A pulp-molded packaging article is introduced herein, which comprises a bottom wall, and a standing lateral wall having a bulge region and a groove region. A transversely cross-sectional thickness located at the bulge region is larger than a transversely cross-sectional thickness located at the groove region. While a to-be-packaged object enters inside the article to oppress the bulge region, the bulge region is therefore actuated in elastic deformation to reach an outwardly deflected position. And then, after the to-be-packaged object continues to reach the groove region, the bulge region is rebounded therefore to exert reverse elastic forces on the to-be-packaged object, resulting in a snap-in retention onto the to-be-packaged object, which makes the snap-in convex surface stopping the to-be-packaged object from moving toward a top opening of the article.
