Abstract  

Packaging has become an indispensable part of our daily lives, without which it would bring great inconvenience and insecurity to consumers. The current global trend is to reduce the amount of packaging waste by recycling the same materials or using renewable waste raw materials. After each year's corn harvest, a large amount of straw is discarded in fields, and these corn straws are becoming an alternative source for wood fibers in green packaging. This study evaluates the feasibility of using straw fibers for gravure printing packaging by observing the quality parameters of gravure printing and the ink penetration into the printing substrate. From the experimental results, it can be seen that the gravure printing ink penetrates too much into the printing substrate, resulting in uneven surface ink distribution. The viscosity of the ink and the printing process itself have a significant impact on this. Therefore, gravure printing needs to add additional coatings or more fillers in the paper structure to improve it.
