Wrappers Shrinkage TRIZ Cases
- PVOH Shrinkable Films Balancing High Shrinkage and Biodegradability
This case combines PVOH grades, plasticizers, and crosslinking compounds to balance up to 85% shrinkage with controlled biodegradability.
- Water-Soluble Detergent Pouches with Sequential Shrinkage for Firm Grip
This case uses staged shrink tunnels and cooling to improve pouch surface smoothness and mechanical stability.
- Vertical Film Sealing for Taller, Fragile Products
Two film sources, conveyors, sensors, and dedicated seam cutters enable upright wrapping with less space and precise sealing.
- Dual Film Carriage Assembly for Automatic Roll Changeover
Two opposed film carriage assemblies enable automatic switching between rolls, eliminating manual intervention and downtime during film depletion or breakage.
- Shrinking Device Guide Rails With Porous Openings
Porous guide rails allow hot air distribution while maintaining conveyor stability.
- Segmented Roller Conveyor for Uniform Shrink Sleeve Heating
Alternating traction segments on conveyor rollers prevent sleeve binding and ensure uniform heating of cylindrical packages.
- Heat Shrink Tunnel Dynamic Width Adjustment
Dynamic width adjustment reduces thermal losses by minimizing empty space around narrow loads.
- Laminar Flow Shrink Oven Airfoil Design
Airfoil elements convert turbulent jets into laminar flow, preventing premature film contact and wrinkling during shrink packaging.
