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 40°C to about 70°C, to a Tcg in the range of about 70°C to about 150°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.
摘要:
A process for packaging a product (P) arranged on a support (4) comprising unrolling a film (18), moving the film (18) to a packaging assembly (8) defining at its inside a packaging chamber (24), progressively moving a number of supports (4) inside the packaging chamber (24) of the packaging assembly (8), closing the packaging chamber (24) with the film sheets held above the respective support (4), optionally causing one or both of: a gas withdrawal from the hermetically closed packaging chamber (24) and gas injection of a gas mixture of controlled composition, heat sealing the film (18) to said support (4), wherein the heat sealing uses one or more heaters having heating surfaces which are heated for discrete and short time periods only. An apparatus (1) for performing the above process is also disclosed.

摘要:
Es wird ein Verfahren und eine Vorrichtung zur Herstellung eines Standbodenbeutels (1) als Beutelverpackungen aus einem Folienschlauch (3) vorgeschlagen, bei dem mindestens im Bereich des Bodens (4) des herzustellenden Standbodenbeutels (1) eine Faltung und Versiegelung von Teilen des Folienschlauchs (2) zur Herstellung eines weitgehend ebenen Bodens (4) durchgeführt wird. Innere Teile des Bodens (4) werden mit einem Formdruckstempel (5) flächig nach innen gedrückt, sodass ich eine Faltung im Randbereich des Folienschlauchs (2) ergibt, die sich zu einem umlaufenden Steg (7) herausbildet.

摘要:
A method for mutually blocking edges of elements of an item, in particular footwear, clothing and/or furniture items, comprising: frontal longitudinal cutting of edges (B1, B2) of a first and a second element (1, 2) of an item, to define respectively a first and a second flap (10 - 20, 11 - 21) in each of the edges (B1, B2); bringing together outer surfaces of the first flaps (10, 20) of the first and second element (1, 2); mutual blocking of the first flaps (10, 20) of the first and second element (1, 2); bringing together opposite inner surfaces of the first and second flaps (10 - 20, 11 - 21) such as to obtain a mutual blocking of the surfaces and a subsequent embedding of the first flaps (10, 20) between the second flaps (11, 21).
摘要:
A method for producing a filled hollow structure (20) includes producing an open hollow structure (20) of a first material, positioning the open hollow structure (20) on a tool (50) adapted to hold the open hollow structure (20), filling the open hollow structure (20) with a filler medium (60), and closing the filled open hollow structure (20) with a second material. A hollow structure (20) may be produced by such method, and a tool may be structured to perform such method.
