100,000+ BPH<\/strong><\/td>\r\n High-speed industrial production<\/td>\r\n <\/tr>\r\n <\/tbody>\r\n<\/table>\r\n\r\nLabeling Technologies<\/h2>\r\n\r\nSelf-Adhesive Labeling Machines<\/h3>\r\n\r\nSelf-adhesive labelers<\/strong> represent the most common and versatile technology, suitable for different container types and shapes.<\/p>\r\n\r\nOperating principle:<\/p>\r\n\r\n \r\n - Labels mounted on a reel<\/strong> with special adhesive backing<\/li>\r\n
- Reel installed on a dispensing unit<\/strong><\/li>\r\n
- Labels release at the precise point of bottle passage<\/li>\r\n
- Adhesive separates easily from paper support<\/li>\r\n<\/ul>\r\n\r\n

Cold Glue Labeling Machines<\/h3>\r\n\r\nCold glue labelers<\/strong> use pre-cut labels inserted in dispensers with storage magazines. Glue is taken from a tank and applied directly to labels before container application.<\/p>\r\n\r\nCharacteristics:<\/p>\r\n\r\n \r\n - Economical solution<\/strong> for low to medium volumes<\/li>\r\n
- Suitable for rectangular or square<\/strong> containers<\/li>\r\n
- Works with metal, cardboard, PET, PVC<\/strong> materials<\/li>\r\n<\/ul>\r\n\r\n
Sleeve Labeling Machines<\/h3>\r\n\r\nSleeve labels<\/strong> (shrink or heat-shrink) represent advanced labeling technology increasingly popular in beverage and food industries. These labels narrow around products, adapting to container shape and utilizing the entire surface<\/strong> for marketing and information.<\/p>\r\n\r\nSleeve Types<\/h4>\r\n\r\n\r\n \r\n \r\n | Type<\/th>\r\n | Description<\/th>\r\n | Application<\/th>\r\n <\/tr>\r\n <\/thead>\r\n | \r\n \r\n Stretch Sleeve<\/strong><\/td>\r\n | Elasticized cylindrical tubular film; pre-cut labels detached from lower tab<\/td>\r\n | Cylindrical containers; bulk packaging for product grouping<\/td>\r\n <\/tr>\r\n | \r\n Shrink Sleeve<\/strong><\/td>\r\n | Heat-shrinkable film; shrinks at ~100\u00b0C via steam<\/td>\r\n | Complex shapes; 360\u00b0 decoration; 10-color printing<\/td>\r\n <\/tr>\r\n <\/tbody>\r\n<\/table>\r\n\r\n Sleeve label advantages:<\/p>\r\n\r\n \r\n - No adhesive glue<\/strong> required \u2014 shrinks by heat<\/li>\r\n
