Definitions
- the present invention relates to a solvent-based two-component adhesive composition of the polyurethane type.
- the invention also relates to a multilayer (or complex) structure, usable in particular in the field of flexible packaging, which comprises at least two layers of material bonded together by a layer of the crosslinked composition according to the invention.
- the present invention also relates to the use of said multilayer structure for the preparation of flexible packaging for agri-food products.
- Flexible (or flexible) packaging intended, in particular, for the packaging of agrifood products generally consist of several thin layers (in the form of sheets or films) whose thickness is between 5 and 150 ⁇ m and which are made up of different materials such as paper, a metal (for example aluminum) or else by thermoplastic polymers.
- the corresponding complex (or multilayer) film makes it possible to combine the properties of the different individual layers of material (also called “supports") and to thus offer the consumer a set of characteristics adapted to the final flexible packaging such as, for example, its visual appearance (in particular that of the printed elements presenting the information concerning the packaged product and intended for the consumer, or even its transparency), a barrier effect to light or to atmospheric humidity or to gases, in particular to oxygen, or alternatively an appropriate thermal resistance.
- the various layers of materials that make up the multilayer film are typically combined or assembled by lamination, during industrial lamination (or even "lamination") processes. These methods use adhesives (or glues) and equipment (or machines) which are designed for this purpose and which operate continuously with generally very high line speeds, of the order of several hundred meters per minute.
- the multilayer film thus obtained is often itself referred to by the term "laminate”.
- These lamination processes firstly comprise a step of coating the adhesive on a first film of material, which consists of depositing a continuous layer of glue and of controlled thickness generally less than 10 ⁇ m, corresponding to a quantity of adhesive (or weight) generally not exceeding 10 g/m 2 .
- This coating step is followed by a step of laminating a second film of material, identical to or different from the first, consisting of the application under pressure of this second film on the first film covered with the layer of adhesive.
- Complex films are thus finally obtained in very large widths and are generally packaged by winding, in the form of large reels from 1 m to 1.50 m in diameter having, like the film they store, up to 2 m wide. .
- These large coils can be stored and transported, with a view to their use either directly by the food industry, with a view to packaging their product, or by processors (or complexers, also referred to by the English term “converters” ).
- the film is cut to reduce its width, and shaped to manufacture sachets, themselves intended for the packaging of a product, for example an agri-food product.
- Two-component solvent-based polyurethane laminating adhesives are widely used as glue for the manufacture of multilayer systems intended for the field of flexible packaging.
- the implementation of said solvent-based adhesives in the complexing process necessitates a step of evaporation of the organic solvent. This step is carried out before the laminating step by passing through an oven the first film covered with adhesive following the coating step.
- Two-component polyurethane type laminating adhesives with solvent are supplied to the laminator in the form of 2 compositions (or components):
- -NCO component comprising chemical entities bearing isocyanate -NCO end groups
- the mixture of these 2 components can be carried out at room temperature by the operator of the complexing machine before starting it up, which allows it to operate correctly, thanks to an appropriate viscosity.
- the isocyanate groups of the -NCO component react with the hydroxyl groups of the component -OH, according to a so-called crosslinking reaction, to form a polyurethane which is in the form of a three-dimensional network with urethane groups, ensuring the cohesion of the adhesive joint between the 2 thin laminated layers.
- adhesive compositions with good chemical resistance are known to contain toxic raw materials or which should soon be banned for regulatory reasons, despite their positive impacts on adhesion performance. This is particularly the case with epoxies (resins) or bisphenol-A.
- polyurethane-based adhesive compositions generally have the disadvantage of using a majority NCO-terminated NCO component comprising significant residual contents of diisocyanate monomers originating from the synthesis reaction of the NCO-terminated polyurethane prepolymer.
- These residual quantities of low molecular mass (so-called free) diisocyanate monomers are likely to migrate through the multilayer film, after the implementation of the two-component adhesive, and therefore through the final flexible packaging.
- said compounds are capable of forming by hydrolysis, in contact with water or moisture present in particular in packaged foods, primary aromatic amines (often designated by the English terms Primary Aromatic Amines or PAA), which are considered as very harmful to human health and the environment.
