KARAT EARTH Clamshell Take Out Food Containers 6x6 - Eco-Friendly Bulk

Our review of the KARAT EARTH Clamshell Take Out Food Containers finds them best for restaurants, caterers, and busy households that need sturdy, eco-conscious to-go packaging. The single biggest reason to buy is their blend of up to 50% minerals, which meaningfully reduces plastic use while delivering a durable, leak-resistant container suitable for hot or cold meals. These 6in x 6in clamshells arrive in a 400 count bulk pack and strike a solid balance between environmental intent and everyday practicality.

Key Features

• Eco-Conscious blend: The material mix contains up to 50% minerals, lowering plastic content and helping reduce environmental harm without sacrificing strength.
• Temperature versatility: Designed for both hot and cold foods, these clamshells maintain their shape with soups, curries, salads, and chilled sides.
• Leak and spill resistance: The mineral-filled construction and form factor handle oily and moist foods for mess-free transport.
• Stackable design: The clamshells nest securely for compact storage and easier transport, saving space in kitchens and delivery vans.
• Bulk value: Sold as 400 containers (100 per pack x 4 packs), the quantity suits foodservice use and offers per-unit cost savings for businesses.

Who It's For

The containers are aimed at small to mid-size food businesses, meal prep services, and busy households that want durable disposables with an eco-conscious angle. If you run a cafe, food truck, or cater events, the bulk 400 count and stackable format make inventory management straightforward and cost-effective.

Those who should look elsewhere include operators who require compostable certification or certified biodegradable claims beyond a mineral blend, and customers needing very tight locking lids for long-distance liquid transport, since some users report mixed lid closure feedback.

Pros & Cons

Pros

• High perceived quality and sturdiness that holds up with heavy, loaded meals.
• Good heat retention for hot dishes and stable shape at varying temperatures.
• Strong value in bulk packaging for restaurants and catering operations.
• Space-saving stackability eases storage in tight kitchens.

Cons
