Wrappers Shrinkage TRIZ Cases

A packaging module uses adjustable guiding sections to control wrapping rod position and tension for film application.

A dual-heater packaging system uses independent peripheral and inner heating zones to seal plastic films onto supports with high precision.

Lateral heating registers utilize natural convection to reduce energy consumption while providing side access for easier maintenance.

Extending the cover film beyond the base film allows gas access via lateral edges, eliminating perforations that cause material wastage.

A dividing device forms article groups while a cutting station trims thermoplastic film to match each group size, optimizing pallet space usage.

External lifting devices move guide plates vertically to block specific nozzles, preventing product collision while targeting heat distribution.

Adhesive contact points transfer tensile forces from the carrying handle directly to beverage containers, preventing thin shrink film rupture during handling.

Recycling circuit redirects heated air from outlet to inlet, reducing heat loss and energy consumption during shutdown periods.

An internal handle strip overlaps within the heat shrink film to prevent delamination under heavy loads.

A polyester resin film maintains container adhesion during thermal processing through controlled molecular orientation.

Pressure regulating openings on the spreading element equalize Bernoulli-induced pressure differences, preventing jamming of ultra-thin foil sleeves.
