The technical field to which the invention relates

The present invention relates to a method of continuous printing water-soluble film during production of water-soluble package detergent.

The level of equipment

Print on water soluble film is known in the art. International application № WO 2007/034471 refers to printed film for water-soluble detergent containing film based and at least one output printed on it and (or) on the aforementioned film, and the film contains water-soluble cleanser, adapted for effective cleaning at wash different human bodies and things. US patent # 5666785 refers to print directly to a water-soluble film. Specifically, it relates to a method and apparatus for printing text and graphics directly on the water-soluble film when the film is in the process of formation in water-soluble container packing machine. The printing process is triggered when the packaging machine temporarily stops moving film during cycle of forming, filling and sealing, which is water soluble container. The application for the patent Japan # 55-034966 refers to print on fruit undistorted prints without damaging these fruits. This method includes printing water-soluble film, gluing of this film on fruit with glue, and then removing the film dissolution.

Production of water-soluble packets known in the art. International application № WO 02/40351 refers to the process of production of water-soluble packets. European patent no 1504994 reveals the process of the production of water-soluble multicell package the application for the patent, US no 2008/0041020 refers to water-soluble Pb package for washing dishes.

Offline printing is used for the labeling of the packaging material and is achieved by printing on the packaging material in a separate process before packing material is placed in a packaging machine. Usually this stand-alone printing process requires that the rolls of packaging material were unwound, printed, and then heated to dry. Next, packaging material again wound into rolls and stored prior to submission to the actual packaging process.

Water-soluble detergent packages are prepared from the Autonomous printed soluble film. This process revealed in the jointly considered patents of USA №№12/270534 and 12/270547.

Offline printing uses redundant parts of the process and slows down the process of packaging production. Further, since the printing process is separated from the actual process of packaging, equipment removed from one another, and therefore all work requires a large area. Further, excessive manipulation of water-soluble film when unwinding and reverse winding film can damage the integrity and durability of the very water soluble film. Loss of integrity and strength of will adversely affect the quality of the final product. Excessive manipulation can also lead to increased levels of waste due to the start and end time of each process. The costs associated with the handling of these wastes should be significant. Another disadvantage of the Autonomous printing is the storage of printed material that requires additional space for storage. Offline printing also creates the risk of printing over design.

There is a need in the way in which water-soluble film can continuously to print, and then immediately use in the process of manufacturing of packages.

Disclosure of the invention

Method of production of water-soluble detergent package with printed on it the graphics containing feed water soluble film through:

a) at least one section of flexographic printing; and then

b) a section for the production of water-soluble detergent packages; characterized by the fact that water-soluble film is formed into packets immediately after printing mentioned water soluble film.

Short description of the drawing

Figure 1 shows a section of flexographic printing in production lines with section production of water-soluble packets.

Detailed description of the invention

Figure 1 illustrates the present invention. However, the above illustration is given only as an example and is not meant to be restrictive.

The method of the present invention includes a section flexographic printing. Flexographic printing is a direct way rotary printing that uses flexible printing plates, usually made of rubber or plastic. These plates with a slightly raised area of the image, rotate the cylinder, forming a cushion for a graphic image, which transfers the image on a substrate.

The phrase «in production lines» refers to that section of flexographic printing and the production of water-soluble packets placed next to one another. Unlike stand-alone printing imprinted water soluble film is not stored before use in the production of packages.

The term «media» refers paints and dyes, as well as covering the printing varnishes, gels, liquids, powders, perfumes microcapsules and other functional materials.

Section flexographic printing ignitable tray (2) print material, intermediate roller podocyturia for printing, called anilox roller (3), roller (4) for the graphic image and pressing roller (5).

