Big Bag / Jumbo Bag Filling Machine
Behpoo big bag filling machines fill FIBC bags from 250 to 2,500 kg with weighing accuracy down to ±0.1%. Five configurations are available, from economy semi-automatic stations to twin-station lines at 60 bags per hour.

A big bag filling machine fills flexible intermediate bulk containers with powders, granules and flakes to a defined target weight. The empty bag is suspended from its lifting loops, filled under weight control, then released for closing and palletising.

Behpoo supplies the full range — from manual stations for low-volume and frequently changing products, up to twin-station automatic lines for high-throughput mineral and chemical duty. Every machine can be specified with overhead or platform weighing, gravity, screw or air-assisted feed, and ATEX execution where combustible materials are handled.
In the line, the filler sits under a buffer hopper fed from silo storage through a rotary valve or slide gate, and discharges to bag closing, pallet conveying and stretch wrapping.
