Bags on a roll: when the right bag comes 500 at a time

The newest line in the plant is also the simplest: a clear layflat bag, open mouth, perforated on a roll so the line tears one bag at a time. Simple is the point.

The newest line in the plant is also the least complicated thing we make: a clear layflat bag, open mouth, no lip, no adhesive strip. What makes it a product is how it's packed — bags perforated end to end on a roll, so a packing station tears one off the way you tear a bag off the roll at a grocery produce aisle, scaled up and toughened for fulfillment.

Why a roll instead of a box

At a packing station, the container the bags arrive in is part of the workflow whether anyone designed it or not. A boxed stack means fishing for the next bag, static cling pulling up two at a time, and wicketed stacks mean wire, and wire means the last few bags on every wicket tearing at the holes.

A roll is a dispenser that ships as itself. It sits on a spindle or in a simple cradle, the perforation gives a clean one-hand tear, and the next bag is always in the same place. For stations bagging hundreds of items a shift, seconds per bag are real money, and so is never bending into a carton for the next handful.

What's set per job

The roll format has more freedom than the finished bag suggests. Each of these is a decision, not a constraint:

  • Size — our first stock item runs 18 × 24, and any width and length cuts to order.
  • Gauge — 1.25 mil is the stock roll-bag weight; lighter protection than a mailer because the bag usually rides inside something else.
  • Core and roll count — wound on a 3-inch core; bags per roll set to what a station can lift and load. The stock item runs 500 per roll.
  • Perforation pitch — matched to the bag length so every tear lands between bags, not through one.
  • Film options — the same extrusion line that makes everything else: clear, tinted, or an embossed non-slip finish where the filled bags ride inclined conveyors.

Where a roll is the wrong answer

An open-mouth bag has no closure — that's the format. Contents get taped, heat-sealed, folded, or the bag rides inside a mailer or carton that does the closing. If the bag itself needs to seal at the station, a self-seal bag or a mailer with an adhesive strip is the right product, and we'll say so rather than sell you a roll.

Amazon prep is the other boundary: bags over the size thresholds need suffocation warnings, and a warning-printed bag is its own product with its own compliance rules. The roll line is for the plain workhorse bag — the one you use ten thousand of and think about never.
