This large 72oz stackable bento box is built for those with higher caloric needs or longer days away from home. The three-layer design provides significant volume while maintaining a narrow vertical footprint. Built primarily from Food-Grade Polypropylene, the base is designed for microwave transparency, allowing food to heat evenly without creating localized hot spots. The inclusion of a ventilation plug is a practical feature that helps prevent suction lock after heating.
Specifications show the use of Thermoplastic Rubber (TPR) for the gaskets. While these help monitor spills, they may lose some elasticity after approximately 50 intensive cleaning cycles. To ensure the side-locking hinges last as long as possible, avoid over-packing the containers, which can put unnecessary tension on the 1.8mm walls. The material is rated to handle temperatures between -20°C and 120°C, making it suitable for standard reheating but not for high-power boiling settings.
The unit includes a molded utensil tray and sauce containers to keep condiments separate from main dishes. Because Polypropylene is naturally porous, tomato-based sauces may cause staining if left for long periods. A quick alkaline soak can help maintain the black finish. Functional highlights include:
- Large capacity ideal for adult portion sizes.
- Stackable tiers that allow for flexible meal combinations.
- Built-in ventilation to manage steam pressure.
For a more durable alternative that utilizes metal components, you might consider the Time4Deals Stainless Steel Bento for enhanced resistance to odors and staining.
