Tosaf develops UV barrier additive for thin food packaging film

Tosaf has developed a new barrier solution UV9389PE EU which ensures clear packaging films, even at low thickness, offer high blocking effect against UV radiation from 200nm to 280nm.

This additive efficiently protects foods from discoloration, vitamin and flavor loss as a result of the degrading effects of artificial light during storage, shipping and on shelf. It prevents food wastage due to premature spoilage.

Tosaf’s new UV barrier additive efficiently protects food and prevents food wastage.

Optical properties, especially transparency of films finished with this new UV blocker are almost completely retained, unlike conventional mineral-based products of this type.

Further benefits include high efficiency even at very low dosages, minimal influences on the behavior during production and further processing of the films, including printing and lamination.

A 50 μm thick polyethylene film shows high efficiency of UV blocker with UV9389PE EU at low dosage.

Application of UV9389PE EU can extend beyond food packaging to other industrial film applications where protection of sensitive goods from UV radiation is required.

The new UV barrier solution complements Tosaf’s broad portfolio of stabilizer masterbatches to maximize resistance against UV light. Their applications reach from agricultural films to stretch, shrink and industrial packaging and big bags (FIBC). They also cover injection molded parts, extruded pipes and sheets, fibers and nonwovens, roofing membranes and so on.
