Features of Silicone Lunch Box

1. Safety Features: Non-Toxic & Food-Grade (Core Advantage)

• Food-Grade Material Certification: Qualified silicone lunch boxes are made of food-grade silicone(usually medical-grade or food-contact-grade) and comply with international safety standards such as the U.S. FDA (Food and Drug Administration) and the European LFGB (Lebensmittel-, Bedarfsgegenstände- und Futtermittelgesetzbuch). These certifications ensure the material is BPA-free, phthalate-free, lead-free, and non-toxic—no harmful chemicals leach into food, even when heated in the microwave or stored in the freezer.
• No Sharp Edges or Fragments: Unlike glass, ceramic, or hard plastic boxes (which may crack into sharp shards if dropped), silicone is soft and elastic. Its body and lid are designed with rounded edges, eliminating the risk of scratches or cuts (especially safe for children to use independently).
• Resistant to Food Contamination: Silicone has a smooth, non-porous surface that does not absorb food residues, oils, or odors. For example, it won’t retain the smell of garlic, curry, or pickles after cleaning—avoiding cross-contamination between different foods (a common issue with porous plastic containers).

2. Temperature Resistance: Adaptable to Extreme Environments

• High-Temperature Resistance: Food-grade silicone can generally withstand temperatures ranging from -40℃ to 230℃ (some high-quality models even up to 250℃). This means it can be directly placed in the microwave for heating (e.g., reheating leftovers) or used to hold hot foods (e.g., 刚 - cooked soups, steamed rice) without melting, deforming, or releasing toxic substances. Unlike low-quality plastic boxes (which may warp or leach chemicals at high temperatures), silicone remains stable.
• Low-Temperature Resistance: It also performs well in cold environments—silicone lunch boxes can be stored in the freezer for long periods (e.g., freezing pre-portioned baby food or meal-prep portions) without becoming brittle or cracking. When frozen food needs to be taken out, the silicone can be gently twisted to easily release the food (a feature that glass or hard plastic containers lack).
