| Features | Self-adhesive labeling machine | Hot Melt Adhesive Labeling Machine | Sleeve Labeling Machine |
| Core Principle | Peel and lamination | Melting and applying | Sleeve and Shrink |
| Label Format | Pre-adhesive label rolls with backing paper | Single sheet of adhesive-free label paper | Prefabricated plastic film sleeves in tubular form |
| Adhesion Method | Pre-coated pressure-sensitive adhesive | On-site heating and melting of the same hot melt adhesive | No additional glue required, relying on the film’s elasticity or heat shrinkage |
| Workflow | 1. Label delivery 2. Peel backing paper off 3. Sensor positioning 4. Apply label to product | 1. Heat and melt the adhesive. 2. Apply the adhesive to the container or label. 3. Attach the label and press firmly. | 1. Open the sleeve. 2. Insert the container through the sleeve. 3. (Shrink sleeve only) Pass the label through a heat tunnel to secure it to the container. |
| Visual Analogy | Just like applying a sticker | Like using glue sticks for stickers | Just like wearing a T-shirt or heat shrink tubing. |
| Main Benefits | Clean, precise, flexible, and capable of printing variable data | Extremely strong, fast, and cost-effective (for large quantities) | 360° packaging, tamper-evident, adaptable to uniquely shaped containers, and a gorgeous appearance. |
| Typical Applications | Food packaging, cosmetic bottles, medicine boxes, electronics | Beer bottles, glass jars, beverage cans, heavy chemical containers | Beverage bottles, mineral water bottles, condiment bottles, cooking oil bottles, and medicine bottles. |
