1、 Equipment Overview
The non-woven single pass vest bag making machine is designed specifically for producing high-quality, thick non-woven vest bags. Its "single pass" design means that the equipment performs high-precision processing on a single production line. Compared to multi pass equipment, it exhibits stronger stability and sealing strength when processing thick non-woven fabrics weighing 50-100 grams per square meter (gsm)
2、 Core working principle: Ultrasonic welding
(1):High frequency vibration: The ultrasonic generator converts electrical energy into high-frequency mechanical vibration.
(2):Molecular friction: The vibration is transmitted to the non-woven fabric contact surface through the welding head, causing intense friction between material molecules.
(3):Instant Fusion: The heat generated by friction instantly reaches the melting point of the material, causing the two layers of non-woven fabric to fuse together under pressure.
(4):Cooling forming: After the vibration stops, the material cools and solidifies under pressure, forming a high-strength weld seam.
3、Application advantages
(1):Environmentally friendly and efficient: No need for needle and thread, saving manual labor for frequent thread changes, and the finished bags can be recycled, in line with the global trend of plastic reduction.
(2):High sealing strength: The ultrasonic welding strength is close to the strength of the material itself, and the load-bearing capacity far exceeds that of ordinary plastic bags.
(3):Multifunctionality: Some high-end single pass models can produce various bag types such as flat pockets and D-cut bags (hand-held bags) by replacing molds.
(4):Easy to operate: highly automated, one skilled worker can operate 2-3 devices.
4、summary
The non-woven single pass vest bag making machine is an ideal choice for producing environmentally friendly shopping bags. With increasingly strict restrictions on disposable plastic products worldwide, non-woven bags produced using ultrasonic technology are becoming the preferred choice for supermarkets, clothing stores, and gift packaging. Its stable single pass production mode ensures that every bag meets the export grade quality standards.
