Purus International PS 2645 38 W EnviroTack Adhesive Mat, 26x45, 30-Layer, White, Case of 4
Purus International PS 2645 38 W EnviroTack Adhesive Mat, 26x45, 30-Layer, White, Case of 4
The Purus EnviroTack PS 2645 38 W is a 26" x 45" white cleanroom sticky mat with 30 peel-away adhesive layers designed to capture and contain dirt, dust, and particulate from foot traffic and wheeled equipment at controlled environment entryways. The 26x45 size bridges the gap between standard 24-inch and 36-inch width mats, making it a practical choice for slightly wider doorways where a 24-inch mat leaves gaps at the edges. Each layer is made from low-density polyethylene film with a full acrylic adhesive coating, and a numbered tab system allows single-layer removal. Made with Purus's plant-based Cardia BioHybrid material and recyclable in conventional plastic streams.
Sold in cases of 4 mats.

Frequently Asked Questions
When should I choose a 26x45 mat over a 24x36 or 36x45?
The 26" x 45" size is a good fit for entryways that are slightly wider than a standard 24-inch mat but don’t require the full 36-inch width. It’s also useful when the 45-inch length is needed to ensure personnel take multiple steps on the adhesive surface before entering the controlled area. If your doorway measures 26–30 inches wide, this size provides better edge-to-edge coverage than a 24-inch mat.
Why choose white over blue or gray for a 26x45 mat?
White mats are preferred in environments where floor aesthetics matter, where specific color-coding protocols are in place, or where the mat needs to blend with light-colored flooring. They also work well in customer-facing or highly visible areas. Blue mats offer higher visual contrast for easier contamination monitoring if that’s a priority.
How do I know when to peel a layer?
Peel when the top layer is visibly soiled, or on a scheduled interval per your contamination control SOP. The numbered tab on the mat edge shows how many of the 30 layers remain so you can plan reorders before running out.
What makes Purus EnviroTack mats more sustainable than standard sticky mats?
Purus mats incorporate Cardia BioHybrid material — a GMO-free, renewable, plant-based additive that reduces CO₂ emissions compared to conventional LDPE mats. They are also recyclable in standard plastic recycling streams, unlike most sticky mats which go to landfill after use.
