Lid, material, size and shape are all factors used to determine which microwave safe containers to purchase. So how do you decide which microwaveable containers are best for meal prep, storage and reheating food?
Well, there are a few key factors to consider when selecting microwavable containers for food. Aside from the being microwave safe, here are some important factors to think about:
Size: Portion control is a primary necessity in meal prep. The size needs to be adequate to nourish your needs, but not be too abundant that you end up overeating. However, sometimes its necessary to have a range of sizes to accommodate various meal prep essentials.
Material: Glass does not stain, absorb odors or harbor flavors. Therefore, it seems to be the best material choice in this situation. In hindsight, plastic lids don’t rust and plastic containers don’t shatter.
Lid: The lid must be food grade, rust-free and also needs to lock in place. Snap-on lids with airtight locking are also a benefit. Plastic lids are rust-free and are fairly durable over time.
Shape: Round, square or rectangular are determined by your storage space and personal preference. However, dual compartment separation is nice to keep meal prep items divided while still remaining in the same microwave safe container.
