HEAT AND SHOCK RESISTANT TRANSPARENT MEMBRANE
The present disclosure provides a multilayer structure including a first polyolefin layer comprising a first polyolefin resin, a gas barrier layer comprising ethylene-vinyl alcohol copolymer, and a second polyolefin layer comprising a second polyolefin resin. The present disclosure further provides a package made of the multilayer structure and also methods of use thereof.
Sealant film, laminate film, and packaging material
A sealant film is provided in which a surface resin layer (A), an adhesive resin layer (B), a release resin layer (C), and a heat seal resin layer (D) are laminated. The adhesive resin layer (B) contains a thermoplastic elastomer (b1) and a tackifier resin (b2). The release resin layer (C) contains 40% by mass or more of an ethylene ionomer (c1) with a polar group concentration exceeding 5.5 mol % in a resin component contained in the release resin layer (C). The release resin layer (C) further contains 0 to 60% by mass of an ethylene ionomer (c2) with a polar group concentration of 5.5 mol % or less in the resin component contained in the release resin layer (C). The heat seal resin layer (D) contains an ethylene resin (d1).
REPULPABLE AND RECYCLABLE COMPOSITE PACKAGING ARTICLES AND RELATED METHODS
A reusable, fiber containing pulp product is described that is highly suited for use in the manufacture of paper products. The reusable, fiber containing pulp product provides a mixture of fibers and small, dense polymer/particle fragments. The polymer/particle fragments within the reusable, fiber containing pulp product have a size range and density that facilitates efficient removal of the polymer/particle fragments using pressure screens.
Multilayer film with cyclic olefin seal layer
The present invention is related to a heat-sealable multilayer packaging film comprising: a support layer, and a peelable seal layer comprising a polymer blend, said polymer blend comprising: from 40 to 85% by weight of one or more first amorphous cyclic olefin polymer(s) characterized by a glass-transition temperature of at least 120° C., from 10 to 55% by weight of one or more second amorphous cyclic olefin polymer(s) characterized by a glass-transition temperature of less than 120° C., and from 0.5 to 15% by weight, preferably 0.5 to 10% by weight of at least one elastomeric copolymer comprising at least one polymerized monovinylarene and at least one polymerized acyclic olefin.
Polyester Terephthalate Rigid Wadding Disposed Between Surface Laminations
Wadding, insulation and packaging for food and other products is made of pure homogeneous polyester terephthalate (PET) that satisfies the resin recycling identification code number “1”. For purposes of protecting an inner wadding or other insulation, one or more film strips or film coatings may be applied by the artful use of amorphous (non-crystalized) PET or other types or configurations of PET, such that a filmstrip and/or wadding melts at a lower temperature and can act as a thermal bond adhesive. The film strips or film coatings may be made of homogeneous polyester terephthalate (PET) made of pure PET.
Transparent films based on resin components having a high glass transition temperature
Films having high light transmission values, low haze and high glass transition temperatures and useful, for example, as optical protection films and zero-zero optical retardation films, are prepared using one or more copolymers of methyl methacrylate having certain characteristics.
Functional fabric and method for producing functional fabric
A functional fabric is formed by bonding a polyester synthetic resin film mixed with carbon black fine particles to a fabric, in which the synthetic resin film is non-porous and has a thickness of 10 μm to 20 μm. The functional fabric is produced by producing a polyester synthetic resin film mixed with carbon black fine particles and bonding the synthetic resin film to a fabric, and the produced functional fabric is entirely or partially bonded to an inner wear or an intermediate clothes to produce clothing.
Composite structures for packaging articles and related methods
The composite structure includes a fiber-containing layer, such as a fiberboard layer or other layer having fibers from natural and/or synthetic sources, and a mineral-containing layer covering the fiber-containing layer. The fiber-containing layer and mineral-containing layer can be shaped, sized and manufactured such that the composite structure formed therefrom is capable of being machined to form a storage article. The composite structure has advantages in that it can improve whiteness, opacity, ink adhesion, materials reduction, barrier properties, recyclability, and printability. The composite can reduce polymer mass requirements for heat seal, barrier, and fiber adhesion. Further improvements include economics, pliability, and flexibility that is increased over the pliability of the fiber-containing layer alone.
Repulpable and recyclable composite packaging articles and related methods
A reusable, fiber containing pulp product is described that is highly suited for use in the manufacture of paper products. The reusable, fiber containing pulp product provides a mixture of fibers and small, dense polymer/particle fragments. The polymer/particle fragments within the reusable, fiber containing pulp product have a size range and density that facilitates efficient removal of the polymer/particle fragments using pressure screens.
Repulpable And Recyclable Composite Packaging Articles And Related Methods
Unexpectedly unique and environmentally friendly composite material structures, storage articles fabricated therefrom, and related methods. The composite structure includes at least one or more fiber-containing layers, such as fiberboard or other layers having fibers from natural and/or synthetic sources, and one or more mineral-containing layers. The mineral-containing layer(s) comprises a thermoplastic bonding agent fixing the mineral particles in place. The fiber-containing layer(s) and mineral-containing layer(s) can be shaped, sized, and manufactured such that the composite structure formed therefrom is capable of being machined to form the storage article. The composite structure can be repulped and recycled without the use of dispersions, emulsions, or aqueous solutions. Further, the composite reduces layer mass requirements for heat seal, barrier, and fiber adhesion compared to polymer layers. The composite structure further has tensile strength and other structural characteristics that allow it to be readily machined into desired storage article forms.
