The implementation of fully automated production functions has improved workers' work efficiency and saved a significant amount of labor costs. The working principle of Guangzhou heat shrink packaging machine: using film constant temperature heat sealing technology, the seal is clear and firm. The sealing rapid cooling structure ensures higher sealing strength under high-speed production conditions. Adopting PLC program for automatic loop control, the performance is stable and reliable. Imported guide rod cylinder ensures precise movement Durable and long-lasting. Induction switch controls the film feeding system, reliably regulates the film feeding length, and reduces losses.
