Frequently Asked Questions
Is stainless steel better than plastic for daily use?
Stainless steel is generally the superior choice for longevity and safety. It does not retain food odors or stains, and it remains durable even if you drop it on a hard floor. Plastic can be lighter, but it often degrades or develops scratches over time. These small grooves can harbor bacteria, making stainless steel a more hygienic option for the long haul.
How do I know if a lunch box is truly leak proof?
Check if the product description mentions a silicone ring or gasket built into the lid. A simple press on lid is rarely enough to stop liquids from spilling. If you plan on packing soups or dressings, look for a box that specifically guarantees airtight performance. You can verify this by checking for sturdy locking mechanisms that create a vacuum like seal.
Can I put my glass lunch box in the microwave?
Most borosilicate glass containers are designed to handle thermal shock, meaning they can move from a cold fridge to a hot microwave. However, you must always remove the lid first. Plastic lids, even those labeled as microwave safe, can warp or release chemicals when exposed to high heat. It is much safer to warm your food without the cover in place.
Are there any specific plastics I should avoid?
You should stay away from older plastics or any containers marked with recycling code 7, which is a catch all category that often contains BPA. This material can be unpredictable regarding chemical stability. Instead, look for products labeled as polypropylene, which is generally considered one of the safer types of plastic for food contact. It is durable, heat resistant, and free from the most concerning endocrine disruptors.
How often should I replace my lunch box?
If you maintain your container well, a high quality stainless steel or glass box can last for several years. You only really need to replace it if the silicone seal becomes cracked or if the locking clips stop snapping shut properly. Plastic boxes usually show their age faster through scratches or discoloration. Once you notice the interior surface looking cloudy or worn, it is time to upgrade to a fresh container.
