What it's for
Rollstock is material on a roll for your own equipment. Lidding lines cut and seal it onto rigid trays or blisters. Pouch-making and form-fill-seal lines combine it with film to form pouches.
The heat-seal coating is what bonds Tyvek® to the tray, blister, or film. It is applied in a pattern, not a solid layer, so the web stays breathable for sterilization. When the package is opened, the seal gives a clean, visible peel.
Choose Tyvek® 1073B for strength and puncture resistance. Choose 2FS when the device is lighter: it is a lighter web suited to high-speed form-fill-seal, and it keeps material cost down.

FAQ
Choose Tyvek® 1073B for strength and puncture resistance, for example with heavy or sharp devices. Choose 2FS for lighter devices and high-speed form-fill-seal lines. It is lighter and costs less. If you are unsure, tell us about the device and your line.
Coated Tyvek® rollstock basis weights (these include the heat-seal coating):
Custom widths and roll sizes are available. Give us your web width, core size, and roll length or diameter on the quote form.
A pattern coating covers only part of the surface. The uncoated areas keep the Tyvek® web breathable, so sterilant gas can still pass through. The coating also gives a clean, visible peel, so the opened seal is easy to inspect.
Coated Tyvek® rollstock is compatible with EtO, gamma and e-beam. Tyvek® is limited to restricted, lower-temperature steam cycles, up to 127 °C, so ask us before you plan one. Compatibility depends on grade, coating, and your process. Validate in your own sterilization cycle.
