Bags TRIZ Cases

Ziegler-Natta catalyzed LLDPE skin layers eliminate external sealing additives, balancing stiffness and toughness in high-speed form-fill-seal applications.

An elastic maintaining mechanism secures the bent planar sheet, preventing spills during fluid pouring.

Vacuum sealable liner prevents paint residue buildup by creating an air-tight barrier against the tray walls.

Breathable mesh panels eliminate suffocation risks while an elliptical zipper pull enables independent operation by toddlers.

Ergonomic tapered bag uses side wall quillons and a gusseted bottom to resolve holding discomfort and dispensing difficulty in snack food containers.

A zipper tape seal uses interconnected C and J shaped members requiring downward pressure and opposing pull to open the bag.

A bistable pull-snap mechanism uses locking hinges and flexures to hold container sidewalls in an open position.

Segmented air-permeable tape on side gussets balances pressure equalization with an air-tight seal that blocks oxygen, moisture, and insect infestation.

A sealant layer with low heat initiation temperature seals an MDO film, resolving narrow sealing windows and degradation risks.

Mesh sheeting with zippers creates a versatile containment system that adapts from storage bags to netting, resolving versatility versus complexity.

Upper and lower guide panel ribs mechanically hold the printed circuit board, eliminating adhesive use and preventing friction damage.

Segmenting the closure into interlocking teeth for strength and a rail-and-groove system for sealing resolves outward force leaks in food storage.

Integrating a sachet into the zipper flange prevents child access while maintaining controlled moisture levels after package opening.

A sealing bag uses an elastomeric protruding component and a covering assembly to seal a slit through dual-direction squeezing.

An elastic rib on a flexible base bends during engagement to create a sealed barrier that prevents air and liquid flow across the closure.

Random microperforations in the internal plastic layer regulate gas exchange, preventing mold growth and dehydration while eliminating paraffin health risks.

Segmented polymer layers replace complex co-extrusion, reducing manufacturing costs while maintaining barrier properties.

Additional welding device creates elastic retaining seams in open bag side folds to provide a secure grip option.

Offset upper and lower compartments in a flexible tank reduce hydrodynamic pressure on container walls, preventing deformation.

Bulging intermediate extending part in laminated sheet container increases inner space capacity while simplifying discharge process.

Thermal sealing replaces sewing to boost line speed while maintaining seal integrity and preventing leakage.

A recloseable pouch zipper features a movable grasping flange that transitions between hidden and extended positions.

Polyethylene and starch mixtures maintain dart drop impact values while enabling ASTM D6400 biodegradation.

A bag closure device uses a connecting rod to maintain base separation from the annular film during extrusion.
