Choose From Multiple Substrate Options
-
Tyvek
SUPERIOR DURABILITY
Tyvek is extremely strong and hard to tear, and is FDA-approved for direct food contact. If you need a more affordable option for non-food applications, choose our kraft option. For large scale non-food applications choose our Sewn Bag option that comes with hanging strings.
-
Kraft
AFFORDABLE
Kraft is our most budget-conscious substrate, delivering effective protection at a great price. For food applications, use our Tyvek option which is FDA-approved for direct food contact. For large scale non-food applications choose our Sewn Bag option that comes with hanging strings.
-
Sewn Cloth Bag
HEAVY DUTY
Our sewn bag substrate is the ideal solution for large scale non-food applications, with sizes up to 80 units. The sewn bag offers even more durability than our heat-sealed tyvek and kraft substrates and the open weave allows air to penetrate at a faster rate. If you need a more affordable option for non-food applications, choose our kraft option. For food applications, use our Tyvek option which is FDA-approved for direct food contact.
