Cleanroom paper, a specialized product built on a Bond substrate, is designed to play a crucial role in preventing particle and contaminant release. It’s not just any paper- it’s a high-quality, durable writing paper weighing over 50 g/m2, similar to bank paper, that was originally crafted for documents such as government bonds. It’s worth noting that bond paper, often mistaken for basic photocopier paper, is heavier and fortified with 25% to 100% cotton fiber for added strength. The final step involves a specialized process using low-particulate and latex-coated fiber, ensuring the prevention of particle and contaminant release.

Characteristics of cleanroom bond paper

The following are the leading characteristics of cleanroom bond sheets.

The most common weights are 68 g/m2, 85 g/m2, and 104 g/m2.
It is likely made of mostly cotton fiber, which has undergone specialized processing using low-particulate and latex-coated fiber to prevent particle release.
Contains very little to no wood pulp.
Rigorously tested to ensure it is free from contaminants, making it a safe and reliable choice for use in sterile environments.
