Food packaging buyers: what documents and assurances they ask for

Your sample and your rate went down well with the snack brand's purchase manager. Then their quality executive emails a two-page list, and you can answer three lines of it. Food packaging buyers want proof of three things: the material suits the food it will touch, every batch matches the one they approved, and your plant handles their packs cleanly. Ask for that list in writing. Sort each line into what you hold, what your raw material supplier can give you and what you cannot give, then reply in their order. Never answer a document request with a promise.

Who is asking, and what they are protecting

Purchase wants price, delivery and credit. The quality executive approves suppliers, and if a customer complaint is traced back to the pack, the investigation carries their name. So their questions feel slow and suspicious. They are meant to.

Behind them there may be another buyer. A supermarket chain, a quick-commerce platform or an export customer hands the brand its own supplier questionnaire, and the brand passes the packaging pages to you. Ask whose requirement each line is. A chain's requirement is fixed for the brand. A quality executive's own preference can sometimes be met another way.

Which declarations and tests apply depends on the food, the material and the buyer. The rules differ by body and change. Check with your own adviser or the regulator before you claim a pack meets any of them, and let the buyer's quality team say what they need.

Ask for the list, then answer it line by line

Do not send a forty-page folder unasked. A quality executive who has to hunt for the one paper they need assumes it is missing. Ask this instead:

Could you send the list of documents your quality team needs from a packaging supplier, and the name of the person who approves suppliers? We will reply against each item.

Then answer using their numbering. Mark each line as attached, as requested from your supplier with the date you asked, or as not held. For a line you do not hold, say what you can arrange, such as a test at a laboratory the buyer names, at a cost agreed before the sample goes.

The papers, grouped the way a quality team reads them

Keep your folder in these four groups, holding only papers you can stand behind.

About the material

• A specification sheet for each pack: board grade and GSM for a carton, the layer structure for a laminate, dimensions with tolerances.
• Declarations of suitability for food contact from your raw material suppliers, naming the grade. Ask the board mill, the film maker, the ink maker and the adhesive maker. Each issues its own.
• Laboratory reports for the tests the buyer names, run for their food and their conditions. A report done for dry snacks says nothing about oil, frozen storage or hot filling.

About each batch

• An inspection report with every lot: dimensions, GSM or thickness, print check, and seal strength for pouches.
• Batch codes on every bundle or roll, traceable to the raw material lots used.
• Retained samples from each lot, stored where you can find them in five minutes.

About your plant

• Pest control records, and a trap plan.
• Written rules on glass, brittle plastic, jewellery and eating in production areas.
• Cleaning records for the machines that run food packs.
• Any food safety or hygiene certification you hold, with its scope exactly as printed.

About change

• An undertaking, in writing, to tell the buyer before you change a raw material, ink, adhesive or supplier.
• Your complaint procedure: who they call, how a suspect lot is held, how you trace it back.

Words to keep out of the quotation

Some phrases make a quality executive stop reading. "Food grade" with nothing behind it. "100% safe". "Approved" by a body that has never seen your plant. "Non-toxic inks" without the ink maker's declaration. Each one tells them you do not know what you are being asked.

Write what you have instead: the board, its mill and grade, with the mill's declaration attached. Read the buyer's supplier agreement before you sign it, too. Some ask the packaging supplier to carry recall costs or broad indemnities for the food itself. Those clauses need your lawyer, not your sales team.

Imagine: a carton maker in Hubballi and a Dharwad sweets brand

Imagine a carton maker in Hubballi that prints boxes for a Dharwad pedha maker. The details are illustrative. The pedha maker wins a listing with a supermarket chain in Bengaluru, and the chain's quality team sends its supplier questionnaire. The packaging pages land on the carton maker's desk.

The owner replies with a letter on the company letterhead: "Our cartons are food grade and fully safe." It comes back the next day. The chain wants the board mill's declaration, a named test from a laboratory it accepts, and an answer on where the butter paper liner comes from.

So the owner starts again. The board mill and the butter paper supplier are asked for their declarations. The chain's quality team is asked which test they want and which laboratories they accept, and the pedha maker is told the test cost before it is booked. Every bundle now carries a batch code, and a sample from each lot sits on a labelled shelf. The second reply follows the chain's numbering line by line, with two items marked "requested" and the date they were asked for. The first reply had cost a week of the listing schedule. Approval came on the second submission, with the laboratory report still to follow.

When the list asks for more than your plant can carry

Some buyers need a third-party certification or audit you do not have. Say so, and say whether you plan to get it. A supplier who admits a gap keeps the conversation going. A supplier caught bluffing has a hard time getting it back.

Some foods and export markets carry stricter rules. If your plant prints food cartons and chemical labels on the same line, expect the question and have the answer ready. Where a segment needs controls your plant is not built for, decline it.

Build the folder before the next list arrives

Set up the four groups on a shared drive. Ask your suppliers for their declarations now, and start batch-coding bundles before anyone asks. If you also want a plant presentation for visiting quality teams, that is a capability presentation. The rest of the converter's selling job is on the packaging manufacturing page. To get the folder and the presentation built around your own plant, tell us what you need.
