Laminated film structure comprising at least one first film having a thin ceramic or metal coating, being laminated to a second film and whereby the laminated film structure is based on polyethylene only, i.e. polymers other than polyethylene are substantially absent and whereby the laminated film structure has good barrier properties

Systems, devices, and methods including: a first layer; a second layer; a pocket formed between the first layer and the second layer to receive a fingertip of a user; and an elastic layer disposed over a portion of the first layer or the second layer to secure the fingertip of the user.

The present invention relates to a dehumidification bag and a preparation method thereof. The dehumidification bag comprises a bag body including a first side sheet and a second side sheet, the side sheet comprises an air-permeability and/or a composite film, wherein at least all or part of at least one side sheet is an air-permeability film; a moisture-proof layer covers the outside of the air-permeability. The dehumidification bag provided by the present invention provides an air-permeability on the bag body, and adopts heat sealing between the outer surface of the air-permeability layer and the moisture-proof layer, so that the air-permeability and the moisture-proof layer are in close contact without moisture absorption, which effectively prevents damage during transportation and storage. In the process, the air-permeability is in contact with the air in the outer bag and the effect of the dehumidifier becomes poor or invalid; by setting the moisture-proof layer to be tearable, when the buyer uses the dehumidification bag, the moisture-proof layer can be torn off, which is convenient and fast.

The patch product comprises a membrane substrate suitable to be absorbed by the skin and based on natural polymers, as well as at least one active ingredient. It can be packaged in a wrapping comprising a support base, on which the patch product is placed, and a coating layer that acts as protection for the patch product.

An adhesive composition contains an acid anhydride group-containing oil or fat (A) and a curing agent (B) having a reactive group reactive with an acid anhydride group. A laminate is obtained by placing an adhesive layer between a first substrate and a second substrate, and the adhesive layer includes the aforementioned adhesive composition. A package is obtained by forming a bag from a laminate obtained by placing an adhesive layer between a first substrate and a second substrate, and the adhesive layer includes the aforementioned adhesive composition.

A packaging film including a protective layer, a first bonding layer, a metal layer. a second bonding layer and a sealing layer. The protective layer, the first bonding layer, the metal layer. the second bonding layer, and the sealing layer are sequentially stacked. The protective layer includes a polymer resin layer and a carbon material.

Uncured composite structures, cured composite structures, and methods of curing uncured composite structures are disclosed herein. The uncured composite structures include a structural layer that includes an uncured structural resin and a surface layer that includes an uncured surface resin. The cured composite structures include a cured structural layer that includes a cured structural resin, a cured surface layer that includes a cured surface resin, and an interface region between the cured surface layer and the cured structural layer. The methods include initially heating the uncured composite structure to an initial temperature to generate a partially cured composite structure. The initially heating is sufficient to gel the uncured surface resin but insufficient to gel the uncured structural resin. The methods also include subsequently heating the partially cured composite structure to a final cure temperature, which is greater than the initial temperature, to generate the cured composite structure.

Provided are barrier laminates including polyethylene which offer heat resistance and a wide sealing window. The laminates can be fully compatible with polyethylene recycling streams and can exhibit improved, maintained, or desirable properties in comparison to existing laminate structures that are not fully compatible with polyethylene recycling streams. The laminate comprises a multilayer film, a polyethylene film, and an adhesive. The adhesive adheres the multilayer film to the polyethylene film to provide the laminate.

A bale wrapping system includes an emitter configured to generate electromagnetic radiation within an emitted spectrum and a wrap. The wrap includes a melt layer containing an additive absorbent to at least some electromagnetic radiation within the emitted spectrum and a solid layer substantially free of the additive.

A multilayer barrier film for food packaging comprises an outer layer comprising a first polymeric material having a moisture vapor transmission rate (MVTR) of greater than or equal to 10 gram.Math.mil/100 in.sup.2/day; a first inner layer adjacent to the outer layer, the first inner layer comprising a first retortable grade ethylene vinyl alcohol (EVOH) copolymer; a second inner layer adjacent to the first inner layer, the second inner layer comprising a second polymeric material having a moisture vapor transmission rate (MVTR) of greater than or equal to 10 gram.Math.mil/100 in.sup.2/day; a third inner layer adjacent to the second inner layer, the third inner layer comprising a second retortable grade EVOH copolymer; and a sealing layer adjacent to the third inner layer; wherein the first polymeric material is not a retortable grade EVOH copolymer. Excellent recovery of oxygen barrier over time is achieved by these films and retortable containers made therefrom.
