Structured Corrugated Board Design for Enhanced Protection

Improved temperature insulated packaging systems for shipping perishable items like food, pharmaceuticals, and biological materials that maintain product viability during transport. The packaging uses renewable resources like cellulose-based paperboard and insulation materials like embossed tissue paper or wadded cellulose. The packaging design includes features like loops, locks, and stacked insulation sheets to secure the item and provide insulation. The paperboard folds around the insulation and item to create a sealed container. This replaces conventional foam insulation for cold chain shipping with a more sustainable, recyclable, and volume-efficient alternative.

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.
