Key takeaways
- Custom compostable mailers are made to order — each run is created specifically against your brief, not picked from pre-made stock.
- The process follows a defined sequence: enquiry → specification → artwork → quote acceptance → production → delivery.
- Lead time is typically 8–12 weeks from artwork approval — the clock starts after artwork is confirmed, not at enquiry.
- MOQ exists because setup costs are fixed regardless of run size — it is a manufacturing reality, not a sales barrier.
- You do not need final artwork or exact dimensions to begin — estimates are enough to start a useful conversation.
Made to order, not off the shelf
The defining characteristic of custom compostable mailers is that they are made to order. There is no warehouse of pre-made branded mailers waiting to be picked and shipped. Each production run is created against a specific brief: your dimensions, your artwork, your material specification, your quantity. The mailers that arrive are uniquely yours.
This separates custom packaging from stock packaging. Stock packaging can be ordered quickly in small quantities. Custom packaging requires setup — your artwork is calibrated to print, your dimensions are tooled, your material is sourced for your run. That setup has a fixed cost regardless of run size, which is why minimum order quantities exist. For the full explanation of MOQ and when it makes commercial sense, see the What MOQ Means in Custom Packaging guide.

This article focuses specifically on how the process works from enquiry to delivery.
The process from enquiry to delivery
The custom compostable mailer process follows a consistent sequence. The table below maps each step, what happens, who is responsible, typical timing, and the most common source of delay at each stage.
| Step | What happens | Who is responsible | Typical timing | Common delay |
|---|---|---|---|---|
| 1. Enquiry | Dimensions, volumes, print intent, timeline, delivery country shared | Brand / buyer | Week 1 | Incomplete brief — missing dimensions or volume estimates |
| 2. Quote & specification | Zero Pack issues an indicative quote; specification is confirmed in detail | Zero Pack + buyer | Weeks 2–3 | Revisions to dimensions or print spec after initial quote |
| 3. Artwork preparation | Brand supplies assets; Zero Pack design support prepares print-ready files if needed | Brand / Zero Pack design | Weeks 3–5 | PNG-only logos, missing Pantone or HEX references, late designer response |
| 4. Proof & approval | Digital proof issued; buyer reviews and approves artwork | Buyer | Week 5 | Multiple revision rounds; delayed approval response |
| 5. Production | Manufacturing begins after written artwork approval; run is produced | Zero Pack / manufacturer | Weeks 5–13 | Manufacturing schedule constraints; specification change after approval |
| 6. Freight & delivery | Completed stock is shipped by air or sea to specified delivery address | Zero Pack / freight partner | Weeks 11–15 (air) / 13–17 (sea) | Port delays, customs hold, incorrect delivery address |
A first-order timeline: what to expect week by week
For a brand placing a first order, the realistic week-by-week timeline from initial enquiry to stock arrival looks like this.
- Week 1: Initial enquiry submitted — dimensions estimate, volume estimate, print direction, delivery country, required-by date.
- Weeks 2–3: Indicative quote issued; specification confirmed; any revision to dimensions or print agreed.
- Weeks 3–5: Artwork preparation — brand supplies assets; Zero Pack design support prepares print-ready files if needed.
- Week 5: Proof issued and approved. Written approval triggers production.
- Weeks 5–13: Production — the mailers are manufactured to your specification.
- Weeks 11–15: Freight and delivery — air freight is faster and more expensive; sea freight is slower and more cost-effective for larger orders.
The three specification decisions that shape everything
Size, print, and material are the three decisions that drive the rest of the specification process. Getting clarity on all three before enquiring accelerates quoting significantly.
Size is driven by your actual products in their packed state. Measure your most commonly dispatched products, add 30–50 mm clearance for the adhesive closure, and that is your working estimate. Print complexity matters more than first-time buyers expect — single-colour print has different economics from full-coverage artwork. Material specification determines what compostability certification applies. Home compostable and industrial compostable materials have different certifications and different implications for customer disposal guidance.
None of these decisions need to be finalised before enquiring. Estimates and approximations are enough to begin. What helps is a rough sense of each — 'approximately 350 × 450 mm internal', 'our logo in white on a dark background', 'home compostable preferred if possible'. For the full artwork preparation guide, see How to Prepare Artwork for Custom Mailers.
What to have ready before enquiring
You do not need finalised artwork, exact dimensions, or a precise order quantity to begin. Estimates are enough. The information that produces the most useful initial quote: your website URL or brand references; approximate mailer dimensions based on your most common products; estimated monthly order volume; print intent (logo-only, multi-colour, or full coverage); delivery country; and the date you need packaging by.
Free design support is available if your brand assets are not yet print-ready. A PNG logo, HEX colour codes, and a sense of the layout you want is enough to begin. Zero Pack can prepare artwork to production standards as part of the quoting and approval process. The starting point is the custom compostable mailers enquiry page.
