Fogging on plastics films is really not all that different than the fog that forms outside; it’s just that, on a plastic film, fog forms on a convenient hydrophobic surface—namely, the film. Water vapor in the form of tiny droplets condenses on a plastic film’s surface when an enclosed mass of air cools to a temperature at its dew point. But plastics material systems are dynamic too.

Additionally, plastic prefilled syringes can be color-coded for easy identification and customized to meet specific opacities in polypropylene (PP) resin, while laser marking additives can help create precise, solvent-free markings.  Formulated with pre-tested raw materials, this range of additives helps enhance the performance and functionality of plastics used in medical devices and pharmaceutical packaging and mitigate the risk of non-compliance.

Plastics are a preferred material for IVD devices and kit components due to their inherent properties, customizability, and lightweight nature. Find out how part design can reduce stress in molded plastic parts and improve ESCR in your products
