Frequently Asked Questions
What types of automated baggers are these compatible with?
These pre-opened bags on roll are designed for Autobag®-style and similar automatic bagging machines that use core-mounted rolls. Verify your equipment’s core diameter, bag width, and pitch specifications before ordering to confirm compatibility.
How does the 4 x 4 compare to the 6 x 6 autobag format?
The 4 x 4 bag is suited for smaller items — individual fasteners, jewelry components, beads, small capsules, or single-serve sample sachets. The 6 x 6 bag handles slightly larger items like multi-piece hardware sets, medium electronics, or small retail kits.
Can these bags be used for food or pharmaceutical products?
Yes — made from FDA/USDA-compliant virgin LDPE, these bags are suitable for food-contact applications including confections, snack samples, and small produce items, as well as pharmaceutical sample packaging.
