What are the Types of Cleanroom Wipe Border/Edge Seals?
- Sealed Border
- Sealed Edge
- Laser Sealed Edge
Cleanroom Wipers have sealed edges to prevent particle and fiber generation and provide a clean wipe. Cleanroom wipes can have a sealed border, a sealed edge, or a cut edge. The level of fiber and particle release will depend on your wipe seal. Note the difference in sealing the border around the wipe (most clean) or just the wipe edge (most common).
Cleanroom Class 1-10 (ISO 3-4): Sealed Border
Sealed Border wipers are the cleanest & best performing choice for your most critical tasks. Maximum cleanliness and fiber control.
A proprietary process using pressure & heat is used to create a border seal for optimum fiber and particle retention, resulting in a 5mm Ultrasonic Border Seal around the border of the wipe. The most rigorous washing and border sealing process for applications requiring maximum particle and fiber retention.
Cleanroom Class 10-100 (ISO 4-5): Sealed Edge
Sealed Edge wipers are exceptionally clean and a common critical task wiper. The difference over border seals is that only the edging of the wipe is sealed instead of a border around the edge of the wipe. A Laser Sealed Edge is provided on all sides for maximum fiber and particle retention. A Ultrasonic Sealed Edge involves a process using pressure & heat to create an ultrasonic seal for fiber and particle retention. Ultrasonic Sealing is superior to Laser Sealing as it results in a softer edge, and lower carbon levels. Soft sealed edges retain all fiber in scratch sensitive applications.
