Abstract: A compostable lid intended to seal a beverage capsule is provided. The lid is composed of a multilayer complex successively comprising a non-woven material wherein at least 50% by weight of the fibers are composed of polylactic acid (PLA), an adhesive layer suitable for coming into contact with food, and a support layer composed of a vegetable parchment.
Abstract: A fibrous media suitable for an oil filter comprising a fibrous web formed from synthetic fibers; optionally at least one additive, and a thermoset binder present at a concentration of at least 15 wt.-% by weight of the fibrous web and/or at least one binder fiber, wherein the synthetic fibers comprise up to 30 wt.-%, preferably up to 20 wt.-%, glass fibers, based on the total weight of the fibers. The fibers are bonded with the thermoset binder and/or the at least one binder fiber to form a web; and the fibrous media is capable of forming a self-supporting, pleated oil filter media which is capable of retaining pleats upon contact with oil having a temperature in the range encountered in a combustion engine.
