Description

Technical Field

[0001] The utility model belongs to the technical field of paper bags, and particularly relates to a highly permeable moisture-proof paper bag. Background Art

[0002] A moisture-proof paper bag is a paper packaging container specially designed to protect the packaged items from moisture. It combines the specific properties of paper with moisture-proof treatment technology or structural design to ensure that the penetration of external moisture into the bag is effectively isolated or reduced within a certain period of time, thereby maintaining the dry state of the items and preventing quality loss, deterioration or functional failure due to moisture.

[0003] Moisture-proof paper bags often have low air permeability due to their moisture-proof properties, which are designed to limit the entry of external moisture into the bag. However, for some items that have certain requirements for ventilation, overly closed moisture-proof paper bags may result in poor internal air circulation and lack of necessary air exchange or moisture discharge mechanisms, thus affecting the storage conditions and shelf life of the items. Therefore, we hope to design a moisture-proof paper bag with a new structure to solve this problem. Utility Model Content
