Integrated hinge‑connected structure eliminates separate lids; the hinged joint maintains flexible opening‑closing performance, enabling quick enclosure for grab‑and‑go deli meals, sandwiches and light take‑out dishes.
Reinforced corner rib design boosts overall structural rigidity, resisting squeezing deformation during courier transit, effectively shielding internal fillings from crushing damage.
Gentle rounded inner contour avoids sharp edges, fits thick‑cut sandwiches, baked snacks and mixed side dishes; inner space can accommodate multi‑ingredient combos without food squeezing.
Derived from crop‑residue plant fibers, entirely free of fluorine‑based additives, heavy‑metal pollutants. It satisfies cold‑warm mixed food contact demands for delis, café chains and catering service suppliers.
Stack‑optimized outer profile allows neat nested stacking for storage, cutting warehouse occupation space; embossed brand logos and pattern customization are supported for chain‑store branding deployment.

Fibre preparation: Crop residue bagasse is screened and refined under moderate beating parameters to acquire balanced tensile‑strength pulp suited for hinged container manufacturing.
Integrated mold suction forming: Special clamshell mould completes one‑step vacuum forming for base, lid and flexible hinge segment simultaneously, no extra assembly components.
Press‑thermal drying: Mold‑press dehydration under graded temperature settings removes residual moisture, consolidates hinge flexibility and anti‑crush rigidity of corner reinforcement zones.
Contour trimming: High‑precision die‑cut procedure trims excess flash along rim and hinge boundary, eradicates rough burrs for smooth opening and closing motion.
Optional post‑treatment: On demand, apply food‑safe bio‑based finishing layer to upgrade grease‑repellent performance for oily deli food.
Batch inspection & packing: Conduct sampling tests for hinge durability, compression resistance and food‑safety indicators, then nest products and seal for shipment cartons.
