Ambishield’s line of SMS coveralls is ideal for non-hazardous applications where a cost-effective disposable coverall is needed that offers a moderate barrier against dry particulates as well as light splash resistance. SMS (a three-layer material made by laminating a bottom layer of spun-bonded polypropylene, a middle layer of meltblown polypropylene, and a top layer of spun-bonded polypropylene) is more durable and offers a higher level of protection compared to standard spun-bonded polypropylene.
