Clamshell with grilled skewers and sides
Why kitchens switch to MFPP

The container that survives the drive home.

Holds heat, stays rigid

Mineral-filled PP keeps food hot longer than foam and does not sag when the lid is loaded.

Grease and cut resistant

Sauces, fried food and a knife in the box. No soak-through, no leaks in the bag.

One or three compartments

A single well for entrees and sandwiches, or three wells so sides never touch the main.

Stacks flat, ships dense

Nested cases take a fraction of the shelf space of foam, and the hinged lid closes with one hand.

Why clamshells

Foam is cheap until it leaks.

MFPP clamshells cost a little more per unit than foam and a lot less than a refund. They hold heat on delivery, take a microwave without warping, and the black version photographs like a plated meal.

Tested, not claimed

Built for the microwave, the freezer and the drive home.

Foam melts, paper soaks, thin plastic cracks. MFPP holds its shape at both ends of the temperature scale, which is why it is the container upscale delivery kitchens standardise on.

How every case is made
  1. Resin Polypropylene blended with mineral filler for rigidity and heat retention.
  2. Forming Base and lid are thermoformed as one hinged piece, so nothing separates in the bag.
  3. Testing Hot-fill, microwave and drop tests on every production run before it is cleared.
  4. Packing and dispatch Nested cases, sealed and shipped within 1 to 2 business days.
  5. Vented lids Steam vents for fried food that needs to stay crisp on delivery. 6" to 9" sizes, both layouts.

Questions

Everything owners ask about clamshells.

How many containers are in a box?

150 containers plus 100 free, so 250 in every box. Subscribe and we add 50 more to every delivery, 300 in total, plus 100 free stickers. Shipping is free on every order.

Is MFPP microwave safe?

Yes, for reheating. Mineral-filled polypropylene holds its shape in the microwave and the freezer, and it does not go soft with hot, oily food the way foam does.

Which sizes come with three compartments?

The 7", 8" and 9" squares, with a solid or vented lid. The 5", 6" and 9" x 6" x 3.5" boxes are single compartment. Every size comes in white and black at the same price.

Vented or solid lid?

Vented lids let steam out, so fries and fried food stay crisp on the way home. Solid lids keep the heat in for mains, rice and anything that should arrive hot. Every size comes in both, except the 5" x 5" and the 9" x 6" x 3.5", which come with a solid lid. Same price either way.
