Blue Printed Mailers
Blue print leaves room around the sealing flap.
PARCEL PACKAGING
Custom Biodegradable Mailers
Size the mailer around the whole order, including its inner bag and inserts. We make self-seal outer bags with your print and an optional tear strip.
Self-seal flapsFrom 1,000 pcsExisting samples free
The white mailers show two layouts for black print. On your artwork, reserve a clear area for the shipping label.
What Goes on the Mailer Quote
- Custom mailer orders start at 1,000 pcs.
- Specify the usable bag size, the flap length and how the customer will open the parcel.
- Choose the film color and send artwork showing where the shipping label will sit.
- We review film thickness and an optional second layer against the parcel you plan to ship.
- We do not currently have finished-mailer compostability certificates or test reports.
How We Build a Self-Seal Mailer
A packed parcel and the label you use at dispatch let us check two things on a sample. The flap needs to close, and the label needs a clear, flat surface.
Measure the Complete Parcel
Include tissue, inserts and the inner bag in the measurement. A thick parcel takes up some of the length you need to reach the sealing flap.
Film Production and Conversion
We blow, print and convert the film in our factory. We check the usable body and flap separately when we cut the mailer.
Closing and Reopening
An adhesive strip closes the parcel. A tear strip can help the customer open it. Tell us separately if the bag also needs a return closure.
Print around the Shipping Label
Show us your actual label size. We can move the logo clear of both the label area and the part that folds over at the seal.
Run the Sample through Dispatch
Pack an order, apply your label and seal it the way your team normally does. Then open it from the customer’s side.
Check the Finished Mailers
Before packing, we check dimensions, print, seams and the closure you ordered. Cartons carry the agreed counts and size references.
Printed Mailer Samples
These samples show lettering on white film, repeat patterns and smaller logos. Your parcel determines the size and flap.
Pink Patterned Mailers
A small repeating pattern covers the pink front.
Cream Logo Mailers
A compact black logo sits near the lower edge.
White Printed Mailers
A small top logo leaves space for an information panel below.
Measure the Parcel, Not the Unpacked Product
Measure the product with its tissue, inner bag and any inserts. Use the mailer size guide to distinguish usable bag dimensions from the sealing flap.
- Parcel width
Measure across the widest part of the fully packed order. - Usable Bag Length
Keep the usable length separate from the sealing flap in your specification. - Allowance for Depth
Account for the parcel’s thickness so the opening and flap can be used as intended. - Packed Sample Check
Insert the actual parcel, close the sample and check the fit before approving its dimensions.
Sealing at Dispatch, Opening on Arrival
Decide where the team will seal the parcel and where the customer should tear it open. A second adhesive strip for returns is a separate request.
- Adhesive strip
Choose where the strip lands when the packer folds the flap over the parcel. - Flap Length
Confirm enough flap space for the packed item and the intended closing position. - Tear-Open Detail
A tear strip can be included where required; review the opening on the finished sample. - Seal on the parcel
Close the sample with the parcel inside. Check that the flap lies flat from one end of the strip to the other.
Film Thickness and Layers Are Separate Choices
Quote the material, thickness and layer construction together so two offers can be compared on the same basis.
- Film Formulation
Record the proposed material blend. The cornstarch range explains the starch-based options. - Thickness in Microns
Provide a target thickness or describe the parcel weight and handling needs for review. - Optional second layer
If your order calls for two layers, ask which films will make up the outer and inner faces. - Tear and Load Requirements
State the performance your parcel needs and check it on the sample before bulk approval.
Leave a Usable Space for the Shipping Label
Place your actual shipping label on the artwork at full size. Check that it leaves the logo and the customer’s opening instructions visible.
- Film color
Compare the ink on the film color you’ll actually order. - Logo Position
Place the brand mark where seams, folding and labels will not obscure it. - Label area
Place the full label on a packed mailer to check that the barcode sits clear of seams and folds. - Print Approval
Confirm the artwork, colors and required wording on the chosen film before production.
Separate Mailer Sizes at the Packing Station
Use distinct size references and agreed pack counts so a replenishment carton can be identified without opening every pack.
- Packs at dispatch
Tell us how many mailers your team wants to take to one packing station at a time. - Size codes
Use a different reference for each size so staff can pick the right mailer without opening a pack. - Carton Counts
Confirm how many mailers go in each carton as part of the order specification. - Shipment Marks
Set the carton marks your warehouse needs alongside the destination and shipment details.
Trying a New Mailer Film
Seal a fully packed sample and apply the label before comparing films. The adhesive, print and seams are part of the finished parcel.
The Proposed Film and Layers
We can review PBAT/starch compounds and suitable PLA/PBAT/starch blends for your parcel. Ask for the film thickness and the layer construction on the same quote.
Discuss Mailer Materials
Replacing a Conventional PE Mailer
Pack the same order in the PE mailer and in the proposed sample. Apply your usual shipping label, seal each flap and compare how the bags handle and open.

Evidence for a Printed Mailer
We currently have no compostability certificate or test report for the finished mailer. If your artwork will carry a claim, check whether the evidence covers the printing and adhesive as well as the film.

How the Flap Is Made
We print the film, cut and seal the body, then add the adhesive and any tear-opening feature specified for the order. We check the closure before packing.
Mailer Size & Thickness Guide
Compare smaller dispatch bags and larger mailers using the packed order as your starting point. The sealing flap is listed separately so it is not counted as extra packing space.
We quote film thickness as the total of both bag walls in microns (µm). The table gives reference figures. Confirm how each was measured before using it for an order.
Swipe the table sideways to view every column.
| Closure style | Width × body length (cm) | Flap (cm) | Reference thickness (µm) |
|---|---|---|---|
| Self-adhesive mailer | 16.5 × 23.5 | 4 | 60 |
| Single adhesive strip | 25.5 × 32.5 | 4 | 63 |
| Single adhesive strip | 26 × 38.5 | 4 | 63 |
| Two adhesive strips | 33 × 42 | 8 | 63 |
| Two adhesive strips | 39.5 × 45.5 | 8 | 81 |
| Two adhesive strips | 42 × 59.4 | 8 | 81 |
| Two adhesive strips | 60 × 65 | 8 | 81 |

Mailer Purchasing Questions
Apply your normal label to a packed sample, right where it will sit at dispatch. A label that sticks to one film may lift from another, especially where the bag folds.
A tear strip opens the parcel once. If customers need to send items back in the same bag, ask about the remaining bag length and a second closure.
Tell us what exposure the parcel will face. The film, seams and adhesive flap all affect protection, and we make no blanket waterproof claim for the mailer.
We can print your logo. We currently have no compostability certificate or test report for the finished mailer. If you need certified packaging, check the required evidence before paying for a sample or approving a claim.
Our minimum is 1,000 mailers. Send the quantity for each size and design so we can tell you which runs can be combined and at what price.
Existing samples are free. A custom mailer sample costs US$30–50 and takes 3–5 days after payment. We refund the full sample fee with a bulk order. Shipping is separate. See how to arrange a custom sample.
Bulk production takes 7–9 days after payment. Add transit time to your destination. If the order must reach a warehouse by a particular date, put that date on your inquiry. See the production and delivery stages.
