Dimpled pads and rolls share the same features as our bonded (SM) pads without the added layer of spunbond. By not adding the extra layer of spunbond, it makes the pads more economical. The dimpling process increases the strength and durability of the pads so they can be perforated like a paper towel. Perforations will help reduce waste and allow you to use the exact amount needed for the job. Our dimpled meltblown sorbents are constructed of a single layer of dimpled meltblown polypropylene.
