Wrappers TRIZ Cases
- Polyurethane Layer for Food Packaging Gas Barrier
Xylylene diisocyanate polyurethane layer enhances gas barrier properties and interlayer adhesion in food packaging laminates.
- Paper Retention System Using Segmented Cationic Polymers
Segmented cationic polymers decouple retention from drainage, resolving the trade-off between high machine speed and poor sheet formation.
- Water-Soluble Unit Dose Films with Layered PVOH for Dissolution and Barrier Control
Layered polyvinyl alcohol films resolve residue and migration issues by combining high-strength outer layers with soluble inner cores.
- Water-Soluble PVOH Film Dissolution and Stress Control
Optimized polyvinyl alcohol films balance complete cold water dissolution with moisture resistance, resolving residue and leakage issues in packaging.
- PVOH Polymer Blend for Oxygen-Tight Single-Layer Packaging
A polyvinyl alcohol polymer blend creates oxygen-tight packaging materials through single-layer extrusion and forming processes.
- Hygiene Packaging Unit With Segmented Adhesive Sealing
Packaging unit uses segmented edge zones with microencapsulated and pressure-sensitive adhesives for secure closure.
- Shaped Paper Surface Coating for Flatness and Watertightness
Liquid coating deposits a binding layer on shaped paper, preventing ink halo and fiber dust.
- Flexible Liquid Container Spout Obstacle Valve
Welded obstacles inside the spout channel form folds that act as a valve, preventing liquid escape without relying on material elasticity.
- Irradiated EVOH Packaging Film Oxygen Barrier
Ionizing radiation creates free radicals in EVOH layers, replacing fragile foil barriers and reducing manufacturing costs.
- Hygiene Packaging Adhesive-Free Folding Zones
Segmented adhesive patterns prevent tool interference during folding, resolving sealing reliability versus manufacturing precision contradictions.
- Cartridge with Mechanical Coupling and Plant Fiber Material
A beverage cartridge uses a mechanical coupling system to join plant fiber components without adhesives.
- Ink Composition for PTP Package Security
Vanadyl naphthalocyanine ink resolves adhesion and visibility trade-offs on aluminum PTP packages via infrared absorption.
- Composite Container Rim Separation Score Line
A circumferential score line in a composite container tubular body enables rim delamination from the carton substrate.
- Carton End Closure Panels for Secure Packaging
Hinged end closure panels prevent theft by securing the carton ends without increasing manufacturing complexity.
- Water-Soluble Package Powder Coating Lubrication
A powder coating of bittering agent on the exterior surface prevents sticking during storage while providing a taste deterrent.
- Composite Water Vapor Barrier Coating for Solar Cells
A composite layer formed by reacting metal oxide fine particles with a phosphorus compound creates a robust moisture barrier.
- Inverted Conical Heat Exchange Element for Single-Serve Ice Cream
A conical heat exchange surface rapidly freezes mixtures in disposable cups, eliminating cleaning and storage steps.
- Tabbed Seal Lacquer Coating to Prevent Sticking
A lacquer coating on the tab underside prevents sticking to container rims while maintaining seal integrity.
