FBH-42D Heavy-Duty Automatic Plastic Bag Heat Sealing Machine

The FBH-42D Heavy-Duty Automatic Plastic Bag Heat Sealing Machine is designed for automated sealing of PE and PP film bags. Its working process combines bag-mouth cleaning, optional trimming, multi-stage heat sealing, pressure roller compression, cooling and embossing. The sealing section uses four heating blocks and one cooling/heat-dissipation block. PTFE sealing belts prevent direct contact between the heating blocks and the bag surface, helping reduce sticking during the sealing process. After heat sealing, the bag mouth is compressed through pressure rollers, cooled using two cooling blocks and then embossed. The catalogue specifies a 7–12 m/min sealing speed, 8–10 mm sealing width, 0–400°C temperature range, and compatibility with PE and PP film up to 1.0 mm thickness. The sealing height is adjustable from 800–1700 mm from the floor, with a total power rating of 5.5 kW. The model is therefore suited to industrial packaging operations where automatic plastic-bag closure requires a controlled sequence from heating through cooling and final embossing.
