Bio-Packaging TRIZ Cases
- Compostable Capsule Sealing via Ultrasonic Tab Deformation
Mechanical deformation of container wall tabs during ultrasonic welding resolves the trade-off between high sealing strength and full compostability.
- Cartridge Guide Element Asymmetry Prevents Assembly Errors
A cartridge head part includes a guide element adjacent to the main guide portion to verify receptacle dimensions before joining.
- Rotating Tray Cryopreservation Device for Uniform Pre-cooling
A tilting tray mechanism rotates semen storage tubes to ensure uniform liquid nitrogen vapor exposure during cryopreservation.
- Polyester Bottle Preforms Using Liquid Aliphatic Ester Slip Agents
Liquid aliphatic esters reduce friction in polyester preforms, resolving packing density and surface defect trade-offs.
- Vacuum Packaging for Polyolefin Sterilization Strength Retention
Vacuum packaging with low oxygen transmission preserves tensile strength in polyolefin products during gamma irradiation.
- Collagen Nanocomposite Film with Silicate and Polyphenolic Acid
Dispersing silicate nanosheets in water with polyphenolic acid before mixing with collagen yields a biodegradable film with enhanced barrier properties.
- Catalyst-Free Aromatic-Aliphatic Copolyester Synthesis
Removing toxic heavy metal residues from copolyester production by eliminating catalysts through spontaneous anhydride-driven polymerization.
