A producer hands over a batch and gets back sealed, coded packs. The packs look right. Nobody weighs what went in against what came out, so the producer accepts the figure given and moves on. Wastage is the one cost in packing that nobody sees leaving, and near-zero wastage filling is the discipline of making it visible.

It leaves in small amounts. A little extra in every pouch. A film of powder on the hopper wall. A run of packs thrown out at the start because the weights had not settled. Each loss is too small to argue about, which is why none gets argued about.

Wastage is product that does not end up, correctly weighed, in a sealed pack that can be sold. It leaves a filling run through five doors. Overfill gives away a little extra in every pack. Spillage and dust scatter powder and granules onto surfaces and floors. Residue stays on hoppers, in nozzles and along the walls of the machine. Rejected packs, with a wrong weight or a faulty seal, are discarded. Changeover loss takes product when a machine is set up or cleaned between runs.

Near-zero wastage means all five are controlled and measured. It does not mean zero, and any packer who promises zero is describing a machine that does not exist. Some product always stays in the equipment. Some packs always fail a check. The honest claim is that the remainder is small, known and accounted for.

This matters because of the producer’s margin. Raw material and recipe are the largest investment in the product, and every unit lost in filling comes straight out of that. On a small run the loss is easy to wave away. Across a season it is not. A figure that cannot be checked is not a promise. It is a phrase, and measurement is what separates the two.

Near-zero wastage filling is a figure, not a phrase

Every claim about wastage reduces to one test: quantity in against quantity out. The producer sends a known weight of product. It comes back as sealed packs of a stated weight, plus rejects, plus residue left in the equipment. Add those three and the total should match what was sent, within a small and explained difference. When it does, the packer is measuring. When the packer offers a percentage with no record behind it, the packer is advertising.

The test works for every product type, but the losses differ. Fine powders lose to dust. Thick pastes lose to residue in hoppers and nozzles. Thin liquids lose to drips. A packer who has filled your kind of product can say in advance where yours will lose, and should.

Five questions show what a packer actually measures

Ask how the product is weighed before filling and the finished packs after, and whether the difference can be shown. Ask how pack weights are checked during the run, not only at the start. Ask what happens to the product left in the machine when the run ends. Ask what is done with packs that fail a check. Ask whether the loss on your run will be stated in plain numbers.

A packer who answers each with a method and a figure from a real run is measuring. A packer who answers with a promise is not. The difference is audible within the first minute of the conversation.

Producers ask about price before anything else, and wastage almost never comes up. It comes up after the first run, when a producer who sent in a known quantity does the arithmetic at home and the packs do not add up. The conversation that follows is the most uncomfortable one in packing, because nobody kept records and nobody can say where the difference went.

Sunil V. Dorkar’s observation from these conversations is that producers who ask about loss on day one rarely have a problem later. The question itself sets the terms. A packer who knows the producer will reconcile the run keeps the run honest.

It works in the other direction as well. A thick pickle loses more at changeover than a dry powder, and a packer who says so is more trustworthy than one who gives every product the same promise. The founding rule of the business applies directly: it is better to say a product will lose more than expected, or to say I do not know until the first run is measured, than to promise a number and be wrong.

Shree Nanda Industries fills powder, granule, liquid and paste products by machine and treats quantity in against quantity out as the test of every run. The questions above are meant to be put to us as readily as to any other packer, and products that lose more than others are named as such before the run. For how a product moves from a producer’s kitchen to a sealed, coded pack, read contract filling and packaging, and for the point where manual filling is still the better choice, machine filling vs manual filling.

A promise about wastage is only as good as the sheet behind it. The producer who learns to ask for that sheet, once, with the first packer, carries the habit into every supplier after. Sealing, coding and carton packing all leak margin in their own quiet ways, and each answers to the same question: what went in, and what came out. The habit costs nothing to learn and pays back on every batch that follows.
