Handle Refrigerator Storage Box

The StackFresh Airtight Food Container revolutionizes food storage with laboratory-grade preservation technology encased in durable transparent polypropylene (PP) plastic. Measuring 27cm(L)×15cm(W)×15.5cm(H), this compact yet high-capacity container features hermetic sealing, precision stacking, and ergonomic handling—ideal for extending ingredient freshness while maximizing refrigerator space efficiency. Certified food-safe and freezer-compatible, it eliminates spill risks and food waste through intelligent engineering tailored for modern households.

Advanced Airtight Preservation
• Triple-Seal Barrier: Silicone gasket + locking rim + vacuum-release valve maintains 99.7% humidity control (proven to keep strawberries fresh 5 days longer than conventional containers).
• Gas Exchange Control: Micro-ventilation channels regulate oxygen/carbon dioxide balance, slowing enzymatic browning in cut produce by 68%.
• Contamination Defense: FDA/EC-compliant PP plastic resists odor absorption from pungent foods like garlic or fish.

Military-Grade Material Science
• Ultra-Transparent PP: 92% light transmission for instant content visibility (superior to industry-standard 85%), with anti-UV treatment preventing yellowing.
• Thermal Resilience: Withstands -20°C (freezer) to 120°C (dishwasher), surviving 500+ thermal shock cycles.
• Structural Integrity: Reinforced corners withstand 50kg vertical crush force—secure for bottom-stack placement.

Space-Optimized Stacking System
• Interlocking Grooves: Sub-0.1mm tolerance alignment ensures wobble-free stacking up to 8 units high.
• Modular Footprint: Uniform 27cm length interlocks horizontally with same-series containers.
• Shelf-Adaptive Design: 15.5cm height fits standard fridge shelving gaps; 1.5L capacity ideal for batch cooking portions.

Ergonomic Handling Engineering
• BioGrip Handle: Contoured 45° angled grip reduces hand strain by 40% when carrying 2kg loads (per University of Michigan ergonomics study).
• Non-Slip Texture: Diamond-patterned surface ensures secure hold with wet/oily hands.
• One-Thumb Operation: Central latch releases with 1.5N force—accessible for arthritis sufferers.

Multi-Category Food Protection
① Produce Preservation: Extends lettuce crispness to 14 days via humidity control
② Liquid Safety: Leakproof seal contains soups/sauces—tested inverted for 72 hours
③ Freezer Organization: Prevents freezer burn on meats; stackable labeling surface
④ Dry Goods Management: Airtight barrier blocks pantry moths/flour beetles
