Custom container sizes and shapes
- Seamless, molded, expanded polystyrene foam insulation - for efficient, cost-effective temperature maintenance. This material is non-deteriorating, vapor-proof, leak resistant, and non-settling.
- Thick-walled containers with tight-fitting plug lids - for superior temperature retention.
- Reduced shipping costs due to lowered requirements for dry ice or refrigerants. Efficient insulating K factor of .19 remains unchanged throughout the long life of these containers. In independent tests, the rate of dry ice sublimation from these containers was approximately 3 Ibs. per 24 hours.
- Over 50 stock sizes to fit every need - Offered with or without exterior cartons.
You may need an insulated container with specific features not shown among the stock sizes listed. Let our engineers design the container right for your specific needs. Also available: foam sheets cut to your specifications, to be assembled into stock or custom cartons.

Independent tests prove insulation quality
Lab tests in which 36 half-gallon bricks of ice cream were placed in insulated container Model 50FW without dry ice showed the time required for a 10 degree rise in food temperature was 22 hours. Tests in which 35 half-gallon bricks of ice cream were placed in the insulated container (50 FW) together with 5 lbs. of dry ice showed the time required for a 10 degree rise in food temperature was 39 hours. The ambient temperature during both tests was 78°F.
