The quick answer: 2026 bands

Machine class2026 band (ex-China)What decides the price
Plastic bag making machineUSD 8,000–40,000+Automation (servo vs mechanical), width, sealing type (bottom/side), printing integration
Paper bag machineComparable classBag format (SOS, flat), handles, print units
PVC pipe / profile extrusion lineUSD 20,000–200,000+Single vs twin screw, die and calibration, cooling train, haul-off — and continuous-duty build quality
PET preform productionInjection machine USD 30,000–75,000 + mould setCavity count rules everything: a high-cavitation preform mould can cost as much as the machine under it

The film question behind every bag machine

A bag machine converts film — it doesn't make it. If you're buying film, your margin lives on your film supplier's price list; if you're extruding your own, add a film blowing line to the project and the working capital for resin. The honest project question is "bags from bought film" versus "extrusion plus conversion" — different capital classes, different businesses, and we'll price both before you choose.

Pipe: the extrusion line is a system, not a machine

The extruder is a third of a pipe line: die and calibration tooling per diameter range, the vacuum and cooling train, haul-off, cutter and belling. Quotes that look cheap are usually quoting the extruder alone — the same partial-system trap we flag on gypsum "plants". And pressure-pipe markets buy certification: budget the testing regime with the line.

Preforms: cavity count rules everything

Preform economics are mould economics. The machine is the workhorse-band injection machine; the money decision is cavities (16? 32? 48?), hot-runner quality and cycle time — which set your preforms-per-hour and your cost per unit. Most bottlers should also price the alternative honestly: buying preforms from established converters, which keeps capital in the filling hall where the brand lives.