In the process of printing with a single print media requires one flexographic section. In the printing process with many printed materials, water soluble film passed through many sections of flexographic printing. The print media from different flexographic sections can be applied to one and the same water soluble film. Printing thus enables the manufacturer to produce multi-color images or parts of images from a variety of print materials, patterns and effects. In the process of printing with different materials for printing multiple sessions flexographic printing can be placed in a production line, one after the other or multiple sessions flexographic printing can accommodate around one large Central impression cylinder to produce color images or parts of images.

Tray print media and print media

The tray (2) of print media contains the stock of print media. In a preferred embodiment, the stock of print media is a continuously circulating material for printing, thereby controlled viscosity of the material to be printed. If viscosity of the print media is too high, the print media may be allowed to dry on the surface of the platen for a graphic image. This has a negative impact on the quality of printing, because the media will not be fully transferred to the surface of the water soluble film in the printing process. Print media can be like water for consistency with low viscosity, or, alternatively, it may have a pasty consistency and high viscosity. However, in order to ensure high quality printing, it is important in the process of printing to maintain the viscosity of the material for printing preferably constant. Viscosity of print media can be manipulated by adding water or another solvent. In a preferred embodiment, the print media has viscosity from 300 JV (CP) to 10000 JV, preferably from 80 SP-8000 JV and even more preferably from 1000 SP 5000 SP.

The appropriate print media for that invention suitable for printing water-soluble film and that film was desirable properties for dissolution and the coefficient of opacity. The print media must also ensure the desired level of dispersion in water. The print media for a given preferably represents the beauty of the colouring substances, covering printing varnish, gel, powder or nitrogen. Preferably, the print media is paint. The most preferred material for printing is a water-soluble paint.

When painting color print media preferably choose from white, red, blue, yellow, green, pink, purple, orange, black, grey, and their mixtures. In one embodiment, when the selected print media has a color other than white, covering seal lacquer is also preferable to apply on surface water soluble film on top of the paint. The most preferred paint is white.

The most preferable water soluble paints are paints, known under the trade name SunChemical Aquadestruct sold by SunChemical, new Jersey, USA, and paint relevant characteristics. Other suitable paints known under the trade names Aqua Poly Super Opaque White QW000046, Film III Opaque White FR EC007094, Stable Flex ES Opaque White SFX02700, Plus 0700 Pro Plus Opaque White Plus0700, all of which are sold by the company Environmental Inks, and Opta Film OPQ White W0L009656 sold by the company Water Ink Technologies Incorporated, and paint relevant characteristics.

Covering printing varnish

The present invention may contain additional section flexo printing water-soluble covering seal lacquer on a pre-printed material, and optionally on a water-soluble film. The advantage of covering printing varnish is that he does printed material grapestone. The additional purpose of covering printing varnish water-soluble film is to improve stability at storage, in particular, in the environment with high humidity. Next, cover the printing varnishes can also improve tactile quality printed films.

Suitable covering printing paints for printing on a water-soluble film are those which give the possibility of resultant film has the desired properties for dissolution and the coefficient of opacity. Himself a covering seal lacquer must also provide the desired level of dispersion in water. Preferred covering printing paint is water-soluble. Technically covering printing varnish is a pigment ink without the component that contains isopropyl alcohol, water and preferred polymers. Preferred polymers provide the desired technical characteristics and attach a covering seal lacquer structure. The most preferred covering seal lacquer known under the trade name OPV Aquadestruct sold by SunChemical, new Jersey, USA, and covering printing varnishes relevant characteristics. The owner preferred covering printing varnish is SunChemical.

Covering seal lacquer can be applied to the surface of the water-soluble film. In one preferred embodiment, the print media is located between water film covering the printing varnish.

Functional material

The print media may contain functional material subject to printing water-soluble film. This functional material may be in solid, gel or liquid, or solid suspended in the gel or liquid. Functional material preferably selected from the group consisting of bleach, bleaching activators, for flavouring microcapsules, substances with pearl effect, coloring substances and bleach, including toning pigments and fotouvelichitel, as described in the jointly considered by the European patent application # 08158232.2. The latter requires a covering seal lacquer provided adhesion to the film and facilitating the extraction to a better functioning in the water. The functional purpose of these materials is to improve the cleansing effect of detergent or providing additional psychological or visual effect.

