Why Coloured Mailing Bags Are Growing in UK E-Commerce in 2026
Colour has become a powerful part of packaging in the UK. With social shopping, TikTok unboxing videos and small boutique businesses increasing across the country, sellers are using colour to create a memorable delivery experience. Grey mailing bags remain the strongest and most common choice, but coloured mailing bags have become a branding tool for clothing shops, homeware sellers, beauty brands and gift stores. Our full Mailing Bags range now includes pink, purple, blue and green options for businesses that want a more distinctive look while keeping strong film quality.
What Are Coloured Mailing Bags?
Coloured mailing bags are the same strong polymer mailing bags used across UK eCommerce, simply produced with different pigments. They remain lightweight, waterproof, recyclable and tamper-evident. All Mr Bags coloured mailing bags use 60 µm film, giving the same durability as our grey range. The colour you choose does not weaken strength. Each colour option—pink, blue, green and purple—is available in four core sizes: 10×14″, 12×16″, 15×18″ and 17×22″.
Are Coloured Mailing Bags as Strong as Grey Mailing Bags?
Yes. All our coloured mailing bags use tough 60 µm co-extruded film, offering excellent tear resistance, water protection and fully opaque coverage. The choice between grey and coloured mailing bags is not a strength decision—it is a branding decision. Businesses that want discreet, professional packaging tend to choose grey, while brands that want personality and memorability choose colour.
Why Online Sellers Use Coloured Mailing Bags in 2026
Colour is becoming a major part of UK eCommerce branding. Boutique sellers, fashion brands, handmade creators and subscription box companies increasingly use coloured mailing bags to create a recognisable parcel. Influencer orders, seasonal packaging (Mother’s Day, Christmas, Valentine’s Day) and small independent stores benefit from presentation that stands out from standard grey bags. Royal Mail Tracked 24/48 and courier services all accept coloured mailing bags without issue, provided the address area is clear and labels are firmly applied.
Pink Mailing Bags: Popular for Beauty, Clothing & Gifts
Pink mailing bags are one of the strongest trends in the UK small business sector, especially for beauty, fashion and accessories. The colour stands out immediately on arrival, making it ideal for boutique parcels, subscription gifts and social media branding. Our Pink Mailing Bags range is available in every core size, including the popular 17×22″ option. For retailers wanting a larger statement bag, the Pink 17×22″ Mailing Bag is ideal for coats, knitwear and bulk orders.
Purple Mailing Bags: Boutique, Luxury & Premium Branding
Purple mailing bags offer a richer, more premium appearance that suits boutique fashion, handmade items, high-end gifting and seasonal campaigns. The colour provides a luxury presentation while keeping the same recyclable 60 µm strength as grey bags. Our Purple Mailing Bags collection includes all four core sizes, with the 15×18″ Purple Mailing Bag being one of the most popular for clothing sellers.
Green Mailing Bags: Clean, Soft & Eco-Friendly Style
Green mailing bags give a fresh, natural look many UK eco-led brands prefer. While they are not biodegradable, the colour provides a soft, earthy appearance that works well for skincare, home goods and handmade sellers. All four sizes are available in the green range. Many customers choose the Green 12×16″ Mailing Bag for mid-sized clothing, books and textiles.
Blue Mailing Bags: Professional, Corporate & Clean Branding
Blue mailing bags are often used by small corporate sellers, tech accessory shops and uniform suppliers. The colour feels clean, practical and trustworthy, offering a middle ground between plain grey and bright colours. The Blue Mailing Bags collection includes every size, and the 10×14″ Blue Mailing Bag is especially popular for clothing and eCommerce packs.
Which Sizes Do Coloured Mailing Bags Come In?
All four colours—pink, blue, green and purple—are available in the same core sizes:
- 10×14″ – clothing, A4 documents, small parcels
- 12×16″ – hoodies, jeans, books, mid-sized parcels
- 15×18″ – jackets, textiles, multiple clothing items
- 17×22″ – bulkier apparel, blankets, large deliveries
This makes it easy for sellers to match size and colour without changing protective quality. If unsure, our mixed-size pack across each colour offers 100 bags from 10×14″ up to 17×22″.
What Can You Ship in Coloured Mailing Bags?
