Flexible size: adapt to diverse commodity packaging needs
We provide two common specifications -17*30cm and 50*70cm, which can well cope with different types of package needs. Smaller sizes are ideal for small items and personal package delivery, while larger sizes are better suited for bulk cargo transportation and packaging of large items. In either case, both sizes are perfect for the task.

Through specific application cases, we can see that these different sizes show great flexibility and convenience in actual operation. For example, when an online retailer uses a small 17*30cm express bag to process daily orders, it is found that this not only improves the packaging efficiency, but also reduces the storage space occupancy rate. For logistics companies, using 50*70cm large bags to ship heavy equipment greatly improves transportation safety.
