Self-Adhesive Label Testing Solution

Industry Overview

Self-adhesive labels are widely used in food, daily chemical, pharmaceutical, logistics, electronics, and automotive industries. Their adhesion, print durability, substrate quality, and weather resistance directly affect product identification, packaging quality, compliance, and market acceptance.

 

A professional label testing solution helps enterprises:

Ensure stable adhesive performance, including peel strength, initial tack, and holding power.

Support substrate and adhesive R&D, optimize printing and die-cutting processes with reliable test data.

Meet industry regulations and compliance requirements through harmful substance and heavy metal testing.

Testing Methods

All tests are conducted according to national and international standards (ASTM, ISO, etc.) to ensure accurate, reliable, and repeatable results.

Peel Strength Test: Measures peel force, tack, and shear failure temperature.

Tensile Test: Evaluates substrate strength and elongation performance.

Holding Power Test: Assesses long-term adhesion under constant load.

Environmental Simulation Test: Verifies aging resistance, color stability, and adhesion retention under temperature, humidity, and UV exposure.

RoHS Test: Detects hazardous substances and heavy metals in label materials.
