FlowMarket
Where to find food packaging: FlowMarket is a B2B sourcing network powered by an AI agent. You describe the pack — product, shelf life, format, the machine it must run on, compliance documentation and recyclability requirements — and the agent matches you with suppliers of films, trays, closures and systems, then requests quotes, samples and lead times so you can compare them in one place.
Sourcing food packaging
Food packaging is bought by the square metre and judged by whether the product is still good on the last day of its shelf life. Those two views rarely meet in a quotation, which is why the cheapest film per square metre is so often the most expensive pack once waste, complaints and line speed are counted.
The enquiry that gets a useful answer describes the product and its life: what is being packed, how it is filled, what shelf life is claimed, what the distribution chain does to it, which machine runs the material and what the retailer or regulator expects on recyclability. That is enough for a supplier to propose a structure rather than quote a commodity.
Barrier is a specification, not a category
"High barrier" means nothing on its own. What matters is which barrier: oxygen, moisture, light, aroma or grease, and how much of each, because the mechanism that spoils your product decides which one you are paying for. Oxidation, moisture migration and microbiological growth all need different answers.
So state the spoilage mechanism and the target shelf life and ask for the transmission rates that support it, at the temperature and humidity of your actual supply chain rather than a laboratory default. A supplier who asks what limits the shelf life today is working the problem; one who leads with a material name is selling stock.
The pack has to run on your machine
Machinability is where theoretical savings go to die. Sealing temperature window, coefficient of friction, stiffness, web tension behaviour and how forgiving the material is of contamination in the seal all decide whether a pack runs at line speed or produces leakers at a rate nobody budgeted for.
Name the machine, its make and the format in the enquiry, and insist on trials on your own line rather than the supplier's. A material that costs three percent less and runs five percent slower is a loss, and a wider sealing window is worth paying for in any operation where the product itself sometimes ends up in the seal.
Compliance is documentation, and it is per material
- Framework conformity — food-contact materials are regulated across the EU, with specific rules for plastics; every material needs to comply.
- Declaration of compliance — the supplier's document stating conformity and the conditions of use it is valid for; ask for it before ordering.
- Migration testing — valid for defined food simulants, times and temperatures, so check the conditions match how your product is packed and heated.
- Inks, adhesives and coatings — part of the pack and part of the compliance question, especially with set-off and recycled content.
- Recycled content — permitted only through approved processes for food contact; ask exactly which, rather than accepting a percentage claim.
The practical point is that a declaration of compliance is valid for stated conditions of use. If you microwave, retort, freeze or fill hot, the declaration has to cover that, and a document written for ambient dry goods is not evidence for your application.
Recyclability is now a design constraint
European packaging rules are tightening towards recyclability requirements, recycled content targets and reduced packaging weight, and retailers are moving ahead of the regulation. This has pushed the industry towards mono-material structures that can actually be recycled, rather than multi-layer laminates that perform well and are recycled nowhere.
The honest tension is that mono-material usually means less barrier, so the question becomes how much shelf life you actually need rather than how much you have always claimed. Ask suppliers to show the trade-off explicitly: what shelf life a recyclable structure delivers for your product, and what it would cost in waste if you shortened the claim.
Cost sits in the pack, not the material
Compare packs, not prices per kilo or per thousand. A thinner film that needs a slower line, a tray that nests badly on a pallet, or a format that adds a secondary pack can each cost more than the material saves, and none of that appears in a price list.
Ask for cost per finished pack including line speed, giveaway, expected leaker rate, secondary packaging and transport efficiency, and ask what the minimum order quantity and lead time look like for a print change. For most food producers, packaging obsolescence from artwork changes quietly costs more than the material specification ever will.
How the AI agent matches suppliers
The agent reads your requirement rather than your keywords. It searches the FlowMarket network and connected industrial directories together, scores every candidate on how well it answers what you described — product and shelf life requirement, barrier properties, format and machine compatibility, compliance documentation, recyclability and recycled content, volumes and region — and drops anything that does not clear the bar. Each match comes back with a plain-language reason, so a film converter, a tray manufacturer and a packaging distributor never look the same.
