Cleanroom Wipes

What are the Types of Cleanroom Wipe Border/Edge Seals?

1. Sealed Border
2. Sealed Edge
3. 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. 

Cleanroom Class 100-10,000 (ISO 5-7): Hot Knife or Laser Sealed Edge

Are All Cleanroom Wipes Lint-Free?

Controlled environments need to regulate the amount of fibrous materials that can potentially cause harm to sensitive machinery and lab testing. Standard operating procedures include precautions to prevent damage. The most obvious solution to prevent lint fibers damaging components is to only use lint free cleanroom wipes. There are many different grades of cleanroom wipes, depending on the ISO class of your cleanroom. Ensure you use a compatible lint free wipe material that corresponds with your ISO class. The difference between a regular wipe and ISO cleanroom wipe is the amount of lint material that sheds in use, the quality and regulation of the manufacturing facility, and the varying types of border edge seals.

Cleanroom wipes are designed for a variety of uses. Polyester lint free wipes are one common material for wipes because they are soft and non-abrasive. The fast-drying dense-weave increases absorption without shedding lint. Synthetic fibers resist wear and tear and keep your cleanroom lint free.
