When it comes to preserving food, many containers promise exceptional qualities like being leakproof, stainproof, or shatterproof. However, real-world testing often reveals that these claims fall short. Our team has rigorously evaluated numerous plastic, glass, and silicone storage sets over the years to identify those that genuinely offer superior performance. This extensive analysis ensures that only the most resilient and reliable options are recommended for storing leftovers, preparing meals in advance, and packing lunches, helping consumers avoid common disappointments.
Our assessment process for food storage containers involves a series of demanding trials designed to push each product to its limits. One crucial test is the 'drop test,' where glass containers are dropped empty from counter height to evaluate their shatter resistance, while plastic containers filled with water are repeatedly dropped to check lid security and integrity. This often leads to messy but informative outcomes, revealing true durability. The 'drip test' further examines leak resistance by filling containers with water and vigorously shaking them over a dry surface to observe any spillage, ensuring seals are truly airtight.
Another vital part of our evaluation is the 'stain test.' For this, a potent 'stain soup'—a mixture of garlic tomato sauce and ground turmeric—is used to fill each container. These are then stored upside down in a refrigerator overnight, microwaved, rinsed, run through a dishwasher, and finally hand-washed. At each stage, the containers are inspected for any lingering odors or discoloration, providing a clear picture of their stain and smell resistance.
Among the standout glass containers, Snapware Total Solution sets receive high praise. Their plastic latching lids provide an exceptional airtight seal, preventing any liquid escape even under vigorous shaking. The fixed silicone gasket simplifies cleaning, and the containers are both stackable when full and nestable for efficient storage. While contemporary Pyrex glass, made from soda lime, differs from older borosilicate versions, it offers enhanced impact resistance, a valuable trait for food storage applications.
For plastic options, the Joseph Joseph Nest Lock containers have proven to be remarkably robust. Their colorful lids remain secure and leak-free even after multiple drops from counter height onto a hard kitchen floor, a challenge many other plastic containers fail. These sets also feature a clever nesting design that creates a visually appealing and space-saving chromatic gradient when stored. Although some minor discoloration from the 'stain soup' was observed, it was minimal, and their overall toughness and aesthetic appeal make them a top choice.
In the silicone category, Anyday Anydeli Containers have emerged as a favorite. They cleverly mimic the design of traditional deli containers but are crafted from durable, microwave- and dishwasher-safe silicone. Despite silicone's reputation for less-than-perfect seals, these containers impressed with their ability to withstand significant squeezing and shaking without leaking, making them suitable for commuting. The integrated stainless steel rim adds structural integrity, and volumetric measurements enhance their utility for meal preparation. While silicone can retain stains and odors, this is a material characteristic rather than a flaw unique to this product, and its practical shapes are a significant advantage.
Our selection criteria for the best food storage containers focus on several key aspects, including functionality, temperature tolerance, quality materials, variety of sizes, and ease of storage. We prioritize containers that offer reliable leakproof and airtight seals, suitable for leftovers, meal prep, and packed lunches. Temperature tolerance is especially important for glass containers, which should be oven, freezer, and microwave safe. For plastic components, we look for durable, BPA-free materials and secure, easy-to-use latches. The availability of various sizes and shapes, as well as efficient stacking and nesting capabilities, also plays a significant role in our recommendations, ensuring that the chosen containers meet a wide range of kitchen needs and storage solutions.
