The building materials industry also manages the moisture barrier properties in architectural components to ensure the correct moisture levels in the internal spaces of buildings. Optoelectronic devices based on organic material, generally named OLEDs , need an encapsulation with low values of WVTR to guarantee the same performances over the ...
Barrier properties, durability, visibility, sterility and strength need to be controlled; usually with documented test results for initial designs and for production. Assurance of sterility and suitability for use are critical. For example, medical devices and products are often sterilized in the package.
Several common factors can include: assurance of patient safety, assurance of the efficacy of the drug through the intended shelf life, [1] uniformity of the drug through different production lots, thorough documentation of all materials and processes, control of possible migration of packaging components into the drug, control of degradation ...
For many years, desiccants have been used to control the water vapor in a closed package. A desiccant is a hygroscopic substance usually in a porous pouch or sachet which is placed inside a sealed package. They have been used to reduce corrosion of machinery and electronics and to extend the shelf life of moisture-sensitive foods. With ...
The SBC grade has over twice the barrier to moisture and oxygen per gram coating weight compared to the historic grades. The most common structures using the super barrier PVDC are triplex configurations 250μ PVC/25μ PE/120gsm PVDC up to 250μ PVC/25μ PE/180gsm PVDC, with WVTR of 0.11 to 0.06 g/m 2 per day and available from various ...
Specialists in design and testing of packaging for temperature sensitive products are often needed. These may be consultants, independent laboratories, universities, or reputable vendors. Many laboratories have certifications and accreditations: ISO 9000s, ISO/IEC 17025, etc.
Multi-layered packaging are multilayer or composite materials using innovative technologies aimed to give barrier properties, strength and storage stability to food items, new materials as well as hazardous materials. [1] Multiple layers are formed by coextrusion, lamination, or various coating technologies. The material of construction of ...
The moisture requirement of iron-based scavengers makes them ineffective in moisture sensitive applications. The performance of oxygen scavengers is affected by ambient temperature and relative humidity. [9] Newer packaging technologies may use oxygen scavenging polymers to prevent accidental ingestion of oxygen scavengers. [8]
