Depth Analysis of Beer Glass Bottle Labeling Quality

Most beer companies today use glass beer bottles, and glass beer bottles have several types, such as watermarking and paper printing.

In the packaging of beer products, not only the unique appearance of the carton is required, but also the intrinsic beer trademark must be exquisite. At the same time, trademarks must be generous and have a unique charm.

In the beer production process, the quality of the beer bottle labeling will not only affect the beer production efficiency, but also affect the quality of the labeling. If labeling is not effective, it will directly lead to the phenomenon of breaking marks, wrinkles, dropping marks, and tilting of the target during the transportation process, which will seriously affect the aesthetic appearance of the mark and visually influence the consumers' desire to purchase beer products.

This article systematically studies the problems that may occur during the labeling process of bottled beer and the factors that affect the quality of the labeling, for reference by peers.

The following aspects are closely related to the quality of the labeling: the quality of the trademark itself (including the use of circle labels, back labels, etc.); the quality of the labeling machine itself; the quality of the labeling glue and its subsequent packaging, beauty, storage, and transportation Related factors.

I. The factors of the trademark

The types of paper beer brands include aluminum foil labels, copper paper labels, wet strength paper labels, and laser paper labels. In general, the paper board has a higher water absorption rate and the aluminized paper has a lower water absorption rate.

Under normal circumstances, beer companies will control the brand's water absorption rate to 8%-18%. This requires that the beer branded paper should have moderate water absorption and a small trademark expansion coefficient. Such trademarks can avoid wrinkling and labeling during the labeling process.

In addition, the selection of a suitable label for beer bottles and a certain ambient temperature is an important aspect of beer packaging quality.

When choosing the labeling paper, we can use several different labeling papers to carry out the experiment analysis in the process of labeling the specific labeling glue: Several different trademark article sources: beer of cnwinenews.com labeling paper Store in a relatively low temperature environment to see which mark is easily peeled off to study the water resistance of the mark.

Since many retail stores temporarily store beer in a refrigerator or a freezer during beer storage, it is easy for the brand to excessively absorb water and fall off. The above experiment is also a preventive measure that mimics external factors.

Good label paper procurement requirements: The surface of the label paper is smooth, the printing performance is good, the trademark glue is not transparent, the alkali resistance is good, the breaking strength is high, and the bending rigidity is small, ie the toughness of the label paper should not be too great, the wet state pulls off The strength should be large enough, not less than 30% of the dry state. Smooth edge should not have flash, high dimensional accuracy, allowable error of ± 0.25mm, poor water absorption, can cause the label edge to tilt.

Label storage environment: relative humidity 60% -70%, temperature 20 °C -25 °C, in order to ensure the flatness of the label.

Check whether the trademark's moisture is qualified, whether the thickness of the trademark paper is reasonable, and whether the fiber direction of the trademark paper is perpendicular to the bottle axis direction.

1.Experimental analysis of the shedding effect of trademarks using different water temperatures (5°C-30°C) (Table 1)

From the evaluation results shown in Table 1, it can be seen that as the temperature of the water bath slowly rises, the water absorption of the brand is also gradually increased, that is, the degree of detachment around the trademark is accelerated, and the water resistance gradually decreases.

2. Using the same water temperature (25°C) to evaluate the shedding effect of different brands (Figure 1)

From the relative index analysis of Fig. 1, the water resistance description results for different brands at the same temperature show that the water resistance of each type of trademark label paper is somewhat different. The figure shows that each type of brand name label paper has relatively good water resistance.

3. Use a specific experiment to perform a corresponding test analysis on the selected trademark (Table 2)
