The present disclosure provides a film. In an embodiment, a film for suppressing odors is provided and includes a composition of (A) from 85 wt% to 99 wt% of a thermoplastic polymer and (B) from 15 wt% to 1 wt% of an odor suppressant. The odor suppressant is a blend composed of (Bi) particles of zinc oxide and (Bii) zinc ionomer. The zinc oxide particles (Bi) have a D50 particle size from 100 nm to 3000 nm, a surface area from 1 m /g to 9 m /g, and a porosity less than 0.020 m /g. The composition has a methyl mercaptan odor suppression value less than 70 at 3 days exposure to methyl mercaptan as measured in accordance with ASTM D5504-12. 本公开提供一种膜。在一个实施例中，提供一种用于抑制气味的膜，并且其包括(A)85wt％到99wt％的热塑性聚合物和(B)15wt％到1wt％的气味抑制剂的组合物。所述气味抑制剂是由(Bi)氧化锌粒子和(Bii)锌离子聚合物构成的掺混物。所述氧化锌粒子(Bi)具有100nm到3000nm的D50粒径、1m/g到9m/g的表面积和小于0.020m/g的孔隙度。如根据ASTM D5504-12所测量，所述组合物在暴露于甲硫醇3天时具有小于70的甲硫醇气味抑制值。
