Travel Backpack Construction and Waterproof Ratings for B2B Buyers
A travel backpack built for commercial buyers must balance carry-on compliance, fabric density, and waterproof performance. Our collection includes three models that cover distinct use cases. The BB-4502 is an IATA carry-on travel backpack in nylon at 0.9 kg with anti-theft detailing. The BB-5051 is a hybrid duffle-backpack with a shoe compartment and wet bag. The BB-4539 is a 24L PU leather backpack for buyers who need a more formal finish. All three are produced in our BSCI-certified facility with 50+ automated production lines and 150,000 units monthly output.
Waterproofing is specified at two levels. PU or PVC coating achieves 3000 mm+ hydrostatic head, suitable for daily commuting and light rain. TPU lamination reaches 10,000 mm+, the option to specify for buyers sourcing waterproof backpacks for harsher conditions. Fabric options include nylon at 110-160, 180-220 (420D), and 240-280 (600D) g/m2, polyester at 190T, 210T, 300T, 600D, and 1200D, and canvas at 8, 10, 12, or 15 oz. rPET is available for buyers with recycled material requirements.
Carry-On Sizing and Sourcing Specifications
The IATA carry-on guideline is 40x30x20 cm. The BB-4502 is designed within this envelope, which matters for retail buyers selling to frequent flyers. Capacity classes across the collection run 10-20L, 20-35L, and 35L+. For laptop compartments, we cut sleeves to 13 inch (30x22x8 cm), 15 inch (35x25x10 cm), and 17 inch (40x30x12 cm) internal dimensions.
