Advanced Packaging Test

Condom packaging integrity is a critical factor in ensuring the safety and effectiveness of condoms. Leaks in the packaging can lead to lubricant loss, reducing the effectiveness of the product. To guarantee the quality of condom packaging, manufacturers employ various testing methods, including nondestructive testing techniques. Condom packaging typically consists of a foil pouch or a cardboard box with a plastic liner. The packaging serves as a barrier between the condom and the external environment, protecting it from damage and contamination. It also provides information about the product, such as size, brand, and expiration date. Nondestructive packaging leak testing involves detecting leaks in the packaging without damaging the product itself. This test offers several benefits, including Accuracy: The methods used are highly accurate in detecting leaks, even small ones. Efficiency: Testing can be performed quickly and efficiently, allowing for high-throughput testing. Non-destruc...

In the pharmaceutical industry, where product integrity is paramount, ensuring the safety and efficacy of medications is of utmost importance. Traditional destructive testing methods can lead to product wastage and delay time-to-market. This is where non-destructive package leak detection shines. Vacuum decay and pressure decay are two common methods used in non-destructive package leak detection. In vacuum decay, the package is placed under a vacuum. Leaks will allow air to enter, increasing the pressure. Conversely, in pressure decay, the pressure within a sealed package is measured. A leak will cause the pressure to drop more rapidly. Non-destructive leak detection is beneficial for pharmaceutical packaging. By avoiding destructive testing, non-destructive leak detection prevents product wastage, ensuring that valuable medications are not lost. The testing process is significantly faster, reducing turnaround time and accelerating product release. These methods provide reliable and a...

The barrier properties of films, such as their ability to resist the permeation of gases like oxygen and water vapor, are crucial for the packaging of a wide range of products, including food, pharmaceuticals, and electronics. These properties are influenced by various factors, among which the thickness of the film plays a significant role. This study explores the relationship between film thickness and barrier performance, focusing on oxygen and water vapor transmission rates. Understanding the barrier properties of films is essential. Higher oxygen and water vapor barrier properties can extend the shelf life of products by preventing oxidation, moisture loss, and contamination. Barrier films help maintain the quality and integrity of products during storage and transportation. Knowledge of barrier properties aids in the selection of appropriate packaging materials for specific products and applications. Many industries have regulations regarding the barrier properties of packaging ma...

Leather is widely used in clothing, footwear, foot pads, seat pads, sofas, and other products. Its permeability significantly affects the comfort of these products, especially those in direct contact with the human body, such as leather clothing and footwear. If leather has poor permeability, it cannot effectively dissipate the sweat and heat generated by the human body, leading to a damp and hot feeling during wear, resulting in a negative wearing experience for consumers. The collagen fiber gaps in leather serve as channels for gas and energy exchange between the inside and outside of the leather. Processes such as acid-base treatment, softening, texturing, greasing, tanning, and finishing during leather production can affect the uniformity, size, and quantity of these collagen fiber gaps. Therefore, testing permeability can provide data for adjusting and improving leather production processes, ultimately enhancing the quality of leather products. The standard test method for measur...

The increasing demand for sustainable and biodegradable materials has led to a surge in research on plant-based alternatives to traditional plastics. Tomato peels, a byproduct of tomato processing, offer a promising source for the development of such materials. This study focuses on the water vapor barrier properties of a film made from tomato peels, a critical factor for various applications, including food packaging and medical use. To determine the water vapor transmission rate (WVTR) of the film, the cup method, also known as the gravimetric method, was employed. Labthink C360H water vapor transmission rate tester was used for this purpose. The testing procedure involved placing the film between a desiccant-filled cup and a lid, creating a sealed chamber. The testing procedure involved placing the film between a desiccant-filled cup and a lid, creating a sealed chamber. The equipment then measured the weight change of the cup over time to determine the WVTR. The WVTR of the tomato...

The increasing use of non-PVC multi-layer coextruded film infusion bags in healthcare sector necessitates rigorous quality control to ensure the safety and efficacy of medications. One critical aspect of quality assurance is the testing of these bags' sealing performance. Heat Sealing Strength Testing The heat sealing strength of a non-PVC infusion bag is a crucial indicator of its integrity. A poorly sealed bag can lead to leakage, contamination, and loss of medication. This test ensures that the sealed edge is strong enough to withstand the pressure of the infused liquid and prevent leakage during handling and storage. To assess this property, Labthink Auto Tensile Testers can be employed. Labthink C610M Auto Tensile Tester is professionally applicable to measurement of tensile, peeling, deformation, tearing, heat sealing, adhesive, puncture force, opening force, pulling force and low speed unwrapping force as well as other properties of plastic films, composite materials, soft ...

Introduction The sterilization process is a critical step in food processing, ensuring the safety of products. However, this process can also influence the properties of packaging materials. This study investigates the effect of sterilization on the oxygen barrier properties of PVDC composite film, a commonly used packaging material. Materials and Methods PVDC composite film samples were subjected to a sterilization process. The oxygen permeability of these samples was measured both before and after sterilization using Labthink C230H Oxygen Transmission Rate Test System. This system employs the coulometric method, also known as the equal-pressure method, to determine oxygen transmission rates. The test procedure involved cutting samples from the film, clamping them into the test chambers of the instrument, and setting parameters such as temperature and humidity. High-purity oxygen and nitrogen were introduced into the upper and lower chambers, respectively. The oxygen that permeated t...
