Poly Mailers

Poly mailers, also known as polythene mailing bags, provide a robust and weather-resistant option for e-commerce fulfilment. We manufacture these plastic shipping bags from a durable 50-micron LDPE film that resists tears and moisture during transit. The opaque material options ensure the contents remain private, while a strong self-adhesive strip allows for quick packing without needing extra tape. These poly bags for shipping are a practical choice for a wide variety of products, especially clothing and textiles.

Durable poly mailers and their features

Every poly mailer bag uses a single layer of 50-micron LDPE polythene film, offering a reliable barrier against dirt and water. The peel-and-seal adhesive flap creates a permanent, tamper-evident closure, securing items from dispatch to delivery.

Poly mailers personalized with your design

Businesses can create fully custom poly mailers to display their branding. The design process allows for printing on one or both sides of the bag. Choose a single Pantone spot colour for a simple logo or select a full-colour CMYK print for more complex, photographic designs. The film itself comes in several base colours, including standard white, black, or a clear finish. The online editor simplifies the process of uploading artwork and visualising the final design before placing an order. For a specific example of a printed bag, see the Custom Poly Mailer Bag product page. We supply these poly mailers personalized for brands of all sizes, with wholesale pricing available for larger quantities.

Poly bubble mailers for extra protection

For items that require more cushioning, our range includes poly bubble mailers. These soft shell poly bubble mailers incorporate a layer of bubble lining on the interior, providing protection against impacts for more delicate goods like jewellery or electronics.

Sizing and applications for poly mailing bags

Our collection of poly mailers in the UK covers a wide spectrum of sizes, from 17.5 x 25.5 cm for small accessories up to 45 x 55 cm for larger garments or multiple items. This range includes sizes that accommodate standard A4 and A3 documents or products. Their flexibility makes these poly bags for mailing suitable for soft goods that do not need rigid protection, such as t-shirts, books, and fabrics. They are a popular choice for fashion brands and are often used as mailing bags for Vinted sellers. For unbranded shipping, the Plain Poly Mailer Bag offers a simple and effective solution.
