Choosing truly leakproof rectangular food storage containers can be tricky, but knowing what to look for will make the process much easier. Here are the most important factors to consider:

• Seal Type: The seal is the most critical component of a leakproof container. Look for containers with silicone seals or gaskets that create a tight, airtight barrier. Rubber seals can also be effective, but they may degrade over time. Avoid containers with flimsy plastic seals that don't make a solid connection.

• Lid Locking Mechanism: The lid locking mechanism is what holds the seal in place and prevents it from being compromised. Snap-lock lids with multiple latches are generally the most secure. Screw-top lids can also be effective, but make sure the threads are deep and the lid fits snugly.

• Material: The material of the container itself also plays a role in its leakproof performance and durability.

  • Plastic: Plastic containers are lightweight and affordable, but they can be prone to staining and absorbing odors. Look for BPA-free plastic that's specifically designed for food storage. Tritan plastic is a popular choice because it's crystal-clear, durable, and stain-resistant.
  • Glass: Glass containers are more durable than plastic and won't stain or absorb odors. They're also oven-safe, making them ideal for meal prepping and reheating. However, glass containers are heavier and more fragile than plastic. Borosilicate glass is the most durable type and can withstand extreme temperatures.
  • Stainless Steel: Stainless steel is another durable and odor-resistant option. It's also lightweight and easy to clean. However, stainless steel containers aren't transparent, so you can't see what's inside without opening them.

• Ventilation: Some containers have built-in vents that allow steam to escape when microwaving. This can help prevent splatters and keep your food from getting soggy. If you plan to microwave your containers frequently, look for ones with ventilation.

• Size and Shape: Consider the types of food you'll be storing and choose containers that are appropriately sized. Rectangular containers are generally more space-efficient than round containers, but they may not be suitable for all types of food. Think of how you are trying to use your rectangular food storage containers.

• Dishwasher, Microwave, and Freezer Safety: Make sure the containers you choose are dishwasher, microwave, and freezer safe for easy cleaning and versatile use.

• Brand Reputation and Warranty: Research the brand and read reviews to learn about other customers' experiences. A good warranty can provide peace of mind if you experience any problems with the containers.

Even the best rectangular food storage containers require proper care to maintain their leakproof performance. Here are some tips:

• Wash thoroughly after each use: Food residue can degrade the seals and make them less effective. Wash your containers with hot, soapy water or place them in the dishwasher.
• Dry completely: Moisture can also damage the seals. Make sure your containers are completely dry before storing them.
• Avoid abrasive cleaners: Abrasive cleaners can scratch the plastic or glass and damage the seals. Use mild soap and a soft sponge or cloth.
• Store lids separately: Storing lids separately can help prevent them from becoming warped or damaged.
• Replace worn seals: If you notice that the seals on your containers are cracked, torn, or otherwise damaged, replace them as soon as possible. Many manufacturers sell replacement seals. In some cases the rectangular food storage containers themselves may be replaceable under warranty.
• Avoid overfilling: Overfilling containers can put undue pressure on the seals and cause them to leak.
• Don't use sharp objects: Don't use knives or other sharp objects to pry open lids, as this can damage the seals.
