Described herein are recyclable films with an outer surface comprising a polar polymer, such as polyamide, an inner surface comprising a sealant, and a polar polymer compatibilizer located between the polar polymer and the sealant. Preferably the outer surface is an outer layer of biaxially oriented polyamide and the inner surface is a multilayer inner film comprising the sealant and the compatibilizer.

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.

A laminated sheet includes a substrate having sheet shape and a sealant layer provided on the substrate. The sealant layer includes a first resin layer containing a crystalline polyester, and a second resin layer located between the first resin layer and the substrate and containing no polyester, the second resin layer is joined to the substrate and the first resin layer, and a crystallization temperature of the crystalline polyester is 120° C. or higher and 150° C. or lower.

One or more implementations of a thermoplastic bag with a grab zone of deformations including raised rib-like elements positioned in a high-touch area of the bag. For example, the thermoplastic bag includes a hem skirt non-continuously laminated to a sidewall by one or more raised rib-like elements. The grab zone regions of one or more raised-rib-like elements are located in visible and high-touch areas to provide visual and tactile cues of strength and durability. Moreover, the grab zone regions of one or more raised rib-like elements serve to distribute pull and lift forces across a wider area in order to avoid common failures in high-touch areas such as over stretching, punctures, tears, and rips.

The present invention is directed to a monoaxially oriented, cross-linked multilayer film.

The invention is further directed to a method of producing and preserving a food product using such a film, bag or pouch and to a packaged food product obtained therefrom.

The present disclosure relates to a thermoplastic film that includes a layer of thermoplastic material and a color indicator applied to the thermoplastic material. The color indicator can be configured to change color in response to a trigger. For example, the color indicator can change color (e.g., change from a first color to a second color) in response to a color change trigger, such as exposure to malodor particles, absorption of moisture, a length of time, or as a result of oxidation. In one or more embodiments, the thermoplastic film further includes an odor control component configured to mask, neutralize, or otherwise control malodors. The color indicator can change its color appearance as the odor control component performs to control any present malodors, thus signaling the performance of the odor control component.

The present invention refers to a polymeric film comprising odor barrier material and being able to pack malodorous waste.

The invention provides a polyolefin-based resin film formed from a polypropylene-based resin composition and containing, in a total of 100 parts by weight of the polypropylene-based resin composition, 20-95 parts by weight of a propylene-α olefin random copolymer containing a metallocene-based olefin polymerization catalyst; 0-75 parts by weight of a propylene-α olefin random copolymer containing a Ziegler-Natta-based olefin polymerization catalyst; and 5-15 parts by weight of at least one type of an elastomer selected from the group consisting of an ethylene-butene copolymer elastomer, a propylene-butene copolymer elastomer, and an ethylene-propylene copolymer elastomer, wherein a heat shrinkage ratio in a direction in which a heat shrinkage ratio is larger among a longitudinal direction and a width direction of the polyolefin-based resin film is 1-10%, and an orientation coefficient ΔNx in an x-axis direction calculated from a refractive index of the polyolefin-based resin film is 0.0130-0.0250.

The present invention is directed to a packaging material, more specifically a packaging material having gas and/or moisture barrier properties, wherein the material comprises a barrier material comprising a layer comprising at least 50% of a zinc ionomer, a layer of polyethylene and a layer that forms a gas barrier. The invention is also directed to packaging products using said barrier material. Such products are in particular packages suitable for cosmetics and personal care products.

Provided are a fruit bag and a manufacturing method thereof, for example, a fruit bag for a fruit of a fruit tree may include: an inner surface configured to surround the fruit; an outer surface configured to exposed to an outside; an opening formed in a predetermined size at the same position of the inner surface and the outer surface; a nano membrane generated by an electrospinning of a polymer solution as a raw material for nano-fibers; a non-woven fabric for strength reinforcement laminated on one or both sides of the nano membrane and a nano-lamination film covering the entire surface of the opening thereby while maintaining excellent air permeability, it is possible to properly maintain the humidity and against various external environmental effects.