Coloured mailing bags suit the same products as standard grey mailing bags. Popular examples include:
- Clothing: tees, jeans, hoodies, jackets
- Beauty and accessories
- Gifts and subscription boxes
- Home textiles and soft furnishings
- Small boxed items
- Handmade goods
The Peel & Seal closure keeps items secure during Royal Mail and courier processing, while the fully opaque film protects privacy.
Royal Mail & Courier Suitability for Coloured Mailing Bags
Coloured mailing bags are fully accepted by Royal Mail, Evri, DPD and all major UK couriers. The colour has no impact on processing or delivery. You still need to follow standard parcel rules such as correct sizing and clear labelling, as set out in the Royal Mail size and weight guide. The key requirements are the same as grey mailing bags:
- Address label must be clear and scannable
- Bag must be sealed using the Peel & Seal strip
- Parcel must be flexible enough for sorting machines
- Film must be opaque (all colours meet this)
60 µm co-extruded film ensures coloured bags stay strong in rain, snow and transport. Most sellers use bright colours for customer-facing parcels and grey for internal warehouse dispatch, but both work equally well for Royal Mail Tracked 24/48.
Branding Tips: How to Use Coloured Mailing Bags Effectively
Colour can increase brand memorability when used correctly. Here are simple ways UK sellers use coloured mailing bags in 2026:
- Match colours to product type – pink for beauty, blue for corporate items, green for eco-themed goods, purple for luxury.
- Create seasonal editions – pink for Valentine’s Day, purple for Christmas gifts.
- Use colour as an inner presentation layer – many sellers pack items in a coloured bag and use a grey outer Grey Mailing Bag for delivery strength.
- Add brand stickers to improve perceived value.
Colour can help your business create an instantly recognisable parcel without increasing packaging costs.
Environmental Factors: Are Coloured Mailing Bags Eco-Friendly?
Coloured mailing bags from Mr Bags are fully recyclable, just like grey bags. They are made from strong LDPE film which can enter many local recycling streams depending on council guidance. Soft plastics and plastic bags are now widely collected at supermarkets and specialist points across the UK; you can check guidance on sites such as Recycle Now or your local council.
Brands looking to maximise eco messaging often pair coloured bags with Paper Bags for in-person retail or gifting, and use coloured mailing bags for online delivery.
Internal Packaging Combinations for Better Protection
Many businesses combine inner packaging with coloured mailing bags for improved stability and presentation. For example, using a small inner bag or tissue wrap before placing the parcel inside a coloured mailing bag can enhance customer experience. For heavier items, pairing with Cardboard Boxes gives additional strength.
Coloured mailing bags also work well with printed inserts, gift cards and branded tape, which can be sourced from our Packaging Tape collection.
How to Choose the Right Colour for Your Brand
Selecting a colour should be guided by your industry, customer base and brand personality. Here are simple guidelines:
- Pink: beauty, skincare, jewellery, boutique clothing
- Purple: luxury, gifting, handmade goods
- Green: eco-inspired products, wellness, home goods
- Blue: corporate items, tech accessories, uniforms
All four colours work across standard product categories and sizes. The choice often comes down to how you want customers to feel when they see the parcel.
Mistakes to Avoid When Buying Coloured Mailing Bags
- Choosing bags that are too small – leading to bursting or overfilling.
- Buying very thin bags – anything under 55–60 µm risks tearing.
- Using colour without considering your brand identity.
- Not testing label adhesion – always press firmly on coloured film.
- Using colour for returns when grey is more discreet.
Avoid these common issues to ensure strong, repeatable packaging quality.
Are Coloured Mailing Bags Good for Returns?
Yes. Many UK sellers use coloured mailing bags for returns as well as outbound orders. A bright pink or purple parcel is easy to spot in a returns cage or stockroom, which can help your team process items faster. Some retailers prefer using grey for returns to keep things more discreet, but there is no operational drawback to using colour as long as the film is strong and the label is clear.
Buyer’s Guide: Which Coloured Mailing Bag Should You Choose?
Here is a clear guide for selecting the right colour and size for your business:
- Best for small clothing and gifts: 10×14″ in any colour.
- Best for mid-size fashion: 12×16″ green or purple.
- Best for jackets and multi-item orders: 15×18″ purple or blue.
- Best for bulky apparel: 17×22″ pink or blue.
If unsure, our mixed packs are ideal for testing. They include 100 bags from 10×14″ to 17×22″ across your chosen colour.
