Application of Transparent Packaging OnCap Light Shielding Additives

PolyOne has released OnCap light-shielding additives for transparent packaging that effectively absorb UV and visible light, protect light-sensitive foods or medicines from light pollution, and reduce the risk of spoilage.

At CHINAPLAS 2014, PolyOne has released OnCap light shielding additives for transparent packaging. The new solution effectively absorbs UV and visible light, protects light-sensitive foods or medicines from light pollution, and reduces the risk of spoilage. In some cases, the use of OnCap light-shielding additives eliminates the need for additional coatings or films, reduces material consumption, and enables sustainable development.

SayEngLee, general manager of PolyOne's pigments and additives Asia, said: Transparent packaging is very popular among consumers. It stands for health, freshness, and purity, but it also exposes the product inside the package to light, increasing the risk of spoilage. OnCap Light Shielding Additives provide better light stability and consistent shading for transparent packaging materials, protecting the quality of the products in the package and the reputation of food manufacturers.

OnCap light shielding additives were originally used in disposable medical infusion sets, pharmaceutical packaging, pre-filled syringes, packaging films, bottles, food wrappers and packaging films. The additive can help processing companies and manufacturers to protect the efficacy of drugs, protect the flavor and nutritional value of foods and beverages, and improve the shelf life of products. This product can also be adjusted to achieve different light absorption ranges, providing customized services for transparent packaging products.

This new additive masterbatch is pelletized and is suitable for injection molding, thermoforming or extrusion processes. It can also increase the shading properties of most transparent polymers, such as polyethylene (PE), polypropylene (PP), polycarbonate (PC), polyethylene terephthalate (PET), polystyrene ( PS). FDA-compliant PET and PS materials can be used for the packaging of medical and health products.
