Description
Overview

Poly Mailers

Ounces instead of a pound, the lightest way to ship anything that cannot be crushed.

A printed polyethylene bag with a self-adhesive closure. For apparel and soft goods the weight saving is paid back on every single parcel, which is why fashion e-commerce runs on it.

Crafted to specification

Every detail. Intentional.

Weight is the whole case

A fraction of a box's mass on every shipment.

Best for soft goods

Apparel and textiles that cannot be crushed.

Recycled content available

High post-consumer polyethylene at near-identical performance.

Not kerbside recyclable

Store drop-off or compostable grades are the honest routes.

Gauge against the contents

2.5 mil standard, heavier for sharp or dense goods.

A second adhesive for returns

Apparel almost always needs the second seal.

Measure Twice

Sizing & dieline.

We cut Custom Poly Mailers to a dieline built around your product instead of pulling a stock size off the shelf. Send us the length, width and height of the item (or the item itself) and we return a measured dieline, free, before you commit to anything.

How to measure
01
Measure the product

Length, width and height of the item itself, at its widest points. Measure the product, not the box you happen to use today.

02
Add clearance

Allow 2–4 mm on each axis for a snug fit, and more if you are adding foam, a pillow insert or tissue.

03
Give us the order

We quote as Length × Width × Height. Tell us whether you are working in millimetres or inches and we match it.

✦ Not sure of your size? Send us the product and we measure it and build the dieline.

What It Costs

Pricing & minimums.

We price Custom Poly Mailers per specification rather than from a fixed list, because the same build in two different finishes can land at very different numbers. Below is what actually moves the price, so you can shape the spec before you request a quote.

What moves the price
Quantity

The single biggest lever. Unit cost falls sharply as volume rises, because setup and tooling spread across more pieces.

Material and thickness

Board weight and stock choice change both the raw material cost and the shipping weight of the finished run.

Finishing

Foil, spot UV, embossing and soft-touch each add a pass on press. One or two lift the box; five compound the cost.

Print coverage

Full-bleed print inside and out costs more than a one-sided design on natural stock.

Inserts and hardware

Foam, moulded pulp, velvet pillows, magnets and ribbon are priced per piece on top of the box itself.

Timeline

Standard production is the base rate. Rush moves you up the production queue and carries a surcharge.

Frequently Asked Questions

Questions, answered.

Everything you need to know about Custom Poly Mailers.

2.5 mil is our standard gauge, and we go heavier for sharp-edged or dense contents that could puncture the film. The film is co-extruded, which gives it better tear resistance than a single-layer bag of similar weight.

Folded apparel ships fine in the standard gauge. Boxed shoes, hardware or anything with hard corners should go up a gauge.

Yes, we add a second adhesive strip below the first so the customer can use the same bag to send an item back. They open the mailer along the tear notch, then peel the second liner when a return is needed.

For apparel, where returns are common, we would include the second strip by default. It adds very little to the bag and saves the customer hunting for packaging.

The peel-and-seal adhesive bonds to the film so firmly that the bag can't be opened and closed again without visible damage. That makes interference in transit easy to spot.

Opaque film grades keep the contents out of view, which helps with higher-value items. The film is water-resistant as well, so the contents stay dry when a parcel is left out in the rain.
