In our production and life, color printing woven bags have a wide range of applications. In different types of applications such as rice, flour and other food packaging, feed woven bags, putty powder woven bags, etc., a large part of the packaging products will be exposed to the sun. Under the action of different environmental factors, the product quality of woven bags will be affected to varying degrees. Improve the UV resistance of the color printing woven bag, which can maintain the stability of the woven bag and improve the efficiency of use.
Relatively stable data can be obtained through artificial accelerated aging test and outdoor exposure test. The artificial accelerated aging experiment is to put the plastic woven bag test sample in the test equipment, which can be simultaneously or alternately affected by factors such as light, oxygen, heat and humidity. Under this condition, the main environmental parameters can be easily Keep relatively stable, so the data obtained can maintain good repeatability. Outdoor exposure test is to put the plastic woven bag test sample in a specific test site to be directly affected by specific climatic conditions, and the general test time is very long, several months or even years, and the data obtained is relatively in line with the use environment of the plastic woven bag. Products that have passed the test and test will have an improved UV resistance in the real use environment.
