Bags TRIZ Cases

Dome-shaped end projections and uniform profile terminations resolve leakage at sealed zones while preventing slider disengagement.

Flexible elastomeric flaps replace rigid prongs to secure liners while reducing user injury risk and improving ease of operation.

Arcuate cuts and frangible portions distort packaging film upon opening to prevent edge re-registration, solving unreliable tearing in thicker materials.

A C2C3 random copolymer composition with an ethylene-vinyl acetate additive achieves low sealing initiation temperature and high hot tack force.

Curved seal bars guide concave zipper profiles into place, preventing misalignment and reducing setup requirements.

Segmenting the container into inner and outer layers bonded along side seals improves tear resistance while reducing total thermoplastic material usage.

An isolation bag employs a chemically etched surface for reliable adhesive bonding, preventing chemical reactions while maintaining seal integrity.

A hinged cover valve vents air from polymeric bags while preventing re-entry to extend storage life.

Folded pouch flaps enable hygienic access via a container lid while maintaining an airtight seal to prevent contamination.

Mixed plasticizers in PVC containers control leaching rates while suppressing hemolysis, improving sterilization compatibility.

A flexible polymeric sheet carrier uses apertures to stabilize beverage containers for one-handed transport.

Folded protective air columns in an inflatable bag absorb shock at vulnerable corners while maintaining simple manufacturing.

Defined buckling lines press outer packaging side walls inward, securing beverage containers and preventing tipping without complex machinery.

Single extrusion merges components to resist internal forces, eliminating multi-step assembly inefficiencies.

Non-coinciding upper and lower elastic portions distribute pressure across packaging containers, resolving low sealing capability and locking member breakage.

A laminated stretched polyamide film uses a copolymer adhesive layer to achieve strong water-resistant lamination strength.

Segmented panels with reversible fold lines allow the filler to expand into a stable form that prevents sliding, while collapsing for compact storage.

A slip agent blend containing polydimethylsiloxanes with specific molecular weights reduces the coefficient of friction in ethylene-based polymer films.

Segmented sealing strips and a one-way valve prevent air leakage from external forces, maintaining freshness in vacuum bags.

An oxide barrier layer between adhesive and polyolefin prevents cyclic diethylene glycol adipate migration into medical liquids.

Flow channel profiles on pouch walls prevent wall collapse and ensure complete gas evacuation.

Snap-clip mechanism replaces noisy fasteners to enable quiet, one-handed operation.

A secure food transport bag uses tamper-proof adhesive compounds and integrated vent notches for reliable hot food delivery.

Nested inflatable bags create a buffer gap to absorb shocks, reducing reliance on solid foams and lowering packaging costs.

Inverting prior art to crush female elements preserves mating strength while generating tactile signals.

Adhesion width differences between dual easy peel tapes prevent internal separation under pressure while allowing easy manual peeling.
