  • Patent number: 11945194
    Abstract: The present disclosure provides a multilayer film. The multilayer film includes at least two layers including a sealant layer and a second layer in contact with the sealant layer. The sealant layer contains (A) a first ethylene-based polymer having a density from 0.895 g/cc to 0.925 g/cc and a melt index from 0.5 g/10 min to 30 g/10 min; (B) a branched fatty acid amide; and (C) a linear saturated fatty acid amide, wherein the branched fatty acid amide and the linear saturated fatty acid amide have a weight ratio of from 1:5 to 3:1. The second layer contains a second ethylene-based polymer.

  • Patent number: 5008133
    Abstract: A method of forming a coating on a web. A coating mixture includes a continuous phase of a first material and a second material contained in microcapsules. The first material and the second material interact to form the coating. The coating mixture is applied to a face of the web. The web is passed between a back-up member and a doctor blade so that the doctor blade levels the coating mixture on the web and crushes the microcapsules to cause mixing of the materials on the web to form the coating on the web.
