The present invention relates to the use of dual ovenable biaxially oriented polyester films in vacuum skin packaging applications. Furthermore, the invention relates to preferably dual ovenable skin packages, in particular to preferably dual ovenable vacuum skin food packages for cook-in applications. Due to the very high formability, the VSP packages of the present invention do not show the defects of prior VSP ovenable packages such as self-sealing of the top web or unsealed areas around the packed product.

Crumb rubber obtained from recycled tires is subjected to an interlinked substitution process. The process utilizes a reactive component that interferes with sulfur bonds. The resulting treated rubber exhibits properties similar to those of the virgin composite rubber structure prior to being granulated, and is suitable for use in fabricating new tires, engineered rubber articles, and asphalt rubber for use in waterproofing and paving applications.

The present disclosure is directed to peelable, heat-sealable lidding films for containers of diverse polymer compositions storing various products such as foodstuffs and pharmaceuticals. The lidding films disclosed herein can be heat-sealed to crystalline polyester trays (CPET), easily peeled, and contain improved antifogging performance by incorporating a non-migratory antifogging additive into the heat sealable layer of the film without deteriorating seal strengths.

A material sheet is formed of a woven fabric of polymer tapes, wherein the width of a tape varies less than 2% on average in the longitudinal direction of the tape. Processes for the preparation of the material sheet, and to a ballistic resistant article comprising the material sheet are also provided. A ballistic resistant article which includes the material sheet exhibits excellent antiballistic properties.

A retaining device, includes a base (51) extending in a longitudinal direction and presenting a top face (511) and a bottom face (512); and a plurality of retaining elements extending from the top face (511) of the base (51), each of the retaining elements being formed by a stem (52) surmounted by a head (53), the stem (52) having a bottom end (521) connected to the base (51), and a top end (522) opposite from the bottom end (521), the head (53) surmounting the top end (522) of the stem (52), and having a bottom face facing towards the base and a top face opposite from the bottom face.

The present invention addresses a compostable multilayer membrane (10) for cartridges containing soluble products or products adapted to be brewed by pressurized water or other fluid, comprising a first barrier layer (11) containing a compostable barrier film, a first metallization layer (12), an intermediate layer (13) containing at least one adhesive, a second barrier layer (14) containing a compostable barrier film. The compostable multilayer membrane (10) is characterized in that it comprises a layer (18) adjacent to the first barrier layer (11), on a side opposite to that upon which the metallization layer (12) has been deposited, which comprises a heat-resistant lacquer, a second metallization layer (17) disposed between the intermediate layer (13) and said second barrier layer (14), said compostable barrier film of said first barrier layer (11) and said second barrier layer (14) not being made of paper, such that said compostable multilayer membrane (10) will have an OTR value of less than 0.5 cc/m.sup.2/day/atm. The application further relates to cartridges (1) for soluble products or products adapted to be brewed by pressurized water or other fluid, which comprise a container body (2) made of a biodegradable or compostable material, which defines a hermetically sealed volume (3) at two opposite bases (4, 5), in which the soluble or brewable product is held, and at least one compostable multilayer membrane (10) of the invention.

There is provided a co-injection molded multilayer structure comprising a barrier layer and outer layers laminated to contact with the barrier layer on its both sides, wherein the barrier layer is made of a resin composition (X) comprising an ethylene-vinyl alcohol copolymer (A) and an alkali metal salt (B) of a higher fatty acid, having a melting point of 250 C. or lower; the ethylene-vinyl alcohol copolymer (A) has an ethylene unit content of 20 to 60 mol % and a saponification degree of 90% or more, and a content of the alkali metal salt (B) in the barrier layer is 50 to 1500 ppm in terms of metal atoms; and the outer layers are made of a resin composition (Y) comprising an unmodified high-density polyethylene (F) and a maleic anhydride-modified polyethylene (G), and a maleic anhydride modification rate relative to the whole resin composition (Y) is 0.005 to 0.1 wt %. This co-injection molded multilayer structure has excellent adhesiveness, so that its oxygen barrier performance can be maintained even after being subjected to an impact due to falling or the like.

A method for making a sheet laminate for being pre-punched to a sheet lid for a container, comprising the steps of providing a base sheet layer, and coextrusion coating an additional sheet layer, which comprises a tie layer comprising polyolefin and a welding layer comprising polystyrene (PS), onto said base sheet layer, so that the tie layer is disposed between the base sheet layer and the welding layer. The additional layer is coextrusion coated onto the base sheet layer. A sheet lid with a similar structure may be manufactured by punching the sheet laminate. The sheet lid may be used to close a container to form a package.

Various enhancements of tabbed seals are provided herein with enhanced tab functionality. Such enhancements include a lacquer coating, such as one-part and two-part coatings, which can help minimize tab sticking to the lower laminate. Further, the lacquer can help decrease air bubbles under the tab and also provide visual enhancements to the tab.
