Frequently Asked Questions (FAQ)

Q1: Is this large-capacity picnic bag completely leakproof?
           A1: Yes. The interior storage compartment is lined with advanced food-grade material and welded using high-frequency seamless hot-pressing technology. This guarantees a 100% leakproof interior that easily contains liquid messes, sauces, or melted ice water.

Q2: How long can this thermal bag keep food hot or cold?
           A2: Designed with a high-density thick insulating foam interlayer, the bag effectively slows down heat transfer to lock in temperatures for up to 8 hours. It keeps your prepped meals warm or beverages cold efficiently. Adding reusable ice packs or ice bricks will significantly boost cold storage performance beyond 8 hours.

Q3: What are the exact dimensions of this bag, and will standard rectangular meal boxes fit flat inside?
           A3: The exact product dimensions are 24 x 14 x 18 cm. This bag features an extra-wide rectangular flat base measuring 24 cm in length and 14 cm in width, which is specifically tailored for stacking multiple bento containers, wide meal-prep trays, or fruit bowls side-by-side without tilting or flipping over.

Q4: What are the side metal D-rings used for?
           A4: The reinforced metal D-rings on the left and right sides are built to attach an adjustable shoulder strap (available for OEM customization). This provides ultimate flexibility, allowing users to switch from a hand tote to a comfortable hands-free shoulder bag.

Q5: How do I clean this picnic bag?
           A5: Maintenance is incredibly simple. Any accidental soup spills or food stains on the interior lining can be wiped away instantly with a damp cloth or sponge. The water-resistant outer fabric can be spot cleaned similarly. We do not recommend machine washing.

Q6: Are the internal insulation materials safe for direct food contact?
           A6: Yes. All internal components are 100% non-toxic, BPA-free, and fully compliant with FDA and LFGB international food safety standards. It is completely safe for packing sandwiches, raw fruits, and snacks directly inside without worry.

Q7: Will the bag have a distinct synthetic smell when brand new?
           A7: We strictly use premium, environmentally conscious textiles. Like any factory-fresh piece of luggage, a very faint new-fabric scent may be noticed initially. Simply unzip the main lid fully and allow it to air out in a well-ventilated space for 1 to 2 days before first use.
