Corrugated Board for Protective Packaging

Interior material for packaging boxes that can cushion and protect spherical items like eggs or fruits. The interior material is folded zigzag to create a corrugated structure with mountains, valleys, and inclined sides. The folded corrugated plate is fixed at the ends by plates to prevent deformation. The corrugated plate has receiving grooves for the lower ends of the items, and the fixed plates have corresponding grooves for the upper ends. This allows stacking multiple interior layers with handles for gripping. The upper layer has complementary grooves to engage with the lower layer. The corrugated folding provides cushioning while preventing item movement. The fixed plates prevent deformation during stacking.

Shipping packaging with improved impact protection and reduced environmental impact compared to traditional foam-filled envelopes. The packaging has walls with embossed ridges on one side that correspond to depressions on the other side. The ridges join to a smooth sheet, holding them together. This creates a cushioning effect when objects inside impact the walls. The embossing and joining avoids using foam or plastic. The embossed paper provides impact protection while the smooth sheet covers the embossed side during shipping.

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.

Producing paper packaging material with reduced energy consumption compared to conventional corrugated cardboard. The method involves forming a wave structure directly in the paper without using heat or steam. It involves deforming a paper base material between corrugating rollers to create a structural layer with parallel waves. This eliminates the need for energy-intensive corrugating processes. The paper used has specific properties like elongation of at least 5% in the machine direction. The resulting packaging material has comparable properties like strength and tear resistance compared to corrugated cardboard.

Cushioning material for packing that can be easily customized to fit varying item shapes and sizes. The packing material is a rectangular sheet with bends that allow it to compress and expand in one direction. The sheet has two flat plates connected by bends inside and outside the perimeter. The bends can be adjusted to change the compression range. This allows the plates to move closer together for thicker packing or farther apart for thinner packing. The bends also provide springiness for impact resistance. The material is made of a corrugated cardboard with wavy cores parallel to the end edges. This adds rigidity in the compression direction.

Shock absorbing material for packing that provides improved impact protection for wrapped objects during drops and falls. The material has a unique configuration that allows it to effectively absorb impacts from both vertical and angled drops. It achieves this by using double-wall corrugated fiberboard with B flute corrugations. The B flute corrugations increase the material's flexural rigidity, which raises impact absorption capacity for both vertical and angled falls. The rigidity also allows thinner walls to provide sufficient protection compared to conventional materials. This reduces material requirements while maintaining protection.

A packaging structure for protecting a product that is simple, cost-effective, and provides good support. The packaging uses a cardboard sheet that is integrally formed into a structure with at least one first support portion. This first support portion is formed by using the non-linear paper side of the cardboard on one side. This provides horizontal support for the product. The cardboard structure can also have a second support portion on the opposite side to provide vertical support. The non-linear paper side on the first support portion allows cost savings compared to complex folded structures while still providing good protection by leveraging the paper's strength.

A flexible wrapping material made of a single-sided corrugated cardboard with an expandable inner sheet that allows wrapping articles of any shape. The wrapping paper consists of a single-sided corrugated cardboard formed by laminating a corrugated board onto a flat plate. An elastic inner sheet, such as crepe paper, expands and contracts in the direction perpendicular to the corrugated wave. This allows the paper to conform to objects of various shapes by expanding and contracting around them. The corrugated cardboard provides cushioning protection while the expandable inner sheet allows custom fitting.

A packing material using corrugated cardboard that reliably holds hard or fragile objects during transportation without the need for separate wrapping materials like bubble wrap or padded envelopes. The packing material is made by sandwiching the object between two corrugated cardboard plates, with cutting lines in the center plate to deform the corrugated sections when pressed. This allows the plates to securely grip the object between the deformed sections and the undeformed sections around it. The plates can be pressed together, folded, or adhesive-bonded to hold the object. Using softer corrugated material on the inner plates can prevent damage to fragile objects. The deformable corrugated construction allows reliable holding of a wide range of objects without damage.
