    Abstract: The present disclosure relates to a multilayer film including polyalkylene carbonate, and more particularly to a multilayer film including a core layer prepared by blending polyalkylene carbonate and an ethylene vinyl acetate copolymer in a predetermined ratio, and an outer layer of polyolefin. The multilayer film does not have delamination behavior because two layers are adhered each other with a simple process without an additional step for introducing an oxygen-barrier layer even without adhesive or tie layers, and has an excellent oxygen barrier property. In addition, since an additional process for imparting barrier properties and a separate adhesive or tie layer are not required in the manufacturing method, the cost can be reduced and the layer structure can be simplified, which may greatly reduce the manufacturing cost.

  • Patent number: 10710343
    Abstract: Multilayered polymer films are configured so that successive constituent layer packets can be delaminated in continuous sheet form from the remaining film. The new films are compatible with known coextrusion manufacturing techniques, and can also be made without the use of adhesive layers between layer packets that are tailored to be individually peelable from the remainder of the film. Instead, combinations of polymer compositions are used to allow non-adhesive polymer layers to be combined in such a way that delamination of the film is likely to occur along a plurality of delamination surfaces corresponding to interfaces between particular pairs of layers for which the peel strength is reduced relative to the peel strength at other layer interfaces within the film. The absence of an adhesive between peelable layer packets results in the delamination being irreversible.

The compliant member shows adhesion to the engineered surface when the compliant member is within a pre-selected range of hardness. In some embodiments, the compliant member comprises a polymeric member, a thermoplastic elastomer, silicone, polyurethane, or a combination thereof.

  • Patent number: 9452592
    Abstract: The present invention is directed to a multilayer film having an active oxygen barrier layer that comprises an oxygen scavenging composition that is a blend of a thermoplastic resin (A) having carbon-carbon double bonds substantially in its main chain, a transition metal salt (B), and an oxygen barrier polymer (C) having oxygen barrier properties that can be further enhanced by exposing the composition to a source of ionizing radiation e.g., electron beam radiation. Irradiation improves the oxygen scavenging abilities of the oxygen scavenging composition so that oxygen can be intercepted and scavenged as it passes through the film. The resulting irradiated multilayer film has improved active barrier properties in comparison to the same film prior to irradiation. As result, the multilayer film of the present invention can be used in packaging applications to help maintain a low oxygen atmosphere in the interior of a package.

  • Patent number: 9335187
    Abstract: Pressure indicator pressure sensitive adhesive may contain microspheres that burst and release indicator when subjected to pressure and thereby produce a detectable indication of how much pressure has been applied when forming an adhesive joint between opposing structures. Electronic device structures can be assembled using the pressure indicator pressure sensitive adhesive. A camera or other sensor may monitor joint formation. The camera can gather infrared image data, visible light image data, or ultraviolet light image data. Sensor data such as magnetic or ultrasonic sensor data can also be collected on an adhesive joint. Joint inspection can be performed on test structures and production structures and corresponding adjustments made to the joint formation process. Positioners and other equipment that compresses the pressure indicator pressure sensitive adhesive can be adjusted in real time or calibrated using information about the condition of the pressure indicator pressure sensitive adhesive.
