制袋机类别的区分及其制袋过程的设置要求：制袋机中有热切制袋机和冷切制袋机之分，它们的区别主要在后一刀的处理方法，但实际上都属于制袋机中的一种。共同点也相当明显，都是使用筒料来生产的，切袋之前都会有热封流程，都可以生产背心袋。热封热切制袋机需要先热封一刀，然后再热切切断，切后的边是热封住的，制好的背心袋更有保障，一般超市里用的都是是热封热切的背心袋。而热封冷切制袋机是先热封一刀，然后用冷刀切断，切后的边是开口的。它除了能用于背心袋生产外,制袋机把双线封刀换成单线封刀，也能用于平口袋的生产，因为它的切边是开口式的。相比较而言，热切制袋机更加适合对塑料纤维类、化纤类材料的热切，机器通过电加热切刀，热切后切口会自动封住不散。
The classification of bag making machine and the setting requirements of bag making process: there are two kinds of bag making machines: the hot bag making machine and the cold cutting bag making machine. Their differences are mainly in the processing method of the last knife, but they are actually one of the bag making machines. The common points are also quite obvious. They are all produced with cylinder materials. Before bag cutting, there will be a heat sealing process and vest bags can be produced. The heat sealing and hot bag making machine needs to heat seal a knife first, and then cut it off. The cut edge is heat sealed, and the made vest bag is more secure. Generally, the supermarket uses the heat sealing and hot vest bag. And the heat sealing cold cutting bag making machine is to heat seal a knife first, then cut with the cold knife, and the cut edge is open. In addition to the production of vest bags, the bag making machine can change the double line sealing knife into the single line sealing knife, and also can be used for the production of flat bags, because its cutting edge is open-ended. In comparison, the hot-air bag making machine is more suitable for the hot-air cutting of plastic fiber and chemical fiber materials. The machine will automatically seal the cut after the hot-air cutting through electric heating.
