Abstract:
A laminated packaging material biodegradable under uncontrolled composting conditions comprises a bioplastic sealant layer compostable under uncontrolled composting conditions, and a cellulose barrier layer compostable under uncontrolled composting conditions, wherein the barrier layer is bonded to the sealant layer with a water-based dry bond adhesive including a hydroxyl or an aziridine cross-linking coreactant and having polyurethanes or acrylics only in concentrations less than 0.1 % of the dry weight of the packaging material.
Abstract:
The present invention relates to a packaged hot-melt pressure sensitive adhesive comprising a hot-melt pressure sensitive adhesive composition and a coextrusion coating consisting of neat low density polyethylene, neat polypropylene, or neat ethylene vinyl acetate. The present invention further relates to the use of the packaged adhesive formed as individual forms in an adhesive application process, and the use of the packaged adhesive in the production of laminated articles, including nonwoven hygiene articles, disposable medical drapes, and also laminate constructions such as tapes and labels.
Abstract:
The presently disclosed subject matter is directed to a multilayer coextruded sterilizable film that can be used for aseptic packaging applications. The film comprises an outer layer comprising a blend of a cyclic olefin copolymer with a glass transition temperature of at least 80°C and an olefinic copolymer with a melting point of at least 125°C. The film has a storage modulus of at least 109 dynes/cm2 at temperatures of up to 140°C. An aseptic package and a method of making an aseptic package are also disclosed.
Abstract:
A method for manufacturing a non stick medical tube is provided. The method includes providing a first plastic resin to a tubing extrusion device and providing a second plastic resin to a tubing extrusion device, the second plastic resin comprising a medical grade amide compound. The method further includes mixing the first plastic resin with the second plastic resin and extruding the resin mixture such that the medical grade amide compound is present on an inner surface of the medical tube after extrusion to promote release of contacting surfaces of the inner surface of the medical tubing after contact.
Abstract:
Composition comprising: - at least one copolymer (A) of vinylidene chloride and of at least one comonomer copolymerizable therewith chosen from butyl acrylates; - from 1 to 20% by weight, relative to the total weight of the composition, of at least one polymeric plasticizer (B) chosen from polyesters derived from the polycondensation reaction of at least one aliphatic polycarboxylic acid and at least one polyhydroxylated aliphatic alcohol. The composition is suitable for the preparation of mono- or multi-layer films for the packaging of food products.
Abstract:
A noise dampening film is provided, and in particular, a film having at least one quiet layer that comprises a polymer resin and from about 5 to 50 weight percent of a styrene-vinyl polyisoprene-styrene block-co-polyisopyrene block triblock polymer. The quiet layer has a tan delta of at least about 0.27 or greater at a temperature range between about 17° C and 40° C.
Abstract:
A packaging material for forming at least a part of a package for a product releasing gasses comprises a one-way pressure relief valve (18) including a first inner film (10), being provided with at least one inlet opening (13,14) therethrough, and a second outer film (11) covering the at least one inlet opening (13, 14) and being bonded to the first inner film (10) to form a channel portion (12) between the inner and the outer film. The channel portion (12) communicates with the surroundings of the package through at least one outlet opening (15) spaced apart from the at least one inlet opening (13, 14). The pressure relief valve (18) further comprises a liquid (19) provided in the channel portion (12) and solid spacer means (17) provided in the channel portion (12) proximate to the at least one inlet opening (13, 14).The outer film (11) is a soft film having such a flexibility or elasticity that in a tensile test a force of less than 5 N is needed for elongating a test piece thereof having a width of 15mm by 5%.
Abstract:
A multilayer structure comprises at least one barrier layer comprising at least one vinylidene chloride polymer, at least one UV protecting layer, and at least one reflective layer wherein none of these layers also serve as a sealing layer. The multilayer structure is preferably a film, more preferably in the form of a pouch, preferably for packaging flowable product, especially milk. When used as a milk pouch, the structure is more effective at protecting milk from deterioration at ambient temperature and humidity than is a similar multilayer structure having an ethylene vinyl alcohol barrier layer. The multilayer structure preferably has more than one reflective layers and is preferably in the form of a pillow pouch. The invention also includes a process comprising steps of (a) supplying at least one first composition comprising at least one vinylidene chloride polymer, at least one second composition comprising UV absorbing pigment or agent, and at least one third composition comprising at least one light reflective material, to a coextrusion die and (b) coextruding the first, second and third compositions as layers referred to herein after as the barrier layer, UV protecting layer, and reflective layer respectively.
Abstract:
A multi-layer film with harrier properties having one or more layers made from a bio- based film Is disclosed. In one aspect, the print web comprises a bio-based film. In one aspect. the barrier web comprises a bio-based film, hi one aspect, a bio-based adhesive adheres the print web to the barrier web, The bio-based film can include paper, PCR, polylactide or polyhydroxy-alkanoate. Unlike prior art petroleum-based films, the bio-based film of the present invention is made from a renewable resource and is biodegradable.
