How a brand's packaging buyer chooses a new supplier

A brand starts looking for a new carton supplier when the current converter missed a festive dispatch, drifted on the shade of a reprint, or raised the price twice. So the packaging buyer judges a new converter on samples, on print against the approved master, and on the capacity to run the volume. Then comes the question that settles it, though nobody asks it aloud. If board prices jump or festive orders arrive early, will you still deliver? Answer that on paper and you are let in, first as the second supplier.

Who at the brand is choosing

Four desks look at a new converter, and any one of them can stop it.

Packaging development owns the specification and the artwork, and sits in R&D or marketing depending on the brand. It decides whether your sample is close enough to the approved master. Marketing judges the shelf look, and notices a shade drift that an instrument reading calls acceptable. Quality runs the line trial. Then it inspects every lot you deliver, for as long as you supply. Purchase compares price, minimum order, payment terms and lead time.

A converter who knows only the purchase manager is selling a price. You need a name at each desk. Qualified business introductions reach the development and quality people who rarely answer a cold call. More for converters: packaging manufacturing sales and marketing.

What the samples are tested against

The buyer has seen beautiful samples before and assumes the owner picked them by hand on a good day. What the buyer tests is whether production will match them.

Print is checked against the approved master in the brand's light booth, not under your shop lights. Where the brand packs by machine, cartons go through its cartoning line at full speed. A millimetre matters. A carton that is slightly off, or a crease that cracks, jams an automatic line and fails the trial. Board is checked for GSM and caliper against the specification, and the varnish for rub. Then the buyer asks for a sample from a real production run, or comes to watch one. Our note on sampling packaging covers what to send at the first request and what to charge for it. Food brands add a list of their own, set out in what food packaging buyers ask for.

The question nobody asks aloud: can you keep supplying?

A buyer who has been let down once by a converter with good samples will ask about continuity. So prepare a one-page continuity sheet and hand it over before purchase asks. Put on it:

• Machines by process (printing, die-cutting, folding and gluing), with the sheet size each runs
• A second machine or a partner unit for each critical step, or an honest "none"
• Board and ink sources, and how much board you will hold ahead of the festive peak
• How you will price when paper moves: a price tied to a stated board rate, with notice before any change
• Power backup, and what happens when the press breaks down mid-order
• Your present customers by type, and the share of your capacity this brand's volume would take
• The person the buyer rings when a dispatch slips, with a mobile number

The pricing line matters more than converters expect. A fixed price you break after three months is worse than a clear rule the buyer can explain to their own finance team.

How a new supplier gets in

A brand that has run with one converter for years will not move everything to a stranger. Expect to start with one or two SKUs and a trial order, with the incumbent still supplying the rest. Ask purchase at the start what they will review before moving more share to you, and when.

Accept the second-supplier role. Brands keep a second source as insurance, and a second source that performs through a festive season becomes the first call when the incumbent slips. Do not undercut so hard to get in that the next reorder needs a price rise. Purchase keeps your entry price on file.

Imagine a carton maker in Bhiwadi

Imagine a carton converter in Bhiwadi bidding for a Delhi stationery brand that sells crayons and colour pencils through school-supply dealers. The details are illustrative. The owner sent carton samples printed on the best board and approved them without a second opinion. The brand placed a trial order for two pack sizes ahead of the school reopening season. On the reprint the brand's yellow drifted from the master, and dealers complained that new stock looked different beside the old on their shelves. The converter reprinted one pack size at its own cost. When purchase asked how much board it would hold for the next school season, the owner had no answer.

The owner went back with three things. First, a request for the approved master and a signed shade standard with its limits marked, and a habit of checking each run press-side under a light booth. Second, a continuity sheet with a board stock plan for the months before schools reopen and a named partner unit for die-cutting overflow. Third, a question to purchase about what would be reviewed after the season, written down. The brand kept both packs with this converter through the season and agreed to discuss a third at that review.

When a brand is not worth chasing

If one brand's volume would fill most of your capacity, winning it makes you dependent on it. Cap what you offer, or take the risk with your eyes open.

Some buyers want only a price to beat their present converter down. The signs are an enquiry with no artwork, no offer of a line trial and no quality contact named. Send a quotation for the stated specification and spend your time elsewhere. And if the brand needs a process you do not own, such as gravure for long runs, say so instead of quietly subcontracting it.

Write the continuity sheet before a brand asks

Write your continuity sheet before the next brand asks, while there is time to fix what it shows. Any line that says "none" is the first thing a buyer will find. If you want help reaching the right desks at the brands you want to supply, tell us what you need.
