ClearShield® 390B Extends Shelf Life and Maintains Nutritional Integrity in Food and Beverages

Once a food or beverage reaches store shelves, how long will that product maintain its visual and nutritional value? This length of time, known as shelf life, measures the ability of foods and drinks to remain true to the nutritional content declared on the label and to maintain the desired color, taste, and aroma. As brands consider packaging options, it’s important to understand how UV rays affect package contents and what steps they can take to extend shelf life and maintain product integrity.

The 80/120 Rule: How UV Rays Affect Product Shelf Life

UV rays cause products to degrade much quicker than they should, which impacts consumer satisfaction, nutritional content, and cost. UV-caused degradation can also result in non-compliance with food labeling regulations. For example, the U.S. Food and Drug Administration’s 21 CFR Part 101 requires nutrient levels to remain similar to the values stated on the product label.

To meet federal requirements, products must retain between 80 and 120 percent of the stated nutritional content. Known as the 80/120 rule, this guideline addresses two potential problems:

  • Changes in product integrity—As ingredients degrade, they can cause changes in product integrity, which affects consumer appeal. Attempting to compensate by increasing the volume of certain ingredients may result in too high a percentage, which also has the potential to affect the product’s compliance with FDA guidelines.
  • Changes in chemical structure—UV rays can also cause changes to the molecular structure of nutrients. UV light accelerates both degradation and destructive interaction between vitamins, rendering those vitamins ineffective.

Traditional solutions to this problem include using opaque packaging or incorporating UV stabilizers into the product itself. However, these solutions impact both visual appeal (consumers can’t see the product) and clean labeling (consumers want simple, natural ingredients).

Solve Shelf Life Problems With ClearShield® 390B

ClearShield® 390B helps brands solve both of these challenges by incorporating UV protection into the product packaging itself. ClearShield™ UV Absorbers will:

  • Protect Product Integrity—Superior UV protection prevents changes in taste, aroma, and color so that products retain their branded appeal.
  • Support Clean Labeling—Because UV protection is built into the packaging and will not migrate into foods and beverages, ClearShield® 390B supports consumer-friendly labeling and builds trust in your brand.
  • Maintain Nutritional Value—In keeping with FDA guidelines, brands can use ClearShield® 390B to extend the shelf life of vitamins and ingredients so that products remain true to the nutritional values stated on the label. Milliken studies have demonstrated significant improvements in ingredient shelf life for products packaged with ClearShield® 390B-enhanced packaging as compared with standard PET:

Without sufficient UV protection, foods and beverages quickly degrade on store shelves or in the homes of consumers. With ClearShield® 390B, brands can prevent degradation and protect products from higher UV wavelengths than they can with other UV blockers. That means products not only receive more effective UV protection, but also maintain consumer appeal and profitability over time.
