Different materials have different thermal stability and melting temperatures. Therefore, the temperature setting should first consider the materials used. For example:
Polyethylene (PE) film: It is usually suitable between 120-180 ° C, depending on the type of PE used and the lamination requirements.
Polypropylene (PP) film: It is generally recommended to set the temperature between 130-200 ° C to ensure good adhesion during the composite process.
Polyvinyl chloride (PVC) film: This material has poor thermal stability, and the recommended temperature for use is usually between 120-150 ° C to avoid material decomposition and discoloration.
2. Composite adhesive
The type of adhesive used directly affects the setting of operating temperature. Different types of adhesives have different curing temperatures. For example:Hot melt adhesive: usually between 160-200 ° C, suitable for quick bonding, but it is necessary to ensure that the ambient temperature does not affect its bonding effect.
Water based adhesive: The temperature during the composite process is generally controlled at 80-120 ° C to ensure the drying speed and bonding performance of the adhesive.
3. Properties of the substrate
The thickness, material, and surface treatment of the substrate can all affect the setting of the operating temperature. For example, the thermal conductivity and temperature tolerance of paper substrates and plastic substrates are different. When composite thicker or rougher surface treated substrates, it may be necessary to increase the temperature accordingly to ensure effective bonding.4. Production efficiency and product quality
In the actual production process, for users who want to achieve high efficiency, they may tend to set higher temperatures to reduce drying time. However, excessively high temperatures may affect the performance, stability, and appearance quality of materials, so it is necessary to find a balance between efficiency and quality.
5. Design and configuration of equipment
The specific design of the laminating equipment, the type of heating system, and the operating mode also have an impact on the temperature setting. Different models of laminating machines may require different temperature settings in their design characteristics, so it is necessary to follow the guidance in the equipment manual during operation.
In some cases, the temperature and humidity of the production environment can also affect the optimal operating temperature of the laminating machine. For example, high humidity environments may slow down the curing speed of adhesives, and it is necessary to increase the temperature appropriately to ensure the drying and bonding performance of the adhesive.
There is no fixed standard for setting the operating temperature of the laminating machine, but it needs to be comprehensively considered based on various factors such as the materials used, adhesive types, substrate properties, production efficiency requirements, and equipment characteristics. Usually, it is recommended to conduct small-scale trial production before production to determine the optimal temperature setting, while strictly following the technical guidance of material and equipment manufacturers. By controlling the temperature reasonably, it is possible to ensure the smooth progress of the laminating process, improve the adhesive strength of the product, and thus meet the final usage requirements.
