# Paper-poly bags

> Paper-poly composite bags: kraft paper laminated to PP woven fabric for seed, alfalfa, feed, chemicals and building materials. Side gussets, liners, windows, sewn or pinch bottoms.

A paper-poly bag puts a natural kraft paper face on a woven polypropylene body. You get the premium look and print surface of paper with the strength and moisture resistance of plastic, which is why seed, forage and specialty-feed brands use them.

## 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.
