Plastic bag sealer for polyethylene bags
Achieve consistent hermetic sealing of polyethylene bags while preserving the integrity of high-value and oxygen-sensitive powders with this reliable heat-sealing system, essential for maintaining product quality during storage and transit.

Seals Polyethylene Bags in Bulk Packaging
The IS-850 from GEA is a pneumatically controlled impulse sealer designed for efficiently sealing polyethylene bags in bulk packaging applications. Featuring an extruded aluminum frame, it delivers precise temperature and sealing time control via an integrated seal control unit, ensuring reliable hermetic seals. Ideal for food, dairy, nutraceutical, and chemical industries, the IS-850 is suited for handling high-value powders, such as protein powders and oxygen-sensitive ingredients like infant formula. Capable of manual or semi-automatic operation, the sealer integrates seamlessly into production lines, providing flexibility with horizontal and vertical mounting options. For enhanced compatibility and longevity, the IS-850 is engineered to maintain constant sealing pressure, and its design allows for easy cleaning and maintenance. Additionally, GEA offers sample testing support to optimize sealing performance for various bag materials.
