1. First, confirm the weight of the non-woven fabric, such as 80g, 90g, or 100g (beware of merchants misrepresenting the weight on the fabric label).
2. Calculate the non-woven fabric weight using the formula: Length * Width * Weight * Tons(40g * 30g * 80g * 12300g / 1 ton)
3. Printing calculation: It's best to avoid screen printing on non-woven bags, as it's cheaper but not environmentally friendly. Generally, single-color printing costs around 0.8-1.5g, while two-color printing costs twice.
4. Manufacturing processes include ultrasonic heat sealing and stitching. Ultrasonic heat sealing costs less than 1 cent, while stitching costs around 3 cents. This allows you to calculate the price of a single-woven bag.
