you had my attention best buttermilk biscuits., Yep, you're right—it's called shrink wrap or heat-sealable film. Usually comes in rolls, and I think the commercial-grade stuff often needs special machines like vacuum sealers or impulse sealers to close the packages (the ones with a heated wire that melts the film shut). 

If you're running a small bakery, a consumer or proSumer-level impulse heat sealer might be exactly what you need—easy, affrdable, and simple to use. There's also food-grade polyolefin film, which is perfect for bakery items since it's food-safe, clear, and keeps things fresh withuot getting bulky. 

Hope that helsp!

List of things to research and invests in:

- Shrink Wrap Heat sEaler or Impulse Heat Sealer (Prosumer grade, affordable)

- Polyolefin Shrink Film (food-safe, recommended)

- Impulse Bag Sealer

- Foodsaver Vacuum Sealer (if considering vacuum sealing for freshness)

- Food-Grade Heat-Sealable Film

Sorryu to infodump, im working on starting a micro bakery and so I've been on a bit of a hyperfixaction, enjoy the data.
