Impression personnalisée en gros sac thermique non tissé Portable Eco petit sac isotherme avec logo

Q1: How does the bag keep food hot and cold?

The insulation comes from an EPE (expanded polyethylene) foam layer bonded with an aluminium reflective film between the non-woven outer and polyester inner shells. The aluminium film reflects radiant heat back toward the food, while the EPE foam slows conductive transfer, so hot dishes stay warm and chilled items like seafood or bubble tea stay cool without power or ice packs. Because thickness is customizable, you can tune the barrier for short urban trips or longer holds. The result is passive, reusable temperature control that protects food quality from kitchen to doorstep on every delivery run.

Q2: Is the non-woven material food-safe and easy to clean?

Yes. The bag uses food-grade, FSC-certified non-woven fabric with a polyester and aluminium lining that does not leach odors or taste into food, so it is safe for direct contact with meals and drinks. The smooth inner surface wipes clean with a damp cloth between runs, and the fabric resists tearing better than thin film alternatives. Because the build is non-absorbent, spills stay on the surface rather than soaking in, which helps meet hygiene expectations for repeated delivery use. For brands prioritizing sustainability, the certified material supports a greener packaging story without sacrificing the durability needed for daily food transport.

Q3: How should I choose the size and insulation thickness?

Start with what you carry most: small pouches suit milk tea and side sauces, mid-size bags fit lunch sets and single mains, and large totes handle seafood combos or family orders. For insulation, a standard EPE thickness holds temperature well on short urban trips, while a thicker custom layer extends the hold for longer routes or hot dishes that cool fast. Match the closure and sidewall rigidity to how the bag is carried—by hand, in a delivery box, or in a rider's backpack. Because every dimension and thickness is made to order, you can standardize one specification across your menu or run a few sizes for different dayparts.

Q4: How durable is the bag for daily delivery use?

Built for repeat use, the non-woven shell resists tearing and abrasion far better than thin plastic film, and the bonded EPE and aluminium layers keep their shape through daily folding, loading, and wiping. Prints are cured to resist cracking and fading, so branding stays legible after weeks of handling. The seams and closure are reinforced for the open-close cycle of real delivery shifts, not one-off use. To extend life, empty and air-dry the bag after spills and avoid prolonged direct sunlight, which can fatigue any fabric over time. With basic care, a single bag supports hundreds of trips, lowering cost per delivery versus disposable packaging.
