When it comes to shipping in the e-commerce world, efficiency, affordability, and protection are key. Poly mailers are a popular choice for businesses of all sizes, offering a lightweight and durable solution that helps cut costs without compromising product safety. In this guide, we’ll explore what poly mailers are, why they’re used, and how to select the right type for your business needs.
What are poly mailers?
Poly mailers are lightweight, moisture-resistant envelopes made from polyethylene. Unlike traditional boxes, they offer a slimmer, more flexible packaging solution ideal for non-fragile products. These mailers are available in various types, some with added features like padding for extra protection or eco-friendly materials that help reduce environmental impact. Thanks to their durability, poly mailers are a go-to option for e-commerce businesses aiming to cut down on shipping expenses while ensuring safe delivery.
Poly mailers vs. boxes: why should I use poly mailers?
Poly mailers offer several advantages over traditional boxes:
- Cost Savings: Poly mailers are compact and reduce dimensional weight, which is often a factor in shipping fees. Because they weigh less than boxes, they generally result in lower postage costs.
- Space Efficiency: Poly mailers take up less space in storage and during transit, helping businesses streamline packing and delivery.
- Custom Branding: Poly mailers can be easily customized with logos, colors, and designs with lower MOQ, making them an effective tool for brand visibility. A branded package can enhance customer experience and strengthen brand loyalty.
- Eco-Friendly Options: Many suppliers now offer recyclable or compostable poly mailers, allowing businesses to support sustainable practices.
- Additional Padding: For products needing extra protection, bubble-lined poly mailers provide a convenient, protective layer, reducing the need for added packaging materials.
Ideal ecommerce products for poly mailers?
Poly mailers are ideal for non-fragile items, soft goods, or products that come with sturdy packaging. Because they are lightweight and flexible, poly mailers are a great choice for items that don’t need rigid protection and can handle the usual handling during shipping. If a product can withstand being in a soft-sided mailer without damage, it’s likely a good candidate for a poly mailer.
However, it’s best to avoid using poly mailers for fragile or crushable items—like glassware, foods that can easily crumble (e.g., chips), or delicate electronics—unless these items are already in robust, protective packaging. In those cases, boxes are often a better option.
Here’s a list of common e-commerce products that work well with poly mailers:
- Apparel: Clothing items such as T-shirts, jeans, socks, and other soft garments fit well in poly mailers since they’re naturally resistant to damage during shipping. Footwear with sturdy boxes can also be shipped in poly mailers if extra protection isn’t necessary. However, for items with intricate details (like beading on dresses), a box might provide better security.
- Fabric-Based Products: Poly mailers work well for textiles such as bedding, sheets, and small blankets. Fabrics like yarns or loose materials can also be shipped in poly mailers if wrapped securely.
- Phone Accessories: Small, lightweight items like phone cases can be safely shipped in poly mailers as long as they don’t need extensive protection from impact.
- Art Prints and Posters: Flat prints and posters that aren’t easily bent or damaged can be shipped in poly mailers, though using a protective sleeve inside the mailer is often recommended to prevent any surface wear.
- Books and Printed Media: Books, magazines, and other print materials that are naturally durable and don’t require rigid protection can be shipped in poly mailers.
- Health, Beauty, and Wellness Products: Many non-fragile beauty products, like packaged skincare items or cosmetics in durable tubes, can ship safely in poly mailers. However, fragile items like glass perfume bottles are better suited to a box.
- Sturdy Packaged Items: Products that come pre-packaged in protective containers, such as boxed shoes, packaged toys, or well-protected electronics, can be placed inside a poly mailer for additional protection without the bulk of a shipping box.
By selecting the right products for poly mailers, you can reduce shipping costs and streamline fulfillment without compromising on the safety of your items.
4 types of poly mailers
There are several types of poly mailers available, each with unique features to meet different shipping needs:
- Standard Layflat Poly Mailers: These basic poly mailers have no internal padding, making them the most cost-effective option. They’re best for items that don’t need extra cushioning, such as soft goods or items that aren’t easily damaged. While they cover the product, they offer minimal protection beyond a simple enclosure.
- Bubble Mailers: Equipped with a bubble lining, these mailers provide extra cushioning for more delicate products.
- Expansion Poly Mailers: With expandable sides, these mailers are perfect for bulkier items or multiple products.
- Compostable Poly Mailers: Made from biodegradable materials, these eco-friendly mailers help reduce plastic waste and support sustainable business practices.
Does USPS accept poly mailers?
Poly mailers are widely accepted by the United States Postal Service (USPS) for various shipping services. However, it’s essential to ensure that the mailer is properly sealed, labeled, and meets USPS size and weight requirements. While poly mailers are typically best for First-Class and Priority Mail, always check the latest USPS guidelines to ensure compliance and avoid additional charges.
How do you measure a poly mailer for shipping?
Choosing the right-sized poly mailer is essential to ensure a snug fit, reduce wasted space, and minimize shipping costs. Here’s a quick guide to common sizes based on popular items often shipped in poly mailers:
