A thermoplastic film which exhibits elastic-like behavior along at least one axis when stretched or elongated and then released. The thermoplastic film comprises a plurality of raised rib-like elements extending in a direction perpendicular to a main surface of the thermoplastic film. The thermoplastic film further includes a plurality of web areas positioned about the plurality of raised rib-like elements. The plurality of raised rib-like elements and plurality of web areas are arranged in a complex pattern. The complex pattern provides visual and tactile cues as the films are stretched or elongated. The complex pattern can cause the thermoplastic film to have a complex stretch profile.

A multiple-ply thermoplastic film which exhibits elastic-like behavior along at least one axis when stretched or elongated and then released. The thermoplastic film comprises a plurality of raised rib-like elements extending in a direction perpendicular to a main surface of the thermoplastic film. The thermoplastic film further includes a plurality of web areas positioned about the plurality of raised rib-like elements. The plurality of raised rib-like elements and plurality of web areas are arranged in a complex pattern. The complex pattern, when stretched or elongated and then released, can cause areas of billowing and delamination between plies of the multiple-ply thermoplastic film. The resulting billowed and delaminated areas form billow pockets for capturing liquids that can capture liquids when one of the plies is punctured.

Embodiments of the present invention relate to multilayer films, labels, and packages. In one aspect, a multilayer film having at least one matte surface comprises (a) an outer layer comprising (i) 30 to 99.5 weight percent of a first low density polyethylene having a density of 0.919 g/cm.sup.3 to 0.940 g/cm.sup.3 and a melt index (I.sub.2) of 0.3 to 5 g/10 minutes, (ii) 0.1 to 20 weight percent of polymer particles having a core and a shell structure wherein the core comprises a first polymeric material having a first refractive index and the shell comprises a second polymeric material having a second refractive index that is different from the first refractive index, and (iii) optionally, up to 50 weight percent of a first polyethylene having a density of 0.925 g/cm.sup.3 to 0.970 g/cm3 and a melt index (I.sub.2) of 0.8 to 10 g/10 minutes, each based on the total weight of the outer layer; and (b) a second layer in adhering contact with the outer layer comprising (i) 1 to 80 weight percent of a second low density polyethylene having a density of 0.919 g/cm.sup.3 to 0.940 g/cm3 and a melt index (I.sub.2) of 0.3 to 5 g/10 minutes, and (ii) 20 to 99 weight percent of a second polyethylene having a density of 0.925 g/cm.sup.3 to 0.970 g/cm.sup.3 and a melt index (I.sub.2) of 0.8 to 10 g/10 minutes, each based on the total weight of the second layer; wherein the outer layer has a gloss of less than 50% as measured by ASTM D2457 at an angle of 45°.

One or more implementations of a multi-film thermoplastic structure include a first film having a first appearance in contact with a second film having a second appearance at one or more visually-distinct contact areas arranged into a text. Wherein the one or more visually-distinct contact areas, cause the first film to take on the second appearance of the second film. In one or more implementations the multi-film thermoplastic structure comprises a thermoplastic bag and text comprises a suffocation warning.

The present disclosure relates to a reinforced thermoplastic bag (e.g., comprising a bag-in-bag). In one or more embodiments, the reinforced thermoplastic bag includes a reinforced portion at a top-of-bag area where users often apply an external force to lift or carry the reinforced thermoplastic bag. In these or other embodiments, a grab-zone reinforcement insert is positioned across one or both of a hem channel region and a grab-zone along an outer surface, an inner surface, or between layers of the reinforced thermoplastic bag. In one or more embodiments, the grab-zone reinforcement insert comprises multiple layers (e.g., of a non-woven material). For example, the grab-zone reinforcement insert includes a first and second layer formed by a fold. In other implementations, the grab-zone reinforcement insert includes separate, discrete layers. In one or more embodiments, at least a portion of the grab-zone reinforcement insert is positionally affixed via a hem seal.

The presently disclosed subject matter generally relates to recyclable insulation material for shipping containers, groceries bags, etc., machines for making the recyclable insulation material, and methods for the making the recyclable insulation material. In one aspect, a method of forming an insulation product may include forming a continuous sheet of paper into a plurality of flexible loops defining a plurality of air channels extending in a direction that is substantially perpendicular with a machine direction of the continuous sheet of paper. The method may also include immediately attaching a first layer of paper and a second layer of paper to the plurality of flexible loops as they are formed so that the continuous sheet of paper retains the plurality of flexible loops between the first layer and the second layer and that the plurality of flexible loops remain unattached with respect to one another.

The present disclosure relates to thermoplastics film, multi-film structures, and bags including enhanced physical properties. For example, one or more implementations include tailoring the physical properties of thermoplastic films by forming ribs using ring rolling in the films that extend at an angle relative to a direction in which the film is extruded (e.g., the machine direction). In other words, one or more implementations include films with a pattern of ribs extending at an acute angle to the predominate direction of molecular orientation of the thermoplastic film. The angled ribs increase the machine direction tear resistance of the thermoplastic film by intersecting any machine direction propagating tears and redirecting the tears towards the higher tear resistant transverse direction.

It is provided that a biaxially stretched polyamide film that has excellent resistance to pinhole formation due to bending, has excellent resistance to pinhole formation due to repeated contact, has excellent piercing resistance, and further can suppress generation of foreign matter during film formation. A biaxially stretched polyimide film comprising a functional layer (layer B) laminated on at least one surface of a base layer (layer A), wherein the base layer (layer A) contains at least (a) 70 to 99% by mass of a polyamide 6 resin, and (b) 1 to 20% by mass of an aliphatic or aromatic-aliphatic polyester resin, and the functional layer (layer B) contains at least 70% by mass or more of a polyamide 6 resin.

The present invention relates to an ornamental laminate film made from at least an inside film and an outside film, provided with a letter and/or a pattern by printing and as a raised part protruding toward the outside film. At least apart of the letter and/or the pattern has a metallic luster and differs in at least one of hue, brightness, chroma and glossiness from a region other than the letter and/or the pattern, and the raised part is formed along at least a part of the letter and/or the pattern. As a result of that, an ornamental laminate film with excellent design is provided without impairing its function as a packaging material.

A machine for making insulation may include two or more rotatory members configured to pull a precut insulation product at a first rate, wherein the precut insulation product comprises a first paper layer, a second paper layer, and a continuous paper core sheet, a first restraint and a second restraint spaced apart a predetermined distance to create a first space therebetween, and two or more second rotary members configured to feed a continuous paper sheet at a second rate into the first space such that the continuous paper sheet forms a plurality of flexible loops defining a plurality of air channels that extend in a direction that is substantially perpendicular with a machine direction. The first rate may be slower than the second rate.
