Light Duty Packaging Poly Bags are supplied pre-opened on a continuous roll in 2 Mil, 4 Mil, and 6 Mil thickness options. They provide a practical format for packing nuts, bolts, fittings, fasteners, assembly hardware, and other small industrial parts by hand or with compatible semi-automated and automated equipment.
2 Mil, 4 Mil and 6 Mil Options for Light Duty Packaging
2 Mil
A practical starting point for lighter products with smooth edges and lower handling stress, including light fasteners, small fittings, lightweight components, and general parts organization.
4 Mil
Provides more puncture and handling resistance than 2 Mil. Consider this gauge when parts are moderately heavier, edges are less smooth, or bags receive more handling during packing and shipping.
6 Mil
The heaviest option on this page. It provides greater film strength than 2 Mil or 4 Mil for heavier parts or more demanding handling conditions. Final suitability depends on the actual part and packing process.
Which Thickness Should You Choose?
| Thickness | Best starting point for |
|---|---|
| 2 Mil | Lighter parts, smooth edges, and basic handling |
| 4 Mil | Moderate weight, more handling, or added film strength |
| 6 Mil | Heavier parts or greater handling demand |
If you are unsure, send us the part weight, dimensions, edge condition, and packing method. We can help identify a suitable starting gauge for a sample or quotation.
Product Description
Each bag is open at one end and connected to the next bag on the roll by a perforation. The roll format keeps the next bag ready for loading and supports repeatable packing of small industrial parts.
Width, length, gauge, perforation, venting, print area, and roll setup can be matched to the part and packing method. Equipment use depends on the confirmed bag and roll configuration.
How It Works
The operator or bagging equipment presents the open bag, loads the parts, separates the filled bag at the perforation, and seals it according to the packing process. For hardware and small components, bag dimensions, film gauge, and perforation should match part size, weight, edge condition, and handling requirements. Venting or printing can be added where required.

Applications
- Nuts and bolts packed by count or kit
- Screws, fasteners, washers, and clips
- Small fittings and connectors
- Assembly and maintenance kits
- Small machined parts with an appropriate gauge and clearance
- General industrial components and spare parts
Why Use Pre-Opened Roll Bags for Light Duty Packaging?
Fast loading
The pre-opened presentation reduces the need to open individual loose bags before filling.
Simple parts organization
Clear bagging can help separate and identify fasteners, fittings, components, and kits.
Multiple film gauges
2 Mil, 4 Mil, and 6 Mil provide different starting points based on part weight, edges, and handling demands.
Manual or automated workflows
The roll format supports manual packing and can be configured for compatible semi-automated or automated bagging.
Custom configuration
Bag dimensions, perforation, venting, print area, and roll setup can be specified around the packed parts.
Customization Options
- Custom bag width and length
- 2 Mil, 4 Mil, or 6 Mil film
- Perforation suited to separation requirements
- Venting pattern where trapped air must escape
- Print zone and custom printing subject to artwork review
- Core, winding, roll diameter, and roll quantity
Automation and Packaging Equipment
For equipment-assisted loading, provide the machine model or controlled bag drawing, current sample where available, bag width and length, gauge, perforation pitch, core, roll diameter, winding direction, unwind direction, and sealing requirements. Compatibility is confirmed from the complete bag and equipment specification rather than the product name alone.
Why Choose RS Packing for Light Duty Packaging Poly Bags?
- Custom bag dimensions based on the packed part
- Confirmed 2 Mil, 4 Mil, and 6 Mil gauge options
- Custom perforation and roll configuration
- Venting and printing options developed from the project specification
- Samples and production details reviewed before order confirmation
How to Specify and Request a Quote
Send the part dimensions, weight, edge condition, pack count, required bag width and length, preferred 2 Mil, 4 Mil, or 6 Mil gauge, quantity, venting, printing, perforation, roll requirements, sealing method, and packaging-equipment details. Include a sample or controlled drawing when fit or process compatibility is critical.

Frequently Asked Questions
Should I choose 2 Mil, 4 Mil or 6 Mil?
2 Mil is a common starting point for lighter products and smooth-edged parts. 4 Mil adds more film strength for moderately heavier items or more handling, while 6 Mil is the strongest of the three options on this page. Send the part dimensions, weight, edge condition, and packing method if you need help choosing a starting gauge.
Can these bags be used for nuts and bolts?
Yes, when the bag size and gauge suit the part count, weight, and edge condition. A sample pack is useful when parts have concentrated loads or less-smooth edges.
Can the bags run on automated equipment?
The pre-opened roll format can support compatible equipment, but fit is not universal. Provide the machine and bag specifications so the core, roll, perforation, winding, and seal requirements can be checked.
Can vent holes or printing be added?
Venting and printing can be specified for the project. Provide the hole pattern or air-release need and the artwork, colors, coverage, repeat, and orientation for review.
What information is needed for a quotation?
Provide the part, dimensions, weight, edge condition, pack count, bag size, gauge, quantity, perforation, venting, printing, roll configuration, sealing method, and equipment information where applicable.
