Description

PROCESS FOR CLEANING AND ELIMINATING LABELS FOR BOTTLES FIELD OF THE INVENTION The present invention relates to a process for cleaning bottles. In more detail, the present invention relates to an improved method for cleaning bottles comprising the removal of bottle labels in a bottle cleaning plant.

BACKGROUND OF THE INVENTION Many beverages sold outside the United States are found in reusable glass bottles. Through the current calculations, annual world production constitutes up to five billion reusable glass bottles.

In known processes, returnable beverage bottles are cleaned in bottle cleaning machines using additives containing sodium hydroxide which is heated to at least 85 ° C. The hot caustic cleaning of reusable glass, ceramic and plastic bottles at temperatures of at least 85 ° C is related to an increased energy consumption.

Many of the reusable glass bottles have labels that are adhered by an adhesive. These labels need to be removed in the cleaning process in Ref. 239492 a bottle cleaning plant. In addition, waste such as dirt, mold, dead yeast cells and the like need to be removed during the cleaning process of a bottle cleaning plant.

The reuse of a glass bottle requires that the bottle remain aesthetically pleasing for the duration of the life cycle. When the bottles themselves appear "washed" and stained, they are no longer aesthetically pleasing, forcing the bottles to be disposed of before the end of their useful lives. This lack of durability is understandable based on the effect on bottle washing processes with hot alkaline material. The cleaners used in hot bottle washing processes at temperatures of at least 85 ° C are designed to be aggressive with the stains but also attack the bottle causing deterioration and a decrease in the useful life of the bottle. The deterioration of the bottle is not desirable because it has a negative impact on the image of the brand, on the affinity of the consumer and on the quality of the beverage container.

In this way, there still remains the need for a bottle washing process that minimizes energy consumption, the attack on the appearance of the glass bottle but still provides an adequate removal of dirt.

SUMMARY OF THE INVENTION The object of the present invention is to provide a cleaning process that minimizes the energy consumption for glass, ceramic, metal and / or plastic articles such as bottles, preferably in a bottle cleaning plant and that still provides a proper dirt removal and excellent label removal properties.

EXAMPLE The - additive EXAMPLE E2 - liquid cleaning additive without surfactant EXAMPLE E3 - non-defoaming liquid cleaning additive EXAMPLE E5 - only sequestrant Label removal test Background: This test method has been developed to evaluate the performance of label removal of different caustic additive substances for bottle washing. The label removal test is a measure for the cleaning efficiency of an additive. It can be applied to polyethylene terephthalate (PET) and for glass bottles. Equipment : 700 ml mineral water glass bottles with a flat outer surface to which a standard Mifare paper label has been attached with a Casein ST 50 KF adhesive Uncoated glass plates of 19 cm x 10 cm or glass bottles of 330 ml of uncoated glass analytical balance capable of weighing up to 0.0001 Casein ST 50 KF adhesive available from the company Tuermerleim GmbH in Lud igshafen / Rhein, Germany (glass plates) Mifare standard paper label with a label size: 85.60 +/- 0.12 mm x 53.98 +/- 0.05 mm, total thickness: 0.30 +/- 0.03 mm and a weight of: 0.20 g +/- 0.05 g roll coater / manual coater double wall container with an internal volume of 5000 ml Process : Label removal device for glass plates: The label removal device consists of an oscillating motor (windshield wiper motor obtained from an "Opel Record" vehicle) wherein a glass plate is fixed in a holding tool in a vertical position for testing. The oscillating motor speed has been adjusted so that it moves forward and backward every second. The test solution is heated in a double walled container. The vessel is connected to a thermostat which regulates the required temperature.

Label removal device for glass bottles of mineral water: 700 ml mineral water glass bottles with a flat outer surface to which a standard Mifare paper label has been attached with Casein ST 50 KF adhesive are processed in a Fontana RE SEN cleaning plant with a capacity of 45,000 bottles per hour. The soaking bath for label removal is filled with the cleaning composition and used in the process of the invention and described below.

Labeling of glass plate: The glass plates are degreased with acetone and dried at room temperature. A label is applied to the glass plates by the manual coater using the Casein ST 50 KF adhesive. The adhesive film must be very thin (100 μp?). The labels are dried for 3 days at room temperature.

Labeling of bottles: The mineral water bottles are degreased with acetone and dried at room temperature. A label is applied to the glass plates with the manual coater using the Casein adhesive, ST 50 KF. The adhesive film must be very thin (100 μp?). The labels are dried for 3 days at room temperature.

Liquid cleaning solution: The various cleaning solutions are obtained by mixing 2000 ml of an alkaline solution of NaOH 2% by weight with 4 ml of liquid cleaning additive of the examples, or 7 ml of the liquid cleaning additive of example El a E5.

After the above, the cleaning solutions as used for removing labels from glass bottles according to Figure 1 are heated in a Soak bath of the Fontana RME SEN equipment at the required temperature of 65 ° C and 80 ° C ( see figure 1) and the cleaning process starts. The time for each glass bottle is measured with respect to the cleaning solution used until the label is completely separated (= label removal time [sec]). For each cleaning solution and temperature, the test is repeated 3 times.

For the glass plate label test, the liquid cleaning composition in the double-walled container is placed at a temperature of 60 ° C (see Figure 2). Subsequently, the marked glass plate is fixed with a fixing tool and the glass plate is inserted into the cleaning solution so that the label is completely immersed in the cleaning solution and the oscillating motor is turned on. The time is measured for each glass plate with respect to the cleaning solution used until the label is completely removed (= label removal time [sec]). For each cleaning solution and temperature, the test is repeated 3 times.

Results: Figure 1 clearly shows that the label removal performance for glass bottles of mineral water of 700 ml with a flat outer surface to which a standard Mifare paper label has been attached with a Casein ST 50 KF adhesive that binds using 7 ml of the example additive The addition to 2000 ml of a caustic solution of 2.0% by weight of NaOH processed at a process temperature of 65 ° C provides the same elimination time compared to 4 ml of the same additive as in the example added to 2000 ml of a 2.0 wt% NaOH caustic solution at a cleaning temperature of 80 ° C. In this way, Figure 1 demonstrates that the process of the present invention provides good cleaning and label removal characteristics at lower temperatures.

Figure 2 shows that the removal of label for glass plates using 7 ml of an additive of example E2, E3, E4 and E5 at 2000 ml of 2.0 wt% NaOH caustic solution at a process temperature of 60 ° C provides an improved tag removal time of between 120 sec to 140 sec. Therefore, Figure 2 shows that the process of the present invention provides good cleaning and label removal characteristics at lower process temperatures.
