Beverage label paper is a type of paper specifically designed for labeling bottles, cans, and other beverage containers. It is typically made from a combination of pulp and synthetic materials to ensure durability, water resistance, and adherence to the container surface. Beverage label paper is often coated with a special finish to enhance print quality and prevent smudging or fading of the label design. It can be customized with various printing techniques, such as flexography or digital printing, to create eye-catching labels for different types of beverages, including water, soda, juice, beer, and wine.

When it comes to beer and beverage labels, there are certain requirements that must be met. One of the most important factors is that the labels used on return bottles must be removable before reusing the bottle. This is crucial because these bottles are washed in washing machines using strongly caustic detergents. In order to ensure the labels do not clog the washing machine, they must remain intact so that they can be easily removed by a coarse grid.

To meet these requirements, the body paper as well as the coating of the label must have good wet and caustic strength. This is achieved by using wet-strength resins, which help the labels withstand the harsh washing process without deteriorating.

Another important consideration for beer and beverage labels is the efficiency of bottling lines. These high-efficiency lines set big demands on the labels, as the feeding must be smooth and secure. This requires a rough back side of the label to ensure proper adhesion to the bottle during and after labeling. Additionally, the label must have the right degree of absorbency, stiffness, and dimensional stability to prevent it from peeling off or becoming damaged. This is especially important considering the cold bottles condensing moisture from the environment, which can further impact the label’s integrity.

The paper used for beer and beverage labels is typically made of a mixture of short and long fiber bleached chemical pulp. This combination helps achieve a basis weight of about 70-75 g/m2, which is suitable for label production. Coating is mostly done by blade, and the paper is supercalendered to enhance its smoothness and overall quality.

It is worth noting that there are also other varieties of beer and beverage labels that are partially made with mechanical pulp. This variation in materials allows for different characteristics and performance, depending on the specific needs and requirements of the product and brand.

In conclusion, the production of beer and beverage labels involves careful consideration of various factors. From ensuring the labels can be easily removed from the bottles during the washing process to meeting the demands of high-efficiency bottling lines, the paper and coating used must possess the necessary wet and caustic strength. By utilizing a mixture of short and long fiber bleached chemical pulp, along with appropriate coating techniques, manufacturers are able to produce labels that meet the specific needs of the beer and beverage industry.
