For businesses relying on PET packaging, protecting products from the damaging effects of UV light is paramount. Sunlight and artificial lighting can degrade sensitive ingredients, leading to color fading, loss of flavor, and reduced nutritional value. This not only impacts product quality but also the brand's reputation. As a leading UV absorber manufacturer, we understand the critical role these additives play. This article will guide you on how to choose the right UV absorber for your PET packaging to ensure optimal product protection and longevity.

Understanding the Threat: UV Degradation in PET Packaging

Polyethylene terephthalate (PET) is a versatile and widely used material for packaging due to its clarity, strength, and barrier properties. However, PET itself offers limited protection against UV radiation, particularly wavelengths above 320 nm. When products packaged in PET are exposed to UV light, a cascade of degradation can occur. For instance, vitamins like A, B2 (riboflavin), B6, B12, and folic acid are particularly susceptible. Colors can fade, flavors can turn off, and overall product integrity can be compromised. This necessitates the use of specialized UV absorbers.

Key Features to Look for in a PET UV Absorber:

When sourcing UV absorbers for PET packaging, consider these crucial features:

  • Broad UV Spectrum Absorption: The most effective UV absorbers should protect against a wide range of UV wavelengths, ideally up to 400 nm, to cover the susceptibility of various ingredients.
  • Low Dosage Requirement: High efficiency means you can use less additive, making it more cost-effective. Look for absorbers that provide significant protection at low concentrations.
  • Colorless and Odorless: To maintain the aesthetic appeal of clear packaging and the sensory profile of the product, the UV absorber should not impart color or odor.
  • Thermal Stability and Compatibility: The absorber must withstand processing temperatures during PET manufacturing and be compatible with the PET resin to prevent migration or plate-out.
  • Food Contact Compliance: For packaging intended for food, beverages, or pharmaceuticals, ensure the UV absorber is FDA and EU approved for direct food contact.
  • Polymer-Bound Formulations: These formulations minimize migration, ensuring the additive stays within the PET matrix and doesn't contaminate the product or processing equipment.
