Purus International PS 3645 64 B EnviroTack Adhesive Mat, 36x45, 60-Layer, Blue, Case of 4
Purus International PS 3645 64 B EnviroTack Adhesive Mat, 36x45, 60-Layer, Blue, Case of 4
The Purus EnviroTack PS 3645 64 B is a 36" x 45" blue cleanroom sticky mat with 60 peel-away layers — double the layer count of standard 30-layer mats — making it ideal for high-traffic entryways or facilities that want to extend time between mat replacements. The blue color provides high visual contrast for easy contamination monitoring, and the wide 36-inch footprint ensures full-width coverage for standard single and double-door entries. 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
What is the advantage of a 60-layer mat over a 30-layer mat?
A 60-layer mat lasts twice as long before the entire mat needs to be replaced, reducing changeover frequency and lowering the per-layer cost. For a large-format 36" x 45" mat, this is especially practical since the mat is more substantial to handle and store. High-traffic facilities or those with multiple entry points benefit most from the extended mat life.
Why choose blue over white for a 36x45 mat?
Blue mats provide higher visual contrast against light-colored floors, making it easier to see when the top layer is soiled and needs to be peeled. This supports consistent contamination control protocols without guesswork. White mats are preferred in environments with specific aesthetic requirements or where floor markings must remain visible beneath the mat.
Is the adhesive strength the same on 60-layer mats as 30-layer mats?
Yes — the adhesive type and peel adhesion (6.5 oz / 190 g/25mm for regular tack) are identical across both 30-layer and 60-layer EnviroTack mats. The only difference is the number of layers and the slightly thinner film per layer (1.4 mil for 60-layer vs. 1.8 mil for 30-layer 4/case configurations).
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.
