Blister packaging machine is an important equipment in modern packaging industry, especially in pharmaceutical and food field. You may encounter a lot of questions when choosing packaging equipment, such as how to choose the right machine, how blister packaging machine works and so on. This article will answer these questions for you in detail and help you better understand how blister packaging machines work and their wide range of applications.
A blister packaging machine is a device specially designed to wrap products in transparent or opaque plastic film (or aluminum foil) and heat-seal it with the underlying material (usually aluminum foil or paper). This type of packaging can protect products from external factors such as air and moisture, and is therefore widely used in the fields of pharmaceuticals, food and electronic components.
Blister packaging is not only widely used by various industries, because of its blister shape and size of the applicable and customized, can significantly improve the production efficiency, product protection safety and personalized appearance display. Its advantages are mainly reflected in the following aspects:
Product protection: to prevent pollution, رطوبت, oxidation and other effects.
Convenient transportation and storage: Compact blister packaging form saves space.
Improve the display effect: transparent blister packaging allows consumers to clearly see the product, increasing purchase confidence.
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.
گرمازا: 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., قرص ها, کپسول ها, آب نبات, و غیره). 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.
با این حال, 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. از این رو, continuous operation is more suitable for larger companies or plants with higher production volumes.
در مقابل, the intermittent mode is more flexible. Each step is performed individually, with short pauses between forming, filling and sealing. Features of this mode include:
انعطاف پذیری: You can adjust the machine at any time to suit different sizes or varieties of product packaging.
مناسب برای تولید دسته ای کوچک: برای تولید در مقیاس کوچک یا شرکت هایی که نیاز به تغییر مکرر نوع محصول دارند, حالت عملکرد متناوب فضای بیشتری را برای تنظیم فراهم می کند و زمان مورد نیاز برای تغییرات تجهیزات را کاهش می دهد.
اگرچه بهره وری حالت عملکرد متناوب به اندازه عملکرد مداوم نیست, انعطاف پذیری آن را به یک انتخاب ایده آل برای خطوط تولید متنوع تبدیل می کند.
تطبیق پذیری بسته بندی تاول به آن اجازه می دهد تا طیف گسترده ای از انواع محصولات را مدیریت کند, به ویژه در صنایع دارویی و غذایی.
انواع محصول دلایل بسته بندی تاول
قرص ها و کپسول ها بسته های بلیستر از رطوبت و آلودگی محافظت می کنند, اطمینان از اثربخشی و ایمنی داروها.
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, و غیره. Choosing the right material for different products and packaging needs is key. به عنوان مثال, 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: کشش سروو دقیق و پایدار است, اطمینان حاصل کنید که موقعیت هر نسخه از تاول همیشه یکسان است.
سیستم برش و جداسازی: سیستم برش دقیق می تواند ورق تاول را به بسته های جداگانه برش دهد, اطمینان از یکپارچگی هر بسته.
درجه اتوماسیون در دستگاه بسته بندی تاول به طور مستقیم بر بهره وری و هزینه تأثیر می گذارد. با پیشرفت تکنولوژی, دستگاه بسته بندی تاول مدرن عملکردهای هوشمند و اتوماسیون را ادغام می کند, که می تواند تولید کارآمد و پایدار را تحقق بخشد.
سیستم کنترل هوشمند: شما به راحتی می توانید پارامترهای دستگاه را از طریق رابط عملیات تنظیم کنید تا انعطاف پذیری تولید را بهبود بخشید.
رد ضایعات هوشمند بصری: سیستم تشخیص بصری می تواند رنگ را تشخیص دهد, اندازه, 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.
