18" x 45" Adhesive Tacky / Sticky Mats (120 Sheets)

These 18" x 45" adhesive tacky mats are multi-layer entrance control mats designed to remove dirt and other particulate from foot traffic and cart wheels as people and material move into cleanrooms, labs, and other controlled areas. The peel-off, numbered sheets make layer changes fast and visible, helping teams maintain a consistently “fresh” contact surface where outside particulate most commonly enters the process.

Note: Specifications shown are taken from the published SOSCleanroom listing. If a program requires additional material, adhesive, or cleanliness documentation, request supporting data through your quality and procurement process.

• Numbered corner tabs help teams track remaining sheets at a glance.
• Smooth, effective adhesive surface is designed to stand up to shoes, booties, and cart wheels without routine surface damage.
• Peel-off sheets eliminate messy cleaning and simplify maintenance of a consistently tacky contact layer.
• A bright surface makes it easier to see when the top layer is loaded and should be changed.

1. Peel off the protective film on the back side of the mat (opposite side that the numbers face) to expose the adhesive backing.
2. Place the mat on a clean, dry surface in the desired location.
3. Peel off the top layer of protective film to expose the first usable sheet (number 30).

• Place for behavior control: Install where traffic naturally “commits” to entry (door thresholds, airlocks, gowning exits), not where carts can bypass the mat.
• Define change criteria: Change layers based on a visual loading trigger and a maximum time/traffic rule. Overloaded sheets lose effectiveness and can re-transfer particulate.
• Foot-and-wheel discipline: Encourage a full contact step pattern and ensure cart wheels roll fully across the mat (avoid half contact that defeats the control).
• Transfer-object prevention: Treat unused mats and opened cases as controlled items (bagging discipline, defined storage location, controlled introduction to the classified area).
• Not a substitute for cleaning: Mats help reduce incoming particulate at the boundary, but they do not replace validated cleaning/disinfection of floors and traffic routes per your site program.

• Sheet edge lift/curl: Often caused by poor adhesion to dusty or damp floors. Prevent by cleaning and fully drying the placement area before install.
• Under-changing: A visibly loaded sheet becomes a re-distribution surface. Prevent with a defined change trigger and logged checks at shift start/end.
• Bypass traffic: Carts or personnel detour around the mat. Prevent by placing mats where workflow forces contact and by training on why the control exists.
• Poor transfer handling: Unbagged mats moved from uncontrolled storage to clean areas can import contamination. Prevent with zone-based storage and defined transfer packaging.
