AI Technical Summary

Benefits of technology

The proposed solution in this patent eliminates the need for additional elements in the sealing process and reduces the amount of material needed, resulting in cost savings. Additionally, the solution prevents damage to the second film by avoiding excess heat and reducing the amount of material disposed of. The use of thinner films also reduces material usage and packaging costs.

Problems solved by technology

Although with this solution it is not necessary to use additional material for supporting the films in the sealing station, the fact that the films are not held in the sealing station entails the need to use greater top film thicknesses to achieve suitable sealing, makes it necessary to perforate the inside of the package (the bottom film) to optimize sealing between both films and prevent creases and / or bubbles, and as the final package has been previously secured by its own flaps means, said holding can mark or damage said final package, which is not allowable and renders said solution to be unsuitable in many cases.

Embodiment Construction

[0026]FIG. 1 shows a schematic view of a skin packaging machine 100 according to one embodiment. The machine 100 is suitable for packaging products P arranged between a first continuous film 10 and a second continuous film 20 sealed to one another around the perimeter of the product P arranged between both by means of heat, and these are then cut for generating individual packages with a product P packaged therein. In some of the drawings the products P are not depicted for the sake of clarity.

[0027]Continuous must be interpreted as the films 10 and 20 being supplied without pre-cuts, i.e., without having been previously cut to the sizes required for the final package. Therefore, the films 10 and 20 can be stored in the form of reels, for example, and can be gradually unwound from the corresponding reel to be supplied.

[0028]The machine 100 comprises a first feeding station 1 for supplying the first continuous film 10 in a forward direction A of the machine 100, a second feeding stat...

Abstract

A skin packaging machine in which a first continuous film and a second continuous and thermoplastic film above the first film are supplied in a forward direction of the machine. The machine includes a sealing station configured for receiving both films, and it comprises an upper tool pressing on the films to seal them to one another, with a closed holding contour delimiting the area of said films being sealed. The sealing station further comprises a sealing gasket attached to the holding contour, the sealing gasket having, on each side with respect to the forward direction, an operation zone with a notched configuration which is facing the space delimited by said sealing gasket.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application relates to and claims the benefit and priority to European Application No. EP16382497.2, filed Oct. 28, 2016.TECHNICAL FIELD[0002]The present invention relates to skin packaging machines, by means of using a first film and a second film between which products are packaged.BACKGROUND[0003]The use of skin packaging machines supplying a first film on which products to be packaged are arranged and are then covered by a second film adhered to the first film by means of applying heat and pressure, for example, is well known. Packaging of this type is known also as skin packaging because it uses two films that are attached to one another around the contour of the product, one of which takes the form of the product, and is disclosed, for example, in patent document WO2015011076A1 belonging to the same applicant.[0004]The skin packaging of products is well known in the food industry for packaging meats, fish, cheese, ready-made me...
