The pharmaceutical packaging industry is an industry with extremely strict requirements on the production environment. The quality of packaging materials is directly related to the safety and effectiveness of drugs. In this process, the chill roller has become an indispensable and important equipment in the pharmaceutical packaging industry because of its key role in temperature control, material handling and product quality assurance.

This article will discuss in detail why the pharmaceutical packaging industry needs to use a cooling roller and analyze its specific application in different production links.

Why does the pharmaceutical packaging industry need to use a chill roller?

The production process of pharmaceutical packaging materials includes extrusion, coating, printing and lamination. Each link has very high requirements for temperature control and material handling. The chill roller plays a vital role in these links. Its main functions include: temperature control, material handling, and product quality assurance.

    ● Temperature control: The chill roller can quickly and evenly reduce the temperature of the extruded or coated material to prevent the material from deforming or degrading due to overheating.

    ● Material handling: The chill roller provides stable support and traction during material handling to ensure the flatness and thickness uniformity of the material.

    ● Product quality assurance: Through precise temperature control and stable material handling, the cooling roller can effectively improve the surface quality and physical properties of the packaging material, ensuring the high quality of the final product.

What are the application links of the chill roller in the pharmaceutical packaging industry?

The production process of pharmaceutical packaging materials includes multiple key links, and each link has different requirements and functions for the chill roller. The main application links of the cooling roller in the pharmaceutical packaging industry are: extrusion, coating, printing, and compounding.

Extrusion link:

The extrusion link is the first step in the production of pharmaceutical packaging materials. The plastic particles are melted and extruded into films or sheets through an extruder. The temperature of the extruded material is usually high, and it must be cooled quickly to maintain its physical properties and dimensional stability. The role of the cooling roller in this link is particularly important.

    ● Rapid cooling: The extruded plastic material needs to be cooled quickly to be shaped. The cooling roller quickly conducts heat away through contact with the surface of the material, reduces the material temperature, and prevents deformation and performance degradation caused by overheating.

    ● Ensure flatness: The cooling roller provides uniform pressure during the cooling process to ensure the flatness and thickness uniformity of the material, and avoid the phenomenon of corrugation and uneven thickness.

Coating process:

The coating process is the process of applying a protective layer or functional coating to the surface of the pharmaceutical packaging material. The coated material usually needs to be cooled quickly to solidify the coating and improve the adhesion and stability of the coating. The role of the cooling roller in the coating process includes: coating solidification and improving surface quality.

    ● Coating solidification: The coated material needs to be cooled quickly to solidify the coating. The cooling roller improves the adhesion and durability of the coating through uniform cooling effect, and prevents the coating from falling off or deteriorating.

    ● Improve surface quality: The chill roller provides stable support and traction during the coating process, ensuring the smoothness and uniformity of the material surface and improving the overall quality of the packaging material.

Printing process:

The printing process is the process of printing patterns and texts on pharmaceutical packaging materials. The printed material also needs to be cooled to fix the ink and prevent the ink from diffusing or deforming. The role of the cooling roller in the printing process is mainly reflected in: ink fixation and prevention of deformation.

    ● Ink fixation: The printed material needs to be cooled quickly to fix the ink. The cooling roller prevents the ink from spreading by cooling quickly, improving the clarity and color vividness of the printed pattern.

    ● Prevent deformation: The cooling roller provides stable support during the printing process to prevent the material from deforming due to temperature changes, ensuring the stability and consistency of the printing quality.

Composite link:

The composite link is the process of laminating different materials together to form a multi-layer pharmaceutical packaging material. The composite material usually needs to be cooled quickly to solidify the adhesive layer to ensure the tight bonding and stability of each layer of material. The role of the chill roller in the composite link includes: bonding layer solidification and maintaining interlayer stability.

    ● Bonding layer solidification: The composite material needs to be cooled quickly to solidify the adhesive layer. The cooling roller ensures the tight bonding of each layer of material through uniform cooling effect to prevent delamination and falling off.

    ● Maintain interlayer stability: The cooling roller provides stable support and traction during the composite process to ensure the flatness and thickness uniformity of the material and improve the overall quality and performance of the composite material.

Practical application case analysis of chill rollers

In order to better understand the application of cooling rollers in the pharmaceutical packaging industry, we can analyze its role and effect in detail through some actual cases.

Case 1: Extrusion process improvement of a large pharmaceutical packaging plant

In the production process of a large pharmaceutical packaging plant, the traditional cooling method cannot meet the needs of efficient cooling, resulting in frequent deformation and performance degradation of the material. By introducing efficient chill rollers, the extrusion process of the plant has been significantly improved. The rapid cooling effect of the cooling roller effectively prevents the material from overheating and deformation, ensures the dimensional stability and physical properties of the material, and improves production efficiency and product quality.

Case 2: Coating process optimization of a pharmaceutical packaging company

In the coating process of a pharmaceutical packaging company, due to incomplete curing of the coating, the coating adhesion is poor and easy to fall off. By using cooling rollers, the coated material can be cooled quickly, the coating is fully cured, and the adhesion and durability are improved. The uniform cooling effect of the cooling roller also improves the smoothness and uniformity of the material surface, significantly improving the quality and market competitiveness of the packaging material.

Case 3: Printing process upgrade of a pharmaceutical packaging company

During the printing process of a pharmaceutical packaging company, the traditional cooling method could not effectively fix the ink, resulting in blurred printed patterns and dull colors. By introducing efficient chill rollers, the printed material can be cooled quickly, the ink is fully fixed, the printed pattern becomes clearer, and the color becomes more vivid. At the same time, the stable support and traction of the cooling roller ensure the flatness of the material, significantly improving the printing quality.
