If you've tried to order custom printed polymailers in the UK recently, you've probably encountered this: you find a supplier, ask for a quote, and discover the lead time is anywhere from two to six weeks. Sometimes longer.
For an e-commerce brand running low on stock — or anyone with a real deadline — that's a problem.
So why do custom polymailers take so long? And is it actually possible to get them faster? Here's the honest answer to both questions.
The Traditional Custom Polymailer Supply Chain
To understand the lead time, you need to understand how most custom polymailers sold in the UK are actually made.
Step 1: Artwork and Plate Setup
Traditional polymailer printing uses flexographic printing — a process that requires a physical printing plate for each colour. Creating these plates takes 3-5 working days and costs money, which is passed on in the form of minimum order quantities and setup fees. Digital printing, by contrast, requires no plates at all.
Step 2: Overseas Manufacturing
Here's the big one. The majority of custom polymailers sold in the UK — even those sold by British companies — are manufactured in China, Vietnam, or Eastern Europe. Why? Because manufacturing costs overseas are significantly lower.
The problem is the timeline. Manufacturing the bags takes 7-14 days. Sea freight from China takes 3-5 weeks. Even air freight takes 5-7 working days. By the time your order lands in the UK, you've already waited three to five weeks.
Step 3: UK Import Processing
Customs clearance, UK delivery, quality inspection — add another 3-5 working days. Your total elapsed time from order to arrival: 4-8 weeks, depending on the supplier, the size, and the time of year.
Step 4: Your Delivery
Once the bags are in a UK warehouse, you're finally in the home stretch. Standard UK delivery adds 1-2 working days. If you're lucky, you've waited four weeks. If you've hit a Chinese holiday or a shipping delay, you might be waiting six.
Why The Craftionals Is Different
The Craftionals express service operates on a fundamentally different model.
UK-Based Production
Rather than sourcing from overseas, The Craftionals produces express polymailers in the UK. This eliminates the manufacturing-to-UK leg of the supply chain entirely — and with it, the biggest source of delay.
Digital Printing — No Plates, No Setup Time
Digital printing technology means there are no printing plates to manufacture, no setup queue, and no minimum job time before your order can start. Once artwork is approved, production can begin immediately.
No Batching Queue
Many suppliers run a batch model: they collect multiple orders, group them together for cost efficiency, and print them in a single run. Your order might be ready to print on Monday, but if the batch doesn't run until Thursday, you wait. The Craftionals express service doesn't batch — your order goes to production independently.
Transparent Timelines
When we say 4-7 working days from artwork approval, we mean it precisely:
- The clock starts when you approve your proof — not when you place the order, not when we receive payment
- Working days means Monday to Friday, excluding UK bank holidays
- Delivery is included — so 4-7 working days from approval is when the bags arrive at your door, not when they leave our facility
What "4-7 Working Days" Looks Like in Practice
Let's be specific. Here's a realistic example of an express polymailer order timeline:
Day 0 (Monday): You submit your enquiry with your artwork file (PDF or JPEG).
Day 1-2 (Tuesday/Wednesday): We send your free digital proof. You review it and send your approval.
Day 2-6 (Wednesday–Monday): Production runs. Your polymailers are printed, quality checked, packed, and dispatched.
Day 4-7 (Thursday–Tuesday): Your order arrives at your door via free UK delivery.
From first contact to delivery: 5-8 calendar days in most cases. That's the real-world timeline.
Addressing Buyer Scepticism
We understand that "4-7 working days" can sound like marketing language — especially if you've been burned by a supplier who quoted a lead time and then missed it. Here's what makes this different.
It's from artwork approval, not from order placement. This matters because the only variable you don't control is how quickly you approve your proof. The production timeline is fixed once approval is received.
There's no overseas leg. The typical source of missed lead times is shipping delays — a container that's late, a port that's busy, a customs clearance that takes longer than expected. Because express orders are produced in the UK, none of these variables apply.
The 35% premium is the mechanism. Express orders are priced at 35% above our standard rates. This isn't arbitrary — it reflects the cost of prioritised production scheduling and dedicated capacity. If we couldn't reliably deliver within the quoted timeframe, we couldn't justify the premium.
You can track progress. If your order is approaching the 7 working day mark and you haven't received a dispatch notification, contact us directly via WhatsApp. We don't hide from follow-up questions.
When Express Polymailers Make Financial Sense
Express pricing is 35% higher than standard. For most businesses, that's a meaningful cost difference. Here's a simple framework for deciding when express is worth it.
Use express if:
- You've run out of stock and the lost sales from delayed fulfilment outweigh the express premium
- You have a fixed launch date and the cost of missing it exceeds the express premium
- You've been let down by your usual supplier and need a reliable alternative quickly
- You want to test a new design before committing to a large standard order
Use standard if:
- You have 3+ weeks before you need stock and no pressing deadline
- You're ordering large quantities where the 35% premium is a significant absolute cost
- You're reordering a design you've already approved and tested
Getting Your Artwork Ready
The fastest way to minimise your total lead time is to have print-ready artwork when you contact us. Here's what that looks like for polymailers:
- Format: PDF (vector, preferred) or JPEG (300dpi minimum)
- Colour: One colour (white, black, or your chosen brand colour)
- Size: Know which of the three sizes you need — 22×36cm, 29×48cm, or 40×60cm
- Bleed and safe zones: Our team will flag any issues in the proof stage, so don't worry if your artwork isn't perfectly set up
If you don't have print-ready artwork, we can often work from a logo file. Our proof team will adapt it for print and send you a proof to approve.

Frequently Asked Questions
How fast can I get custom printed polymailers in the UK?
The Craftionals delivers custom printed polymailers in 4-7 working days from artwork approval — the fastest available from any UK-based supplier. This compares to the industry standard of 10-15 working days, or 4-6 weeks from suppliers who manufacture overseas.
What does '4-7 working days from artwork approval' actually mean?
It means the 4-7 working day clock starts when you approve your digital proof — not when you place the order. We send your free digital proof within 24-48 hours on weekdays. So from first contact to delivery, you're typically looking at 6-10 calendar days.
Are express custom polymailers lower quality than standard?
No. Express polymailers are produced on the same equipment, to the same specification, using the same materials as standard orders. The only difference is the production schedule — express orders are prioritised in the queue.
What sizes are available for express custom polymailers?
Our express custom polymailers are available in three sizes: 22×36cm, 29×48cm, and 40×60cm — the same sizes as our standard polymailer range.
