🧪 Why are certified labels more expensive? Understanding the value of testing

UL Solutions has very stringent evaluation criteria for approved components. Purchasing high-quality labels is to avoid the risk of future label failure due to environmental factors. Testing includes:

• Environmental adaptability testing: This includes high humidity, occasional water contact, high temperature, sunlight exposure (UV resistance), and chemical contact testing.
• Physical performance inspection: After testing, the label is checked for curling, wrinkling, shrinkage, or loss of adhesion.
• Legibility assessment: Ensuring that the text remains clear, stain-resistant, and firmly adhered after environmental challenges.

💡 Purchasing Specialist: What is "Label Adoption"?

Label manufacturers and printers can benefit from choosing to use approved label materials (such as PGGU2 category substrates, adhesives, and laminations). This process, called "Label Adoption," effectively simplifies the subsequent approval process for finished labels.

Important Note: All approved labeling systems fall under the UL Solutions Tracking and Inspection Service program. This means that products must be continuously manufactured in accordance with certification requirements at the factory to ensure the consistency and safety of the final product.
