The Purus EnviroTack PM 3645 34 W is a 36" x 45" white cleanroom sticky mat designed to capture and contain dirt, dust, and particulate from foot traffic and wheeled equipment at controlled environment entryways. The wide 36-inch footprint provides full-width coverage for standard single and double-door entries, and the white color offers high visual contrast for easy contamination monitoring. Each mat features 30 peel-away adhesive layers of low-density polyethylene film with a regular-tack acrylic adhesive coating and a numbered tab for 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

What is the difference between the PM 3645 34 W and the PM 3645 34 W-HT?
Both are 36" x 45" white mats with 30 layers in a case of 4, but the W-HT is a high-tack version with a peel adhesion of 9.25 oz / 250 g/25mm versus 6.5 oz / 190 g/25mm for the standard W. Choose the W for typical foot traffic in ISO 6–8 environments; choose the W-HT for heavy wheeled equipment, high-traffic ISO 5–7 cleanrooms, or where maximum particle capture is required.

When should I choose a 36x45 mat over a smaller size?
The 36" x 45" size is ideal for wide single doors, double-door entries, or any entryway where a narrower mat would allow personnel to step around it. It’s also commonly used in front of gowning benches and equipment staging areas. If your doorway is 36 inches or wider, this size ensures full-width coverage with every step.

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 layers remain so you can plan reorders before running out. Most facilities peel on a time-based or traffic-count schedule rather than waiting for visible soiling.

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.
