APPLICATION / MATERIAL / VALIDATION
ENGINEERING APPLICATION ANALYSES
Scenario-led material, structure and validation guidance. These pages are engineering application analyses, not customer-result claims.
01
FOOD
This application analysis shows how a PP inner tray can organize and present mooncakes or similar foods while supporting practical packing, stacking and removal. Final suitability depends on the actual food, contact conditions, dimensions, box structure, process and market requirements, all of which must be validated for the individual project.

PHARMA
This analysis considers a clear PETG inner tray that supports a pharmaceutical component or medical device in a controlled orientation. PETG can assist visibility and formed detail, but the complete packaging configuration must still be assessed for cleanliness, contact sensitivity, handling, transport, compliance and any specified sterilization process.

INDUSTRIAL
This application analysis covers a PS tray used to position electronic parts through handling, assembly or transport. Tonghou projects target 10⁹–10¹¹ Ω surface resistance for this antistatic direction; the test method, conditioning environment, measurement locations, geometry and required service life remain project-specific acceptance decisions.

FLOCKED
This analysis examines a shaped flocked insert used when tactile quality, visual depth and product presentation are central to a premium pack. The soft surface and three-dimensional cavity can suit cosmetics, liquor and health products, while colour, flock direction, edge finish, retention and removal still require physical sample approval.

FABRIC-PVC
This analysis covers a formed PVC support with a fabric surface for liquor or wine presentation packaging. The structure can organize a bottle and accessories while creating a textile appearance, but bottle support, fabric orientation, transitions, removal space, outer-box fit and transport behavior must be checked with a physical sample.
