The invention relates to a packaging material for medical purposes. The packaging material comprises a packaging base material having an outer paper surface, a release lacquer that coats an entirety of the outer paper surface, and a sealing medium that is applied on the release lacquer in a grid pattern. The invention further relates to a method for producing the packaging material and its use.

In one aspect, a wallpaper alignment apparatus may include a first alignment unit and a second alignment unit. In one embodiment, each of the first and second alignment units is detachably disposed and aligned with the edge of the wallpaper through an adhesive. The first alignment unit has a first elongated main body and a plurality of protrusions extending from the first elongated main body. The second alignment unit has a second elongated main body and a plurality of recesses formed on the second elongated main body to receive corresponding protrusions on the first alignment unit to further align the wallpapers.

In some embodiments, the present disclosure pertains to substance detecting assemblies that include: (1) a sample medium (e.g., filter paper); and (2) a solid test chemical (e.g., zinc) impregnated with the sample medium. In some embodiments, the present disclosure pertains to methods of making an assembly for detecting a substance by: (1) providing a sample medium; (2) providing a solid test chemical; and (3) impregnating the sample medium with the solid test chemical. In further embodiments, the present disclosure pertains to methods for detecting a substance by: (1) collecting the substance on a sample medium that is impregnated with a solid test chemical; and (2) initiating a reaction of the substance with the solid test chemical on the sample medium to generate a color that corresponds to the substance. In some embodiments, the sample medium is then inserted into a chemical detection unit for the detection of the substance.

A pre-treatment fixing fluid for an offset coated medium is disclosed. The pre-treatment fixing fluid includes calcium-containing cationic crashing agents consisting of calcium propionate and calcium nitrate, wherein the calcium propionate is present in an amount ranging from about 0 wt % to about 10 wt %, and wherein the calcium nitrate is present in an amount ranging from about 15 wt % to 0 wt %, both based on the total wt % of the pre-treatment fixing fluid. The pre-treatment fixing further includes a co-solvent, a surfactant, and a balance of water. The surfactant is selected from the group consisting of a first surfactant having a first hydrophilic lipophilic balance (HLB) value within a hydrophobic range and a combination of the first surfactant and a second surfactant having a second HLB value within a water dispersible range.
