Este artículo responderá estas preguntas en detalle y lo ayudará a comprender mejor cómo funcionan las máquinas empacadoras de blister y su amplia gama de aplicaciones..
Una máquina envasadora de blister es un dispositivo especialmente diseñado para envolver productos en film plástico transparente u opaco. (o papel de aluminio) y sellarlo con calor con el material subyacente (generalmente papel de aluminio o papel). Este tipo de embalaje puede proteger los productos de factores externos como el aire y la humedad., y por lo tanto es ampliamente utilizado en los campos de la industria farmacéutica., alimentos y componentes electrónicos.
El embalaje tipo blíster no sólo es muy utilizado en diversas industrias, debido a su forma de ampolla y tamaño de la aplicable y personalizada, puede mejorar significativamente la eficiencia de producción, protección del producto seguridad y visualización de apariencia personalizada. Sus ventajas se reflejan principalmente en los siguientes aspectos:
Protección del producto: para prevenir la contaminación, humedad, oxidación y otros efectos.
Transporte y almacenamiento convenientes: El formato de embalaje tipo blíster compacto ahorra espacio.
Mejorar el efecto de visualización: El embalaje tipo blíster transparente permite a los consumidores ver claramente el producto., aumentar la confianza de compra.
The working principle of blister packaging machine can be simply divided into three main steps: molding, filling and sealing. These three steps are the core of the packaging process and each step is critical.
Blister molding can be achieved by two different methods: hot molding and cold molding.
Thermoforming: This method is mainly used for plastic materials such as PVC. by heating, the plastic is softened and then pressed into the desired blister shape using a mold. This method is suitable for the packaging of most tablets and capsules.
Cold Forming: If you need to package a product that is sensitive to temperature (such as certain pharmaceuticals), you will need to use a cold forming process. Cold forming usually uses aluminum foil or composite materials where the material is pressed into a blister shape under high pressure. This method provides better moisture resistance, but the molding speed is relatively slow.
After the molding is complete, an automated filling system precisely fills the blister with the product (e.g., tabletas, cápsulas, golosinas, etc.). The accuracy of this step is critical, as the product needs to be placed accurately into each blister to avoid gaps or misalignment.
The next step is the sealing process. The sealing process usually employs either heat-sealing or cold-sealing techniques to tightly bond the blister to the underlying material (e.g., aluminum foil or paper), ensuring a tight seal of the package and the safety of the product. Heat sealing uses high temperatures to melt the two layers of material, while cold sealing relies on pressing and special adhesives and is suitable for packaging sensitive products.
When understanding the operating modes of a blister packaging machine, you may come across two different modes of operation: continuous operation and intermittent operation. These two modes are suitable for different production needs.
In continuous operation mode, the forming, filling and sealing processes of a blister packaging machine are synchronized and the entire process is not interrupted. The advantages of this mode are:
High efficiency: under continuous operation mode, the packaging machine is able to handle more products per unit time, which greatly improves the production efficiency.
Suitable for high volume production: If your production line needs to run for a long period of time and on a large scale, continuous operation mode can minimize downtime and increase production capacity.
Sin embargo, there are some challenges with this mode. As all steps are synchronized, the equipment requires a very high level of accuracy and is more complex to maintain and commission. Therefore, continuous operation is more suitable for larger companies or plants with higher production volumes.
In contrast, the intermittent mode is more flexible. Each step is performed individually, with short pauses between forming, filling and sealing. Features of this mode include:
Flexibility: You can adjust the machine at any time to suit different sizes or varieties of product packaging.
Suitable for small batch production: For small-scale production or companies that need to change product types frequently, the intermittent operation mode provides more room for adjustment and reduces the time required for equipment alterations.
Although the productivity of intermittent operation mode is not as high as continuous operation, its flexibility makes it an ideal choice for diversified production lines.
The versatility of a blister packer allows it to handle a wide range of product types, especially in the pharmaceutical and food industries.
Product types Reasons for blister packers
Tablets and capsules Blister packs provide protection against moisture and contamination, ensuring the effectiveness and safety of medicines.
Food and Snacks Blister packs extend the shelf life of food products while facilitating presentation and storage.
Electronics Small electronic components such as resistors, capacitors, the use of blister packaging can avoid friction and damage.
Medical Devices Blister packaging is often used to aseptically package disposable medical devices to ensure safe use.
Whether your products are pharmaceuticals, food or electronic components, blister packaging machines provide good protection and presentation.
In the process of blister packaging, the quality of molding directly affects the final packaging effect. You need to make sure that the temperature and pressure during the molding process are at the proper level to ensure the firmness and consistency of the package.
Temperature control in the blister thermoforming process directly affects the quality of the blister molding, too high a temperature may lead to deformation or soft hardness of the blister cavity, while too low a temperature will affect the blister molding properties leading to the blister cavity can not be formed. Controlling the heating temperature and pressure can ensure that the shape and size of each blister is consistent.
According to your product requirements, you also need to choose the appropriate molding material. Common blister materials include PVC, PVE and aluminum foil, etc.. Choosing the right material for different products and packaging needs is key. For example, PVC is suitable for packaging most pharmaceuticals, while aluminum foil offers better barrier properties for light-sensitive products.
The core components of a blister packaging machine determine its performance and efficiency. Below are the main components:
Forming Mold: The mold determines the shape and size of the blister, and an accurate mold ensures packaging consistency.
Material Filling System: With an automated filler, products can be precisely filled into each blister.
Sealing System: The sealing system ensures that the blister and the sealing material are tightly bonded through hot or cold sealing technology to keep the product sealed.
Traction System: Servo traction is precise and stable, ensuring that the position of each version of the blister is always the same.
Cutting and Separation System: The precise cutting system can cut the blister sheet into individual packages, ensuring the integrity of each package.
The degree of automation in a blister packaging machine directly affects productivity and cost. With the advancement of technology, modern blister packaging machine integrates intelligent and automation functions, which can realize efficient and stable production.
Intelligent control system: you can easily adjust the parameters of the machine through the operation interface to improve the flexibility of production.
Visual Intelligent Rejection of Waste: The visual recognition system can identify the color, size, shape of each blister plate material already whether it is broken and lack of material and other issues automatically reject the unqualified products, to ensure the consistency of product quality.
Automatic fault detection: automation system can real-time monitoring of equipment operation, timely detection of faults and issue an alarm to reduce downtime.
Blister packaging machine is a key tool in modern packaging equipment, which can improve production efficiency, protect products and enhance market competitiveness. Whether you are engaged in pharmaceutical, food or other industries, understanding the working principle of blister packaging machine will help you make better equipment choices and optimize the production process.
