What Are Two-Compartment Meal Boxes?

A two-compartment meal box (also called a bento box, divided lunch container, or partitioned food box) is a rigid folding carton packaging solution featuring an internal die-cut divider wall that creates two separate compartments within a single box. This smart design allows restaurants, caterers, and meal-prep businesses to pack different food items — such as a main dish alongside sides, rice with protein, or hot items with cold garnishes — without mixing flavors or textures.

At Ecopaperbox, we manufacture custom two-division meal boxes using C1S (Coated One Side) solid bleached sulfate paperboard at 300–350gsm. The smooth coated surface delivers crisp offset print quality while the uncoated interior remains grease-resistant and food-safe.

Key Features of Our Custom Partitioned Meal Boxes

• Built-in Divider Wall — Die-cut from the same C1S board as the box body, creating two equal compartments.
• Hinged Tuck-In Lid — Secure flap closure keeps contents fresh; optional adhesive strip for tamper-evidence.
• C1S Food-Safe Cardstock — 300gsm or 350gsm Coated One Side SBS paperboard, FDA & EU compliant for food contact.
• Premium Print Surface — Clay-coated side accepts CMYK offset printing, spot colors, hot stamping, embossing.
• Folded and Glued Construction — Auto-lock bottom + glued side panels create rigid structure. Ships flat.
• Grease-Resistant Option — Aqueous varnish or PE lamination on uncoated interior prevents oil penetration.

Why Restaurants Love Divided Meal Boxes

1. Presentation Matters — Separated compartments keep plating intact even for delivery.
2. Flavor Integrity — Crispy items stay crisp; salads do not get soggy from warm proteins.
3. Portion Control — The divider naturally guides balanced portions for health-conscious diners.
4. Brand Exposure — Large lid surface is ideal for your logo, QR code, and social media handles.

C1S vs Kraft Corrugated: Why Choose Cardstock?

• Smoother Print Surface — C1S clay-coated layer reproduces fine details better than kraft porous texture.
• Rigidity Without Bulk — 350gsm C1S holds shape like premium gift box; corrugated feels flimsy.
• Cleaner Appearance — Bright white base makes printed colors pop; natural kraft dulls colors.
• Better Branding — High-end cafes and caterers prefer white C1S over brown kraft.

Sustainability Commitment

All our C1S meal boxes use FSC-certified SBS paperboard, 100% recyclable in standard paper waste streams. Unlike plastic clamshells, cardstock breaks down naturally. By choosing Ecopaperbox as your food packaging partner, you align with the global shift toward circular economy packaging.

Packing Method For Corrugated Packaging:

Generally no need to put the PE bags inside of the cartons. Since the boxes are glued a layer of cardboard, generally production time is not long enough to dry the paper box. If you tie the PE bags, the steamed water pearl will be produced inside of the bags.
