Embodiments of a laminate structure for use in flexible packaging comprise a sealant film comprising ethylene-based polymer, and a multilayer polyethylene print film laminated to the sealant film. The print film comprises at least 3 layers and has an overall thickness from 15 to 30 μm. The print film comprises a middle layer, an inner layer disposed between sealant film and the middle layer, and an outer layer, wherein the middle layer comprises at least 90% by weight high density polyethylene (HDPE) polymer having a density from 0.950 to 0.965 g/cc. The inner layer and the outer layer comprise linear low density polyethylene (LLDPE) having a density from 0.925 to 0.965 g/cc. The laminate structure yields desired optical and mechanical properties coupled with recyclability and improved printing efficiency, while maintaining these low thicknesses for the print film.

Multilayer thermoplastic films, and laminates and articles comprising the films, wherein the film comprises at least one inner layer and at least two outer layers, wherein the inner layer comprises a polymeric composition comprising from about 55% to about 95% of one or more non-hydrogenated styrenic block copolymers, olefinic block copolymers, or combinations thereof; and each outer layer comprises at least 20% polypropylene and has a thickness of from about 5% to about 15% of the total film thickness, and further wherein the film has a constant force tear propagation of about 20% or less.

Extruded starch compositions and methods for their preparation are provided. The compositions possess a high degree of cook which imparts particular viscosity characteristics. The compositions may be formed into films having advantageous properties such as low haze, high strength and high gas barrier. The starch compositions find use in a wide range of applications, particularly, but not exclusively, in the manufacture of thin films for packaging.

A multilayer film that includes at least a first polymeric layer comprising a polyolefin-based polymer and a second polymeric layer comprising a blend of a polar polymer and a silicon (Si) containing material comprising a silane having at least one alkyl group having at least 6 carbon atoms (C6) is disclosed. Methods of using and making the multilayer film is also disclosed.

The adhesive composition comprising emulsion polymers and microspheres and articles made therefrom are provided. The adhesive is particularly suitable for packages for consumer products that provide sufficient strength and thermal insulation while reducing the overall basis weight of the substrates.

The present invention relates to a mono or multi-layer polyester film, a process for producing the mono or multi-layer polyester film, an article comprising the mono or multi-layer polyester film as well as the use of the mono or multi-layer polyester film packaging products, insulating materials, solar, marine or aviation applications, science, electronic or acoustic applications, wires, cables, radio frequency identifications, flexible circuits, graphic arts, stone paper, holograms, filter products, cosmetic products, household products imaging, recording media, or industrial products.

The present invention is directed to a novel co-extruded multilayer structure that possess a draw down ratio superior than the critical draw-down ratio of each one of the polymeric layers, extruded individually. The present invention is also directed to a method for obtaining the co-extruded multilayer structure.

The co-extruded multilayer structure obtainable by the method described herein allows preparing films, filaments or spun-melt non-wovens of low weight at high speed using conventional extrusion equipments. The co-extruded multilayer structure is especially suitable as diaper back-sheets or flexible packaging coatings.

A recyclable, laminated polyolefin-based film structure comprises two or more film plies laminated to each other. Each of the laminated film plies comprises one or more polyolefin-based films. The film structure has an energy-cured coating layer disposed on the outermost outward facing surface of the film structure and a printed ink layer on an interior surface of one of the polyolefin-based polyolefin layers. In certain embodiments, the outermost surface of the laminated polyolefin-based film structure has a melting temperature which is at least 100 degrees Celsius, and more preferably 180 degrees Celsius, higher than a melting temperature of the innermost surface of the laminated polyolefin-based film structure.

Thermoplastic films and bags include gradient patterns of post-formation deformations. The gradient patterns of post-formation deformations can provide a connotation of strength. Additionally, the gradient pattern of post-formation deformations can provide different areas of the films or bags with different physical characteristics such as tear resistance, puncture resistance, elasticity, etc.
