Comprehensive Quality Control for Stretch Wrap Film Performance

Image
Stretch wrap film has become an indispensable packaging solution globally, used to tightly secure goods for efficient transportation and reliable storage. Its versatility stems from its unique properties: lightweight yet strong, highly elastic, self-adhesive, and capable of conforming to any shape without damaging the contents. Produced through advanced cast film extrusion processes, these films boast excellent tensile performance, tear and puncture resistance, high transparency, superior self-adhesiveness, and impressive retraction rates, ensuring packages remain compact and secure. From chemical raw materials and food products to electromechanical goods and textiles, stretch wrap film provides crucial protection, with specialized types like PE (eco-friendly) and PVC (specific uses) catering to diverse needs. The Imperative of Quality Control Given its critical role in safeguarding products throughout the supply chain, the consistent quality of stretch wrap film is paramount. Manufa...

Case Study: Oxygen Barrier Properties of Recycled PET Bottles

Image
Recycling plastic bottles is vital for environmental protection, but it can affect their oxygen barrier properties, making them less suitable for oxygen-sensitive products. Our case study on PET bottles with varying amounts of recycled material found that increasing the recycled content from 25% to 50% only slightly reduced their oxygen barrier. This suggests that using more recycled material does not significantly compromise the bottles' performance. The Problem The growing trend of recycling waste plastic bottles requires an understanding of how reclaimed materials affect a product's performance. For PET bottles, a crucial metric is their ability to act as an oxygen barrier. High oxygen permeability can compromise the quality of packaged goods, limiting the use of recycled materials in food and beverage containers. This study aims to quantify that effect by testing bottles with varying percentages of recycled content. The Test Two types of PET bottle samples were tested...

Why Non-Volatile Residue Detection in Purified Water is Critical for Regulated Industries

Image
Significance of Non-Volatile Residue Detection in Purified Water Purified water is a crucial raw material in industries like pharmaceuticals, biotechnology, and electronics manufacturing. Non-volatile residues are non-evaporating substances (like inorganic salts, organic matter, microbial byproducts) that remain after evaporation at a specific temperature (e.g., 105℃). Detecting Non-Volatile Evaporation residues is important for Regulatory Compliance: Meeting limits set by pharmacopoeias (e.g., For " Purified Water in Containers", the Ph. Eur. European Pharmacopoeia has a requirement for "Residue on Evaporation" of ≤0.001%). Process Stability and Risk Control: Accumulation of residues can alter water conductivity and pH, affect process consistency, clog equipment, corrode metal parts, or interfere with reactions. Drug Production Safety: Heavy metals (e.g., lead, mercury) or endotoxins in residues can contaminate drugs, causing allergic reactions or toxicity in...

Non-Destructive Leak Detector C690H Delivers High-Accuracy, High-Throughput CCI Testing for Pharma Packaging

Image
Labthink C690H Non-Destructive Leak Detector uses a vacuum-based testing method (and also a positive pressure method) to find tiny leaks in different kinds of containers. It's built according to international standards like ASTM F2338 and is particularly useful for checking various packaging in industries like food, pharmaceuticals, daily chemicals, and electronics, such as vials, ampoule, cartridge bottles, infusion bottles and prefilled syringes. How it works It works by placing the sample in a sealed chamber, creating a vacuum, and then using sensors and a fluid dynamics model to calculate the leak rate and the size of the leak based on how fast the pressure drops. It can operate in two modes: Vacuum mode: It creates a negative pressure (vacuum) around the sample and measures how quickly the pressure inside the sample drops. This works well for most packaging types because the vacuum helps to "pull" out any leaks, making them easier to detect. ...

Why Water Vapor Permeability is Critical for OLED Displays and How to Measure it

Image
OLED is extremely sensitivity to water vapor, even microscopic amounts of moisture can lead to rapid degradation, causing unsightly dark spots, short circuits, and significantly shortening the display's lifespan. This is why the OLED Display Water Vapor Transmission Rate Test is so important. The impact of WVTR testing extends far beyond mere measurement; it directly influences the quality, longevity, and market viability of OLED products. Ensuring OLED Device Lifespan and Performance: OLED components are extremely vulnerable to moisture. Water vapor ingress causes metal electrodes to oxidize and organic layers to degrade, leading to critical issues like dark spots and short circuits.To achieve an OLED device lifespan of at least 10,000 hours, the industry recognizes a critical WVTR target of 1 x 10 ⁻⁶ g/(m ²· day). This tester precisely measures and verifies that encapsulation materials meet this stringent requirement. Optimizing Materials and Processes: By testing the ...
