SUS 316L Steel Square Bento | 700ml Single-Layer — Factory Direct
The Deep Features
-
SUS 316L — Beyond Standard : While most steel bento boxes use 304, this model is equipped with SUS 316L — a molybdenum-alloyed steel that offers superior resistance to acidic and salty foods. This is the grade used in medical devices and premium cookware, and it is a verifiable material advantage that B2B buyers can communicate at a premium price point.
-
Fold-Flat D-Ring Carry Handle : The transparent PP D-ring pivots from flat to upright in one motion, providing a stable single-hand carry grip when needed and disappearing flush against the lid surface when not. No protruding hardware to snag bags or scratch surfaces during storage.
-
Removable Silicone Gasket : The inner lid silicone seal is fully removable for independent deep cleaning — preventing odor and mold buildup in the gasket channel that permanently-bonded seals are susceptible to after months of daily use.
-
Press-Release Vent Valve : A center-mounted oval valve allows controlled pressure release when the lid is warm from hot food — preventing the vacuum-lock effect that makes some sealed containers difficult to open after cooling.
-
Hot-Water Base Heating : The PP base shell features a sealed lower reservoir accepting hot water for passive water-bath heating — warming the 316L steel tray from below without electricity, microwave, or additional equipment.
-
Refrigerator-to-Desk Compatible : The matte PP outer shell is crack-resistant from -20°C, allowing the box to move directly from refrigerator storage to desk use without any adaptor or additional container.
B2B FAQ
Q: What is the practical difference between SUS 304 and SUS 316L?
A: 316L contains added molybdenum, providing approximately 3× greater resistance to chloride corrosion compared to 304. For food use, this means markedly better performance against acidic foods (citrus, tomatoes, vinegar-based dishes) and salty foods (soy sauce, miso) — making it the professional choice for daily meal prep.
Q: Is the insulated bag sold separately or only as a set?
A: The insulated bag is available both as a bundled set and as a standalone bento — please contact our trade team to confirm current configuration options and MOQ for each.
Q: Can we customize the colorway of the side ear clips?
A: Yes. For large OEM orders, the color of the ear clips and handle can be matched to any PANTONE reference, allowing B2B buyers to create proprietary colorway combinations for branded product lines.
