Backing Stock 

What is backing stock?

A backing stock is a second layer of material that goes behind the stock that is printed on. For corrugated boxes, this backing stock will always be E-Flute corrugated cardboard. Because we can’t print directly onto corrugated cardboard, E-Flute corrugated cardboard will always serve as the backing stock.

For paperboard boxes, backing stock is optional. A less refined material than the stock that we print on, this material can be used on the inside of your boxes for structural purposes when your package’s contents exceed 2 lbs. For paperboard boxes, we offer backing stock as either a coated white paperboard liner or an uncoated kraft paperboard liner. This option is available for our value coated white paperboard and our standard uncoated kraft paperboard options.
