Embodiments of the present disclosure are directed to multilayer films. Embodiments of the multilayer films may include a first layer comprising a polyethylene composition having a density of 0.924 g/cmto 0.936 g/cmand a melt index (I) of 0.25 g/10 minutes to 2.0 g/10 minutes, a second layer comprising a first polyolefin, a third layer comprising a second polyolefin. The first layer may be positioned between the second layer and the third layer. The first polyolefin and the second polyolefin may be the same or different.

Multilayer films having at least three layers and methods of producing the same

The present invention relates to oriented, multilayer polyethylene films. In one aspect, a biaxially oriented, multilayer polyethylene film comprises at least one layer comprising: (1) a polyethylene-based composition that comprises: (a) at least 97% by weight, based on the total weight of the polyethylene-based composition, of a polyethylene composition comprising: (i) from 25 to 37 percent by weight of a first polyethylene fraction having a density in the range of 0.935 to 0.947 g/cmand a melt index (I) of less than 0.1 g/10 minutes; and (ii) from 63 to 75 percent by weight of a second polyethylene fraction; and (b) 20 to 5000 ppm, based on the total weight of the polyethylene-based composition of a nucleating agent, wherein the nucleating agent comprises a calcium salt of 1,2-cyclohexanedicarboxylic acid or sodium 4-[(4-chlorobenzoyl) amino] benzoate; wherein the polyethylene composition has less than 0.10 branches per 1,000 carbon atoms when measured usingC NMR, wherein the density of the polyethylene-based composition is at least 0.965 g/cm, and wherein the melt index (I) of the polyethylene-based composition is 0.5 to 10 g/10 minutes.

Oriented polyethylene films and articles comprising the same

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.

Process for producing thin coatings on film

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.
