Multi-layer films and labels are disclosed herein. In an embodiment, a multi-layer film comprises a first skin layer, a first intermediate layer, a core layer, a second intermediate layer, and a second skin layer arranged sequentially, wherein the core layer has a thickness that is greater than thickness of the first or the second intermediate layers or the skin layer, wherein the core layer includes polybutylene terephthalate (PBT) particles disposed therein, wherein the amount of PBT particles ranges from about 5 to about 10 percent by weight (wt %), based on the total weight of the core layer, wherein the multi-layer film has a thickness ranging from about 25 microns to about 45 microns, wherein the core layer has a thickness ranging from about 20 microns to about 40 microns.

A compostable laminate for food wrap and method for making same. The wrap can include a first layer of paper material, a second layer of paper material, and a series of coatings between the paper materials. The coatings include a first flood coating having water and/or barrier properties, a second flood coating having water and/or oil barrier properties, and a third coating that only partially covers the second flood coating. None of the first, second and third coatings comprise a thermoplastic or polyolefin, and are made substantially from one or more biodegradable and/or compostable materials.

Described in this disclosure is a surface configured to break down deposits thereon. The surface may include breakdown structures, oleophilic structures, and hydrophilic structures. The oleophilic structures and hydrophilic structures are configured to disperse a deposit, such as fingerprint residue, to the breakdown structures. This dispersion increases the surface area of the deposit with respect to the breakdown structures, increasing the contact area between the two. The breakdown structures modify the deposit physically, chemically, or both, such that fragments are distributed into the ambient environment. The surface may be applied to portable electronic devices.

The present invention relates to multi-layer fiber products and a method of manufacturing these kinds of products. The present product comprises a first layer consists mainly of natural fibers and a second, heat-sealing layer located on top of the first layer. The heat-sealing layer consists mainly of synthetic thermoplastic fibers or particles. According to the present method, the heat-sealing layer is brought onto the first layer already during the web forming process, the first and the second layers being formed and joined together in a foam forming process. With the present invention, it is possible to decrease the amount of plastic materials in packaging materials having heat-sealing properties.

In one embodiment, a multilayer article can comprise: a multilayer substrate M, comprising: greater than or equal to 16 polymer A layers, preferably 16 to 512 polymer A layers; and greater than or equal to 16 polymer B layers, preferably 16 to 512 polymer B layers; wherein the polymer A layers and the polymer B layers are present in a ratio of 1:4 to 4:1, preferably the ratio is 1:1; a protective layer P; and an identification layer I between the protective layer P and the multilayer substrate M; wherein the identification layer I comprises information, and wherein the protective layer P prevents alteration thereof.

The present invention relates to a multilayer film including at least one film surface which has an increased surface roughness achieved by protrusion creating particles. The at least one film surface may have a surface roughness characterized by a coefficient of roughness (CR) of ≥0.02 or a Parker Print Surf roughness of at least 2 μm.

Disclosed are compositions, methods and uses for thin multi-layered films that may include a metallizable skin layer that include polyethylene polymer(s), wherein the metallizable skin layer may be treated one or more times. The multi-layered films include a core layer and a sealant layer, wherein each of these layers includes metallocene-catalyzed, linear, low-density polyethylene. The core layer is located between the metallizable skin layer and the sealant layer. These films may include one or more additives in any of the layers and/or include one or more tie layers. The multi-layered films may be biaxially oriented, have a haze equal to or below 5%, and have an elastic modulus equal to or below 350 N/mm.sup.2. The multi-layered films may also include a metallized layer on the metallizable skin layer, a coated layer on the metallizable skin layer, and/or be laminated to a polyethylene-based polymer, such as polyethylene terephthalate.
