Definitions
- the invention relates to the field of decorated packaging obtained by shaping a support carrying a preformed decoration.
- the decoration of the packaging obtained by shaping a strip or sheet material is generally carried out in two main ways:
- a metal strip is shaped by stamping and drawing, then the box body obtained is decorated, for example by an offset process.
- the metal strip is generally decorated by wet offset printing, and the decorated formats are then shaped by stamping.
- the printed image is a preformed image, so as to restore, after shaping, the desired image, as indicated in European application EP-A-0371897.
- PROBLEM POSED The process according to the state of the art has several drawbacks: on the one hand, the metal sheets to be decorated being relatively thick, of the order of 0.20 mm, the printing of formats, and not of tape , in wet offset is, in practice, only implemented industrially, on specific printing lines, - on the other hand offset inks require baking at high temperature and for a relatively long time (several minutes around 180 ° C for example). It may also be necessary to carry out an additional over-coating pass to protect the inks against physical (scratch) or physicochemical attack (action of water or steam in a sterilizer),
- the method of manufacturing printed packaging by shaping a support carrying a pre-deformed decoration is characterized in that, a) printing in reverse decoration on a plastic film F said pre-deformed decoration with inks adhering to said plastic film, so as to obtain a multilayer printed film symbolized by F / D in the form of a reel, b) assembling said support S and the multilayer printed film F / D, so as to form a printed support F / D / S, the decoration D being sandwiched between said film D and said support S, c) shaping said printed support F / D / S, so as to obtain a printed packaging.
- the invention relates more specifically to metal packaging obtained, according to the state of the art, by printing a metal strip and then shaping this strip, typically by stamping.
- the invention as is clearly seen in the figures, completely modifies the manufacture of packaging, in particular metallic, printed. Indeed, on the one hand, the invention makes it possible to avoid the passage from the support material in strip to the support material in format. On the other hand, the invention avoids the direct printing of the metallic support, which has two advantageous consequences: * the printing of metallic support is costly in energy since at each printing pass, it is necessary to bring to high temperature the metal support itself. * moreover, the storage of printed metallic support is much more expensive in terms of capital costs than the storage of printed film.
- the invention constitutes, if not a revolution, at least a radical change which is particularly advantageous in terms of production costs.
- FIG. 1 diagrams the production of metallic packaging printed according to the state of the art: a metal strip S ⁇ (strip support in the form of coils) is transformed into support in Sp format,
- the stack of support in Sp format is then printed to give a stack of printed formats Sp / D,
- FIG. 2 diagrams the production of metallic or non-metallic printed packaging according to the invention:
- This reel of printed film D / F is heat-sealed to a strip of support material S ⁇ to give a reel of printed support material S ⁇ / D / F.
- FIG. 3 shows schematically the method according to the invention and illustrates the position of the decoration D, between the film F and the support S.
- said support S and said film F are assembled by choosing, as decoration ink D, a thermoadhesive ink to said support S.
- the support S can be a strip or a metal sheet with a thickness greater than 50 ⁇ m, which can be made of aluminum or aluminum alloy, or steel.
- the support S can also be a strip or a sheet of thermoplastic material, which can be chosen from PE,
- the support material S is used in strip or reel.
- the film F is made of polyolefin chosen from PE, PP, PE / PP copolymers, or PET, depending on the mechanical and thermal stresses to which it is subjected.
- thermoadhesive to said support S is chosen so that the thermoadhesive to said support takes place at a temperature at least 20 ⁇ C above the drying temperature of the ink on said film F.
- said ink is an ink comprising a first resin ensuring the drying of the ink and the possibility of obtaining an F / D printed film on a reel, and a second resin at least partially ensuring the assembly function of the film printed F / D on said support S by heat sealing at a temperature higher than that of drying of the ink on said film.
- this ink can be a liquid ink with solvents for gravure printing, said first resin being based on cellulose resins.
- cellulosic resins are preferably chosen from nitrocellulose, cellulose acetopropionate, cellulose acetobutyrate, ethylcellulose.
- said ink is a UV-drying ink, said first resin comprising oligomers crosslinkable under UV radiation.
- said second resin comprises carboxylic acid functions allowing the adhesion of said ink on said support S.
- said second resin is a copolymer or a terpolymer comprising carboxylic groups.
- said second resin can be confused with said first resin insofar as the latter can allow on the one hand, the drying of the ink deposited on the film F, at relatively low temperature, mainly by elimination of solvent, on the other hand, at higher temperature, the heat sealing of the printed film F / D on the support S.
- said ink also comprises a crosslinking agent for said first and / or second resin, so that said ink is sterilizable.
- a preformed reverse decoration was produced on PP film 30 ⁇ m thick, by gravure printing.
- solvent inks comprising: * as solvent, ethyl acetate
- This material was stamped to give boxes. No particular problem was noted during the manufacture of these boxes or during the packaging and sterilization which followed.
- the advantage of the invention is essentially economic. It has been estimated, in the case of the manufacture of printed metallic packaging, that the method according to the invention makes it possible to reduce the manufacturing costs by 5 to 10% depending in particular on the necessary level of stocks of intermediate products. Indeed, in the metal packaging and canning industry in particular, the time can be very short between an order for the boxes and their delivery, given the fact that the quantities of food to be packaged (vegetables, fish, etc.) depends a lot on random factors, and in particular on meteorology.
- the invention therefore makes it possible to store reels of printed film instead of storing stacks of printed metal format, which makes it possible to reduce delivery times, without increasing the stock of work in progress in metal formats, stock whose financing is expensive.
