[Chinese Packaging Network News] Blister packaging is a type of packaging formed by heat-sealing a rigid plastic film with medical aluminum foil. The sealing performance of blister packages is a critical factor that directly affects the quality and safety of pharmaceutical products. This article introduces the use of the MFY-01 Sealing Tester, developed independently by Jinan Languang Electromechanical Technology Co., Ltd., to evaluate the sealing performance of blister packages. It explains the working principle of the equipment and outlines the testing process, offering enterprises a practical reference for monitoring the integrity of their blister packaging.
Blister packaging has become a vital part of the pharmaceutical packaging market due to its advantages in protection, ease of use, and lightweight design. Commonly referred to as PTP packaging, it consists of two main components: a rigid plastic blister and a medicinal aluminum foil. During the packaging process, the medicine is placed into the blisters of the rigid sheet and then sealed with the aluminum foil, creating individual compartments. If one blister is damaged, it should not significantly affect the others. Therefore, ensuring the seal integrity of each blister is crucial. Poor sealing can allow moisture, oxygen, and other gases to penetrate, potentially causing drug degradation or discoloration.
Currently, the standard used for sealing performance testing is GB/T 15171-1994, which applies to flexible packaging made from various materials. In this study, we tested a brand of blister packaging designed for granular pharmaceuticals using the Labthink MFY-01 Sealing Tester.
The MFY-01 operates based on the differential pressure method. During the test, the sample is submerged in water inside a sealed chamber. A vacuum is created, generating a pressure difference between the inside and outside of the package. If there is a leak, air will escape through the weak points, resulting in visible bubbles. Alternatively, the test can also be judged by observing whether the sample expands or returns to its original shape after the vacuum is released.
This equipment is suitable for testing the sealing performance of various types of packaging, including bags, bottles, tubes, cans, and boxes, across industries such as food, pharmaceuticals, medical devices, and electronics. It meets international standards like GB/T 15171 and ASTM D3078.
The device features a vacuum range of 0 to -90 kPa, with three different chamber sizes available. It offers digital preset vacuum levels and retention times, along with automatic pressure compensation technology to maintain consistent testing conditions. The software supports automated unloading and test completion, streamlining the entire process.
The testing procedure involved submerging the samples in water, setting the desired vacuum level, and observing for bubble formation. Out of five samples tested, all showed leaks at varying pressures, except one that remained intact even under maximum vacuum (-90 kPa).
In conclusion, sealing performance is a key aspect of blister packaging, and the MFY-01 Sealing Tester provides an efficient way to assess and improve it. To address limitations of manual data recording, Labthink has developed the i-Process 6200 system, which automates testing and data management, improving accuracy and traceability.
Beyond sealing performance, factors like heat seal strength, water vapor transmission rate, and oxygen permeability also impact drug quality.

Ceramic Bonsai Pot
Material: Ceramic bonsai pots are typically made from clay that has been fired at high temperatures. This results in a durable, yet porous material that allows for adequate airflow and moisture regulation for the bonsai tree's roots. Ceramic pots come in various colors, textures, and finishes, providing options to match different bonsai tree species and personal preferences.
Size and Shape: Bonsai pots come in a range of sizes and shapes to suit different bonsai tree styles and sizes. The pot's size should be proportionate to the size of the bonsai tree and its root system, providing ample room for root growth while maintaining aesthetic balance. Common shapes include rectangular, oval, round, and square, with variations such as cascade pots for cascading-style bonsai trees.
Design and Style: Ceramic bonsai pots come in a variety of designs and styles to complement different bonsai tree species and aesthetic preferences. They may feature traditional Japanese-inspired motifs, modern minimalist designs, or intricate patterns and textures. Some pots are hand-painted or glazed to enhance their visual appeal, while others feature natural earthy tones or rustic finishes.
Drainage Holes: Proper drainage is essential for the health of bonsai trees, as excess water can lead to root rot. Most ceramic bonsai pots come with drainage holes at the bottom to allow water to escape freely. Additionally, some pots may include wire or mesh screens over the drainage holes to prevent soil from washing out while still allowing water to drain.
Weather Resistance: Since bonsai trees are typically kept indoors or in sheltered outdoor locations, ceramic bonsai pots do not require the same level of weather resistance as outdoor pots. However, they should still be durable enough to withstand indoor conditions such as temperature fluctuations and humidity.
Weight: Ceramic bonsai pots can vary in weight depending on their size and design. While smaller pots are generally lightweight and easy to handle, larger pots may be heavier and more challenging to move. The weight of the pot can also provide stability for the bonsai tree, preventing it from tipping over easily.
Maintenance: Ceramic bonsai pots require minimal maintenance but may benefit from occasional cleaning to remove dust, dirt, or mineral deposits. A gentle wipe with a damp cloth is usually sufficient to keep the pot looking its best. Avoid using harsh chemicals or abrasive cleaners that can damage the glazed surface of the pot.
Cost: The cost of ceramic bonsai pots can vary depending on factors such as size, design, craftsmanship, and brand. While they may be more expensive than basic plastic or terra cotta pots, ceramic bonsai pots are considered a worthwhile investment for bonsai enthusiasts looking to enhance the presentation of their trees.
Overall, ceramic bonsai pots combine functionality with aesthetic appeal, providing a suitable and stylish container for showcasing bonsai trees while enhancing the overall beauty of the display. Their versatility in design and size makes them a popular choice for bonsai enthusiasts of all levels.
