What a takeout box has to do
A takeout box holds food from the pass to the customer's table, sometimes well after it leaves the kitchen and after a ride in a delivery bag. It has to keep its form with hot, wet or oily food, close firmly, stack in a bag, and often survive a reheat. It also has to meet the rules of the market it is sold in and fit the brand's claims about packaging. Plastic and paper boxes handle these jobs in different ways, so the comparison starts with the menu, not the material.
In this note plastic means PP, resin code 5, the default for hot takeout, and paper means paperboard boxes: kraft, white card and white card with a foil lining, made by paper packaging plants such as those around Longgang near Wenzhou. PET is covered separately in clear PET vs PP fruit boxes, because it is a cold display material.
PP boxes: strengths and limits
PP boxes are the workhorse for hot mains, soups and sauces. A partner plant in Huizhou, Guangdong, makes a rectangular series on a 170x115 mm footprint, from 500 ml at 34 mm deep and 17 g to 1,000 ml at 64 mm and 22 g, with roast-meat boxes on a 217x149 mm footprint at 1,200-1,500 ml. Round tubs reach 2,000 ml. One lid serves several depths, the snap fit can be checked in a standard tilt test, and the boxes can be reheated where the supplier marking allows it, usually with the lid removed or vented.
The limits are about perception and end of life. Plastic boxes face policy pressure in many markets, and some brands want to cut visible plastic. PP is widely accepted for recycling in some systems and not in others, so recycling wording depends on the market. PP boxes also nest tightly, which is a strength for freight, but they do not ship flat.
Paper boxes: strengths and limits
Paperboard boxes suit dry, bakery and fried food, and pizza. The reference range from a partner paper packaging plant includes kraft and white card bakery boxes with a clear lid at 190x85x35 mm, click-lock takeout boxes from 350 to 2,880 ml in kraft, white card or white card with a foil lining, some with two compartments, and pizza boxes from 6 to 12 inches. Paper boxes take full-colour print well, ship flat and are folded at the point of use, and they read as lower plastic content to many customers.
The limits are wet and hot food. Plain board softens with steam and oil, so grease resistance comes from a coating, a lining or a barrier layer, and that is where the rules start. In the United States, California AB 1200 has banned intentionally added PFAS in plant fibre food packaging since 1 January 2023, and at least 13 states restrict PFAS in food packaging in some form. A paper box is only as compliant as its barrier. Paper boxes with a lining are also not for the microwave unless the supplier says so for the exact item.
Side by side
| Factor | PP box | Paperboard box |
|---|---|---|
| Hot, wet and saucy food | Strong | Needs a barrier or lining |
| Reheating | Microwave use per supplier marking | Usually not, unless stated per item |
| Dry, fried and bakery food | Works, can trap steam | Strong |
| Lid print, labels or sleeves | Full-colour print on the box | |
| Freight | Nests, 200-300 sets per carton typical | Ships flat |
| Key rules | 21 CFR 177.1520, EU 10/2011, GB 4806.7 | US state PFAS rules, GB 4806.8, EU 1935/2004 |
| Reference model | 750 ml, 170x115x51 mm, 19.6 g | Bakery box 190x85x35 mm |
Cost drivers, without prices
The desk does not publish prices, but the cost drivers can be compared. For PP the main drivers are resin, gram weight and cycle time: a 19.6 g box uses more resin than a 17 g box, and a thinner wall costs less but can crack or warp. For paper the drivers are board grade, print colours, coatings or linings and die cutting. Freight changes the picture: PP boxes nest, paper boxes ship flat, and both are light and bulky, so cubic volume per carton often matters more than unit weight. Printed items carry their own minimums: typically 10,000-50,000 pieces per item for printed PP lids and 5,000-10,000 per design for printed paper boxes, confirmed in writing for each program. See what drives container costs.
Rules that decide the choice
In the European Union, the Single-Use Plastics Directive 2019/904 has banned single-use plastic cutlery, plates and expanded polystyrene food containers and cups since 3 July 2021; PP takeout boxes are not banned by it, but member states apply consumption-reduction measures and marking duties, so EU programs need a check with counsel. In the United States, PP containers sit under 21 CFR 174-178, while paper and fibre packaging sits under the same food contact rules plus state PFAS laws. In China, GB 4806.7-2023 covers plastics and GB 4806.8 covers paper. Any recyclable or compostable claim on either material has to follow the FTC Green Guides, 16 CFR 260. Confirm the final position with your test lab or counsel; the compliance guide lists the documents.
How each is tested
The test plan follows the material. PP boxes are checked for size and gram weight, lid fit and opening force, tilt and inversion with a liquid, drop, opening after freezing at -18 C, and a microwave heating test where the item is marked for it. Paper boxes are checked for burst and edge crush strength, print adhesion and rub resistance, grease hold-out on the barrier, and carton stacking. Migration tests run at a third-party lab against the target market's rules. The number of samples and the pass criteria are a stated working default, confirmed per order; see testing and inspection.
A practical split for most menus
- Hot mains, curries, soups and anything reheated: PP boxes and tubs.
- Fried food, burgers and sandwiches: paper click-lock boxes with a suitable barrier, or vented PP where steam is an issue.
- Bakery, desserts and gifts: paper boxes with a PET or PVC window, which is not heated.
- Pizza: paper boxes, 6 to 12 inches in the reference range.
Many programs end up mixed, and that is fine: the desk aligns lead times across the PP and paper plants and consolidates one shipment. Lead times are typically 7-15 days from stock and 15-30 days printed; see MOQ and lead time. Send the menu and target markets through the quote form, or start from takeaway packaging.
