bottom made of overlapping sections. This allows it to be used as a box for storage as well as a shopping bag. The overlapping bottom sections provide strength and prevent bottom failure. Reinforced areas on the outer walls protect against tearing. The folding walls allow the material to collapse for storage when not in use.

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.
