Storage of plastics at low temperatures has been proposed as a low-cost, lowmaintenance technique. The research described here concerned the results of cooling thin- and thick-walled (greater than 10 mm) plastics materials. Tinytalk loggers were used to record temperature proﬁles during cooling from ambient. Methylene blue powder was used to indicate the formation of condensation. Dimensional changes were determined on cooling. Thinwalled plastics may be safely placed in freezers protected only by a closed polyethylene bag. The same approach cannot be applied to thick-walled plastics, particularly those containing plasticized PVC because of large dimensional changes and formation of condensation.
