What customers say

Relationships measured in years, not shipments

We visited the UnisunPack factory and were impressed with the equipment and the clean workshops. The bags are consistently lower in price than other factories in China, and the quality is good.

During the whole purchasing process UnisunPack made me feel very safe — from sample testing to bulk production, shipment and customs clearance. A reliable supplier.

I have worked with UnisunPack for four years. The quality is high and my retailers have never complained. All I have to do is wait to receive the goods for each order.
