How 25um Bags Support Efficient Packaging+

The 25um thickness provides the most economical option in the LDPE range. For applications where contents are lightweight and puncture resistance is not critical, this thickness delivers cost savings without sacrificing basic protection. The soft, flexible material conforms easily around products and opens readily for fast filling.

Clear LDPE allows visual identification of contents without opening bags, speeding up inventory management and picking operations. Staff can quickly locate specific items in storage bins or confirm pack contents at shipping stations. This visibility reduces errors and handling time.

High pack quantities of 1,000 to 2,000 bags per carton support high-volume operations. Workstations stay stocked longer between replenishments, and bulk purchasing reduces per-unit costs. The compact carton sizes fit standard shelving and storage systems.

When to Choose a Heavier Thickness+

Consider 35um or 50um bags when packaging items with sharp edges, heavier weights, or when bags will undergo significant handling during transport. Heavier thicknesses provide better puncture resistance and durability for demanding applications. The 25um option works best for lightweight, smooth items where economy is the priority.
