摘要:
The present invention provides a heat-sealable polyester composition having an amorphous processing window ranging from a Tg in the range of about 40null C. to about 70null C., to a Tcg in the range of about 70null C. to about 150null C. The composition preferably contains a mixture of poly(ethylene terephthalate) homopolymer or copolymer and poly(trimethylene terephthalate) homopolymer or copolymer, either as a physical blend or as a copolyester oligomer or polymer prepared from the respective monomers. The resulting composition is heat-sealable at low temperatures, retains barrier properties and is non-flavor-scalping.

A thermal imaging system for a battery module enclosure that includes first and second battery module enclosure components between which a weld is formed includes a thermal imaging camera that focuses on the first and second battery module enclosure components within a predetermined amount of time after the weld is formed and that acquires a thermal signature. A control module includes an image processing module that receives the thermal signature and that locates a predetermined reference point in the thermal signature. An image comparison module receives the thermal signature and uses the predetermined reference point to compare the thermal signature to a template signature in order to verify structural integrity of the weld. The image comparison module computes a relative measure of deviation of the thermal signature from the template signature and identifies the weld as defective when the relative measure of deviation is greater than a predetermined value.
摘要:
A method of joining two articles using slender nanomaterials is described. Randomly oriented nanomaterial mats or aligned nanomaterial arrays are introduced at the interface between the two articles followed by their energization via at least one of microwave irradiation and heating. The nanomaterial-to-nanomaterial and nanomaterial-to-surface contacts are enhanced by at least one of fusion, embedment and chemical reaction phenomena upon energization. The fusion, embedment and chemical reaction phenomena enhance at least one of the mechanical, electrical, thermal, durability and functional attributes of these contact points, which translate into improved properties of the joined article. The enhanced contact points enable effective use of the distinct qualities of nanomaterials towards development of joints which offer unique balances of strength, ductility, toughness, transport qualities, thermal stability, weathering resistance and other characteristics.

A peelable sealing structure includes a sealing layer and one or more optional additional layers. The peelable sealing structure includes a sealing surface that is formable into a peelable seal upon contact with a sealing substrate at all temperatures in a peelable seal temperature range. Moreover, the peelable sealing structure comprises a thermoplastic polymer and an additive dispersed within at least a portion of the thermoplastic polymer with the peelable sealing structure defining the sealing surface.

The present disclosure provides a method for detecting thermal sealing defects of a container during its transportation along a process line. The method is particularly suitable for containers caped with a cap liner and sealed with an inner seal. The method makes use of a high frequency heat (e.g. by a high frequency heat induction unit) to cause eddy current in the inner seal after which there is sensing by an IR imager of radiation emitted from the conductive innerseal to generate sensed IR image data indicative of the sensed radiation. The sensing is characterized by at least one of (i) a time window of a sensing session of between 50 msec to 300 msec during which said container is being transported through the FOV; and (ii) a sensing range of a wavelength spectrum region from 2 μm to 6 μm. The IR data is then processed so as to generate output data indicative of the presence or absence of at least one defect in the sealing of the container by said innerseal.

A method of making a decorated formed product effectively using a decorative sheet without diminishing the beauty of its appearance includes the steps of: (A) providing a formed product body; (B) mounting a first sheet, including an adhesive layer, on the formed product body; (C) heating a second sheet including a decoration layer and a base member that supports the decoration layer thereon; and (D) putting the heated second sheet on the first sheet, thereby bonding the second sheet onto the formed product body.
