Bag Making Operations TRIZ Cases

Automated garment sewing system integrates edge folding, handle fitting, and bottom forming stations to standardize bag manufacturing.

Cold-stretched LLDPE/LDPE and HDPE drawstrings expand to fit wider trash receptacle openings while maintaining tensile strength.

An overseal bar creates a reinforced bottom seal structure to prevent leakage and burst during drop impacts.

Targeting flushing to sealed areas prevents nozzle clogging while preserving pouch appearance quality.

Ultrasonic welding joins polypropylene bags with spaced weld points, preventing needle perforations that weaken the fabric.

A feed element inserts cigarette papers between a tobacco pouch flap and wall, securing items via friction to eliminate adhesive maintenance.

A draw tape bag incorporates a stretched elastic strip to gather the hem and secure the liner inside a trash container.

Air or suction guides the film into a gap between pleat-forming plates, eliminating mechanical damage and formation defects during production.

A detection system uses ultraviolet or infrared radiation to identify luminescent markings on flexible sheets, enabling precise automated cutting of mesh bags.

Indented adhesive seams form mechanical bonds to prevent peeling and boost seam strength in flexible packaging.

Uniform non-linear knife cuts adhere adjacent bags along sealed edges, eliminating opening force variability across the entire pack.

Offset perforation lines create non-straight edges on tubular blown film, resolving the trade-off between manufacturing efficiency and user graspability.

A stacking device uses a gas stream nozzle to influence the falling speed of bags during deposition.

Crushed zipper segment ends reduce local thickness to eliminate gaps at the lap seal, ensuring hermetic integrity and secure consumer appearance.

Asymmetric sealing jaws form tetrahedral packages that fit rectangular boxes, resolving shape distortion during filling.

Folding a material web to form open cross bottoms eliminates tube formation steps, enabling easier filling of large bulky goods.

A tapered deformation tool elongates medical bag films to create a controlled length reserve for robust welding connections.

A flexible paper bag features a frayed peripheral edge created by controlled perforation and tearing to reduce cutting risks during handling.

Laser irradiation thins the base film layer while displacing non-oriented sealant layers to prevent fluffing and maintain liquid draining property.

Nested carrying handles fold into the filling chamber to resolve stacking volume issues and reduce material waste during production.
