4. FAQ – Food Containers
Q1: Are these containers food-grade and BPA-free?
A: Yes. The food containers are made of food-grade plastic, suitable for direct contact with food. They are safe for cold storage and typical household use.
Q2: Can the containers be used in microwave or dishwasher?
A: Regular containers are generally microwave and dishwasher safe (lid removed for microwave). For high-temperature or professional use, please confirm exact material and temperature range per model.
Q3: What is the difference between regular and double-lock containers?
A: Double-lock boxes feature two-sided locking clips and often better sealing performance, making them ideal for liquid foods, soups, or transport scenarios where leakage prevention is important.
Q4: Are the Double-Buckle containers truly airtight and leak-proof?
A: Yes. The Double-Buckle series features a secure locking mechanism on the lid, typically combined with a silicone seal, which provides a strong, airtight, and leak-proof barrier. This makes them ideal for storing liquids, sauces, and highly perishable items.
Q5: Can these containers be used in the freezer and microwave?
A: While the specific material (PP or PC) determines exact temperature resistance, these commercial-grade containers are generally designed to be freezer-safe. The lids should typically be removed or vented when microwaving to prevent pressure buildup. Always check the specific material code on the product for detailed temperature guidelines.
Q6: How do the different series (A, B, 800, 500, 300) relate to each other? A: The different series numbers usually denote variations in shape, depth, or locking mechanism:
- A/AA/AAA/B Series: Standard lids, often used for stacking and general dry/refrigerated storage.
- 800 Series: Tends to be deeper or have unique dimensions.
- 500 & 300 Series (Double-Buckle): Feature the secure locking clips for superior airtight performance. The 300 series generally indicates deeper containers than the 500 series.
