The core operation of a hot melt adhesive labeling machine can be divided into the following steps:
- Adhesive Heating and Supply
Using a dedicated hot melt adhesive device, the adhesive is heated to an appropriate working temperature (usually between 160°C to 180°C). The heated adhesive is then transferred through the adhesive supply tube to the adhesive dispenser, preparing for label adhesion. - Label Cutting
Labels are automatically extracted from the label roll and cut into pre-set sizes using a rotating knife. A sensor ensures the accuracy of each cut by the rotating knife. - Adhesive Coating
After cutting, the labels are fed into the adhesive coating zone via the labeling mechanism. A thin layer of hot melt adhesive is evenly applied to the surface of the label or the designated area of the container. - Label Attachment
The labeled adhesive is applied, and the label is precisely attached to the container (e.g., bottle or can) through the high-speed rotation of the turntable. Finally, the labeled container is further fixed by a pressure roller to ensure stability.
Advantages of Hot Melt Adhesive Labeling Machines
- High Efficiency and Stability
The rapid solidification of hot melt adhesive ensures that labels are firmly fixed to containers in a short amount of time, making it suitable for high-speed production lines. The equipment operates stably, reducing downtime caused by labeling issues. - Cost-Effective
Hot melt adhesive uses less material and is relatively inexpensive compared to traditional water-based or solvent-based adhesives, making it more economical. It is ideal for long-term mass production. - Excellent Adhesion
Hot melt adhesive can adhere to various container surfaces such as plastic, glass, and metal, ensuring the labels are firmly attached and not easily peeled off. The appearance of the label is smooth and beautiful, enhancing the packaging quality of the product. - Environmental Friendly and Easy to Clean
Hot melt adhesive is a solvent-free adhesive, and no volatile organic compounds (VOCs) are produced during use, making it environmentally friendly. The equipment is easy to clean, reducing maintenance time and costs. - Wide Range of Applications
Suitable for various container shapes and materials, such as beverage bottles, food cans, and daily-use products. It can handle both round and square bottles, offering high flexibility in applications.
