Package Recycling TRIZ Cases

Integrally molded cup cover uses a C-shaped recess and arc walls to engage the cup body edge.

Foldable inner packaging case paper transforms circular cigarettes into stable special shapes, preventing deformation during storage and transport.

A recyclable retort polyester film uses a specialized heat seal layer to bond directly with recycled PET layers.

Segmented panels and heat-sealed gussets resolve the trade-off between structural durability and compact storage in reusable packaging.

Cutinase enzymes selectively degrade polyurethane adhesive layers in multilayer packaging structures.

A plastic film sheet with integrated foamed strips protects cylindrical reel edges during handling and transport.

Rod pockets and self-attaching straps replace wasteful shrink film, reducing wrapping time while maintaining load stability.

An integrated spring valve design merges the return mechanism with the element to ensure consistent contact and reliable operation.

A reusable bottle cap system integrates an identification marker and a protective cover to secure the closure.

Axial key insertion displaces the pawl from strap teeth, enabling safe strap release without cutting tools or torque.

A hybrid rigid frame and flexible film lid permanently attached to a tray enables one-step opening.

A cardboard packaging system featuring a segmented tray that folds flat for recycling while maintaining structural integrity during use.

A collapsible reel constructed from corrugated paperboard with a segmented core and flanges.

Segmented zones position the grip above the mouth to prevent oblique leakage while an intermediary seal prevents tunneling at joining edges.

A check valve with a pendulum flap minimizes residual fluid volume in transport containers.

A modified vinyl alcohol-based resin composition with layered inorganic compounds enhances water vapor barrier properties.

Composite iron frame and plastic pallet motor packaging resolves moisture damage and waste issues through foldable guardrails and interlaced connecting rods.

Spring steel securing devices prevent post kinking and bundle separation by locking through apertures, eliminating bulky crate transport costs.

A non-rubberized undergarment uses tension-inducing weave patterns to conform securely to the wearer.

Segmenting the lid opening via tear guides resolves spillage risks while enabling easy access to viscous food products through a dedicated spout.

Dual coatings on a repulpable paperboard tray prevent liquid leakage and wicking while eliminating polystyrene environmental harm.

Tapered walls and a disposable liner protect perishable goods from moisture while enabling stable stacking for repeated container reuse.

Composite cardboard with a non-permeable coating and folded brim prevents leakage while maintaining environmental benefits.
