What gets approved, and in what order
A private label pack is not signed off once. Three separate things are approved, and each one can fail on its own: the product construction, the pack structure (bag, box or carton), and the printed artwork. A brand that treats them as a single approval usually finds the gap at the pre-production sample, when the film is already printed. The sequence that keeps the three apart is product sample first, pack mock-up second with no print, printed pack third. Only the third one is expensive to change.
Keeping them apart also tells you what went wrong. A product sample fails on absorbency, fit or thickness. A pack mock-up fails on fill, seal or shelf fit. A printed pack fails on colour, barcode or legal panel. Approve all three in one meeting and you cannot tell which one you are looking at when something is off.
Claims: what has to exist before it can be printed
On-pack copy splits into four kinds, and only some of them need a test record behind them. Treating them the same is how packs end up either over-claiming or too vague to sell. This article covers the disposable format throughout; the range behind it is on the disposable menstrual pants page.
Performance claims — absorbency in millilitres, "up to X hours", "holds X rinses". These need a named test method and the record behind the number. Ask which method was used and who ran it: an in-house bench comparison is not the same evidence as a test against a published standard. A number without a method is marketing copy, and it is the first thing a retailer's technical team asks about. The guide to absorbency and rewet testing lists what to request and what the results mean.
Material claims — "breathable backsheet", "cotton-like top sheet", "chlorine-free pulp". These should trace to a material specification rather than to an impression of the product. Breathability is the usual offender: air permeability and moisture vapour transmission are separate measurements, and a film can score well on one and poorly on the other. How breathability is built into period pants sets out which measurement answers which wording, and the materials and construction guide covers the rest of the build.
Sensory claims — soft, quiet, thin, discreet. These are fair to print if the sample supports them, because they describe what a buyer can feel. They carry no test requirement but they do carry a consistency requirement: bulk has to feel like the approved sample. That makes the sealed golden sample more important than the wording.
Regulated and safety claims — "hypoallergenic", "dermatologically tested", "antibacterial", "medical grade". Be strict with these. Each implies a specific test or a regulatory status in the destination market, and printing one without the underlying report is a compliance exposure the factory will not carry for you. If a supplier offers the wording and cannot produce the report, take the wording off the pack.
Environmental wording needs its own caution. "Biodegradable" and "compostable" are defined by standards rather than by intent. A pack that prints either without a standard reference and a certificate behind it is a claim you cannot defend in the market that matters most to you.
Descriptors that look like claims but are not
Day, night, super, ultra, maxi, travel. These are positioning words rather than measured performance, and they are usually safe to print because no buyer reads them as a number. The trap is letting a positioning word drift into a performance statement. "Night" is a use case; "twelve hours" is a claim. Combine the two in one line and the line inherits the evidence requirement of the claim. Keep positioning words in the headline and numbers in the specification panel, where each number can be sourced from a record.
Sampling rounds: what each one is for
Most private label programmes run three rounds, and each answers a different question. Round one is a construction sample from stock tooling: it answers whether the product is the right build at all. Round two is a pack mock-up with no print: it answers whether the product fits, seals and presents correctly, and whether the pack count is right for the shelf or the e-commerce image. Round three is the printed pack: it answers colour, barcode and legal panel.
Ask the supplier how many rounds the quotation includes and what a further round costs. Rounds are usually the cheapest line in the whole project and the one most often left out of a comparison, because a quotation that includes no revision rounds is not cheaper, it is a quotation that expects you to accept the first output. Do not approve a printed pack before the product is approved: that is how brands end up holding packaging for a product they cannot sell.
Packaging: the four decisions that set the cost
Packaging cost is not one number. It is four decisions taken in order, and each one locks the next. Format — printed poly bag, individual wrap plus outer bag, rigid box, stand-up pouch — sets the material and the seal. Print colour count sets the plate cost. Pack count per unit sets the carton maths and the shelf price point. Language versions set how many separate print runs you are buying.
These four multiply rather than add, which is why three pack versions cost more than three times one. The private label period pants guide compares the formats; the point to carry into a quotation is the multiplication, because it is where the cheapest available saving sits. Cut a version and you cut a plate set, a film minimum and a proof at once. Squeeze the per-piece price and you cut nothing structural.
Ask for the pack cost broken out from the product cost. A single landed price hides which of the four decisions is driving it, and that is the decision you can still change before plates are cut.
Artwork proof: check the film, not the file
The artwork proof is the last cheap moment in the project. Five checks belong on the printed film rather than on the PDF.
Barcode — scan the printed film at the magnification it will actually be printed at, with the quiet zone the retailer requires. A digital file that scans proves nothing about registration or ink spread.
Colour — approve from a physical proof, under the light the pack will be judged in. Screen approval is a guess with a signature on it.
Legal panel — confirm the panel has room for the market's required statements before the layout is frozen, not after. Space is the item most often missing, and it is the item that forces a full reprint.
Language versions — get in writing which versions share a print run. A shared run is cheaper and it also means that a text change hits all of them at once.
Plates — confirm who owns the plates, where they are stored, and whether storage is charged for reorders. This one sentence decides your reorder cost and your ability to move the pack to another supplier later.
Change control: what triggers a re-approval
Once the printed pack is approved, four kinds of change send you back through the gate: any artwork edit, any pack dimension change, any change to the film or board, and any change to the absorbency grade. The first three are obvious. The fourth is the one buyers miss, because the absorbency grade is fixed before the film is cut — the claimed performance is printed on it. Change the grade afterwards and the artwork, the film and the claim all have to be redone together.
Put a revision number on the specification and repeat it on the artwork approval sheet. Then a change becomes a new revision instead of a conversation about which version is current.
Who signs each gate
A private label approval is rarely one person's decision, and the delays come from not knowing who owns which gate. Product sign-off usually sits with whoever owns the range commercially. Pack structure sign-off sits with the person who owns the channel, because fill, shelf fit and carton maths are retail constraints rather than product ones. Claim and labelling sign-off should sit with whoever accepts the compliance exposure, and that is normally not the buyer.
Name the three owners before sampling starts. When a gate has no named owner, it gets approved by whoever is in the meeting, which is how a supplier ends up printing text nobody internally agreed to.
What to keep for the reorder
A reorder is only as good as the paperwork from the first run. Keep four items: one sealed product sample per size, one signed printed pack, the approved artwork file with its revision number, and a written note of plate ownership and storage terms. With those four, a reorder is a purchase order. Without them it is a new project that begins by re-approving what you already approved once.
What to put in the RFQ
Six questions cover packaging, claims and approval scope in a single message: which pack formats the quotation assumes and what each costs separately from the product; how many artwork revision rounds are included and what a further round costs; which test reports exist for the claims you plan to print, with the method names; which materials or components change between sample and bulk; how the minimum differs between a stock pack, a custom printed pack and a custom structure; and who holds the plates.
Send the same six questions to every supplier and ask for the answers in the same order. Quotations that answer a different set of questions cannot be compared on price. A quotation request that states what to include is the cheapest way to make them answerable, and if the core itself has to change rather than the pack, that is an OEM project rather than private label and it needs its own sampling plan. For the minimum behind each answer see the menstrual pants MOQ guide; for how the pack is checked before it ships see quality control for sanitary pants. If you are still mapping the range the pack has to cover, start from the product range by format and the sourcing guides hub.
