The fully automatic L-type vertical sealing and shrinking machine is an upgraded version of the standard L-type sealing and shrinking machine, specifically designed for sealing and shrinking tall or thin products. It automates the entire process—including feeding, film sleeving, sealing/cutting, and shrinking—while ensuring the seal line remains centered. Capable of an output of 15–40 packs per minute, it is compatible with POF and cross-linked films, features automatic film blowing, and produces fine, neat seal lines. Widely used in the cosmetics industry, this machine is also suitable for sectors such as printing, color box packaging, household chemicals, automotive parts, hardware, and food.
