Introduction

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 12 times of proficiency service. More than 1400 laboratories worldwide has participated in this event, including national quality inspection institutions, enterprises and governmental institutions, scientific research institutes and international laboratories.

Our Mission

This event aims to help the laboratories to identify the problems during the plastic films physical properties tests, monitor laboratories test procedures and improve testing instrument proficiency, in hope of continuously improving laboratories ability and narrowing the test results difference among laboratories, providing reference to the quality inspection institutions, laboratories and plastic film manufacturers.
