Poly Mailers
Poly mailers for clothing, soft goods and everyday shipping
Shop poly mailers by listed size, material thickness, closure and case count. For folded clothing and other non-fragile items, a mailer can be a practical alternative to a carton. Start with the packed item: its width, length and thickness determine the size you need. Then compare white, clear-view or black poly mailers and select a case quantity that fits your order volume.
The 10x13 poly mailers below are three specific starting points. Their listed dimensions are not a guarantee of usable interior space: allow room for the item's thickness and the adhesive closure, and test the fit before committing to a larger order.
Compare 10x13 poly mailers
| Product and SKU | Listed size | Thickness and closure | Case count |
|---|---|---|---|
| Black poly mailers — CPM1013BK | 10 x 13 in | 2.5 mil, self-seal | 100 mailers |
| Clear-view poly mailers — CV1013100PK | 10 x 13 in | 2.5 mil, self-seal | 100 mailers |
| Clear-view poly mailers — CV1013 | 10 x 13 in | 2.5 mil, self-seal | 500 mailers |
The two clear-view examples have the same listed size and thickness but different case quantities. Compare the exact SKU and case count when reordering; a similar product name does not establish the same pack quantity.

Divide the displayed case price by its mailer count to calculate the product price per mailer. For an order-level comparison, add quoted shipping and divide by the total number of mailers. Compare equivalent sizes and thicknesses before choosing the lowest unit price.

Use each row's dimensions, format and count to compare these options. An expansion mailer adds depth to its listed format; check its specific dimensions instead of treating it as interchangeable with a flat mailer. Black and clear-view options also serve different presentation needs.
Choose a mailer for the contents
| What you are packing | Start with | Check before buying |
|---|---|---|
| Folded clothing or soft accessories | A flat self-seal poly mailer | Packed thickness, fit and room to close the seal without forcing it |
| A bulkier soft item | An expansion mailer | The listed depth as well as width and length |
| An item whose appearance matters through the package | A clear-view mailer | The viewing area and a suitable label position |
| An item needing cushioning or crush protection | A padded format or properly sized carton | The complete protective packing method; plain poly film supplies no cushioning |
Buying poly mailers in bulk
Build your order around the sizes you actually use. Keep separate counts for each SKU, and compare smaller and larger case packs using the same unit calculation. A larger case only helps if its contents fit your orders and you have room to store it.
For a multi-case order or recurring requirement, request a bulk quote with the SKUs, case quantities and delivery ZIP. Include your expected reorder frequency if known. If you are matching another supplier's packaging, the Uline poly mailer alternatives guide explains which specifications to compare.
Poly mailer questions
Will a 10x13 poly mailer fit my product?
Measure the item as it will ship, including folds and any inner packaging. Compare all dimensions and leave room for closure. A flat item's width and length alone cannot confirm the fit of a thicker item.
Are these examples self-seal?
Yes. All three linked 10x13 examples are listed as self-seal. Check the individual listing for closure details on other products, particularly when a return mailing is part of your process.
Should I choose a poly mailer or a padded mailer?
Plain poly mailers suit contents that do not need cushioning. Browse bubble mailers or padded mailers when padding is needed, and use a carton and appropriate protection when the contents need a rigid package.
Complete your packing setup with shipping labels and packing list envelopes, or browse the broader mailers and envelopes collection.
For larger white poly mailers, compare these exact listed dimensions and case counts with the 10x13 options above. A nominal 14.5x19 or expansion dimension is not a promise of usable space after the closure and packed-item thickness.
| SKU | Listed dimensions | Listed film | Mailers per case |
|---|---|---|---|
| B876100PK | 14.5 × 19 in | 2.5 mil; white | 100 |
| EPM20244 | 20 × 24 × 4 in; expansion format | 2.5 mil; white | 100 |
For 350 mailers of one selected 100-count format, four cases supply 400. Fit the actual contents with their packing, leave space for the closing flap and check a sample before replacing a current size. These unpadded poly mailers do not provide the cushioning of a bubble mailer or the rigidity of a corrugated carton.
