The Yiren double-wire twist-tie machine is a fully automatic bag sealing device designed specifically for efficient bread bag closing in bakery production lines. With a production speed of 30-40 bags per minute, it significantly improves packaging efficiency while ensuring consistent and professional sealing quality.
The machine adopts a double-wire twist-tie system, which delivers stronger and more reliable seals compared to traditional single-wire alternatives. The finished petal-shaped closures are aesthetically pleasing and enhance product shelf appeal. The re-closable design offers a key advantage for end consumers – they can easily open and reseal bags for convenient storage of unfinished products.
Core Technical Advantages
1. Full Servo Control + PLC Touchscreen

Common Technical Issues & Solutions
Issue 1: Loose or Insecure Twist Seals
Possible Causes: Improper clearance between the twister gripper and clamping components; insufficient heating temperature of the twist-tie material resulting in incomplete bending and forming; the bag neck not fully entering the forming slot before the twisting action begins.
Solutions: Check the clearance between the twister gripper and clamping components; verify the heating element temperature settings to ensure the twist-tie material is adequately heated; inspect the auxiliary guide slot to ensure proper closure and that the bag neck fully enters the forming slot.
Issue 2: Material Jamming or Machine Stoppage During Twisting
Possible Causes: Twist-tie material not arranged neatly in the storage trough; insufficient pusher stroke or unstable air pressure; foreign matter or debris blocking the guide block.
Solutions: Check that twist-tie material is arranged neatly in the storage trough; verify pusher cylinder air pressure and pusher stroke; regularly clean dust and debris from the guide block.
Issue 3: Extended Changeover Time
Solutions: Utilize the PLC recipe memory function to pre-store parameters for different specifications and recall them with one touch during changeover; establish standardized changeover procedures to reduce trial-and-error time.