The level of dispersion

The level of dispersion, as used here is the scale used for the ranking of conduct for the print media after water soluble film, on which it is printed, is dissolved.

A 1 degree on the level of dispersion corresponds to the print media, which fully dissipated in the water during the method described below, testing dissolution. The level 2 corresponds to the print media, which partly dispersed in water, and the particles of small size (less than or equal to 1 mm) are present in the water during testing dissolution. Level 3 corresponds to the print media, which scatters minimum, resulting in a larger particles (more than 1 mm) film remain in the water during testing dissolution.

Preferably the level of dispersion of print material on this Annex must be less than 2. More preferably, the level of dispersion of print material on this invention was 1.

The way of testing dissolution

For the following testing method dissolve the water soluble film is aged 24 hours at 21 degrees Celsius (+1.5 degrees C) and 50% relative humidity (+1.5% relative humidity), and it is open without coating or other protection from temperature and humidity.

Cut three copies of sample water-soluble films by $ 3.8 cm x 3.2 see Hold each instance in a separate 35 mm wet holder slides. Fill suitable laboratory glass of 500 ml of distilled water. To measure the water temperature with a thermometer and, if necessary, to heat or cool the water to keep a constant temperature of -20 C. Mark the height of the water column. To place a beaker on a magnetic stirrer; add to a beaker magnetic stick to stir, turn on the mixer and adjust the speed mixing until there is a whirlpool that is approximately one-fifth of the height of the water column. To mark the height of the maelstrom.

To fix 35 mm wet clip to a slide in the clip type «crocodile» tripod holder slides so that the long end of the holder slide is parallel to the surface of the water. The depth regulator tripod must be installed so that when dipping the end of the clip was 0.6 cm below the water surface. One of the short sides of the holder slides should be next to the wall of the laboratory glass, and the other is located directly above the middle of the stirrer, so the film's surface perpendicular to the flow of water.

The rate of dissolution of = Time of dissolution printed films / Time of dissolution neotectonic film.

The rate of dissolution for the printed soluble film of the present invention must be less than 1.5, preferably less than 1.3.

The opacity coefficient

The coefficient of transparency as used here, is an indicator relating to the adhesion of the print media for surface water soluble film. Abrasion resistance is desirable, and sometimes critical property of the print media. Damage from abrasion can occur during transport, storage, handling and final use. The result is a significant deterioration in the external appearance and readability of printed figure. The amount of damage from abrasion for printed substrate depends on the conditions of transport, possible temperature and humidity, time, and many other variables. This method of testing gives a method of comparing the relative wear resistance of the printed materials in the laboratory. This method of testing can be used to evaluate the relative wear resistance of the printed inks, coatings, laminates and substrates.

Opacity is a measure of the ability of printed material to obscure what is in the background. The opacity value is by dividing the coefficient of reflection on a black background (PTS) (RB) for material on reflection coefficient obtained for the same material on a white background (OB) (RW). This is called a relative way of contrast. Opacity is measured reflective spectrophotometer Hunter Labscan HEH, Hunter D25DP9000 supplied HunterLab, or equivalent.

Opacity = PTS/ABOUT.

The present invention, the opacity of the printed film is calculated by dividing the coefficient of reflection printed film after testing of the surface resistance (FDI) (Suthertland USD test, SRt) on reflection coefficient obtained for the same material to the testing of the surface resistance. Testing method coatings, wear described in detail below.

Opacity = (PTS printed film after FDI / ABOUT printed film after FDI) / (PTS printed film to FDI / ABOUT printed film to FDI).

The coefficient of transparency in the present invention preferably more than 0.38, preferably more than 0.50, but it is most preferable more than 0.85.
