Packaging Manufacturer: How to Evaluate a Supplier by 10 Criteria (Quality, Lead Times, MOQ, Print Control)
Choosing a packaging manufacturer based only on price is like buying equipment at the lowest rate without a warranty. In reality, a weak supplier “costs” more: defects on the production line, missed deliveries, fluctuating colors, reworks, complaints from retail chains, and excessive film consumption.
This article is a buyer’s guide: 10 criteria + a 0–5 scoring system to quickly filter out weak suppliers and keep 2–3 strong ones. At the end, you’ll find a ready-made list of questions and a brief for quotation.
Why choosing a supplier = fewer defects and losses, not just “price”
A bad supplier means:
- defects during packing (the film is “capricious”, seams are unstable, geometry varies);
- delivery disruptions and penalties/loss of shelf space;
- unstable printing: different shades from batch to batch, text “floats”;
- material overspending (you choose thicker film “just in case”);
- claims and reprinting of the batch.
Therefore, the selection logic should be like in professional procurement: quality / delivery / cost / compliance, not “like/dislike”.
10 criteria for evaluating a supplier
(formula: check → ask → request → red flags → score)
1) Materials and product suitability
Check: whether there is a choice of BOPP/CPP/PE and whether they can select thickness, transparency, barrier properties.
Ask: what types of BOPP are available (transparent/white/pearl/metallized/matte), what thicknesses.
Request: film/package samples + specification.
Red flags: “take what we have” without understanding the task.
Score 0–5: 5 = selection based on product/line/logistics, not “one film fits all”.
Practical reference: BOPP for flexo printing 15–40 microns; printing requires corona treatment, sealing requires a thermal layer (on one or both sides).
2) Seal quality and package construction (strength in real use)
Check: seam strength, resistance to tearing at corners, behavior in your logistics.
Ask: whether there are options for load (e.g., reinforced seam/puncture method to reduce defects).
Request: test batch/run on your line.
Red flags: “it works for everyone” without testing.
Score 0–5: 5 = provides testing and takes responsibility for results.
3) Geometry accuracy and repeatability (slitting/lanes/roll parameters)
Check: width, winding, edge quality, batch repeatability.
Ask: width tolerances, whether there is roll control (important for lines).
Request: roll specification + photos/videos of winding.
Red flags: no figures, only “we do quality”.
Score 0–5: 5 = clear tolerances + stable production.
4) Print control (color, text, stability in production)
Check: color consistency, readability of small text, contour clarity.
Ask: 6 or 8 colors, print width, how setup/approval works.
Request: approved standard (signed sample) + rules for design changes.
Red flags: printing without surface/activation requirements.
Score 0–5: 5 = process control and stability approach.
Maturity marker: mentioning process control in flexo printing (e.g., ISO 12647-6 as a reference for color/stability culture). Not necessarily certification, but a mindset indicator.
5) Technical capabilities for your product (perforation/ventilation/options)
Check: whether they can provide required ventilation and options.
Ask: film perforation (hot 1 mm), euro perforation 4–5 mm, technical holes 8 mm, euro slot, reinforcement.
Request: photo/diagram of hole pattern.
Red flags: “only one type of perforation”.
Score 0–5: 5 = selects diameter/quantity/location instead of “as usual”.
6) Production lead times and delivery reliability (SLA)
Check: predictability of lead times, queue planning.
Ask: how they handle peak seasons and force majeure.
Request: confirmation of deadlines after specification approval.
Red flags: “we’ll see”.
Score 0–5: 5 = transparent schedule + priority rules.
7) MOQ and entry threshold (especially for tests/new SKUs)
Check: minimum order quantities for film/bags and test feasibility.
Ask: MOQ separately for transparent/perforated/printed; bags separately.
Request: MOQ table + optimization options (e.g., testing on transparent film).
Red flags: only large volumes without alternatives.
Score 0–5: 5 = flexible for testing and scaling.
Reference (example of transparent policy):
- film: transparent from 20 kg; with perforation from 50 kg; with euro perforation from 50 kg; BOPP printed from 100 kg;
- flat bags: transparent from 20 kg; printed from 100/200 kg;
- cone bags: transparent from 20 kg; printed from 100/200 kg.
8) Technical support and communication speed
Check: ability to translate your product into technical parameters.
Ask: who manages the project (manager + technologist), response times.
Request: brief template.
Red flags: invoice without clarifications.
Score 0–5: 5 = asks the right questions and helps with specifications.
9) Documentation, traceability, supplier management
Check: specification, approved sample, change protocol.
Ask: how changes in formulation/design/parameters are recorded.
Request: sample specification and change log.
Red flags: “verbal agreement is enough”.
Score 0–5: 5 = documents and stores standards.
ISO 9001 logic: external suppliers must be evaluated and monitored proportionally to risk. Even without certification, “criteria → control → improvement” reduces risks.
10) Engineering flexibility and retail readiness
Check: options that improve sales and reduce defects.
Ask: euro slot + reinforcement tape, 8 mm technical holes, bottom sealing 8/10/15 cm, reinforced seam.
Request: examples.
Red flags: “only basic bags”.
Score 0–5: 5 = options tailored to task, not “one template”.
Technical capabilities (quick reference)
Insert this block into supplier comparison:
- Hot perforation: 1 mm hole; thickness 20–55 microns; width 250–1000 mm; up to 4 lanes.
- Euro perforation: 4–5 mm hole; thickness 20–80 microns; width 230–500 mm.
- Printing: up to 8 colors; width 300–1200 mm; roll-to-roll printing.

Checklist #1: Questions for supplier
- What material do you recommend and why (BOPP/CPP/PE)?
- What thicknesses are available (15–40 microns for BOPP/CPP; PE 25–100 microns)?
- Is corona treatment available? Is a sealing layer needed?
- Printing: 6 or 8 colors? width? how is approval done?
- How do you control color and small text?
- Film perforation: 1 mm and euro 4–5 mm — available?
- Technical holes 8 mm: limits/schemes?
- What are MOQ for film (20/50/100 kg) and bags (20/100/200 kg)?
- What are production lead times and how are deadlines confirmed?
- Can samples/test batches be provided?
Checklist #2: Data for quotation
To get a fast and accurate quote, provide:
- product and packaging format (roll/bag);
- material type (BOPP/CPP/PE), desired thickness;
- ventilation: perforation/euro perforation/technical holes;
- printing: number of colors, design/idea, transparency requirements;
- volume (kg) + deadline;
- logistics/storage conditions (temperature, humidity).
FAQ
1) Why does color “float” in production?
Most often due to weak process control: surface preparation (activation), ink/anilox settings, lack of reference sample and approval rules.
2) What is the difference between 6 and 8 color printing?
8 colors provide more flexibility for branding and shades, but process stability and quality control are more important than the number of colors.
3) What is the minimum order quantity (MOQ)?
Reference: film 20/50/100 kg depending on option; bags 20/100/200 kg (especially for printing). Always уточнюйте per configuration.
4) When is film perforation or euro perforation needed?
When the product releases moisture/gas and requires air exchange. Hot perforation (1 mm) is more delicate; euro (4–5 mm) is more intensive.
5) How to quickly test a new supplier with minimal risk?
Request samples/test batch, fix a reference sample, run a trial on your line, and evaluate consistency of printing/perforation.
The right flexible packaging supplier means stable production, fewer defects on the line, predictable lead times, and clear MOQ. If you go through all 10 criteria and calculate the score, you will almost certainly end up with 2–3 strong options — without a lottery.
