The Collapse-It container set is manufactured from high-grade 100% food-grade silicone, which maintains its flexibility across a wide temperature range from -40°F to 450°F. This makes the containers suitable for the freezer, microwave, and even the oven when the lids are removed. The collapsible design allows for a 60% reduction in vertical footprint, which is a practical benefit for RV living or crowded kitchen cabinets. The lid uses a four-way locking tab system with a rigid Polypropylene rim to help ensure a secure seal.
Specifications show the silicone thickness ranges from 1.5mm to 2.0mm, providing more thermal resistance than many budget alternatives. However, because silicone is naturally flexible, the containers can "telescope" or partially collapse if downward pressure is applied while the lid is off. To help maintain the appearance of the containers, it is helpful to know that high-acidity foods like tomato sauce can sometimes stain the silicone; applying a light coat of oil before use can help mitigate this.
- Use the circular gasket design to help prevent leaks during meal prep or travel.
- Hand wash or use a dishwasher, noting that silicone may retain strong odors like garlic.
- Monitor the locking tabs for whitening over time, which indicates material stress.
These containers are built to handle daily household use and offer a significant space-saving advantage. They are particularly useful for those who need to transition food directly from storage to heating in a single vessel.
If you need a larger, basket-style container for hauling more than just individual meals, the SAMMART 19L tub provides greater volume for household tasks.
