Frequently Asked Questions (FAQ)

Q1: Is this lunch bag completely leakproof?
           A1: Yes. The interior lining is made of premium PEVA material and constructed using high-frequency heat-pressing technology. This seamless design ensures 100% leakproof performance, even when handling melted ice.

Q2: How long can it keep food cold or warm?
           A2: Equipped with a built-in thick EPE foam interlayer, it effectively isolates temperatures to keep your meals or drinks fresh, cold, or warm for up to 8 hours. Using an ice pack will yield even better results for cold storage.

Q3: How do I clean this lunch bag?
           A3: Cleaning is effortless. Both the water-resistant outer fabric and the food-grade inner lining can be easily wiped clean with a damp cloth or sponge. Machine washing is not recommended to preserve the thermal structure.

Q4: Can it fit a standard-sized lunch box?
           A4: Yes. The adjustable roll-top design provides flexible vertical space. When rolled down, it easily fits standard daily lunch containers(Length 17–20 cm × Width 12–15 cm × Height 5–7 cm) or up to 6 standard 330ml soda cans.

Q5: Are the internal materials safe for direct food contact?
           A5: Absolutely. The inner lining is made of eco-friendly, food-grade PEVA material. It is 100% BPA-free and complies fully with FDA and LFGB safety standards, making it completely safe for storing your food and fruits.

Q6: Is the shoulder strap adjustable and detachable?
           A6: The shoulder strap is fully adjustable to fit different body types comfortably for cross-body or over-the-shoulder carrying. While it is securely stitched for heavy-duty durability rather than detachable, it can be tucked away neatly when using the top handle.

Q7: Will the bag have a strong plastic smell when new?
           A7: All our materials are eco-friendly and non-toxic. Like any newly manufactured product, there might be a slight, harmless new-material scent initially. Simply open the bag and let it air out in a well-ventilated area for 1-2 days before first use.
