Private label frozen vegetables look like the easiest category in the freezer. The product is well understood, the processes are mature, and a dozen plants can make a competent bag of mixed vegetables. What actually goes wrong is almost never the vegetable. It is a net quantity declared in the wrong place, an artwork revision that reached the printer after the plate was made, a print minimum of 40,000 bags against a first order of 12,000, or a nutrition table calculated from a database instead of from the blend that was really packed. This guide is the sequence that avoids those, in the order the decisions have to be taken.
Stage 1: The brief, written as constraints rather than aspirations
A useful brief is three pages and answers six questions. Which SKUs, in which pack sizes. Which price architecture the range sits in, and therefore which quality tier. Which markets and languages. Which certification the customer’s own audit requires of the plant. Which launch date, counted backwards. And what the volume is per SKU per year, because that single number decides whether the rest of the project is feasible.
The most common defect at this stage is a brief that specifies the shelf appearance and leaves the tier unstated. “Premium look, entry price” is not a brief; it is a dispute scheduled for month four. Write the tier down in terms of measurable attributes: the calibre band, the maximum permitted proportion of defects, the drained weight where relevant, and the proportion of the highest-value component in a blend.
Stage 2: Product development and the golden sample
Two to four candidate formulations, produced on the real line rather than in a pilot kitchen, cooked and assessed by the way the consumer will use them. For a frozen vegetable that means from frozen: boiled, steamed, pan-fried, and in the case of a blend also microwaved, because water release and texture separate the candidates far more than raw appearance does.
At the end of this stage you keep a golden sample with a defined production date and a retained duplicate at the plant, plus a photographic reference of the accepted appearance. Sensory expectations that live only in an email will not survive a change of category manager.
Stage 3: The specification
The specification is written before the artwork, not after it, because several label fields are downstream of specification decisions. See the companion guide on writing a frozen vegetable specification for the seven blocks. For a private label programme, add four things.
The blend recipe with declared percentages and the tolerance on each component, since those percentages drive the ingredient list order and any quantitative ingredient declaration.
The nutrition basis: whether values are calculated from recognised composition tables or determined by analysis, and how often they are re-verified.
The allergen position for the product and for the line, including the basis for any precautionary statement.
The change control rule, which is the clause that will save the programme later: no change to recipe, component origin, packaging structure or process without written approval, and a defined notice period.
Stage 4: Packaging and the documents behind it
Packaging for frozen vegetables is a low-temperature performance question and a legal question at the same time.
On performance, the film must stay flexible and seal reliably at freezer temperature, survive filling and case packing without pinholes, and hold its print through condensation cycles. Typical retail formats are printed polyethylene or laminated structures in the 50 to 90 micron range depending on pack size and whether the bag is a pillow pack or a stand-up pouch; foodservice formats are usually plain or single-colour polyethylene liners of 40 to 60 microns inside a corrugated case. Those are ranges, and the variable that moves them is fill weight and handling severity, not preference.
On documentation, you must hold for every food contact material a declaration of compliance covering Regulation (EC) No 1935/2004 on materials and articles intended to come into contact with food, with the supporting migration information for the intended conditions of use. Frozen storage is a benign condition, but the intended use may include microwave heating in the bag, which is not benign, and the declaration must cover the use you print on the pack.
Two practical numbers govern the timeline. Print minimums for a rotogravure or flexo job are frequently in the tens of thousands of units per SKU per artwork version, and plate or cylinder costs are a one-off per version. Lead time from artwork approval to delivered film is commonly four to eight weeks, longer at seasonal peaks. Both are supplier-specific and both must be confirmed in writing before a launch date is promised.
Stage 5: The label, field by field
Regulation (EU) No 1169/2011 on the provision of food information to consumers sets the mandatory particulars. For a frozen vegetable pack the working checklist is as follows.
| Field | What it requires in practice |
|---|---|
| Name of the food | Legal or customary name, including the frozen state where its omission could mislead |
| Ingredient list | Descending order of weight at the time of manufacture; a single-ingredient vegetable may be exempt |
| QUID | Quantitative declaration of an ingredient emphasised in the name, in the labelling or in the image, which in a blend means the percentages of the named components |
| Allergens | Emphasised within the ingredient list where present |
| Net quantity | In legal units, in the field of vision with the name and, where applicable, the alcoholic strength |
| Date marking | “Best before” for frozen vegetables, plus the date of freezing where required for the relevant categories |
| Storage and use | Storage conditions including the freezer star rating or temperature, and conditions after opening where relevant |
| Instructions for use | Required where the food could not be used appropriately without them, which in practice covers cooking from frozen |
| Business operator | Name and address of the food business operator under whose name the food is marketed |
| Origin | Where required, or where its omission could mislead the consumer |
| Nutrition declaration | Mandatory declaration per 100 g, expressed in the prescribed order |
| Lot marking | Batch or lot identification, applied under the lot indication rules |
Three fields cause most of the reprints. QUID, because a photograph of the pack contents is an emphasis, and a blend that shows peas on the front generally has to declare the pea percentage. Instructions for use, because cooking instructions must reflect the process the plant actually validated, and a generic “boil for 4 to 6 minutes” that does not match the blanch level delivers an undercooked product. And the date of freezing, where the category rules require it, because it has to come off the production record and not off a template.
