The Best Collapsible Lunch Containers

Here are some of our favorite collapsible containers that are perfect for taking your food on the go.

1. Keweis Silicone Lunch Box

These high-quality food-grade silicone lunch containers are eco-friendly, non-toxic, SGS, and LFGB certified.

The material used for this container is much safer than general plastic. Additionally, it’s microwave, oven, refrigerator, freezer, and dishwasher safe.

This container comes in three different sizes. The smallest one is 350ml and is most suitable for nuts and candy. The medium-sized container is 550ml and can hold fruit or cake. The 850ml container (large) is perfect for sandwiches, salads, or meal prep.

These boxes also have valves to prevent hot gas and water vapor from building up in the boxes. However, it’s vital to note that when using the microwave or oven, this valve needs to be open. However, soups and salad dressings might leak through the valve.

You can fold this container to a thickness of 1.2 inches, which saves more than 60% of your kitchen storage space. It also makes them much easier to pack up and take home after eating the food you’ve packed.

The Keweis silicone lunch box can also withstand a 1.3 tonne car driving over it and it has passed a 60 meter drop test.

The set also includes two small boxes (350ml) and one large box (1200ml). FLEX&LOCK has made these containers BPA-free.

4. Drying-Natural Collapsible Food Storage Container

One of the issues with plastic or silicone containers is that they sometimes stain. The benefit of this container is that it’s stain resistant. Additionally, it’s also dishwasher and freezer-safe. There are four sizes available; 300ml,600ml,750ml and 1000ml.

This container has been laboratory tested and can withstand 7000 folds. This means that it’s durable and can be used for a long time. Furthermore, it’s leak-proof.

The Drying-Natural container is BPA-free, making it non-toxic, non-stick, and easy to clean. The reason for the container’s durability is that it’s made of polypropylene and thermoplastic elastomers (TPE). TPE is stronger than silicone which aids the container in keeping its shape.


  • BPA free
  • Easy to clean
  • Microwave, dishwasher and freezer safe
  • Can withstand 7000 folds
  • Durable
  • Stain resistant
  • Leak proof


  • Susceptible to thermal expansion. Therefore, not recommended for long-term storage of hot liquids.

How to Choose the Right Collapsible Lunch Container

If you decide that you need a lunch container, you should keep these factors in mind:


Your daily routine and eating habits will impact the size of the lunch container you need. Those who have smaller appetites might be satisfied with a medium sized lunch box. On the other hand, people with longer work days might need larger containers.


Some lunch boxes have additional features. For example, some lunch boxes have insulation properties, or come with utensils. If you need your food to maintain its temperature, checking the properties of the container is essential.


Some containers are easier to damage or break while others have been drop tested and designed to withstand multiple folds.


The container’s material often has a large impact on the properties of the container. It’s also important to ensure that the container is food safe and non-toxic.

Additionally, if you’re worried about your environmental foot-print, there are many lunch containers that use environmentally friendly materials.

It’s also important to note that not all containers are made using dishwasher, microwave, oven and refrigerator safe materials. This is an important factor to consider before making a purchase.


Different containers have different levels of compactness. Some containers collapse to one-third of their erect size while others only collapse to half their erect size. This might be an issue for people with limited storage space.


In conclusion, food containers have become a staple and can be used for both children and adults. However, they can take up a lot of space both in your kitchen and the bag used to carry them. Collapsible lunch boxes enable users to make the most of their storage space.
