Cleanroom (Tacky) Mats are made of thin layers of adhesive coated polyethylene film. These sticky layers remove particulates from shoes and cart wheels with each entry to the cleanroom. The Mats are designed to resist adhesive transfer, preventing sheet to sheet delamination, prevent distortion and slippage and the adhesive backing secures the mat to the floor. Each mat has thirty numbered, removable sheets (unless noted otherwise) for quick and easy maintenance. No frame is required, full width backing adhere the mat in place on the floor.
