Why Choose the 60-Layer Version?

The Purus International EnviroTack™ PM 3660 64 B delivers twice the usable life per mat compared to the standard 30-layer version — making it the preferred choice for high-traffic entry points where mats need to be changed frequently, or for facilities looking to reduce the frequency of mat replacement and the associated labor cost. With 60 numbered, peel-off layers per mat and 4 mats per case, each case provides 240 total sheets of contamination control coverage.

Like all Purus EnviroTack™ mats, the PM 3660 64 B incorporates renewable, plant-based Cardia BioHybrid™ material in the LDPE film, reducing CO₂ emissions compared to conventional petroleum-based mats. The acrylic adhesive delivers reliable regular-tack performance, and the numbered tab system ensures clean, one-layer-at-a-time removal. Used mats can be recycled in conventional plastic recycling streams.

Applications

• Facilities looking to reduce mat replacement frequency and labor
• Cleanrooms: microelectronics, biotech, semiconductor, pharma production
• Pharmaceutical compounding (USP 797)
• Hospitals: operating environments, ICU centers
• Data centers, nuclear facilities, industrial workspaces

Frequently Asked Questions

What is the difference between the 30-layer and 60-layer versions?
The 60-layer version (PM 3660 64 B) provides twice as many peel-off sheets per mat as the 30-layer version (PM 3660 34 B), doubling the usable life per mat. The 60-layer film is slightly thinner at 1.4 mil / 35 μm vs. 1.8 mil / 45 μm for the 30-layer, but adhesive performance is equivalent.

How many total sheets come in a case?
Each case contains 4 mats of 60 layers each, for a total of 240 peel-off sheets per case — double the 120 sheets in a 30-layer case.

What makes Purus EnviroTack mats eco-friendly?
Purus EnviroTack™ mats incorporate GMO-free, renewable, plant-based Cardia BioHybrid™ material in the LDPE film, reducing CO₂ emissions vs. conventional mats. Used mats can be recycled in conventional plastic recycling streams.

Is a high-tack 60-layer version available?
The high-tack option is available in the 30-layer format (PM 3660 34 B-HT). For maximum particle capture with extended mat life, the 60-layer regular-tack version is the recommended choice for most high-traffic cleanroom applications.

What colors are available in the 60-layer version?
The 60-layer series is available in Blue (PM 3660 64 B), White (PM 3660 64 W), and Gray (PM 3660 64 G).
