Custom Poly Bags / Parts Bags
Select parts bags by what protects the part, not by bag size alone.
A custom parts bag keeps components clean, contained and identifiable between production, storage, shipping and assembly. First, define the part shape, weight, surface finish and the handling steps it must survive.
Direct Answer
Start with the part, then specify the bag.
A parts bag is not just an open poly bag. It may need thicker film for sharp edges, a gusset for bulky assemblies, an anti-static additive for electronics, a zip closure for repeated opening or printed fields for traceability. Defining those conditions first prevents a bag that fits the part but fails in storage or transit.
Then, send part dimensions, weight, edge condition, quantity per bag, shipping method and any cleanliness, moisture or static-control requirement.
Selection Matrix
Match the bag feature to the risk it controls.
| Part condition | Bag feature to discuss | Why it matters |
|---|---|---|
| Sharp edges or heavy metal parts | Thicker film, reinforced seal or gusseted bag | Reduces puncture and seal failure during packing and transport. |
| Static-sensitive electronics | Anti-static or ESD-reviewed film | Protects sensitive components from electrostatic discharge during handling. |
| Multiple pieces or mixed hardware | Gusset, zip closure or printed identification field | Keeps the kit together and makes sorting or counting faster. |
| Retail or pegboard display | Header bag with euro slot or reinforced header | Provides a stable hanging point and clear product visibility. |
| Automatic bagging equipment | Roll-fed film or consistent bag dimensions | Improves line speed and reduces jams caused by dimension variation. |
Choose the bag style from the handling route.
- Flat poly bag: lowest material use for single flat or small components that do not need expansion.
- Gusseted bag: adds depth for bulky assemblies, bundled parts or packing several items together.
- Zipper bag: supports repeated opening, inspection and controlled reclosure on the production floor.
- Header bag: adds a reinforced top section for hanging retail parts or service kits.
- Die cut handle bag: provides an integrated carry handle for heavier parts or field-service kits.
If the final handling route is unclear, send the part details first. Then, we can compare these routes.
Parts Bag Questions
What buyers ask before ordering custom parts bags
What film thickness should a parts bag use?
First, consider part weight, edge sharpness and handling. Thin film can suit clean, lightweight components, while heavier or abrasive parts usually need a thicker gauge and stronger seals. Then, we confirm the minimum suitable gauge after reviewing the part.
Are anti-static or ESD parts bags available?
We can discuss anti-static and ESD-reviewed film options for electronic and static-sensitive components. Our team will then confirm the required surface resistance and documentation against the part and handling environment.
Can parts bags be printed with barcodes or traceability fields?
Yes. We can place barcodes, part numbers, storage fields and inspection dates on the bag where artwork and print contrast support reliable scanning.
Can the bag be used on an automatic packing machine?
We can produce bags and roll-fed film for automated lines. Provide the machine model, opening method and dimension tolerance so we can review the format correctly.
Are parts bags food-safe?
We normally specify parts bags for industrial protection. If a bag will contact food, state that clearly so we can select food-contact materials and the correct compliance documentation.
What is the minimum order for custom parts bags?
Minimums depend on bag size, film gauge, printing and whether custom tooling is required. We can review a trial quantity before a larger production order.
Are custom parts bags recyclable?
However, single-material polyethylene bags work better with film recycling streams than mixed-material laminates. Check local collection requirements and any anti-static or additive content before making a recycling claim.

Heavier kits often need Die Cut Handle Bags. Hanging retail parts may suit Header Bags. Bulkier components usually call for Gusseted Poly Bags.
Parts Bag Requirement
Send the part dimensions, weight, quantity per bag and the handling method.
Include any static, moisture, puncture or traceability requirement so the film and closure can be matched correctly.
