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.

A peelable lid system includes a peelable lid, a seal configured to seal the peelable lid to a container, a handle coupled to the peelable lid, and a lifting mechanism coupled to handle. The lifting mechanism can be coupled to the peelable lid at a plurality of attachment points, including at least one attachment point coupled to the peelable lid away from the handle. The lifting mechanism can be configured to lift at least one portion of the peelable lid near each of the plurality of attachment points.

Provided is a self-adhesive sheet including a 4-methyl-1-pentene-based polymer. In the self-adhesive sheet, it is preferable that at least one or more temperatures showing a local maximum value of a loss tangent (tan δ) , which is obtained by dynamic viscoelasticity measurement under conditions of a temperature rising rate of 4° C./min, a frequency of 1.59 Hz, and a strain amount of 0.1%, are present in a range of 10° C. or higher and 100° C. or lower, the local maximum value of the loss tangent is 0.5 or more and 3.5 or less, an arithmetic average roughness Ra on one surface of the self-adhesive sheet is in a range of 0.01 to 10 .Math.m, and a ten-point average roughness Rz is in a range of 0.1 to 50 .Math.m.

A laminate comprising: a gas barrier layer (I) comprising a modified starch (A) having an average amylose content of 45% by mass or more and a water-soluble polymer (B); and a substrate (II) adjacent to the gas barrier layer (I), wherein the laminate exhibits a degree of biodegradation of 80% or more in a biodegradability test in accordance with ISO 14855-1.

Closure device includes a closure cap, which can be screwed onto the threaded connection of a container, forming a fillable capsule that is open at the bottom, on which a seal directed downward is sealed. Upper side of the part of the closure cap which forms the capsule is designed to be deformable and can be pressed axially downward. A press element is molded on this cover of the closure cap at the bottom. By pressing the cover downward, the downward-directed seal of the capsule is broken open by the press element. Seal is made from a laminate comprising a carrier material with a thickness of at least 0.5 mm. Subsequently, a barrier film is sprayed or laminated on the carrier material. The crimping forms a circumferential edge, by means of which the seal can be sealed to the capsule edge, on the inner side of the carrier material, with respect to the capsule, and resting on same. The carrier material has pre-notches in the form of cuts, which approximately cut through the carrier material yet leave the attached films intact.

In a pressure auto-adjusting package for a heated food and a composite membrane thereof, the composite membrane includes a first membrane coated with a partial release layer thereon in a predetermined width, a second membrane provided with a cutting line corresponding to the partial release layer, and a glue layer disposed between the first membrane and the second membrane to glue the first membrane and the second membrane together, the first membrane and the second membrane are pseudo-glued at the position of the partial release layer, the cutting line of the second membrane is disposed at a heat seal opening and extends to the accommodating space. The package has a pressure generated therein when being heated, the pressure enters into a pseudo-glued area between the second membrane and the first membrane from the cutting line to form a gap where the pressure is released to prevent explosion.

A filter medium includes first and second porous films mainly containing fluororesin, and a pre-collection member upstream of the first film. The second film is downstream of the first film. The pre-collection member has a pressure drop when air is passed through at a flow rate of 5.3 cm/s of between 15 Pa and 55 Pa, a collection efficiency of NaCl particles having a particle diameter of 0.3 μm when air containing the particles is passed hrough at a flow rate of 5.3 cm/s of between 25% and 80%, a thickness of 0.4 mm or less, and a PF value between 7 and 15. The PF value={−log((100−collection efficiency (%))/100)}/(pressure drop (Pa)/1000). A ratio of the PF value of the pre-collection member to the PF value when the first and second films are overlapped, is between 0.20 and 0.45. The filter medium can be used in a filter pack or filter unit, and may be produced by integrating the first and second films and the pre-collection member using heat lamination.

A method for manufacturing a container seal having an integral pull tab comprises providing a surface layer, an elastic layer, a top layer, an aluminum foil intermediate layer, and laminating a sealing adhesive layer of an adhesive thermoplastic resin or viscous agent to the intermediate layer. An adhesive surface and a non-adhesive portion are added to the thermoplastic resin layer, and placed on the aluminum foil to form a container seal laminate. The container seal laminate is cut to conform with an opening of the container to be sealed. The seal has an integral pull tab.

Devices, cartridges, and method are described herein for emulating smoking wherein a device generates an aerosol for inhalation by a subject by heating a viscous material that can have a tactile response in the mouth or respiratory tract, while reducing Hoffman analytes and mutagenic compounds delivered to the user as compared to a common tobacco cigarette.

This invention relates to a polymer composition that is particularly suitable for use in the manufacture of thermoformed articles, which can be biodegraded in industrial composting. This invention also relates to a process for the production of the said composition and articles obtained thereby.
