Many brands, wholesalers and manufacturers in the US and Europe source their custom packaging bags from China. Working directly with a manufacturer can give you more structure options, better pricing and full control over printing — but only if the process is managed well.
This guide covers each step, from preparing your specifications to receiving your shipment.
Step 1: Prepare a Clear Specification
The more precise your request, the more accurate your quote. Prepare:
- Bag type – stand-up pouch, flat-bottom bag, three-side seal, zipper bag, poly mailer, roll stock, etc.
- Dimensions – width × height (+ gusset), in mm or inches
- Product and fill weight – what goes inside and how much
- Material or performance needs – barrier level, transparency, recyclability, puncture resistance
- Features – zipper, tear notch, valve, hang hole, window, spout
- Printing – number of colors, finish (gloss, matte, spot matte), number of designs (SKUs)
- Quantity per design and expected reorder frequency
- Destination market – US, EU, UK, etc. (affects compliance documents)

Step 2: Shortlist and Evaluate Suppliers
When comparing manufacturers, look beyond the unit price:
- Is it a factory or a trading company? A factory gives you direct communication with production.
- Product range – can they make the bag types and structures you need?
- Printing capability – gravure, flexo, digital (see Digital vs. Gravure Printing for Custom Pouches).
- Quality control – incoming material checks, in-line inspection, final inspection.
- Compliance documents – food-contact compliance relevant to your market, material safety reports.
- Communication – fast, clear replies in English and willingness to explain options.
- Factory evidence – photos or video of the workshop, video calls, or third-party audits.
Step 3: Request Samples
Always test before mass production:
- Stock samples – check material feel, zipper quality and seal strength.
- Fill test – put your actual product in the bag and check fit and appearance.
- Printed proof or pre-production sample – for color-critical brands.
Step 4: Finalize Artwork and Dielines
Your manufacturer should send a dieline (template) showing the bag outline, seal areas, zipper position and safe print area.
Artwork tips:
- Supply vector files (AI or PDF) with text converted to outlines.
- Use CMYK and specify Pantone colors for brand-critical elements.
- Keep text and barcodes away from seals, zippers and gussets.
- Leave space for regulatory information and future labelling requirements.
Approve a digital proof carefully — check spelling, barcodes, nutrition panels and colors before signing off.
Step 5: Confirm the Order Terms
Make sure your purchase order or proforma invoice clearly states:
- Specifications, quantities and unit prices
- Plate or cylinder costs (for gravure printing, these are usually one-time)
- Lead time for production
- Packing method (cartons, quantity per carton, pallets)
- Incoterms (EXW, FOB, CIF, DDP, etc.)
- Payment terms
- Acceptable quantity tolerance (flexible packaging orders commonly ship with a small +/- variance)
Step 6: Production and Quality Control
Typical production stages: printing → lamination → curing → slitting → bag making → inspection → packing.
Ask your supplier for:
- Photos or videos during production
- A final inspection report before shipment
- Retained samples from your batch
You can also hire a third-party inspection company for a pre-shipment inspection.
Step 7: Shipping and Delivery
| Method | Typical use |
|---|---|
| Express (DHL, FedEx, UPS) | Samples and small urgent orders |
| Air freight | Medium orders that are time-sensitive |
| Sea freight (LCL / FCL) | Larger orders, lowest cost per unit |
| Rail (to Europe) | Middle option between air and sea for some EU destinations |
Remember to plan for customs clearance, import duties and any tariffs that apply to your product category in your country.
Common Mistakes to Avoid
- Choosing purely on price without checking material specifications
- Skipping the fill test with real product
- Approving artwork without checking the dieline
- Not agreeing on color standards for repeat orders
- Ordering too close to your launch date with no buffer
FAQ
How long does custom packaging bag production take?
It depends on the printing method, structure and quantity. Digital printing is generally faster; gravure takes longer because cylinders must be made. Your supplier should give a clear timeline with each quote.
Can I order different designs in one order?
Yes. Many buyers combine several SKUs in one order. Digital printing is especially efficient for multiple designs.
What is the minimum order quantity?
Order quantities depend on the bag type, size and printing method. Contact us with your project details and we will suggest the most cost-effective option.
