Cleanroom Sticky Mats are floor mats designed to remove dirt and dust from cart and foot traffic upon entering a controlled environment. They contain 30 sheets of polyethylene with a sticky surface. Once the top layer is contaminated and no longer tacky, the sheet is peeled away to reveal the next clean sheet. The mat is attached to the floor with an adhesive backing to eliminate movement once the mat is positioned. Each mat contains 30 individually numbered sheets that easily peel off, revealing an new clean layer.
