Five sizes. Fifty bags. The variety pack that covers every order you ship.

From compact 6×9" accessories parcels to large 14×19" clothing bundles — one pack handles the full range without you holding multiple separate packs or oversizing your bags.

Whether you're just starting to sell online, dispatching occasional orders from home, or need a practical top-up stock that covers unusual sizes, this mixed grey mailing bag set gives you 10 bags in each of five sizes — including the large 14×19" option that most starter packs don't include.

Unlike single-size packs, this variety set flexes around what you're actually shipping. Small jewellery orders go into the 6×9". Folded tops and hoodies into the 10×14" or 12×16". Larger soft goods and bulkier bundles into the 14×19". You're covered without overspending or overstocking.

Each bag is made from robust 60-micron opaque polythene film — strong enough for postal and courier handling, light enough to keep your parcel weight down. The permanent peel-and-seal strip closes in seconds and stays closed: the only way in is to tear the bag, making tampering immediately obvious at delivery.

At 10 bags per size, this is a sensible pack for lower-volume dispatchers and sellers who want variety over bulk. For higher-volume dispatch across four core sizes, our 100-pack mixed grey mailing bags may suit you better.

Features and benefits

• 5 sizes including 14×19" — covers bulky soft goods and larger clothing items that the standard 4-size pack doesn't reach
• 10 bags per size, 50 total — practical quantities for lower-volume or varied dispatching without over-ordering
• 60-micron opaque polythene film — strong enough to survive postal sorting; light enough to minimise added parcel weight
• Permanent self-adhesive peel-and-seal closure — seals in one motion with no tape, moisture, or tools
• Tamper-evident design — the bag must be torn to open; interference is visible immediately on delivery
• Water and dirt resistant — contents stay dry and protected through the full postal journey
• Lightweight construction — keeps added parcel weight minimal, helping contain postage costs
• Professional opaque grey finish — clean appearance suitable for business and personal dispatching alike

Technical specifications

Frequently asked questions

How many bags of each size are included?
The pack contains 50 bags split equally: 10 × 6×9", 10 × 9×12", 10 × 10×14", 10 × 12×16", and 10 × 14×19".

What is the largest bag in this pack?
The 14×19 inch (356×483mm) bag is the largest size here. It's well suited to bulky clothing, folded soft furnishings, and larger soft goods that don't fit comfortably in a 12×16" bag.

What types of items can I send in these bags?
Clothing, accessories, books, cosmetics, stationery, gifts, and other non-fragile items are all suitable. The bags are not padded or rigid, so fragile contents should be wrapped separately before bagging.

How does the self-seal closure work?
Peel back the adhesive strip along the top flap, fold it down, and press firmly. The bond is permanent — the bag can't be reopened without visibly tearing it, making any tampering obvious to sender and recipient alike.

Is this pack suitable if I only send occasional parcels?
Yes — 10 bags per size suits lower-volume dispatching. You get useful coverage across five sizes without the larger per-size quantities found in 100-pack options.

Are the bags recyclable?
The bags are made from polythene (polyethylene), which is accepted at many UK supermarket soft plastic recycling collection points. Check your local scheme for guidance.

Frequently Asked Questions

What does 57x40mm mean?

57 mm is the width of the paper; 40 mm is the outer diameter of the roll. Both measurements must match your card machine's paper compartment. This is one of the most common sizes for PDQ terminals and small card readers in the UK.

Are these rolls compatible with Clover Flex / Verifone / Ingenico?

Yes — these rolls are designed to fit the card terminals listed above. Always cross-check the width (57 mm) and diameter (40 mm) with the specification in your terminal's manual to be certain.

Do these rolls contain BPA?

No. iSOUL till rolls are manufactured from BPA-free thermal paper, making them safe to handle and suitable for recycling.

How do I know when a roll is nearly finished?

Each roll has a red warning strip near the end. When pink or red colouring appears on your receipts, it is time to replace the roll — this gives you a moment to swap it before the roll runs completely empty.

Can I buy in bulk for my business or to resell?

Yes. Pack sizes go up to 1,000 rolls. If you need a recurring supply or would like to discuss wholesale pricing, please contact us via the details in the footer or the Become a Reseller page.
