Automatic Bag Filler

Automate your bag line with a stainless steel Form-Fill-Seal (FFS) machine that will take a 27 inch wide film, form it into an 8 inch diameter tube, seal the tube bottom and fill the sealed tube with 5-6 pounds of wet, mixed substrate. The result is a bag of from 18 to 20 inches long. The production rate is 8-12 bags per minute. The top of the bag remains partially open for spawning.

UnicornBags. will supply 2.5 mil PP or PE film already installed with a suitable filter patch for breathing.

Installation is free. If a turn-key system is purchased, service is free for 6 months. A contract to supply filtered film is necessary.

Each bag produced on this machine costs about 8 cents U.S. The price of the machine does not include shipping from Texas. An auger for filling the machine ($8,500) is not included.
