What are poly mailers?

Poly mailers (or postage bags, mailing bags) are the cheapest shipping packaging solution available to merchants. Mailer bags are lightweight and can be easily stored in warehouses due to their reduced size. Transportation is also more affordable since postage bags take up much less space than corrugated boxes. Packhelp offers a range of custom mailing bags in various sizes and materials to help your business take branding to the next level.

Can I ship anything in poly mailers?

Poly mailers are a top-rated shipping packaging solution for posting and ecommerce brands; they are used as primary packaging in various industries. Postage bags are sturdy, waterproof and difficult to pierce, making them perfectly safe for delivering and returning goods. Mailing bags are the most reliable and cost-effective shipping packaging available on the market and are suitable for a wide range of products. They weigh next to nothing, are easy to store, and are engineered to protect the products inside during transit. Our mailing bags come with safe sealing strips for sending/returning, making them ideal for apparel brands; you can pack anything using postage bags within reason. For example, delicate items are not recommended to transport using poly mailers as primary shipping packaging unless used as an extra protective layer for an existing box.

Can I buy sustainable postage bags??

Packhelp's poly mailer collection is exclusively dedicated to eco-friendly options. Our lineup prominently features Bio Poly Mailers made entirely from starch. This assortment of custom mailing bags provides an environmentally responsible choice for businesses, offices, and warehouses, ensuring you can ship guilt-free with sustainable packaging solutions.

FAQ

Are these mailing bags waterproof?

It depends. Our classic poly mailer bags are made from highly durable LDPE foil, while our more eco-friendly alternatives are made from waterproof bioplastic. This material is great to serve as an additional layer of protection to prevent your box from rain, water and snow. Our paper-based postage bags are water-resistant. They can take a bit of rain in transit.

Can I design my own poly mailers?

Yes, we provide customisable options along with pre-printed and plain postal bags. Design your poly mailers in our online editor or on your chosen software - we offer multiple personalisation options, from size and print area to custom colours, style & more.

What are some common uses for poly mailers?

Mailing bags can be used as protective packaging and a shipping solution on their own. Soft goods (e.g., clothing & accessories) and printed material (e.g., magazines) can be shipped using just postal bags. They are a favourite among fashion brands. They are also great for protecting mailer boxes from damage, rain and other elements.
