What factors affect the waterproofness and moisture-proofness of plastic storage boxes

As an indispensable storage solution in modern life, plastic storage boxes play an important role in water and moisture resistance. However, its water resistance and moisture resistance do not entirely depend on the plastic material itself, but are affected by many factors.

Plastic material selection and quality:

First of all, the waterproof and moisture-proof properties of plastic storage boxes are affected by the selected plastic material. Different types of plastic materials have different properties, such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), etc. Generally speaking, polyethylene and polypropylene are common plastic storage box materials. They have good water and moisture resistance, but PVC may be slightly inferior in this regard. In addition, the quality of the plastic material will also affect its waterproof and moisture-proof properties. Choosing high-quality plastic materials can improve the waterproof and moisture-proof properties of the storage box.

Manufacturing process and sealing performance:

The manufacturing process and sealing performance of plastic storage boxes also have an important impact on their waterproof and moisture-proof properties. The quality of the manufacturing process directly affects the structural integrity and sealing performance of the storage box, such as welding process, mold design, etc. If the manufacturing process is not in place or the sealing is not tight, it is easy to cause water leakage or water seepage in the storage box, reducing its waterproof and moisture-proof properties.

Appearance design and structural features:

The appearance design and structural characteristics of the storage box will also affect its waterproof and moisture-proof properties. Generally speaking, closed storage boxes are more waterproof and moisture-proof than open storage boxes because the closed structure can effectively prevent the entry of water and moisture. In addition, factors such as the edge sealing of the storage box, lid design, and seam treatment will also affect its waterproofness and moisture resistance.
