FBH-32D Heavy-Duty Plastic Bag Automatic Heat-Sealing Machine

The FBH-32D Heavy-Duty Plastic Bag Automatic Heat-Sealing Machine is designed for automatic heat sealing of PE and PP film bags in industrial packaging applications. The machine processes the bag mouth through a sequential sealing system that can include bag-mouth cleaning, optional trimming, heat sealing, pressure compression, cooling and embossing. Its sealing section uses three heating blocks and one heat-dissipation block, while a PTFE sealing belt prevents direct contact between the heating blocks and the bag surface. This arrangement helps reduce sticking during heat sealing. After heating, the bag passes through pressure rollers and two cooling blocks before the embossing stage. The catalogue specifies a 7–12 m/min sealing speed, 8–10 mm sealing width, 0–400°C sealing temperature range, and compatibility with PE and PP film up to 1.0 mm thickness. The machine has a sealing height range of 750–1450 mm from the floor and a total power rating of 4 kW. This makes the FBH-32D particularly relevant for industrial packaging lines requiring automated closure of plastic film bags with a controlled multi-stage sealing process.
