Enhance Your Brand at a Fraction of the Cost of Branded Boxes

Enhance Your Brand at a Fraction of the Cost of Branded Boxes

Feb 17th 2023

Custom poly mailers deliver an exceptional customer experience at a much lower cost than branded shipping boxes - without sacrificing sustainability.

Apparel brands looking to customize their packaging will find branded plastic mailer bags significantly less expensive than custom paper mailers or boxes. They are also less expensive to ship and easier to store. As the world moves into a period of economic uncertainty, many brands seek to cut back on their expenses. A custom branded plastic mailer bag helps companies live up to their circularity and low carbon values while still keeping costs relatively low.

EcoEnclose is here to support all of your packaging needs with options to create customized designs. Read on to learn if customizing poly mailer bags is the right solution for your business.

Poly Mailers Defined

Also called plastic mailers or mailer bags, these are lightweight and durable plastic shipping bags for small products weighing less than 10 lbs. EcoEnclose's unique, 100% recycled poly mailers are available in 8  sizes, ranging from 6 x 9” to 24 x 24”, in ivory or grey, and can be customized with your brand’s logo and design colors.

Shipping your products in branded packaging creates a unique and personalized experience for your customers to help strengthen brand loyalty.

Customization Options

We print in one of two ways. Post-production printing is reserved for print orders ranging from 500 to 25,000 in quantity. Inline printing is for print orders at or above 25,000 units.

Post-Production Printing

In post-production printing, the printing occurs after the packaging has already been produced. Customize your mailers using packaging readily available on the EcoEnclose website. This option provides more limited design features such as single color prints and more constrained artwork boundaries. Still, it is a perfect solution for smaller businesses, with order minimums starting at 500 mailers.

We are also thrilled to print with black Algae Ink™. This printing capability is a huge win for sustainability, packaging, and the continued expansion of algae ink technology.

Inline Printing

For additional customization flexibility in artwork boundaries, colors, sizes, material thickness, and structural designs, use our high-capacity inline printing services.

Inline printing refers to packaging printed with customizations during the production process. This process is much more streamlined than the post-production route but can only be accomplished with relatively high volumes, starting at a minimum of 25,000 mailers.

Benefits of Custom Packaging

The shipped package is the first physical impression a customer has of an eCommerce business.

Brands, particularly those with deeply rooted values related to ethics and sustainability, miss out on a significant opportunity when they ship in plain packaging with no custom branding.

Gorgeous, well-designed packaging goes a long way in reinforcing to customers why they chose to order from your brand, a feeling that leads to increased loyalty and friend referrals. Because the time between purchase and product arrival builds consumers’ expectations, packaging that fails to meet the brand’s promise severely detracts from a customer’s impression of the brand.

custom recycled packaging

In addition, customized packaging inspires your customers to share and promote your brand on social media for free. The strange but unwavering unboxing trend is now ingrained in our culture for a reason.

Why is customization so effective? If your retail business is primarily online, your product shipment may be the only direct touchpoint with a customer. Use custom packaging to create a fun and unique experience for your customers while increasing brand recognition.


Many people think of shipping boxes or paper mailers when they think of "sustainable packaging." Curbside recyclable, paper-based solutions tend to align, in the public’s mind anyway, with environmentalism.

But, while we love our 100% recycled paper-based shipping solutions, recognizing that they are both recycled AND curbside recyclable, we also know that 100% recycled poly mailers have a leg up on our paper shippers on some sustainability factors.

Poly mailers are a much lower-cost option for shipping non-fragile items, such as clothing and other soft goods. The thin poly material weighs significantly less and takes up far less space than a box or paper mailer.

This thin material means that these mailers have a much lower carbon footprint than any equivalent paper mailer or shipping box. Learn how paper and plastic stack up from a sustainability perspective.

But, even though poly mailers are a cost-effective and carbon-efficient solution, we know many businesses hesitate to use plastic packaging.

At EcoEnclose, we want to equip brands with sustainable and eco-friendly packaging to meet all their shipping needs, regardless of the material type they decide to work with. Therefore, we have invested heavily in achieving 100% recycled poly mailers that contain 50% post-consumer recycled content. Post-consumer content refers to materials used and recycled by consumers, such as plastic bottles.

To further reduce waste and encourage circularity, our poly mailers are also equipped with an adhesive strip allowing your customers to send returns using the same mailer. Finally, end consumers can recycle these mailers with other thin plastic films at specified collection points.

To find a recycling location near you, use the directories on Earth911 or EcoEnclose also offers a Take Back Program for those who don’t have access to plastic film collection points. The poly mailers can be filled with #2 and #4 thin film and returned to our company for recycling. This plastic film is handled by EcoCycle, a local nonprofit recycler and zero-waste organization located in Boulder, Colorado.

Cost Analysis

Again, we stand behind all of our eco-friendly offerings. Within EcoEnclose, we often say, “If it’s on our site, feel good knowing the offering meets our strict sustainability framework. If it’s not, it is likely a packaging solution that does not align with our values.”

With that in mind, you have many different eco-friendly custom packaging options with EcoEnclose! If you want to ship in style, consider custom poly mailers, paper mailers, shipping boxes, and even custom tissue paper or stickers. But custom branding your 100% recycled poly mailers is likely the least expensive approach across all of these options. Here’s a quick comparison.
