How to evaluate printing and packaging companies for packaging projects

What buyers are really comparing

Choosing between printing and packaging companies should not start and end with the lowest unit price. The better question is whether a supplier’s materials, print process, finishing equipment, compliance controls and commercial terms match the risk profile of the job. A short-run promotional carton, a food-contact pouch, an export corrugated shipper and a premium rigid box all need different production logic. This Buyer’s Guide explains how to build a shortlist, what evidence to request, and where buyers often underestimate cost or production risk.

The market context also matters. Packaging print is no longer a narrow print-buying category. Smithers reported that the printed labels and packaging market was valued at $517.9 billion in 2024 and forecast it to reach $618.2 billion in 2029 at constant 2023 pricing. Its analysis also notes higher automation, wider digital adoption and brand-owner pressure for more sustainable packaging. (smithers.com)

Start with the packaging format before asking for quotes

A common sourcing mistake is asking several companies to quote before the package structure is defined. A printer that performs well on labels may not be the right partner for laminated flexible packaging. A corrugated converter may handle shipping cartons efficiently but outsource specialty finishing. A folding-carton producer may offer strong offset printing and die-cutting but have limited barrier-material capability. The buyer’s first task is to define the job as a manufacturing specification, not only as artwork.

At minimum, prepare the following before contacting suppliers:

• Packaging format, such as label, folding carton, corrugated box, flexible pouch, sleeve, insert, rigid box or display.
• Substrate requirements, including paperboard grade, corrugated flute, film structure, foil, coating, varnish or recycled-content target.
• Print process expectations, such as flexographic, offset litho, gravure, digital inkjet, toner or hybrid production.
• Finishing needs, including lamination, die-cutting, hot foil, embossing, window patching, gluing, pouch making or kitting.
• Regulatory exposure, especially food contact, cosmetics, pharmaceuticals, child safety, transport testing or claims such as FSC.
• Order profile, including launch quantity, annual volume, number of SKUs, repeat frequency and expected artwork changes.

Smithers identifies flexographic printing as the largest packaging and label print segment by both volume and value, while digital printing is mainstream in labels and increasingly used in corrugated packaging and cartons. Buyers therefore should not ask whether digital or flexo is better in general. They should ask which process fits the run length, substrate, color requirements and change frequency of the specific project. (smithers.com)

Quality systems separate capable suppliers from risky suppliers

Packaging defects are costly because they can stop packing lines, force relabeling, delay retail launches or create compliance exposure. Supplier evaluation should therefore focus on how variation is prevented, not only on whether a sales sample looks good. Ask how files are preflighted, how color is measured, how approved proofs are controlled, how press checks are documented, and how nonconforming material is quarantined.

For color and print control, ISO 12647 is a useful reference point. ISO says ISO 12647-1 defines primary process-control parameters for half-tone color separations, proofing and production prints, and the 2013 edition was reviewed and confirmed in 2024. A company does not need to turn every sales conversation into an ISO discussion, but it should be able to describe its measurable color workflow in practical terms. (committee.iso.org)

Strong suppliers usually give clear answers to these questions:

• Who owns structural engineering, prepress and proof approval?
• Which tolerances apply to board caliper, film thickness, color, barcode grade, glue strength and dimensions?
• Are first-article inspections and retained samples standard practice?
• How are material lots and production batches traced?
• What corrective-action process is used if defects are found after delivery?
• Which parts of the job are subcontracted, and how are subcontractors controlled?

Buyers should be cautious when a supplier treats proofing as a formality. A soft proof can confirm content and layout, but it cannot fully verify color, texture, opacity, varnish, embossing or fold performance. For complex retail packaging, request a production-like sample or a clearly defined prototype stage before approving mass production.

Compliance requirements can change the shortlist

Printing and packaging companies often serve several end markets, but not every plant is suitable for regulated or sensitive products. Food, beverage, cosmetics, pharmaceuticals and children’s products usually require more documentation than general promotional packaging. Even when the converter is not responsible for final product labeling, it may still be responsible for inks, coatings, adhesives, films, paperboard and process controls that affect safety or legal claims.

In the United States, the FDA explains that a food contact substance can include packaging and packaging components, as well as adhesives, colorants and other substances used on packaging surfaces. If a food contact substance is considered a food additive, it must be authorized for that intended use before it is marketed in the U.S., usually through a food contact notification process. (fda.gov)

BRCGS Packaging Materials is another qualification signal for packaging suppliers, especially in food-related supply chains. BRCGS states that its Packaging Materials standard helps sites demonstrate that products are quality assured, legally compliant and authentic, and that the standard applies to operations producing packaging materials for conversion or printing. (brcgs.com)

For paper and paperboard sustainability claims, FSC chain-of-custody certification is not simply a logo preference. FSC says companies involved in transforming, processing, manufacturing or distributing forest-based products must be FSC-certified to sell products with an FSC logo or FSC claim; its eligibility list includes printing companies and print brokers that take legal possession. (us.fsc.org)

Sustainability claims need evidence, not slogans

Sustainability is now a sourcing criterion, but vague language can mislead buyers. A package can be recyclable in one market and difficult to recycle in another because collection, sorting and end-market conditions differ. A lighter structure may reduce material use but increase damage risk. A recycled-content claim may require separate documentation from resin, paper or board suppliers. The safest approach is to ask for evidence tied to the exact package and destination market.

