Die Erfindung betrifft eine Tiefziehverpackungsmaschine (1) mit einer Formstation (2) zum Tiefziehen von Mulden (11) in eine Folie (9), einer Einfüllstrecke (12) zum Befüllen von Produkten (13) in die Mulden (11) und mit einer Siegelstation (4) zum Versiegeln der Mulden (11), dadurch gekennzeichnet, dass die Tiefziehverpackungsmaschine (1) in Transportrichtung (R) stromaufwärts der Siegelstation (4) mindestens eine Vakuumkühlstation (3) aufweist, die zum Vakuumkühlen der entlang der Einfüllstrecke (12) in die Mulden (11) eingelegten Produkte (13) ausgebildet ist. Ferner bezieht sich die Erfindung auf ein Verfahren zum Vakuumkühlen von Produkten (13).
摘要:
Process for packaging sticky substances in the molten state, in which the sticky substance is cast in a tray-mould lined be-forehand with a film of non-sticky plastic material and compatible in the fluid state with the sticky substance, including, among other, the phase of lining the internal walls of the tray-moulds with a first thin and easily formable film of the non-sticky plastic material, causing it to perfectly adhere to the walls of the mould by connecting the lower external part of the moulds connection to a vacuum source, in which the degree of vacuum during the opening transient of the connection is modulated.

The present invention relates to a process for preparing hot melt adhesive (HMA), preferably hot melt pressure sensitive adhesive (HMPSA), having a substantially tack-free coating, wherein said HMA, preferably HMPSA, can be easily handled, packed and transported for further use.
摘要:
A method for packaging plastic material using a film to surround the material, and more particularly to a method for packaging hot melt adhesives, the resulting package formed thereby, and the film composition used therein. The method is preferably a coextrusion process for packaging a pressure sensitive hot melt adhesive by extruding a hot melt adhesive through a die orifice, and coextruding a wax-based polymeric film to surround the hot melt adhesive. The coated adhesive may then be formed into individual packaged units having a finite size and shape. The polymeric film comprises a composition having at least 25% by weight of a wax material, and enthalpy of fusion of at least about 100J/g, and an elongation value at break of at least about 100%. Any type of hot melt adhesive formulation can be packaged or surrounded by the polymeric film in the process. Also, the specific enthalpy of fusion desired and/or elongation value at break desired for the polymeric film can be obtained by blending an appropriate amount of partially crystalline ethylene-based polymer together with a thermoplastic elastomeric block copolymer and/or an ethylene based or propylene-based elastomer.
摘要:
A process is provided for minimizing moisture accumulation in a product package that is sprayed with a cool water shower. The product is placed in a container (32), and a closure (36A) is installed on the container (32) to complete the package. The product is heated before it is placed the container (32), or during its placement in the container (32), or after it is placed in the container (32), or while the closure (36A) is being installed on the container (32), or after the closure (36A) has been installed on the container (32). The internal atmosphere within the closed closure (36A) is allowed to expand from the heat and to vent through a vent channel (81A). The package is cooled with a cooling water shower, and the vent channel (81A) minimizes the transient pressure differential so as to minimize the amount of water in filtration into the closure (36A).
摘要:
A method for processing a plastic container with a vacuum panel incorporated into the container body bottom, comprising: filling a container body with a hot product in a production line of container bodies, the container body having a projection extending from the container body bottom; sealing the filled container body in a subsequent operation of the production line; creating a vacuum in the container; and pushing the projection extending from the cooled container body bottom into the interior of the container body with a first actuator, wherein the container body with the projection extending from the container body bottom is supported by its neck during the filling and the sealing.
摘要:
The invention pertains to a method and an installation for packaging an adhesive product or similar products, the liquid adhesive product being sheathed in a protective sheath of a nonadhesive material. In addition, the adhesive product is sheathed in the protective sheath by means of a coextrusion process (30), the extruded product thus formed of the adhesive product and the protective sheath then being subjected to a solidification process (60), at least for the protective sheath.
