Brief Introduction

Plastic films physical properties are significant for material research and development, applications and design. For enterprise quality control departments and quality inspection institutions, plastic films physical properties are frequently tested items, and test result accuracy is always a concern.

Proficiency service is an important way to improve a laboratory’s testing capability and proficiency, it also helps a laboratory to identify its problems and verify the accuracy of the testing instruments. Since 2014, Labthink has successfully organized 5 times of proficiency service.
