The Need to Test Overall Barrier Property of Package
|
From Labthink Instruments Co., Ltd
Abstract: This article briefs on the current conditions of package barrier property testing. Based on field test data, the need to test overall barrier property of package is analyzed. Liquid is mainly packaged in containers. Except for metal cans and packing box of pulp-molded aluminum, one complete package mainly consists of bottle body and bottle cap, with the former usually being made of glass and plastic and the latter being made of metal and plastic. Since barrier property of the package can directly influence quality guarantee period of its inner content, how to improve barrier property of bottle body and how to improve barrier property and sealability of bottle cap become focal point of current package manufacturing. In fact, the connecting point of bottle body and bottle cap is a key factor that influences overall barrier property of package. Products & Services

Schottky diodes in their simplest form consist of a metal layer that contacts a semiconductor element. The metal / semiconductor junctions exhibit rectifying behavior (i.e., the current passes through the structure more readily with one polarity than the other).
