Reclosable package as well as thermoform packaging machine and method
A reclosable package, and a machine and method for making that reclosable package that includes a tray for receiving a product and a substantially horizontal edge, wherein the horizontal edge extends circumferentially on an upper side of the tray and has a clamping portion releasably connected thereto. The package includes a top film across the tray, the edge and the clamping portion, and which may be releasably connected to the edge by a first sealed seam to seal the tray in a gas-tight manner. The top film may be connected to the clamping portion by a second sealed seam. A side face of the tray may include an undercut provided with a projection, the projection being suitable for locking the clamping portion in position when the clamping portion has been detached from the edge and is located between the projection of the undercut and the side face of the tray.
Methods and apparatus for packaging products
Provided is a method and machine for packaging products, whereby a tray is generated by means of bonding a plastic film to a base film, the tray including a cavity of a given area and a rim surrounding the cavity. The cavity is generated by applying a given pressure on a forming area of the films. Before generating the tray and before pressing the base film, a support cut is generated in the forming area of the base film, such that with the subsequent pressure on the base film at least one gap is formed in the cavity of the tray as a result the support cut.

Right-sized thermoformed cavities for packaging items
An actuator system for fabricating a cavity within thermoplastic material includes a plurality of actuators arranged in an array. When dimensions of an item are determined, the actuator system may be programmed with data regarding such dimensions to fabricate a cavity for the item. A subset of the actuators, and distances by which each of the actuators is to be extended, may be selected based on dimensions of the item, in order to fabricate a cavity within the thermoplastic material that may accommodate the item therein. Additionally, the actuators and the distances may be selected based on intrinsic or extrinsic data regarding the item, and a cavity fabricated within the thermoplastic material may include one or more buffer zones or protective regions that are specifically formed with respect to aspects of the item.

METHOD FOR THE PRODUCTION AND FILLING OF CONTAINERS DESIGNED TO CONTAIN FOOD
A method for the production and filling of containers designed to contain food, includes the steps of shaping a sheet made of PET (polyethylene terephthalate) in order to provide accommodation receptacles provided with at least one access inlet; filling, through the access inlet, the accommodation receptacles with at least one food; sealing the access inlet using a closure film; and providing a weakened portion at a connecting edge between at least two adjacent accommodation receptacles.
The final degree of crystallinity at the weakened portion is lower than, equal to, or greater than, at most by a percentage equal to 3%, the degree of crystallinity of portions of the connecting edge not affected by modifications occurring as a consequence of the step of emission of laser radiation and of the sealing step.

Station for feeding closing seals and method of sealing containers for a packaging line
A station for feeding closing seals for containers includes at least one fixed magazine of seals which is provided with an outlet from which the seals can be taken individually. The station further includes a carousel for feeding seals which can rotate with respect to a first central rotation axis and is provided with pickers which are radially spaced apart from the first rotation axis. The pickers are individually rotatable about a second rotation axis which is not parallel to the first axis of the carousel. During rotation of the carousel, at least one picker is configured to rotate about the second axis from a position for taking the seal from the magazine to a position for releasing the seal.
Method and device for producing a packaging body of packaging
A method for producing a packaging body (51) from a web material that comprises paper, wherein the packaging body (51) comprises an indentation (53) for receiving an item to be packaged, the method comprising: pre-tensioning the web material (14); fixing the web material (14) between a holding-down device (32) and a die (31); molding the indentation (53) in the web material (14); and removing the molded indentation (53) from the die (31).
