Definitions
- the invention relates to the field of sealing materials, whether it is a sealing strip or precut lids, typically intended for sealing thermoformed plastic jars, typically made of PS, generally containing dairy products such as than yogurts or desserts such as creams.
- a typical sealing material consists of a multilayer structure shown, viewed from the inside to the outside, by a succession of layers of
- NTC - overprint varnish
- inks generally contain coloring matter which tends to migrate, and which, as a result, may find themselves mixed with food products.
- the invention aims to obtain a sealing material which solves the problem of interior marking of traditional sealing materials without significant additional cost.
- the sealing material intended to seal a jar by sealing to package a product, typically a food product, comprises, from the inside to the outside, a layer of heat-transfer varnish VTC, a support layer in thermoplastic material SMT, a metallization layer M, and typically a decoration or an external impression IMP, said layer of thermo-adhesive varnish VTC forming an internal surface of said sealing material and said decoration or said external impression IMP forming an external surface of said material '' sealing, so as to have a structure symbolically represented by VTC / SMT / M / IMP, and is characterized in that a visual contrast means is formed in contact with said layer of VTC fusible varnish, so that, typically after peeling said sealing material when opening said jar for consumption of said food product, an interior pattern is visible, distinguished from a background formed by the rest of said interior surface devoid of said interior pattern.
- This sealing material solves the problems posed. Indeed, on the one hand, it makes it possible to use the metallization layer M as a light-reflecting element or a mirror, the layer of VTC fusible varnish locally comprising an alteration or a modification capable of leading to a visual contrast making it possible to form a message, which can consist of letters, numbers or words and possibly be pictorial.
- this local alteration of the VTC layer is carried out without ink or coloring matter, so that it does not pose any of the migration problems associated with the introduction of a coloring matter in contact with food.
- this sealing material is derived from a standard product and formed according to standard methods, so that its additional manufacturing cost can be considered as marginal.
- said visual contrast means may have a small relative thickness, typically less than 3 ⁇ m, and preferably less than 2 ⁇ m, or even less than 1 ⁇ m, so as to have said sealing material in the form of coils. typically free of deformations. This is of course very advantageous in practice.
- said interior pattern can form an interior printing layer IPi.
- this interior printing layer IPi can be formed by gravure, flexo, offset printing or by screen printing.
- This interior printing layer IPi can also be identified with respect to the exterior printing layer IMP.
- said interior printing layer IPi can be placed on the layer of heat-transfer varnish VTC, so as to have, at said interior pattern, the symbolic structure IPi / VTC / SMT / M / IMP .
- said interior printing layer IPi can be placed under the layer of VTC fusible varnish, so as to have, at said interior pattern, the symbolic structure VTC / IPi / SMT / M / IMP .
- said interior printing layer IPi can adjoin the layer of heat-transfer varnish VTC, so as to have, at said interior pattern, the symbolic structure IPi-VTC / SMT / M / IMP .
- both said interior printing layer IPi and said layer of heat-transfer varnish VTC are deposited in a marked manner, one layer being identified with respect to the other by one of the printing methods already mentioned in connection with said interior printing layer IPi.
- said contrast means can be formed by a difference in opacity or in shine between said interior pattern and said background, the metallization layer reflecting more or less light, said interior surface comprising a shiny part. or transparent and a less shiny or more opaque part.
- said interior pattern typically the IPi layer, may be brighter than said background, the metallization layer reflecting more light at the location of said interior pattern than at the location of said background.
- said interior pattern typically the IPi layer
- said interior pattern being able to be less shiny than said background, the metallization layer reflecting less light at the location of said interior pattern than at the location of said background.
- said less shiny or opaque part can be formed by a varnish, typically a VTC fusible varnish, containing a mineral filler, typically micronized talc at a weight content ranging from 0.5% to 10% in dry matter.
- said less shiny or opaque part can be formed by a varnish, typically a VTC fusible varnish, comprising a dispersed organic material, typically a resin, immiscible in a fusible varnish.
- said less shiny or opaque part can be formed by a varnish, typically a VTC varnish, comprising a material having, at room temperature, a white color due to its crystallinity.
- said interior printing layer IPi can be an external layer comprising a VTC fusible varnish and an adjuvant having a surface tension of that of the VTC fusible varnish of said base, so that said food products preferentially adhere either to said VTC varnish or VTC and are typically repelled by said VTC or VTC varnish.
- said visual contrast means can be formed by locally creating a micro-relief on the surface of the VTC fusible varnish layer, so as to have a smooth and shiny surface for said background and a rough and opaque surface for said pattern. interior, which can be obtained with a cylinder comprising a rough relief pattern, making it possible to locally alter the surface condition, and thus to disturb the light reflected by the layer M forming a mirror.
- said support layer of SMT thermoplastic material can be a PET layer with a thickness ranging from 10 ⁇ m to 15 ⁇ m and typically with a thickness of 12 ⁇ m.
- Said external impression IMP can be formed on a paper support Pa, typically secured to said support layer of thermoplastic material SMT, by means of a layer of adhesive or glue Ad, so as to have, for the upper part or outside of said support layer in SMT thermoplastic material, the symbolic structure SMT / M / Ad / Pa / IMP.
- Said external imprint IMP can be covered with a VSI overprint or varnish, so as to have, for the upper part or external to said support layer in SMT thermoplastic material the symbolic structure SMT / M / Ad / Pa / IMP / VSI.
- the order of layers SMT and M can optionally be reversed, so that the layer M is placed inwardly in contact with the VTC fusible varnish.
- We can thus have the following symbolic structure IPi / VTC / M / SMT / IMP instead of IPi / VTC / SMT / M / IMP, or even IPi / VTC / M / SMT / Ad / Pa / IMP / VSI instead of IPi / VTC / SMT / M / Ad / Pa / IMP / VSI.
- Another object of the invention is formed by a strip sealing material formed by the sealing material according to the invention.
- Another object of the invention is formed by precut lids formed by cutting lids in the lidding material according to the invention or in the lidding material in strips according to the invention.
- Lidding materials were produced in the following manner, from the usual commercial products to form the standard lids, with regard to the VTC fusible varnish, the adhesive layer Ad, and the layer of paper Pa which is a paper. coated at 45 g / m: The following multilayer materials were manufactured in a single pass on a gravure printing, varnishing and adhesive application line: - IPi / VTC / SMT / M / Ad / Pa,
- a VTC heat-sealing varnish comprising a mixture of a heat-sealing varnish with a micronized talc filler. Tests carried out with 0.5% by dry weight, at 1%, 2%, 3% 4% and 5% of micronized talc.
- VTC heat-sealing varnishes have been deposited by gravure printing, directly on VTC fusible varnish deposited with a roller, under this VTC varnish, or side by side, and in the latter case, both VTC and VTC varnishes have been deposited by gravure printing or by screen printing. .
- Resins have also been used which exhibit a typically white color at room temperature due to their typically low crystallinity.
- the invention has great advantages. Indeed, in addition to offering a wide variety of modalities, it allows forming on the inner side of the sealing material, and visible only once the cover has been peeled to open the jar, any type of message, whether in the form of words, letters, numbers, or in the form of images or symbolic representations, so as to have the basis of a game or a lottery.
- the invention is implemented using only traditional means in the trade of manufacturing the lids and lidding materials.
- it makes it possible for example to dispense with expensive equipment which uses a laser beam to modify the surface of a film.
- this surface is generally deeply altered, in particular with the formation of hollows and excess thicknesses, which can be troublesome in the case of films on reels.
