Paper-Poly Bags FAQ
What is a paper-poly bag?
It is a composite sack made by laminating kraft paper to woven polypropylene fabric. The paper provides a printable, natural-looking face; the woven PP provides tear and drop strength far above multiwall paper sacks of the same weight.
Are paper-poly bags good for seed and alfalfa?
Yes. They are widely used for alfalfa, grass and forage seed in 50 lb (22.7 kg) formats because they stack well, print well and can be micro-perforated to let seed breathe.
Do you offer a moisture barrier?
A PE inner liner or a PE extrusion layer between paper and fabric gives a strong moisture barrier for hygroscopic products.
