New development of beverage can labeling technology

The development technology of beverage packaging labels is on the rise. In addition to marking the brand, composition and shelf life of products, the developer is working hard to develop a product package that is low in cost, strong in impact resistance and attractive in appearance. With the development of new technologies for shrink packaging systems and the emergence of shrink labels and adhesives, roll-feed shrink label bonding technology provides processors with a low-cost, low-consumption, and high-resolution labeling process.
B&H Labeling Systems continues to develop a new generation of labeling systems. Its BH8000 series is especially targeted at label packaging customers who need high speed, reliability and high efficiency. Coles from the United States caters to the appearance and circular edge requirements of its PubBarrelTM brand beer cans. B&H specifically offers the BH8000S labeling system and the BH700 EnduraTM shrink label system. Through the mutual cooperation of the two sets of units, the attached label not only reveals the barrel-type design of the beer can, but also produces a smooth, highly transparent and impact-resistant beer can label. In addition, the use of shrink labels can provide eye-catching and high-resolution label graphics, thereby increasing shelf appeal.
Process Technology The BH8000S labeling system is based on an axial conveyor and provides a durable, low maintenance and high speed labeling process. The unit can preset different label size programs according to different packages to simplify the replacement of components or mechanical adjustment processes; when replacing labels, only the label roll can be replaced, which is simple and quick. Manufacturers can continue to label, eliminating the time spent on the label for the conversion of cans. With the new quick change function, it takes only 15 to 20 minutes for various container sizes and labels to be replaced.
The inlet of the BH8000S labeler is separated by a screw and a star wheel to ensure accurate control and positioning of the container in the vacuum chamber. In order to ensure the accurate labeling of the label, the unit is equipped with a company's patented computerized version system to verify the position of the label. The computerized version system utilizes a photoeye sensor to sense the length of the label and automatically adjust the labeling process so as to ensure that each label of the packaging can be accurately cut to achieve the best matching effect. After the cans leave the star-shaped positioning unit, the labels and adhesives are accurately and firmly attached to the cans under the cooling of the air. In order to ensure the accurate positioning of the label, the unit is also equipped with an ultrasonic base material tracking system that automatically controls the vertical movement of the label base material and monitors the height variation of the label. Thus, the labeling system can greatly reduce misalignment and shift misalignment to achieve the highest standards for labeling.
In order to meet the needs of complex label shapes and different shrinkage characteristics, the unit can be equipped with an additional 7 to 8 bar electronic heat guns on the export conveyor belt for secure labeling. Because each rod heat gun is controlled by an accurate electronic temperature controller, it can independently target the label to heat firmly, providing an ideal solution for labels with different shapes and shrinkage characteristics. Specifically, the shrinkage of the label is initiated by heating the center of the label and then heated by a number of heat guns to the bottom of the label until the top of the label is finally heat-sealed. The entire process takes about 2 to 3 seconds. With superior labeling and alignment monitoring packaging technology, the unit's labeling speed is up to 700/min.
New Technology Advantages The roll-feed shrink label bonding technology enables instant label bonding for packaging cans, so there is no need to stock a large number of pre-printed cans, thereby reducing handling costs and storage space in the warehouse. 500,000 labels only require 121 cubic feet of warehouse space, while the same number of preprinted tanks require 16,000 cubic feet of storage space. Furthermore, due to the shortened production process, it is possible to quickly label promotional products, test-market products, or market-standard products while also ensuring a low production price. The roll-feed shrink label bonding technology has a short production process and is affordable, especially for beverage companies, specialty foods and small breweries.
The latest and improved "wireless bonding system" technology can effectively eliminate wrinkles on the trailing edge of the label. The system achieves the smooth surface requirements of PubBarrelTM packaging cans. The development of a new process replaces the previous expensive shrink sleeve label bonding technology or pressure sensitive label adhesive technology. In addition, the unit simply converts the rubberizing wheel to fit various size containers, simplifying the conversion process and increasing production flexibility.
The development of shrink labels With the continuous development of packaging labeling systems, shrink labels and adhesives, price, speed, and materials must all meet economic benefits. At the same time, providing vivid and high-resolution label graphics can lead the trend and increase profits. The roll-feed shrink label bonding technology not only shortens the production process, but also realizes an economically viable instant packaging process, offering manufacturers the choice of diversity and flexibility.