Language is a separate axis. A multi-country pack has to carry the mandatory particulars in a language easily understood in each market of sale, and the minimum x-height requirements for mandatory information mean that four languages consume real space on a 450 gram bag. Decide the country list before the artwork grid, not after.
Stage 6: Plant approval and audit
The customer’s own standard governs here. In practice a private label listing in the EU requires the plant to hold a GFSI-recognised certification, most commonly BRCGS Food Safety or IFS Food, and increasingly a social audit as well. Add to that any customer-specific requirements: a residue programme to a percentage of MRL as described in the MRL guide, a foreign body detection standard, a metal and optical sorting specification, and in some cases a second-party audit by the retailer’s own technologists.
Where the range includes an organic line, the certification chain has to be complete and current at every step, including the packer, and the certificate scope has to name the products. An organic claim supported by a certificate that does not list the product is a labelling non-compliance regardless of how the crop was grown.
Stage 7: First production and the pre-launch checks
Attend the first run, or have someone attend it. What you check is the boring set: the artwork on the reel against the approved proof, the code format and legibility, the net weight control record across the run, the seal integrity results, the metal detection challenge records, and a full pallet build to see how the cases behave.
Then hold a first-production sample against the golden sample and against the specification, cook both, and sign off on the comparison rather than on the intention.
What makes a SKU viable
The volume arithmetic decides more launches than the tasting does. A single SKU has to carry its own artwork version cost, its own print minimum, and its own share of line changeover time. In frozen vegetables, changeover between blends on the same line is short; changeover between pack formats is not.
| Cost element | Behaviour | Practical implication |
|---|---|---|
| Plate or cylinder set per artwork version | One-off, per version | Every language variant and every promotional pack is a new cost |
| Film print minimum | Step function, tens of thousands of units | First order below the minimum means paying for stock you store |
| Line changeover | Per run | Long tail of small SKUs erodes the range margin |
| Certification and audit | Annual, per site | Spread across the range, not the SKU |
| Analysis programme | Per season and per lot | Scales with the number of components and origins |
A realistic first order for a retail SKU is therefore anchored to the print minimum rather than to the forecast. Where the forecast is genuinely below the print minimum, the options are a plain film with a self-adhesive label for a first tranche, a shared base artwork with a variable panel, or a decision not to launch that SKU. All three are better than a launch that ties up cash in film.
Common mistakes
Approving artwork before the specification is signed, so a recipe change forces a reprint.
Calculating the nutrition table from a generic database rather than from the packed blend, then failing a retailer’s verification analysis.
Printing cooking instructions taken from a competitor pack rather than from the plant’s own cooked trials.
Forgetting that a front-of-pack image constitutes emphasis for QUID purposes.
Launching four language variants when two would have covered the markets, and paying four plate sets for it.
Omitting the change control clause, then discovering a component origin changed mid-season.
Treating the food contact declaration as a formality, when the pack is sold as microwaveable in-bag.
A worked example
A regional retailer launches a four-SKU frozen vegetable range: peas 450 g, cauliflower florets 450 g, a three-vegetable mix 450 g and a soup mix 750 g, in two languages, with a target launch 22 weeks out.
Weeks 1 to 3: brief and tier fixed, with the mix specified at 40 per cent peas, 30 per cent carrot dice and 30 per cent green bean cuts, tolerance plus or minus 5 percentage points on each, because that tolerance is what the artwork QUID has to be able to live with.
Weeks 3 to 7: three trial productions, cooked assessment from frozen by boiling and microwave, golden samples retained at plant and at retailer.
Weeks 6 to 9: specifications signed, including the residue plan, the allergen position and the change control clause. Nutrition determined by analysis on the trial production of each SKU rather than by calculation.
Weeks 8 to 12: artwork built against the signed specification, QUID percentages taken from the recipe, cooking instructions taken from the cooked trials, date marking format agreed with the plant’s coding capability.
Weeks 12 to 18: film printed against confirmed minimums; the soup mix, forecast at 9,000 units in year one against a 30,000 unit print minimum, is launched on a plain bag with a label for the first tranche and moved to printed film in year two.
Weeks 18 to 20: plant audit closed out, organic scope confirmed as not applicable to this range, first production attended.
Weeks 20 to 22: first-production versus golden sample sign-off, pallet build check, delivery into depot.
The range launches on time because the two decisions that usually break the timeline, the print minimum and the artwork-versus-specification order, were taken first rather than last.
FAQ
How long does a private label frozen vegetable launch realistically take?
Twenty to twenty-eight weeks from a signed brief to first delivery is a normal window for a new plant relationship, and twelve to sixteen weeks where the plant is already approved and only artwork and specification work is new. The binding constraints are usually plant approval and printed film lead time, not product development.
Who owns the artwork and the specification?
That is contractual and should be stated explicitly. Commonly the retailer owns the brand artwork and the finished-product specification, and the plant owns its process documentation. Ambiguity here becomes expensive when the range is moved to a second supplier.
Can one specification cover several suppliers?
Yes, and it should, provided the specification is written in method terms rather than in terms of one plant’s equipment. Where a clause can only be met by a specific machine, you have written a sole-source specification without meaning to.
What is a realistic minimum order quantity per SKU?
For retail packs the practical floor is set by printed film minimums, frequently in the tens of thousands of units per artwork version, which for a 450 gram bag translates to a first tranche measured in tens of tonnes. Foodservice formats on plain film have a much lower floor, often a single pallet layer per size, because there is no artwork constraint.
