Abstract: Conventional atomic layer deposition technology is modified to increase its cost-effective viability for use in producing thinly coated flexible packaging film. In one embodiment a thinly coated flexible substrate, e.g., a polyolefin film, is made by a process comprising the steps of: (A) Dissolving a self-limiting precursor in a solvent to form a solution of dissolved self-limiting precursor in the solvent, (B) Applying the solution to a facial surface of a flexible polymer film so that at least a portion of the dissolved self-limiting precursor attaches to the facial surface of the film and the solution is at least partially depleted of self-limiting precursor, and (C) Curing the attached self-limiting precursor by contact with oxygen.

Abstract: The present disclosure relates a method to adjust the amount of elongation required to effect a color change in a polymer stretch film. A first aspect of the invention is a method which method comprises selecting a polyolefin resin having a given density; admixing a given amount of the AIE mechanochromic dye into a melt of the polyolefin resin; making a film of a desired thickness from the polyolefin resin containing the mechanochromic dye; determining the level of elongation needed to effect a color change in the resulting film; and adjusting the density of the polyolefin resin to change the level of elongation needed to effect the color change to the desired level.

Abstract: The present disclosure relates to a multilayer stretch film comprising at least a first layer, wherein said first layer comprises a polyolefin resin. The film of this aspect of the disclosure further include at least a second layer, and a mechanochromic dye which may be in any or all layers of the film. Another aspect of the disclosure is a method of promoting optimal stretching of stretch film during a wrapping operation, which method comprises at least the following steps. A polyolefin resin is selected that has a given density. Selecting a mechanochromic dye based on its ability to agglomerate in an unstretched film made from the polyolefin resin having the given density, such that when the dye is included in the film, the unstretched film will exhibit a first color. Admixing the mechanochromic dye into a melt of the polyolefin resin. Forming a film from the admixture of the previous step. Wrapping an object using the film of the previous step, while stretching the film to a level where a change from the first color to a second color can be observed.

Abstract: The present invention relates to a method for flocculating and dewatering oil sands fine tailings. Said method comprises mixing the aqueous mineral suspension with a poly(ethylene oxide) (co)polymer to form a dough-like material. The material is then dynamically mixed in an in-line reactor to break down the dough-like material to form microflocs having an average size of 1 to 500 microns, and to release water. The internal diameter of the in-line reactor is at most five times the internal diameter of the inlet pipe of the reactor. The suspension of microflocs has a viscosity of at most 1000 cP and a yield stress of at most 300 Pa.
