The bonding strength between the collector and the active substance may encounter some problems during charging and discharging processes. Labthink laboratory right has the experiences in test of the bond strength of collector electrode. Recently we arranged such a test for Li-ion battery electrode Continue reading
Thermal shrinking performance is one important property of plastic film. Three thermal shrinkage test methods of plastic film are introduced in this article i.e. oil bath method, drying oven method and air heating method. This article provides a comparative analysis on the three test methods of thermal shrinkage of film. Continue reading
A suitable thickness of packaging film not only increases the barrier performance of packaging materials, but also effects the seal quality of packaging, for the improvement objects, when you performance oxygen transmission, water vapor transmission or heat seal measurement, we suggested you measure the thickness, which also affects your decision of your packaging improvement.
