Polyethylene film is a common web for bags, pouches, and liners. It is tough and flexible, and it heat-seals to itself, so pouch-making and form-fill-seal lines can form and close packages straight from the roll.
Solid film does not let sterilant gas through. Gamma and e-beam pass through the package, so the film works well with both. For EtO, pair it with a porous component such as Tyvek® or medical paper, and validate the cycle.
The manufacturer makes the film in an ISO 14644-1 Class 8 cleanroom, which helps keep particulate off the web before it reaches your line.
Typical applications include
- Pouch and bag making
- Form-fill-seal webs
- Liners
- Radiation-sterilized packages
