Many customers are not clear about the difference between sewing and ultrasonic one-piece non-woven bags when consulting about custom-made Non-woven Shopping Bag. Of course, this varies from person to person. Friends who often contact may be clearer, and those who contact for the first time must be a little confused.

First of all, from the perspective of technology, sewn non-woven bags require wires to be sewn into shape through flat sewing. Ultrasonic one-piece non-woven bags do not require wires or sewing machines at all. The fabric is directly put on the machine and it is OK to form it in one go.

Secondly, from the above point of view, it can be seen that manual sewing is naturally much more expensive than one-time molding. In today's era, labor wages are a major pain point for our industries with low profits. Therefore, it is natural that sewing technology is more expensive than voltage technology. Many customers want sewn products, but they want the price of voltage. It is not so good to have both fish and bear's paw.

In terms of beauty, one-piece bags are actually much more beautiful than sewn bags. 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 thread joints and crooked seams. Of course, this kind of beauty is based on the price. Only when the price is beautiful, will the product be considered beautiful. In other words, the product has a higher cost-effectiveness.

In terms of production efficiency, today's machines can produce a product in a few seconds, while manually sewn non-woven bags require several processes and take longer to produce a product. Therefore, if the customer orders a large number of non-woven bags, it is recommended to make ultrasonic one-piece non-woven bags. When mass-produced, the daily output reaches more than 50,000. The production cost is much lower than the cost of sewing, and the production speed is higher than the sewing speed. At the same time, the patterns of the handbags and the side lines of the bags can be pressed by molds, and the patterns are rich in variety, making the products look high-end and beautiful.
