Cosmetic packaging plays a critical role in preserving the product and influencing consumer perception. To ensure quality, various tests are conducted on the packaging materials and final containers.

Preserving the Product:

Barrier Property Testing: This assesses the material's ability to block oxygen, water vapor, and organic gases. Instruments like the Labthink C203H measure oxygen permeation rate, while theC306H checks vapor permeation rate. A new tester, with Labthink C403H, both oxygen and water vapor transmission rate can be tested at once. C130H evaluates organic gas permeation crucial for fragrance preservation.

C203H Oxygen Transmission Rate Test System is based on Coulometric oxygen analysis sensor and equal pressure test method, and is conforming to ASTM D 3985 and other standards. It provides high precision and efficiency oxygen permeability tests for high barrier materials. It is suitable for testing thin films, sheets and related materials in the fields of food, medicine, medical devices and others.

C306H Water Vapor Transmission Rate Test System is designed and manufactured based on infrared sensor method and conforms to the requirements of ASTM F1249 and ISO 15106-2. This instrument can be used to measure the water vapor transmission rate of barrier materials with high and medium moisture barrier properties with a wide testing range and high testing efficiency.

C403H Oxygen /Water Vapor Transmission Rate Test System is based on the testing principle of Coulometric oxygen sensor and infrared water vapor sensor. It is designed and manufactured according to ASTM D3985、ASTM F1249，ISO 15106-2 and other standards to provide high precision and efficiency oxygen and water vapor transmission rate tests for high barrier materials.

Sealing Performance Testing: Leakage points are identified using positive or negative pressure methods. The Labthink C660M tester can assess sealing strength of tubes, caps, and bags.

Head Space Air Analysis: The Labthink C650M Headspace Gas Analyzer measures the remaining air volume in sealed packages, particularly oxygen and carbon dioxide. This ensures the air content doesn't compromise product shelf life.

Ensuring Appealing Packaging:

Printing Quality Testing: Regular tests include ink abrasion resistance (scratching), ink fastness, and color accuracy. The Labthink RT-01 Abrasion Tester is commonly used.

Adhesive Tag Testing: Adhesive performance is evaluated through tests like the tilt iron ball rolling test (measures initial adhesion) and peeling strength tests (C610H Tensile tester).

Easiness of Opening: Torque testers assess the force required to open/close bottle caps, ensuring a user-friendly experience. Packages with tearing sections are evaluated for tearing performance and friction, considering both material properties and consumer interaction.

In conclusion, by employing these test methods and instruments, cosmetic packaging manufacturers can ensure their products meet quality standards for both preservation and consumer appeal. This knowledge helps identify and address potential issues during the design phase, leading to improved product usability, protection, and overall market success.

Moisture Resistance Testing of Thermal Conductive Silica Gel Pads

Thermal conductive silica gel pads, crucial components in electronic devices, require effective moisture resistance to ensure optimal performance and longevity. This article delves into a comprehensive testing method for evaluating the water vapor transmission rate (WVTR) of these pads. Electronic components are sensitive to moisture, which can lead to corrosion, short circuits, and reduced reliability. Thermal conductive silica gel pads, often used to facilitate heat dissipation between electronic chips and radiators, play a vital role in preventing moisture ingress. Their moisture resistance properties directly impact the protection of sensitive internal components. The electrolytic sensor method, a widely recognized standard, is employed to measure the WVTR of thermal conductive silica gel pads. This technique involves creating a controlled environment with a high humidity chamber on one side and a low humidity chamber on the other. A sample of the thermal conductive silica gel pad ...

Quality Requirements of Lithium Ion Battery Separators

Business Challenge Lithium-ion batteries have one of the best energy-to-weight ratios, no memory effect, and a slow loss of charge when not in use. This makes them one of the most popular types of batteries for portable consumer electronics in today’s marketplace. Lithium-ion batteries can be found in cameras, laptops, power tools, toys and more. However, as recent well-publicized recalls demonstrate, they can pose a risk of fire and overheating. In addition, they can suffer from a reduced lifespan if not properly treated. As a result, new and stricter requirements are being implemented globally to address potential hazards, leaving manufacturers and purchasers of products containing lithium-ion batteries to meet increasing requirements and overcome safety concerns. Lithium Ion Battery Separators A Lithium Ion battery Separator is a permeable membrane placed between the anode and cathode of a battery. The main function of a separator is to keep the positive and negative electr...

Introducing Vacuum Decay Testing Method for Pharmaceutical Packaging Integrity

Maintaining the integrity of pharmaceutical packaging is fundamentally essential for safeguarding product efficacy and patient safety, and vacuum decay testing stands as a highly reliable non-destructive method for verifying this integrity. This technique, particularly effective for blister packs, vials, and pre-filled syringes, identifies leaks without compromising product sterility or efficacy. Vacuum decay testing leverages the principle that a sealed package, when subjected to a vacuum, will exhibit predictable pressure changes if it's leak-free. Conversely, a leaking package will show a different pressure profile. Specific Vacuum Decay Techniques: Differential Pressure Transducers: These precise sensors measure the difference in pressure between the vacuum chamber and a reference chamber. This allows for detection of very small leaks. Absolute Pressure Sensors: These sensors measure the absolute pressure within the vacuum chamber, providing data to determine the rate of pres...
