crown Silo Bags
Crown Silo Bags are made of a seven-layers of Blown extruded technology with various polymers to achieve the best quality Silo Bags (Polyethylene) about 180-250 micron.
Images used are for representative purpose only.
The diameter of 8-10 feet and Length of 60 m, 75 m up to 90 m can be produced. Every Bag is folded with an automatic folding machine.
The outer layer is white with UV protective coating while the inner layer in contact with the grain is black.
Applications of crown silo Bags
Ideal for storing all kinds of grains, dried fruits, fertilizers, fodder, and other stuff.
Sealed immediately after filling up, trapping the oxygen that’s used up by the grains and produces carbon dioxide. The anaerobic condition prevents the formation of fungus or insects in the bags
Special machines are used to load and unload grains and other products from these bags.
Advantages of crown silo Bags
Retains original quality and quantity of the products
Ideal for long term storage
Perfect sealing and anaerobic conditions expel insects and fungus growth within the bag.
Protects the goods from adverse climatic conditions during transit.
Lower investment costs and lower total annual costs.

Silo Bag Mounting Instructions
step 1
Take out the SILO bag from the box.
step 2
Cut the blue cords taking care NOT TO CUT the white cords.
step 3
Open, unfold and lay it out flat as shown below
step 4
Place the bag right between the backstop and the tunnel, with the black folded edges facing the tunnel and the white edges facing the backstop.
step 5
Now mount the bag onto the machine pushing it far forward.
step 6
ORotate the bag, so the plastic is levelled on the holding pan under the tunnel with the logo facing the side of the tunnel.
step 7
Now remove all the remaining white cords.
step 8
Grab the plastic at the lower inside edge and pull out almost 8-10 feet of the bag. In the case of grains, the bag has to be pulled from the outside edge.
step 9
Now attach the stretch rope and seal the free end.
step 10
Ensure that the bag is not binding on the machine, the rope and pan are well fastened.
step 11
Also ensure the ‘stretch bars’ with the filled bag DO NOT exceed 11” in height.
step 12
Extra room will be needed for expansion.
step 13
The RED rape you see near the logo indicates that 5 folds remain until the end of the bag.
step 14
On completion of filling seal, the open end immediately.
step 15
Now vent the bag quickly with a 3” to 4” strip of repair tape on the finished end.
step 16
Make a 1-inch ‘X’ through the tape and bag and let it vent for 2 to 3 days till it stops releasing the gas built up within and reseal. Please note that inhaling silage gases is hazardous.
