The production technology :
Material Handling: The process starts with the handling of raw materials, typically rolls of plastic film made from materials like polyethylene (PE) or polypropylene (PP). These rolls are loaded onto the machine's material feeding system.
Zipper Attachment: Specialized mechanisms are used to attach the zipper to the plastic film. This involves precise positioning of the zipper tape and secure sealing to create the zip lock feature. Depending on the machine design, zipper attachment may be done before or after the film is formed into bags.
Bag Forming: The plastic film is then fed through a series of rollers and folding mechanisms to form it into the desired bag shape. This may involve folding, sealing, and cutting the film to create individual bags.
Filling and Sealing: If the bags are intended for packaging products, an automated filling system is used to dispense the product into each bag. The bags are then sealed using heat sealing, ultrasonic sealing, or other sealing methods to ensure product freshness and prevent leakage.
Optional Features: Some machines may include optional features such as printing units for adding branding or product information, handle attachment mechanisms, tear notches, or gas flushing systems for modified atmosphere packaging (MAP).
Control Systems: Advanced control systems, often utilizing Programmable Logic Controllers (PLCs) or computerized control panels, regulate the machine's operation, ensuring precise control over parameters such as bag dimensions, sealing temperature, and production speed.
Safety Features: Safety mechanisms such as emergency stop buttons, safety guards, and sensors are integrated into the machine to ensure operator safety during operation.
Maintenance and Quality Control: Regular maintenance, including cleaning, lubrication, and inspection of machine components, is essential to ensure smooth operation and prevent downtime. Quality control measures are also implemented to ensure that produced zip lock bags meet strict quality standards in terms of dimensions, seal strength, printing accuracy, and overall integrity.