The U.S. Environmental Protection Agency’s most recent municipal solid waste data are from 2018. In that dataset, containers and packaging accounted for 82.2 million tons of generation, or 28.1% of U.S. MSW generation. EPA also reported a 53.9% recycling rate for containers and packaging overall, while plastic containers and packaging had a 13.6% recycling rate and corrugated boxes had a 96.5% recycling rate. (epa.gov) See also: Food Packaging.

For companies selling into Europe, packaging rules are becoming more prescriptive. On December 16, 2024, the Council of the European Union announced formal adoption of the Packaging and Packaging Waste Regulation, including recycled-content targets for 2030 and 2040, packaging minimization requirements, labeling and information requirements, and restrictions on certain single-use plastic packaging. The Council release stated that the regulation would apply 18 months after entry into force. (consilium.europa.eu)

Practical sustainability questions for a supplier include:

• Can the supplier provide material declarations for the exact substrate and coating system?
• Does the design create problems for sorting, recycling or composting in the destination market?
• Are recycled-content claims supported by chain-of-custody or supplier documentation?
• Can the supplier explain trade-offs between downgauging, barrier performance, shelf life and damage rates?
• Are inks, adhesives, varnishes and laminates compatible with the intended recovery route?

Compare total landed cost, not only unit price

The lowest quoted unit price may become the most expensive option if it excludes tooling, plates, proofing, freight, import duties, storage, quality inspections or waste from production rejects. Buyers should normalize quotations before comparing them. A useful RFQ asks each supplier to price the same specification at several order quantities and to separate one-time costs from repeat-order costs.

Important commercial details include:

• Minimum order quantity and price breaks by volume.
• Tooling, plate, die, cylinder or mold ownership.
• Lead time for first order, repeat order and urgent replenishment.
• Payment terms, currency, validity period and material surcharge clauses.
• Packaging method for shipment, pallet pattern and warehouse requirements.
• Responsibility for artwork changes, barcode verification and regulatory text updates.
• Inspection rights, acceptance criteria and remedy for nonconforming goods.

For overseas sourcing, include logistics risk in the decision. Long transit times can erase the savings of a lower unit price if demand changes quickly. Domestic or regional suppliers may cost more per unit but provide shorter replenishment cycles, easier press checks and lower inventory exposure. Many buyers use a dual-supplier model for mature SKUs: one supplier for efficient volume and another for fast-turn projects, prototypes or emergency coverage.

A practical scorecard for shortlisting suppliers

A scorecard keeps the decision from becoming subjective. The weights below are not universal, but they reflect a balanced packaging sourcing process. A food-contact or pharmaceutical project should increase the compliance weight. A promotional display with a fixed event date should increase schedule and project-management weight.

Before final approval, ask two or three shortlisted companies to respond to the same technical brief. Compare not only their prices but also the questions they ask. A good packaging supplier will challenge unclear specifications, flag material risks and explain production constraints. A weak supplier may quote quickly but leave critical assumptions hidden until production begins.

Frequently asked questions

What is the difference between a printing company and a packaging company?

A printing company primarily focuses on putting graphics onto paper, film, board or other substrates. A packaging company may also engineer the structure, select materials, convert the package, apply finishing and manage performance requirements such as barrier, strength, sealing or packing-line compatibility. Many suppliers do both, but buyers should verify the exact scope.

Should I choose digital, flexographic or offset printing?

Choose based on run length, substrate, artwork variation, color expectations and finishing needs. Digital is often useful for short runs, fast changes and multiple SKUs. Flexographic printing is widely used for labels and flexible packaging. Offset remains common for high-quality folding cartons and some paperboard applications. The supplier should explain the cost and quality trade-off for your actual specification.

How many printing and packaging companies should be included in an RFQ?

For a new project, three to five qualified suppliers is usually enough to compare capability and cost without creating unnecessary evaluation work. More suppliers may be useful for commodity packaging, but complex or regulated projects benefit from a smaller group that has already passed technical and compliance screening.

What documents should I request before placing an order?

Request a formal quotation, material specification, proof approval record, quality plan, compliance declarations, certificate copies where relevant, production timeline, packaging and shipping method, and written terms for defects or delays. For food-contact or sustainability claims, ask for documentation tied to the actual materials used, not generic brochures.

When should I change suppliers?

Consider changing suppliers if defects repeat, documentation is incomplete, lead times become unreliable, technical questions are ignored, or the company can no longer support your compliance or sustainability requirements. For active SKUs, qualify the replacement supplier before ending the current relationship so that packaging supply does not interrupt sales.
