The Product Boxes UK understands that when it comes to shipping and protecting your products, presentation and durability are key. That’s where our poly mailers come in a lightweight, durable, and cost-effective solution designed specifically for retailers, e-commerce brands, and businesses looking to make a lasting impression with every parcel they send out. Whether you’re posting clothing, documents, or delicate goods, our poly mailer are engineered to deliver protection, style, and brand visibility all in one compact solution.

Our Branded Poly Mailers Offer Versatile Protection for Every Shipment

Poly bags aren’t just for packaging, they’re an extension of your brand. These are designed to be tear-resistant, moisture-proof, and puncture-proof. For fashion retailers, they provide a sleek way to package apparel without the bulk of boxes. E-commerce businesses rely on them for their lightweight nature, which helps reduce postage costs without compromising product safety. From beauty items to tech accessories and apparel, these product shipping bags ensure every item arrives in pristine condition.

Their slim, secure design makes them ideal for postal delivery and courier services alike. They’re equally effective for storing items during transit, reducing the risk of scratches, dust accumulation, or external contamination. The opaque finish offers privacy, while optional interior bubble padding can provide added shock resistance for fragile items.

Our E-commerce Bags are Built to Last 

Our poly mailers are crafted using top-grade materials that guarantee strength, flexibility, and reliability. Our personalised ecommerce bags are precision-sealed and reinforced to protect your items in transit. From single-layer mailers for soft goods to multi-layer or bubble-lined versions for more delicate shipments, our materials are sourced for maximum effectiveness.

• LDPE: Flexible, strong, and ideal for regular shipments.
• HDPE: Tough, rigid, and great for heavier or sharp-edged items.
• Biodegradable options: For businesses committed to sustainability.

Each material is thoroughly tested for performance under various shipping conditions, ensuring that your items always reach your customers safely.

Now Elevate Your Brand with Our Custom Poly Mailer Bags

We work closely with you to design and produce mailers that aren’t just functional, they’re promotional tools. You can incorporate your logo, choose your brand colours, include promotional messages, QR codes, social media handles, or even get custom printed poly mailer bags to turn every shipment into a branded interaction.

Confused How to Customise? Don’t Worry! Pick From These Options 

Here are some of the common choices to customise your poly bags:

Choose Your Size

We manufacture poly mailers in a wide range of sizes from small packets for accessories to large bags for bulkier apparel or multiple items. Choose the size that fits your product and minimises wasted space while ensuring maximum protection.

Select Your Material

Our poly mailers are made using premium-quality materials such as Low-Density Polyethylene (LDPE) and High-Density Polyethylene (HDPE). For extra durability, we also offer co-extruded multi-layer films without sacrificing performance or visual appeal.

Writable Panel Options

Need to handwrite shipping information or mark contents on the go? Choose a writable panel finish. It’s a matte surface that allows easy writing with pens or markers.

Add Bubble Lining

Protect fragile or high-value items with internal bubble padding, seamlessly integrated within the mailer. This added cushion absorbs shock and prevents damage during handling, ideal for electronics, cosmetics, and delicate accessories.

Choose Your Finish

Select from a variety of surface finishes to enhance both the look and functionality of your mailers. Go for a matte finish for a modern, muted aesthetic, or a glossy finish to make your branding pop. We also offer metallic or pearlised finishes to elevate the unboxing experience.

Include a Return Strip

Simplify the returns process for your customers with a built-in second adhesive strip. Just seal, peel, and send back, no need for extra tape. It’s perfect for fashion retailers, subscription services, and brands offering flexible return policies.

Pick the Perfect Seal from Multiple Closure Styles

Choosing the right closure style is essential for secure and efficient shipping. At The Product Boxes UK, we offer several closure options to match your packaging needs. For a strong, tamper-proof seal, our permanent self-seal poly bags are ideal and widely used for single-use packaging. If you require more flexibility, our resealable adhesive closures allow customers to conveniently return products using the same mailer, making them perfect for fashion and subscription-based businesses. We also offer zip-lock and peel-and-seal options, which provide added convenience for repeated use or premium product deliveries. No matter your business model, you can select a closure style that enhances both security and customer satisfaction.

Make Your Brand Stand Out  With Logo, Barcode & More

Packaging is the first physical touchpoint between your business and your customer. Why settle for plain, generic mailers when you can print your company logo, barcode, branding colours, and even product images directly onto the bag? Our in-house design team helps bring your vision to life with advanced print techniques that support full-colour graphics, high-contrast designs, and waterproof inks.

Whether you’re shipping thousands of orders daily or sending a handful of curated boxes each week, customised printing increases brand recall and boosts customer loyalty. Let every shipment speak your brand language.

Make It Mailer Bags Pop with Eye-Catching Colour Choices

Your packaging should reflect your brand personality  and colour plays a powerful role in making your poly mailers memorable. We offer a full spectrum of custom colour options to match your brand identity. Whether you prefer sleek black, elegant white, vibrant shades, or pastel tones, we can produce poly mailers in virtually any colour you require.

With our advanced printing technology, every colour stays crisp, fade-resistant, and consistent across batches. Elevate your customer’s unboxing experience with colours that impress from the first glance.
