It All Starts with the Material: Not All Silicone is the Same
This is the most important factor. The quality of the silicone determines its safety, durability, and performance.
Platinum-Cured Silicone vs. Regular Silicone
You'll see these two main types on the market. While both are generally safe, there's a clear winner for quality.
•Regular Food-Grade Silicone: This is the standard. It's made using a peroxide-curing process. It's safe for food contact but can sometimes contain fillers or byproducts that might lead to a slight odor or affect the taste over time.
•Platinum-Cured Silicone: This is the gold standard. It uses a platinum-curing process that results in a purer, more stable, and more durable final product. There are no fillers, no byproducts, and absolutely no taste or odor. It's the highest quality silicone you can get.
Pro Tip: The Pinch Test How can you tell if a product has fillers? Pinch and twist a flat part of the silicone. If it turns white, it likely contains fillers. Pure, high-quality silicone (like the kind SUNOVA LIVING uses) will retain its color.
Decoding Food Safety: What Those Labels Mean
When you're putting food in a container, safety is non-negotiable. Look for these key certifications.
FDA-Approved and LFGB-Certified
These are the two main food-contact safety standards.
•FDA (U.S. Food and Drug Administration): This is the standard in the United States. It ensures the silicone is safe for use with food.
•LFGB (Lebensmittel-, Bedarfsgegenstände- und Futtermittelgesetzbuch): This is the German and European standard. It's generally considered to be even stricter than the FDA standard, with more rigorous testing. All SUNOVA LIVING products meet both FDA and LFGB standards.
Always Look for "BPA-Free"
BPA (Bisphenol A) is a chemical found in some plastics that can be harmful to your health. While silicone is naturally BPA-free, always double-check for this label to ensure you're buying from a reputable brand that doesn't use any plastic additives.
Features That Make a Difference
Once you've confirmed the quality and safety, it's time to think about how you'll use your lunch box.
•Leak-Proof Lids: This is a must if you plan on packing anything with liquid, like soups, yogurt, or dressings. Look for lids with a secure, airtight seal.
•Compartments: Do you like to keep your food separate? A bento-style box with multiple compartments is a game-changer.
•Collapsibility: If you're short on storage space or want to save room in your bag after lunch, a collapsible design is a brilliant feature.
•Microwave, Dishwasher, and Freezer Safe: The best part about silicone is its versatility. Make sure the product is explicitly labeled as safe for all three for maximum convenience.
