Frequently Asked Questions
What is the difference between regular tack and high tack EnviroTack mats?
High tack mats have a peel adhesion of 9.25 oz / 250 g per 25mm (±40), compared to 6.5 oz / 190 g per 25mm (±40) for regular tack. High tack is recommended for environments with heavier foot traffic, equipment wheels, or where maximum particle capture is required. Both versions use the same LDPE film and acrylic adhesive construction.
How do I remove layers from the EnviroTack mat?
Each mat includes a low-profile numbered tab on the edge that indicates the number of remaining layers. When the top layer is saturated with contamination, peel it back from the tab end and discard it — the numbered tab ensures one layer is removed at a time, revealing a fresh adhesive layer underneath. The tab number counts down so you always know how many clean layers remain.
What makes Purus EnviroTack mats environmentally friendly?
EnviroTack™ mats contain Cardia BioHybrid™ material — a GMO-free, renewable plant-based content that reduces CO₂ emissions compared to conventional petroleum-based polyethylene film. The mats can also be recycled in conventional plastic recycling streams. This makes them suitable for organizations with sustainability commitments or green procurement requirements.
What size and layer options are available for EnviroTack mats?
EnviroTack mats are available in 24 x 36 in size in 30-layer (4/case and 8/case) and 60-layer (4/case) formats, in white, blue, and gray colors, in both regular tack and high tack adhesion levels. Contact MTE Solutions for the full range of available configurations.
How should EnviroTack mats be positioned at a cleanroom entrance?
Place the mat directly at the cleanroom entrance threshold so that personnel and equipment wheels must cross the full mat surface before entering the controlled area. For high-traffic entrances, consider using multiple mats in series or the high tack version for maximum particle capture. Replace the top layer when it appears visibly contaminated or per your facility’s contamination control protocol.
