We have two kinds of production process.
Heat pressure suture: With ultrasonic thermal pressure forming, bearing weight 2.5-4 kg. The advantage is that the style is novel and beautiful, the disadvantage is that the carrying capacity is limited, the bag amplitude is not too big.
Sewing: Using traditional manual sewing, the load weight is 5-7.5 kg. The advantage is that the bearing weight is a little stronger, the strength is strong, the disadvantage is the manual processing, unavoidable leakage of the needle, the line is not straight.
