Whether you're dispatching clothing, documents, magazines or small parcels, the right packaging makes all the difference. At Pixartprinting, our custom plastic mailing bags combine durability, practicality and professional branding in one affordable solution. Available in six formats, with printing on the front only or on both sides, our plastic postage bags are designed to protect your contents and promote your brand with every delivery — from just 200 copies, with free delivery, always.

Plastic Mailing Bags Built for UK Businesses

In today's fast-paced e-commerce environment, plastic postage bags have become an essential packaging solution for UK businesses of all sizes. Lightweight yet robust, our plastic mailing bags are designed to hold important documents comfortably, or to ship a wide range of items including clothing, small boxes, magazines and catalogues. Their waterproof construction ensures your contents arrive in perfect condition regardless of the weather — a must for any business shipping across the UK.

Made from low-density polyethylene (LDPE), our bags feature a white outer layer and a black inner layer, guaranteeing complete privacy for your contents at all times. Whether you're a small independent retailer or an established brand, our plastic shipping bags offer a reliable, professional and cost-effective way to get your products to your customers.

Plastic Shipping Bags for E-Commerce

For small businesses and online retailers, every customer interaction is an opportunity to reinforce your brand. Our custom plastic shipping bags let you do exactly that — turning an everyday postage bag into a branded touchpoint that leaves a lasting impression. With a minimum order of just 200 copies and competitive pricing, our plastic mailing bags are an accessible and impactful solution for businesses at every stage of growth. Print your logo, brand colours or a promotional message directly onto the bag and make sure your packaging is as professional as the products inside.

Durable and Waterproof Polyethylene

Our plastic mailing bags are made from low-density polyethylene (LDPE) — a waterproof, durable and affordable material that is well suited to postal and shipping applications. LDPE is customised using flexography, a high-quality printing technique that produces sharp, consistent results on flexible materials. The two-layer construction — white on the outside, black on the inside — ensures that the contents of your plastic postage bags remain completely private throughout transit. LDPE is also a recyclable material, making it a responsible choice for businesses mindful of their packaging footprint.

Six Formats to Suit Every Shipping Need

We offer our plastic shipping bags in six practical formats, giving you the flexibility to choose the right size for your products:

• 17 x 25 cm — ideal for documents, small accessories and flat items.
• 25 x 35 cm — a versatile mid-size option for folded garments, booklets and small gifts.
• 30 x 40 cm — well suited to magazines, catalogues and medium-sized clothing items.
• 35 x 45 cm — perfect for bulkier clothing, larger publications and multi-item orders.
• 40 x 50 cm — our largest standard format, ideal for oversized or bulky shipments.
• 35 x 45 cm with die-cut handle — combines the practicality of a mailing bag with the convenience of a carry handle, perfect for in-store collections or click-and-collect services.

Make Your Plastic Postage Bags Your Own

Our plastic mailing bags can be printed on the front only, or with the same design on both the front and back — giving you maximum flexibility when it comes to showcasing your branding. Choose from a curated selection of PANTONE® colours to ensure your brand identity is reproduced with precision and consistency:

• PANTONE® Black
• PANTONE® Blue 072 C
• PANTONE® 186 C
• PANTONE® 341 C
• PANTONE® Orange 021 C
• PANTONE® Cool Gray 8 C
• Custom PANTONE® — add your chosen colour directly to your artwork file (limited to swatches within the PANTONE+ Solid Coated range).

Whether you opt for a bold, single-colour logo or a more detailed branded design, our flexographic printing process ensures a clean and professional finish on every bag.

Custom Plastic Mailing Bags for Clothing and Fashion Retail

For clothing retailers and fashion brands, plastic mailing bags are one of the most practical and widely used packaging solutions available. Our bags are lightweight enough to keep postage costs low while being robust enough to protect garments from moisture and damage in transit. The larger formats — 35 x 45 cm and 40 x 50 cm — are particularly well suited to folded clothing items, while the die-cut handle option adds a premium touch for in-store or collection orders. Add your brand logo, seasonal messaging or care instructions directly to the bag to create a cohesive unboxing experience that reflects the quality of your products.

Plastic Mailing Bags with Your Logo

Every package you send is an extension of your brand. Custom printed plastic postage bags with your logo are a simple yet highly effective way to increase brand visibility and build recognition with every order you ship. Unlike plain brown boxes or unbranded polythene bags, a custom printed plastic mailing bag communicates professionalism and attention to detail from the moment it lands on your customer's doorstep. With Pixartprinting, achieving a polished, branded result is straightforward and affordable — regardless of the size of your business.
