Product Detail

With the improvement of people's living standards, consumers have higher demands on the quality of food, clothing, food, beverages, medicines, automobiles and other products, because the quality of their products is closely related to people's lives. It has become the focus of attention of many enterprises and consumers. Among them, material quality control is an important aspect of product quality. In order to make material suppliers have a clear understanding of the quality of their own products, Guangzhou Standard International provides sample commissioned testing services to the community.



Coefficient of Friction. ASTM D1894 is a testing standard designed to measure the friction of plastic film and sheeting. This test method measures the initial and moving friction of one material being dragged across another, otherwise known as the static (initial) and kinetic (moving) coefficients of friction (COF).



GBPI GM-4 Coefficient of Friction Tester is used to test the smoothness, evenness and sealing strength of plastic film, paper and other materials, used in packaging industry, membrane industry, inspection agency and so on.


1. Core part is imported, with high performance, stability and accuracy, and durable.

2. Easy to operate, software controlled, can connect to computer and display curves and print report.

3. Infinitely variable speeds setting.

 Leak Test Equipment 2022 High Quality Machines Package Leak Test Equipment

Test Principle
Firstly submerge the specimen in the water in the vacuum chamber, and then evacuate the vacuum chamber to form differential
pressure between the inside and outside of specimen. The seal property can be obtained by observing the steady progression of
bubbles from the specimen or observing how the specimen expands and restores to its original shape after vacuum release.

Professional Vertical Heat Seal Tester GBB-C supplier Vertical Heat Seal Tester GBB-C

Product Introduction

GBB-C vertical heat seal tester can accurately measure the heat sealing temperature, heat sealing time, heat sealing pressure, and other heat sealing performance parameters of plastic packaging vertical bags, paper-plastic composite vertical bags and metal composite vertical bags(boxes). The heat sealing performance of samples of different materials are different. And the best heat sealing conditions can be accurately obtained through the determination of their heat sealing performance parameters.

 

Testing Principle

Put the sample on the lower tray of the instrument, adjust the appropriate height according to the size of the sample, set a certain sealing temperature, time and pressure as required, and start the instrument with one key. The fixture on the instrument will heat seal the sample according to the setting parameters. Under the manual state, step on the foot switch, and the heat sealing knife is pressed. The heat sealing time is determined by the value set by the time control. In the automatic state, the upper and lower heat sealing knives of the heat sealer will automatically heat seal repeatedly according to the set time.
