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.
