Having problems figuring out which size you will need for your product?

Please reference the chart below to help you with your sizing needs. If you are unsure of your products bulk density you can fill a 1 cubic foot box with your product and weigh it.

To figure the correct bag size, you will need the bulk density of your product as well as how many lbs you will need in your bags. Please use this example below:

• Customer wants to put 50 lbs into a bag
• Product’s bulk density is 23
• Take lbs (50) –divided by - bulk density (23) = bag volume (2.17)
• Then based on the style of bag that you need – reference chart.

For this example if you needed an SOM, the closest size on the chart is 2.18 so you would need an SOM bag of size 17x5x41.
