Custom size pre-opened bags on a roll are built to a width and length outside our standard size range — made for products or packaging equipment that a stock bag size doesn’t fit. This is common for OEM packing lines, unusual product geometries (long, narrow, oversized, or irregular shapes), or machines built around a non-standard bag envelope. We manufacture custom width, length, thickness, perforation, and roll configuration to match your product and equipment. MOQ starts at 30,000 pieces.
When You Need a Custom Size (Instead of a Standard One)
Most pre-opened bag needs are covered by standard stock sizes. A custom size is worth specifying when:
- Your product’s dimensions fall between standard sizes, or outside them entirely
- Your bagging equipment has a fixed feed path or index length that only fits a specific bag length
- The product shape is long and narrow, unusually deep, or otherwise doesn’t fit a standard rectangular bag well
- You’re replacing an existing OEM bag spec and need to match it exactly (roll core, winding direction, perforation pitch included)
Size Range
Custom widths from 2″ to 36″ and lengths from 2″ to 72″ can be manufactured. Below are a few examples of custom sizes we’ve produced outside our standard range:
| Width × Length | Approximate metric size | Typical use case |
|---|---|---|
| 3″ × 4″ | 76 × 102 mm | Compact, non-standard component packs |
| 4″ × 8″ | 102 × 203 mm | Long, narrow parts |
| 6″ × 10″ | 152 × 254 mm | Extended-length assemblies |
| 8″ × 12″ | 203 × 305 mm | Larger irregular-shaped products |
| 10″ × 15″ | 254 × 381 mm | Maximum standard-adjacent example |
Sizes outside this table — including widths up to 36″ and lengths up to 72″ — can be produced. Tell us your product’s width, length, and depth (plus loading clearance) and we’ll confirm the right custom dimensions.

Why OEM and Nonstandard-Dimension Buyers Choose Custom Sizing
A standard-size bag either wastes material (too large for the product) or doesn’t fit the product or equipment at all (too small or the wrong proportions). Custom sizing solves both problems by building the bag around your actual product dimensions and your machine’s feed requirements — rather than making your product or process fit a stock bag.
Automation and Packaging Equipment
We fit custom-size rolls to the feed, perforation, and pitch requirements of Autobag®, APS (Automated Packaging Systems), PDC International, Sharp Packaging (MAX), and FAS equipment — as well as OEM or proprietary bagging lines. Send us your machine’s make and model, feed path, index length, and maximum roll diameter, or your current bag drawing/sample, and we’ll match the new roll to it.

How Custom Size Pre-Opened Bags on a Roll Work
The bags come pre-opened and perforated on a continuous roll, built to your specified width, length, and roll configuration. During packing, product loads through the open end, the bag separates at the perforation, and the bag is sealed — the same sequence as a standard pre-opened bag, but sized and configured to your exact product and equipment rather than a stock dimension.
Applications
Common for OEM packing lines replacing an existing bag spec, unusually shaped or oversized components, long/narrow parts (cables, rods, extended assemblies), and equipment with a fixed feed path that only accepts a specific bag length. If you’re matching an existing spec, send us your current bag or its drawing and we’ll replicate the dimensions and roll configuration.
Automation and Packaging Equipment
Equipment fit is not assumed. Review machine envelope, feed path, index length, sealing jaws, core support and maximum roll diameter. Provide equipment drawings or specifications, the current package where available, filling and sealing details, and operating constraints before the final format is approved.
FAQ
What’s the size range for custom pre-opened bags on a roll?
Width from 2″ to 36″ and length from 2″ to 72″. Dimensions outside this range can be discussed case by case.
Do I need a custom size, or will a standard size work?
If your product fits within our standard size table (see the standard sizes) and your equipment has no fixed constraints, a standard size is usually more cost-effective. Custom sizing makes sense when your product or equipment doesn’t fit a standard dimension.
Can custom size bags be made in different thicknesses?
Yes — thickness runs 1–5 mil, and can be matched independently of the custom width and length.
Can custom size bags be configured for automated packing equipment?
Yes — we fit rolls for Autobag®, APS, PDC International, Sharp Packaging (MAX), FAS, and OEM/proprietary bagging lines. Send your machine’s make/model, feed path, and roll constraints and we’ll match perforation, pitch, roll core, and feed direction to it.
What’s the minimum order for a custom size?
MOQ is 30,000 pieces per size/spec combination.
How do I match an existing OEM bag spec exactly?
Send us your current bag sample or a controlled drawing (dimensions, perforation pitch, roll core, winding direction). We’ll replicate the specification and confirm before production.
