[0002] Packaging bags are essential items in daily life, used to carry items. They are made of paper, plastic, or a combination of these materials. However, existing packaging bags have structural shortcomings: due to poor design, most are quite flexible. Therefore, when easily damaged or broken items (such as elaborately made cakes or glass jars) are placed inside, they cannot provide adequate protection if the bag accidentally bumps into a hard object like a wall while being carried. This can easily lead to the items inside the bag colliding directly with the object, causing damage.

[0003] In addition, the bottom of existing packaging bags is prone to tearing, resulting in a short lifespan and poor practicality. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a puncture-resistant and impact-resistant packaging bag with reasonable structural design, good protective effect, easy to protect the contents of the bag, easy to prevent the bottom from breaking, long service life and good practicality.
