Pouches and bags
We supply foil chevron pouches in a PA/Alu/PE laminate. The foil gives a near-total barrier to oxygen, moisture, and light, for sensitive devices, diagnostics, and reagents that need a long shelf life. Foil is not gas-permeable, so these pouches are typically radiation-sterilized. For EtO, we supply foil header bags with a porous vent. Sourced from qualified manufacturers in North America and Europe.

What it's for
Some products degrade when exposed to air, humidity, or light. A foil pouch blocks all three, which protects sensitive devices, diagnostics, and reagents over a long shelf life.
The laminate has three layers. PA (nylon) adds toughness and puncture resistance, aluminum foil is the barrier, and PE is the sealing layer on the inside.
Foil does not breathe, so EtO gas cannot get in through the pouch wall. Foil pouches are typically sterilized with gamma or e-beam. If your process is EtO, you need a foil package with a built-in porous vent, such as a porous header or breather patch, that lets gas in and out. It is sealed off below the vent after sterilization to restore the full foil barrier.

Compatibility depends on grade, coating, and your process. Validate in your own sterilization cycle.
Ordering
Share the format, size, weight or film, and how you seal and sterilize. If the material is already validated, send the spec or part number and we'll quote exactly that, or tell you plainly that we can't.
We source samples from qualified manufacturers and quote per project.
Order it alongside your die-cut lids and cards. We receive and check it in Kensington and ship it with your other parts, and CleanCut handles any delivery or quality issue.
FAQ
Choose a foil pouch when the contents must be protected from oxygen, moisture or light. The PA/Alu/PE laminate gives a near-total barrier. Typical applications include sensitive devices, diagnostics and reagents with long shelf-life needs.
PA/Alu/PE laminate layers:
Foil pouches are typically radiation sterilized, and they are compatible with gamma and e-beam. They are not gas-permeable, so they are not recommended for EtO unless the foil package has a built-in porous vent that is sealed off after sterilization. For EtO, ask us for a vented foil header bag with a Tyvek® vent. The PE sealant makes steam unsuitable, so steam is not recommended. Validate in your own sterilization cycle.
Yes. Custom sizes, printing and seal options are available, quoted per project. Foil chevron pouches are sourced from qualified manufacturers in North America and Europe and supplied by CleanCut. We confirm each manufacturer's certification (standard, registrar and expiry) in writing as part of your supplier qualification. Each lot ships with our certificate of conformance, which records the manufacturer's lot number.
Request samples on the quote form. Give us the inside dimensions, what the contents need protection from, and your sterilization method. We will come back with questions and a sample plan.
