How long is the production cycle of BOPP color thermal sensitive synthetic paper?

The production cycle of BOPP color thermosensitive synthetic paper is a relatively complex process involving multiple process steps and factors, making it difficult to provide an exact time range. However, based on general production processes and industry experience, the main stages and time considerations of its production cycle can be roughly estimated.

1、 Main production stages

Raw material preparation and mixing:

Mix polypropylene resin, functional fillers (such as pigments and dyes), and various additives in a certain proportion evenly. The time for this step depends on the efficiency of the mixing equipment and the pre-treatment of the raw materials.

Plasticization and extrusion:

Feed the mixed raw materials into the extruder for plasticization and melt them into a uniform melt. The processing temperature and screw speed of the extruder can affect the plasticizing effect and extrusion speed, thereby affecting the production cycle.

Casting and cooling:

Squeeze the melted polypropylene melt through the die into thick sheets and rapidly cool them into regular thick sheets. The cooling process usually uses chilled rollers and a water tank, with temperature controlled within a certain range. The time for this step depends on the efficiency of the cooling equipment and the cooling conditions.

Stretching treatment:

Perform longitudinal and transverse tensile treatment on the cast sheet to improve the tensile strength and physical properties of the film. During the stretching process, it is necessary to control the temperature and stretching speed of the preheating zone, stretching zone, and shaping zone. The time for this step depends on the performance of the stretching equipment and the stretching process parameters.

Surface treatment and coating:

Perform corona treatment or other surface treatments on the stretched film as needed to improve its surface tension. Then apply a thermosensitive coating, a base coating, and a protective layer on the surface of the film. The coating process requires strict control of the composition, concentration, and coating amount of the coating liquid. The time for this step depends on the efficiency of the surface treatment equipment and coating equipment, as well as the coating process parameters.

Rolling, slitting, and time processing:

Roll the coated film into a uniform large roll, and then cut the large roll into appropriate sizes according to customer requirements. Finally, aging treatment is performed to improve the physical properties and stability of the film. The time for this step depends on the efficiency of the winding, slitting, and aging equipment, as well as the processing parameters.

2、 Time consideration factor

Equipment efficiency: The performance and efficiency of production equipment directly affect the production cycle. Advanced equipment typically has higher production efficiency and more stable performance, thereby shortening the production cycle.

Process parameters: The setting and adjustment of production process parameters can also affect the production cycle. Reasonable process parameters can improve production efficiency and product quality, thereby shortening the production cycle.

Raw material quality: The quality and stability of raw materials also have a certain impact on the production cycle. High quality raw materials can reduce the failure rate and scrap rate in the production process, thereby shortening the production cycle.

Personnel operation: The operational skills and proficiency of production personnel can also affect the production cycle. Skilled operators can adjust equipment parameters and handle production failures faster, thereby shortening the production cycle.

3、 Production cycle estimation

Due to various factors affecting the production cycle of BOPP color thermosensitive synthetic paper and its difficulty in quantification, it is difficult to provide an exact time range. However, based on industry experience, the entire production process from raw material preparation to finished product delivery may take several days to weeks. The specific time depends on the comprehensive influence of multiple factors such as production scale, equipment efficiency, process parameters, raw material quality, and personnel operation.

In summary, the production cycle of BOPP color thermosensitive synthetic paper is a relatively complex process and it is difficult to provide an exact time range. In actual production, adjustments and optimizations should be made according to specific situations to improve production efficiency and product quality.
