Ensuring regulatory compliance for products such as food contact, toys or medical applications can be a complex and time consuming process.

Ensuring regulatory compliance for products such as food contact, toys or medical applications can be a complex and time consuming process.

PET sheets can be used to make a variety of plastic products and film is often used for tape backing, plastic wrap, medical packaging, and protective coating on windows.

Liquid concentrates are also available as well as solutions formulated with bio-based resins to reduce the carbon footprint of medical plastics. These color and additive solutions are formulated with bio-based polymers and pre-tested raw materials to help reduce the carbon footprint of medical plastics and mitigate the risk of non-compliance.

MEDICAL, FOOD AND TOY REGULATIONS Omnicolor colorants have limited EU food contact compliance, and are not suitable for FDA primary pharmaceutical packaging, cosmetic or medical applications.

This focus on the user should, at a minimum, include age range and ratios, gender ratio, and specific physical, cognitive and sensory limitations (particularly for medical or pharmaceutical devices). You should carefully consider what effect the ambient temperature will have on device usability, particularly in demanding environments such as manufacturing, agriculture, building and construction, and medical/surgical settings.
