The machine is Three side sealing Plastic Bag Making Machinery,which suitable for BOPP,CPP,PET,PVC and nylon and other aluminized composite film and Paper-plastic composite film,the new sealing device. The whole machine runs smoothly with low noise, and adopts PLC double servo traction control, so that the materials on the discharge and overhead are continuously pulled forward by the third traction motor at constant speed. The temperature is centrally controlled by computer, reducing electricity consumption.

1. Feeding of Raw Material

• Plastic Film Roll Loading: The process begins by loading a roll of plastic film (such as polyethylene or polypropylene) onto the machine. The film can be made from virgin plastic or recycled materials.
• Automatic Film Feeding: The machine automatically feeds the plastic film into the processing section through a series of rollers that ensure smooth and tension-controlled feeding.

2. Printing (Optional)

• Printing Section (Flexographic or Gravure): Some machines include a printing unit where logos, designs, or information (such as branding or recycling instructions) are printed on the plastic film. This can be done in single or multi-color formats depending on the design requirements.
• Drying: After printing, the ink is dried using heated rollers or air dryers before moving on to the next stage.

3. Folding (Optional)

• Center Folding Unit: If the bag design requires folding, such as for T-shirt bags, the film is folded into half or other configurations using a series of mechanical guides and rollers.
• Side Gusseting (Optional): Some machines create side gussets in the film, which are folds added to the sides of the plastic to allow for expanded volume once the bag is filled.

4. Bag Sealing

• Heat Sealing: The machine creates bag seals using heat sealing bars. These bars press the plastic film together under heat, bonding the layers of the film at specific points, such as the bottom or sides of the bag.
• Cutting and Sealing in One Step: In many machines, sealing and cutting occur in the same step, ensuring that each bag is sealed and cut simultaneously at the correct length.
• Adjustable Sealing: The temperature and pressure of the heat sealers can be adjusted depending on the type of plastic being used to ensure strong, durable seals.

5. Bag Cutting

• Bag Length Control: The length of the bag is controlled by a sensor or PLC (Programmable Logic Controller), which ensures that the bag is cut to the desired size.
• Perforation Cutting (Optional): For roll-type bags, like garbage bags, perforation cutting is applied so that individual bags can be easily torn off a roll.
• Handle Cutting (T-shirt Bags): For T-shirt bags, the machine uses a die-cutting mechanism to cut out the bag handles in the correct shape.

The small plastic bag making machine is versatile and applicable across a wide range of industries, including

1. Retail and Grocery Stores

   • Produces shopping bags (T-shirt bags) commonly used in supermarkets and stores.

2. Garbage Bag Production

   • Used for producing garbage bags, especially roll-type bags with perforations, making them easy to tear and use.

3. Food Packaging

   • Creates flat bags for packaging snacks, produce, or frozen items.

4. Pharmaceuticals and Medical

   • Produces medical disposal bags, often used for hazardous waste or bio-disposables.

5. Textile Industry

   • Used for making protective packaging bags for garments, such as dry-cleaning covers.

6. Agriculture:

   • For produce bags that are used for fresh vegetables and fruits in local markets and grocery stores.
