[0001] The invention relates to the technical field of film testing, and in particular discloses a multi-parameter testing system for PETG environmentally friendly decorative film. Background Art

[0002] PETG environmentally friendly decorative film is widely used in food packaging, baby products and other fields due to its excellent properties such as safety, environmental protection, oil resistance, temperature resistance, scratch resistance and anti-fouling. With the increasing attention paid to industrial technology in the home improvement industry, PETG film has begun to be widely used in the home improvement field, such as wall panels, cabinets and other home furnishings, because of its far superior properties to other material films. This application trend has prompted the market to put forward higher requirements for the performance of PETG environmentally friendly decorative film, including wear resistance and aging resistance.

[0003] In order to ensure that PETG environmentally friendly decorative film can meet the high standards of the market, it must be subjected to comprehensive performance testing. Traditional testing methods can only test a single parameter and cannot meet the needs of simultaneous testing of multiple parameters, which leads to low test efficiency and difficulty in fully reflecting the comprehensive performance of the material. Therefore, it is particularly important to develop a system that can simultaneously test multiple key parameters of PETG environmentally friendly decorative film. Summary of the invention
