Products Available from ITM-LAB:
-
Paper Packaging Series:
- A. Cosmetics cartons must withstand the pressure from stacked boxes during storage and transport. Testing the compressive strength of packaging under stacking conditions is essential.
- B. Products may be affected by vibration during transport. Simulating transport vibrations using devices like the automotive vibration simulator can help assess product reliability under such conditions.
- C. Testing the drop resistance of products, especially during handling or usage. Equipment like the single-wing drop tester tests product durability by simulating drops from various heights, including free fall tests on the edges, corners, and faces of packaged or unpackaged products.
-
- Pressure-sensitive adhesive labels are commonly used in cosmetic packaging. The machine tests adhesion performance, including initial tack, peel strength, and bond strength. The tensile testing machine measures peel strength by attaching the label sample to a test plate, pre-peeling the label, and then measuring the force required to peel it off.
-
Salt Spray Chamber:
- Products exposed to marine air or mist during sea transport or coastal use are prone to corrosion. The salt spray chamber tests the corrosion resistance of various materials, including coatings, electroplating, and anti-corrosion treatments.
-
- The impact resistance of packaging materials is critical to prevent surface damage during transportation. The impact tester ensures that packaging materials can withstand impact forces without breaking.
-
Thermal Chamber:
- Simulates the effects of external temperature changes on cosmetics to assess product stability.
-
Xenon Lamp Tester:
- The xenon lamp aging test chamber offers highly reproducible and comparable results, simulating different climate conditions to test aging effects on cosmetics. It helps identify product defects, chemical changes, and evaluates the safety and performance of finished products, which is crucial for ensuring product quality and safety。
