We ordered 3 units of SBF-350 for our facial mask and food pouch lines. Installation took 2 days with Xuanhai's remote video guidance. Running consistently at 97 pcs/min. Seal quality on the aluminum foil bags is excellent — zero leakage reported after 4 months of production.

Best value-for-money three-side seal machine we have sourced from China. After 8 months of daily production (two shifts), still running at 95 pcs/min. Spare parts were shipped within 48 hours when we needed a replacement knife set. Highly recommend for LDPE and CPP pouch production.

★★★★☆
Machine arrived well-packaged, no damage. Setup video from Xuanhai team was clear. We produce laminated pouches for sachet water and snacks — the machine handles both films well. Deducted one star only because initial delivery took slightly longer than estimated. Overall very satisfied.
