The moisture-proof performance of the effervescent tube is mainly reflected in the following aspects:
Desiccant on the lid: A desiccant is usually placed on the lid. This desiccant is generally made of silica gel and molecular sieves mixed in equal proportions. Silica gel can effectively control the number of water molecules in the long term, while molecular sieves can quickly absorb water molecules in a short period of time. This design can effectively absorb internal moisture and prevent effervescent tablets from deteriorating due to moisture.
Barrier properties of the tube material: The material of the effervescent tube body is usually made of polypropylene. This raw material itself has good barrier properties and can effectively block the intrusion of external water molecules, thereby further protecting the internal effervescence. film to improve its moisture-proof performance.
Dryness of cardboard seal: The desiccant compartment in the lid is generally sealed with white cardboard, which is beneficial to maintaining the moisture-proof performance of the desiccant. If the cardboard is too thick, it may increase the barrier effect on the desiccant, thus affecting its moisture-proof performance. If the moisture content of the cardboard is too high, the desiccant will apply more moisture absorption properties to the cardboard, reducing the overall moisture resistance of the internal environment of the packaging.
In general, the moisture-proof performance of the effervescent tube is mainly achieved through the desiccant on the cover and the barrier properties of the tube material. In actual use, we also need to pay attention to the overall sealing of the packaging to prevent the effervescent tablets from getting damp and deteriorating.
