This invention relates to a process for reducing or eliminating organoleptic degradation in organoleptically sensitive foods packaged in flexible packaging, and packaged products thereof. This invention also relates to organoleptic flexible packaging made from polymeric films comprising oxidation-stable and non-migratory polysiloxane as slip additive. The oxidative-stability and non-migratory nature of the polysiloxane slip additive provides an organoleptic flexible packaging that is non-interactive with and inert to the organoleptically sensitive food packaged within, specifically: (1) coffee; (2) beer; (3) water; and (4) wine.

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 multilayer film having at least one barrier layer and at least one outer layer, suitable for medical applications, such as ostomy applications, which is effective as barrier for odors and has sufficient properties with respect to provide a pliable, tear resistant with noise damping film is provided. The multilayer film includes polyolefin elastomers, plasticized PVDC, ethylene vinyl acetate copolymers and additives.

A waterproof corrugated paper includes at least one stone paper medium and at least one stone liner paper, wherein the at least one stone paper medium includes a first fluting surface. A stone glue is utilized to adhere the at least one stone liner paper and several wave crests of the first fluting surface. The stone glue includes a linear polyolefin plastic material and an inorganic material. The linear polyolefin plastic material is 30 wt %-70 wt % based on the stone glue, and the inorganic material is 30 wt %-70 wt % based on the stone glue. The waterproof corrugated paper provided by the present invention is waterproof and frost-resistant, which is adapted to package cooled or frozen food. A manufacturing method, a manufacturing apparatus, and a usage of the waterproof corrugated paper are also provided in the present invention.

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 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.
