Abstract: The present disclosure provides a dosing cap. In an embodiment, the dosing cap includes (A) a collar member having an annular skirt depending from a base. An inner surface of the annular skirt has a securing member for securing the collar member to a neck of a container. The base includes (i) at least one opening with a one-way valve permitting fluid flow in a first direction, and (ii) an air channel with a one-way valve permitting fluid flow in a second direction. The dosing cap includes (B) a cap member having an annular sidewall extending from a dispensing element. An inner surface of the annular sidewall has an attachment member adjustably attached to a reciprocal attachment member on an outer surface of the first sidewall. The dosing cap includes (C) a metering chamber formed by an enclosed volume between the cap member and the base. The dosing cap includes (D) the dispensing element permitting flow of a fluid from the metering chamber.

Abstract: The present disclosure provides a film. In an embodiment, a multilayer film having at least three layers is provided. The multilayer film includes two skin layers, each skin layer composed of a blend of a low density polyethylene and an ethylene-based elastomer having a density less than 0.90 g/cc. The multilayer film also includes a core layer located between the skin layers. The core layer includes a propylene-based plastomer having a density less than 0.90 g/cc. The multilayer film has an onset end temperature from 90° C. to 110° C. and a heat seal strength at 120° C. from 1.5 N/cm to 2.5 N/cm.
