A method for producing a carbon dioxide-containing hydrogel article including (1) to (3). (1) Preparing an article including a hydrogel that contains a water-soluble polymer, a cross-linking agent for the water-soluble polymer, and water, wherein a loss tangent of the hydrogel at 1 Hz in dynamic viscoelasticity measurement is 0.46 or greater. (2) Adjusting a composition of an ambient atmosphere of the article including the hydrogel such that a carbon dioxide gas concentration in the ambient atmosphere becomes 10 vol% or greater, and sealing the article including the hydrogel inside a package. (3) Making cross-linking of the hydrogel proceed until the loss tangent, at 1 Hz in dynamic viscoelasticity measurement, of the hydrogel in the article including the hydrogel becomes less than 0.46, and thereby obtaining a carbon dioxide-containing hydrogel article sealed inside the package.

The disclosure relates to a deep-drawing packaging machine with a forming station for deep-drawing trays into a film, a loading stretch for filling products into the trays, and a sealing station for sealing the trays. The deep-drawing packaging machine further comprises at least one vacuum cooling station which is disposed in a direction of transport upstream of the sealing station and which is formed for vacuum cooling the products placed into the trays along the loading stretch. The disclosure furthermore relates to a method for vacuum cooling products.

There is described a packaging apparatus (1) for forming a plurality of sealed packages (2) from a tube (3) of a web of packaging material (4) which is continuously filled with a pourable product. The packaging apparatus comprises a delimiting element (37) arranged, in use, within the tube (3) and being designed to divide the tube (3), in use, into a first space (38) and a second space (39). The packaging apparatus (1) also comprises a sterile gas supply device (43) for pressurizing the isolation chamber and the second space (39) by means of a respectively a first flow of sterile gas and a second flow of sterile gas.

The present disclosure relates to the technical field of packaging and discloses a packaging box including a box body, a reel, and a cutting device. The box body is provided with an accommodation cavity used for accommodating a vacuum bag roll, and is provided with a bag outlet; the reel is rotatably arranged in the box body, and is used for mounting the vacuum bag roll; the cutting device includes a cutting part which is slidably connected to the box body; a bag opening of the vacuum bag roll stretches out from the box body to the cutting part after passing through the bag outlet. The packaging box provided by the present disclosure is conducive to storage, transport, and cutting the vacuum bag rolls, meeting the requirements of the user for using vacuum bags.

An inflatable web is disclosed. The web includes first and second film plies sealed together via a plurality of generally transverse seals to define a first and second inflatable chambers and an inflation region. The chambers are inflatable with a fluid and operable to contain the fluid. The sealed plies have a first longitudinal edge and a second longitudinal edge. The web defines a separation region extending at least partially transversely across the web between the first and second inflatable chambers and is configured to facilitate separation thereof. The separation region includes a tear propagation line extending transversely across at least a portion of the web with an end of the tear propagation line terminating proximal to the first longitudinal edge of the web. The separation region includes a tear initiation feature including edges spaced apart from one another longitudinally to form a permanent opening in the web.

A system and method of providing a secondary means for removing thermoforming trim material from a continuous-loop clamping chain (202) having clamps (302) biased to engage a clamp grip surface (314). A cam (400), attached to a sprocket located downstream from a cutting station (114) but upstream from a forming station (102), provides an outer surface that engages a clamp release surface (306) as the link member (300) passes over the sprocket.

There is described a packaging apparatus (1) for forming a plurality of sealed packages (2) from a tube (3) of a web of packaging material (4) which is continuously filled with a pourable product. The packaging apparatus comprises an isolation chamber (10) separating an inner environment (11) containing a sterile gas from an outer environment (12). The packaging apparatus further comprises a delimiting element (48) arranged, in use, within the tube (3) and being designed to divide the tube (3), in use, into a first space (49) and a second space (50). The packaging apparatus (1) also comprises a pressurizing device (47) for pressurizing the second space (50) by means of a pressurized sterile gas. The delimiting element (48) is arranged within the isolation chamber (10).

There is described a packaging machine for producing sealed packages of a pourable product from a web of packaging material, the packaging machine comprises an isolation chamber having an inner environment and within which, in use, the web of packaging material is formed into a tube, a conduct assembly being in fluid connection with the inner environment; the conduct assembly defining and/or forming together with the inner environment at least a portion of a flow circuit of the packaging machine, a nitrogen distribution unit configured to inject and/or direct nitrogen into the flow circuit and a flow controlling device configured to create a flow of gas along a flow path within the flow circuit from the inner environment through at least a portion of the conduct assembly back into the inner environment.

The disclosure refers to a packaging device for manufacturing a packaging for a foodstuff. In particular, the packaging may include a trough-shaped lower packaging part and a top film which can be sealed together along their edges by means of a sealing tool of the packaging device. In order to improve a packaging device completely without evacuation or by evacuation in a simple and inexpensive manner with only a slight negative pressure in such a way that sufficient vapor purging is possible and at the same time cooling of the foodstuff before sealing or excessive degassing of the foodstuff does not take place, vapor can be introduced under pressure between the lower packaging part and the top film at at least one vapor entry point before sealing and can be released into the surrounding atmosphere at an outlet point from the packaging.
