Herb, Hemp and Cannabis Film
Polymer or polymer inks are used for reducing or eliminating harmful chemicals by offering a neutralizing chemical in the path of movement of the harmful chemicals. A neutralizing chemical responsive to the harmful chemical produces a harmless chemical as an output that is in the path of the harmful chemical and is opposite phase with the neutralizing chemical, preferably by 180 degrees, or is at least opposite in chemical compatibility to some extent. The neutralizing chemical can be suspended or combined with an inert carrier and preferably attenuates the harmful chemical concentration. The polymer ink can be applied to a media such as paper, (embossed or extruded) or polymer the same as paper but also in foam (open cell preferred) in order to obtain a decrease in the concentration of harmful gases. These forms can be utilized in air or liquid applications. Uses can be as diverse as but not limited to interior cleansing of boxes, cartons, and containers to air conditioning moving air applications in dynamic environments.
HEAT SEALABLE PACKAGING MATERIAL COMPRISING MICROFIBRILLATED CELLULOSE AND PRODUCTS MADE THEREFROM
The present invention is directed to a packaging material comprising a layer of microfibrillated cellulose (MFC) and an aluminum layer having a thickness of 0.1-20 m, wherein the layer comprising MFC and/or the aluminum layer has been laminated or extrusion coated on at least one side with a thermoplastic polymer and wherein the amount of aluminum is sufficient to make the packaging material heat sealable by induction. The MFC layer contains at least 60% by weight of microfibrillated cellulose.
METHOD FOR REDUCING THIN FILMS ON LOW TEMPERATURE SUBSTRATES
A method for producing an electrically conductive thin film on a substrate is disclosed. Initially, a reducible metal compound and a reducing agent are dispersed in a liquid. The dispersion is then deposited on a substrate as a thin film. The thin film along with the substrate is subsequently exposed to a pulsed electromagnetic emission to chemically react with the reducible metal compound and the reducing agent such that the thin film becomes electrically conductive.
