Meal boxes

Kraft meal boxes, noodle boxes and compartment trays

Four box formats for hot food: tuck-corner kraft boxes, corrugated boxes with a window, tall noodle boxes, and divided trays. The choice is usually decided by two things — how wet the food is, and whether the box has to be visible on a shelf.

The box is decided by the food, not by the catalogue

A dry bakery item and a curry in the same box will not perform the same. Grease and moisture move through board at different rates, and the corner seams are where they arrive first. That is why the box range is specified by food type rather than by size alone: kraft tuck boxes for rice and grilled items, corrugated for bakery and retail, noodle boxes for high-moisture pasta, compartments where wet and dry must not meet.

The window deserves its own sentence. A PET or PLA window makes the pack a multi-material item, which changes both its recyclability grading and any plastic-free statement you might want to make about it. That is a design decision with a paperwork consequence, not a decoration.

Formats and dimensions

Every size below is a tooled size held in this range. Dimensions are nominal — confirm tolerances before artwork or lid tooling is committed.

Kraft meal boxes

One-piece kraft boxes with a tuck or lock corner, 18oz to 46oz, for hot meals, rice dishes and street food.

Water-based dispersion Plastic-free claim supportable — covered by flustix FPPC025 on the water-based range.
PE (conventional) Conventional polyethylene barrier. Not part of any plastic-free claim.

Window and corrugated boxes

Corrugated board with a PET or PLA window — used where the product has to be visible without opening the pack.

PE (conventional) Conventional polyethylene barrier. Not part of any plastic-free claim.

A window makes the pack a multi-material item — it cannot be described as plastic-free even when the board is water-based coated.

Noodle boxes

Tall, narrow boxes for noodle and pasta takeaway, with a fold-in lid that vents steam and a base that stays rigid when loaded.

Water-based dispersion Plastic-free claim supportable — covered by flustix FPPC025 on the water-based range.
PE (conventional) Conventional polyethylene barrier. Not part of any plastic-free claim.

Compartment boxes

Divided trays that keep wet and dry components apart in one pack — the format behind most bento and set-menu delivery.

Compartment count and split ratio are set by the cutting die, so a change of layout means a new die.

Boxes and the grease barrier

Food-contact compliance for board boxes turns on the barrier, not the board.

Grease resistance is a tested property

Kit-test ratings and migration reports are different documents. A box can pass a grease-resistance test and still need a migration report for the coating in contact with fatty food.

Windows remove the plastic-free option

A board box with a PET window contains plastic. If a plastic-free claim matters, specify a paper window or a windowless design — the same box in two variants is two different claims.

Compartment trays are die-specific

The cutting die fixes the compartment count and split ratio. Changing the layout is a new die, which is why this format is usually quoted from a drawing rather than from a size table.

Three mistakes in box specifications

Choosing a box by litre capacity when the food’s fill height and moisture decide the format.
Adding a window after the plastic-free statement has been written into the artwork.
Assuming a heavier board solves leaking — the seam and the coating solve it, not the grammage.

Where this format is used

Rice and grilled food

Tuck-corner kraft boxes in 18oz to 46oz, water-based or PE barrier.

Bakery and retail

Corrugated boxes with a window where the product has to be seen.

Noodle delivery

Tall bodies with a fold-in lid that vents steam.

Bento and set menus

Divided trays keeping wet and dry components apart.

Questions buyers ask about this range

Can a kraft box be plastic-free and still hold a saucy dish?

A water-based dispersion can carry a plastic-free statement and is used on hot-fill articles, but the rated condition comes from the test report for that article. For very high-fat dishes a PE barrier is the more conservative choice.

Are the boxes microwaveable?

Depends on the barrier and the board. PE-lined boxes are commonly used in microwaves briefly; water-based coatings are not automatically rated for it. Ask for the temperature rating in writing rather than assuming.

Do you supply the box with a window in paper?

A paper window is possible on some formats and not others. It is a tooling question — send the pack size and we will confirm which formats can take one.
