A laminate structure includes an internal layer of foamed polymer. The foamed polymer replaces a paperboard layer used in prior laminate structures. Built upon the foamed polymer are three layers of low density polyethylene (LDPE), a layer of aluminum foil, and a tie layer. The foamed polymer may be polyethylene terephthalate (PET), polypropylene, high density polyethylene HDPE, LDPE, polystyrene, compositions comprising any of these polymers, or any other suitable foamed polymer compositions. The first LDPE layer coats a first surface of the foamed polymer, and the second LDPE layer coats a second surface of the foamed polymer. The aluminum foil layer is applied atop the second LDPE layer. The exposed surface of the aluminum foil is then coated with the tie layer, which is then topped with a third layer of LDPE. A non-polar homogeneous heat seal may be created at a temperature ranging from 250° F. to 500° F.

A moisture pad includes a porous pad, for example a sponge; a water bladder or reservoir; and a container for securely supporting the porous pad and the reservoir. Optionally, a lid may be provided as a closure for the container to reduce evaporation of the water. As another option, a strap can be provided for the container to allow the moisture pad to be worn on a person's body.

The invention discloses a freshness preservation method of medicinal materials. The freshness preservation method of the medicinal materials comprises the following steps: sorting harvested fresh medicinal materials, namely shearing and washing the fresh medicinal materials; carrying out sterilization treatment on the washed medicinal materials, and carrying out air-drying; contacting the dried medicinal materials with preservatives, and carrying out air-drying; and packaging the dried medicinal materials by using packaging materials. The freshness preservation method of the medicinal materials utilizes PBAT / PLLA composite ventilate film, so that water desorption of the fresh medicinal materials can be very well prevented, as well as effectively block pollution from the external environment. Being observed in bacteria tests which have been carried out for 1 month, the total colony numbers, the mold colony counts and the Escherichia coli counts of the medicinal materials preserved by using the method disclosed by the invention are all within the requirements of the national standards; thus, the method is capable of very well inhibiting growth of bacteria. Moreover, the preserved medicinal materials are good in appearance characteristics, and kept fresh. Small packages of fresh herbal medicines in small pieces ready for decoction are prepared by using the preserved medicinal materials.

An emulsion composition comprising: an aqueous component, a non-ionic block copolymer, and an oil wherein the copolymer comprises at least 10% by weight of the composition.

The invention provides an antibacterial preservative film. The antibacterial preservative film provided by the invention adopts a multilayer film structure comprising a back layer, a middle layer and a surface layer, wherein at least one layer of the multilayer film structure comprises a negative ion material. The negative ion material is added in the preservative film, and the released negative ions have high activity and a strong oxidation-reduction effect and can destroy the activity of cytomembrane or cellular plasm active enzyme of bacteria, so that the antibacterial and bactericidal aims are fulfilled, ethylene released by fruit and vegetables can be eliminated, nutrition self-consumption of the fruit and vegetables is relieved and the preservation time is prolonged; and the negative ion material also can improve the hydrophilicity of the film layer of the preservative film and avoids water loss of the fruit and vegetables. The experimental result indicates that the release speed of the negative ions of the preservative film provided by the invention can reach 10000 / cm<2>*min, and bacteria can be effectively resisted and killed.

Aspects of the disclosure include methods for treating hyperhidrosis in a subject with a composition including a muscarinic antagonist and a muscarinic agonist. In practicing methods according to certain embodiments, a therapeutically effective amount of a composition including a muscarinic antagonist or a pharmaceutically acceptable salt thereof and a muscarinic agonist or a pharmaceutically acceptable salt thereof is administered to a subject and is sufficient to reduce hyperhidrosis in the subject and to reduce a dry mouth side effect of the muscarinic antagonist. Compositions for practicing the subject methods are also described as well as dose units containing one or more of the subject compositions.
