When many customers inquire about custom non-woven bags, they do not know the difference between sewing and ultrasonic integrated non-woven bags. Friends who are in frequent contact may be more aware of the difference between the two, but the first contact must be a bit confusing. Then, let's take a look at the difference between sewn non-woven bags and ultrasonic integrated non-woven bags.
First of all, in terms of technology, the sewn non-woven bag needs the wire to be formed by flat sewing. The ultrasonic integrated non-woven bag does not use wire at all, nor does it use a sewing machine, just put the fabric on the machine, and it can be formed at one time.
Secondly, it can be seen from the above point that the artificial sewing is naturally much more expensive than the one-time molding price. Therefore, the sewing process non-woven bag is more expensive than the non-woven bag produced by the hot pressing process.
In terms of aesthetics, in fact, the integrated non-woven bag is much more beautiful than the sewn non-woven bag. Since the corner lines are automatically generated by the machine according to the mold, the specifications are relatively uniform, and there will be no broken seam joints and joints. Seam distortion. The one-piece non-woven bag has a relatively high cost performance.
In terms of production efficiency, today's machines can produce a product in a few seconds, while manual sewing of non-woven bags requires several processes and takes longer to produce a product. Therefore, if the customer orders a large amount of non-woven bags, it is recommended to make ultrasonic integrated non-woven bags. When mass-produced, the daily output will reach more than 50,000, and the cost of production is far lower than the cost of seams. , The production speed is higher than the sewing speed. At the same time, the handbag and the side line of the bag can be pressed with molds. The patterns are rich in variety, and the products are high-end and beautiful.
