Wholesale School Backpacks from China<\/h1>\n

School backpacks are bought by the thousand and judged by children, which makes the category unusually unforgiving. A strap that fails in October, a zip that jams when the bag is full of books, or a print that flakes off in the rain all become complaints long before the next school year.<\/p>\n

\"Navy The photograph shows a representative backpack from the category. Colour, trim and print follow the approved sample, and the image is illustrative rather than a picture of your goods.<\/p>\n

We have sourced school bags out of the Fujian and Zhejiang clusters for years, and the same three failures come back. A fabric sold at a denier that thins the moment the order grows. A shoulder strap sewn to a price rather than to a load, which lets go at the top anchor. And reflective trim that was decorative on the sample and absent from the bulk, which matters on any bag a child carries home in winter.<\/p>\n

This page covers what the fabric and hardware words mean, what belongs on the order sheet, and the checks that catch a weak lot. The supply towns behind the category are in our wholesale bags and luggage overview<\/a>.<\/p>\n

Fabric, straps and the parts children break first<\/h2>\n

The fabric is the specification that most affects the life of the bag, and denier is the number that describes it. Higher denier means a heavier yarn and a sturdier weave, which is what keeps a bag sitting upright when it is empty and stops the base wearing through on a floor. The denier belongs on the order sheet, and the bulk is checked by feel and by weighing a cut swatch.<\/p>\n

Backing is the second half of that story. A woven fabric is finished with a coating, and the coating decides whether the bag shrugs off a rain shower or soaks through. A polyurethane backing is the common middle ground; a thin coating saves weight and money and shows its limits in a wet season.<\/p>\n

The straps carry the load, and the weakest point is the top anchor rather than the webbing. Strap failures are almost always stitching failures, so the check is a pull test on a finished bulk bag, not an inspection of the sample.<\/p>\n

Zips and sliders are where a cheap bag feels cheap. Coil zips vary in size and in the quality of the slider, and a size or two down from the specification produces a bag that snags at the corners once it is fully loaded.<\/p>\n

Specifications and minimum order<\/h2>\n

Our minimum order is 1 piece, so you can start with a single unit and scale up once the sample is approved. Every line below changes what the factory sews. We do not print prices or schedules here, because fabric and hardware inputs move; send the sizes, the fabric and the quantity, and we come back with a live quotation and a firm production slot.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n

Minimums in sewn bags are driven by fabric dyeing and by the printing setup, which is why one colourway across a size range is the cheapest way to start. Our sourcing service<\/a> covers the factory screening, the sample round and the inspections below.<\/p>\n

What the fabric words mean in practice<\/h2>\n

Denier is a weight per length, so a higher number means a heavier yarn rather than a better fabric by itself. A high denier woven loosely is weaker than a moderate denier woven tightly, which is why the specification names the yarn and the weave together rather than a single figure.<\/p>\n

Water resistance is measured, not asserted. A coating keeps water out until the fabric is flexed enough to break the film, and a bag used daily will flex at the same folds. A simple shower test on a bulk bag, flexing the panel under running water, tells you more than any claim.<\/p>\n

Reflective trim has its own trap. Genuine retroreflective tape returns light to its source and shows up in a headlight; a decorative silver trim looks similar in daylight and does nothing at night. If a customer buys on visibility, the grade has to be named and checked with a torch.<\/p>\n
