Apparel Shipping Bags

Custom Apparel Shipping Bags Heavy-Duty & Weatherproof Mailers for Clothing Brands

Sending clothes should not mean a waiting game for tears, water damage, or a dull unboxing experience. Staysure Packaging’s Apparel Shipping Bags are designed for UK fashion labels, boutique owners, and online retailers who want a piece of packaging that will hold its own with couriers but also looks good when it arrives. With high-quality film, a self-seal strip, and delivery across the UK, our parcels keep your clothes safe from warehouse to doorstep and with eco-friendly options available to suit brands working towards sustainability targets.

Each order you ship becomes a piece of your brand, not just a delivery. The packaging from the moment your customer receives their package to the moment they open it, conveys quality, care, and attention to detail. That’s why our Apparel Shipping Bags are strong enough to withstand the rigors of courier transportation and elegant enough to impress your customers.

Why UK Fashion & E-Commerce Brands Choose Staysure Apparel Bags

Superior Weatherproofing & Tear Resistance During Courier Transit

Apparel Shipping Bags are made with durable poly film that resists rain, moisture, and rough handling while in transit. Whether your garments are sorting through busy warehouses, left on a doorstep overnight, or tossed into a delivery van with heavier packages, they remain dry, wrinkle-free, and dust-free inside.

High-Tack Permanent Self-Seal Strip (Tamper-Evident Security)

Each bag is fitted with a high-tack, self-sealing strip that seals securely after use. Customers can instantly see what the parcel looks like when it’s been unwrapped. This ensures your customers are completely confident that their packages haven’t been opened during transit. It also provides your fulfilment team with a convenient, quick-seal solution that will help them pack at peak times.

Ultra-Lightweight Construction to Minimise Postal & Royal Mail Rates

Our mailers weigh far less than boxes, meaning brands using Royal Mail or another courier can slash their postage costs without sacrificing protection. Lighter packaging means lower shipping costs when sending large quantities of parcels over many weeks. Over time, you will find that simply the savings of postage alone can offset a significant proportion of your fulfilment costs.

Customisation Options: Turn Every Shipment into a Branded Unboxing Experience

Full-Colour Flexographic & Screen Printing

Print your logo, tagline, or social handles directly onto the bag with flexographic or screen printing. A branded mailer turns a simple box-delivery into a marketing touchpoint that will promote repurchases, unboxing videos, and organic social shares after the original purchase.

Material Choices: LDPE, Co-Ex Multi-Layer Film & 100% Biodegradable Poly

Choose from standard LDPE, our Co-Ex multi-layer film for heavier garments or biodegradable poly for brands who value sustainability, all of which are customisable to your product weight and shipping profile.

Custom Surface Finishes

Be different with your packaging. Go the extra mile with a matte soft-touch finish for a premium feel, a high-gloss finish for big branding, or write-on panels that make labelling and return handling easier for your warehouse staff.

Standard Sizes & Dimensions for Apparel Packaging

When buying the right size mailer for your order, you can save on shipping costs and avoid the garment shifting inside the bag. 6″ x 9″ mailers are ideal for single t-shirts or small accessories, while 9″ x 12″ bags are appropriate for standard folded shirts and tops. For activewear items or multiple items, choose the 10″ x 13″ size. Hoodies, sweatshirts, and denim go well in our 12″ x 15.5″ bags, and bulk coats or heavyweight winter wear would fit in one of our largest 14″ mailers.

Single Garment Mailers (T-Shirts, Activewear & Tops)

Sized for individual items, these bags are designed to allow for the smallest amount of free space in the bag so shipping weight and cost are as low as possible.

Multi-Item & Heavyweight Bags (Hoodies, Denim & Winter Wear)

Reinforced seams and thicker film hold heavier weights like jeans, hoodies, and winter jackets without splitting in any circumstances.

Returnable Shipping Bags with Dual Adhesive Peel-and-Seal Strips

By including two adhesive strips, the customers can reuse the bag for returns, making the customer experience even better and helping to achieve circular packaging goals.

Eco-Friendly & Sustainable Clothing Mailers (Zero-Plastic Goals)

Recycled Poly Mailers (PCR Materials)

Made from recycled post-consumer materials, these mailers save virgin plastic while retaining the same strength and sealing abilities of standard bags.

Compostable Sugarcane & Cornstarch Shipping Bags

For brands seeking to achieve zero-plastic packaging, our compostable range disintegrates naturally, providing the ability to achieve your sustainability goals without sacrificing its strength during transportation.

Apparel Shipping Bags vs. Standard Shipping Boxes: Which Is Right for You?

Poly mailers are lighter, easier to ship, and take up less storage space than boxes — ideal for soft, flexible products such as t-shirts, hoodies, and activewear. They also flex to fit product, rather than leaving space open for the courier to fill, which reduces volumetric weight charges. Boxes, by contrast, are a better choice for rigid, fragile, or expensive merchandise that needs extra protection. For most apparel companies, but, Staysure’s shipping bags offer the best combination of protection, cost-effectiveness, and streamline warehouse packing for streamlined items.

No matter what size or finish, your Staysure Apparel Shipping Bag will protect your clothing, your brand, and your shipping costs — from the first mile to the final delivery. Read more: Custom T-Shirt Boxes
