Step 1: Film Feeding

Plastic rolls (PE, PP, or other types) are fed into the machine's unwinding unit.

The roll passes through alignment guides to ensure smooth feeding.

Step 2: Film Cutting

Length Control: The machine is programmed to cut the film into specified lengths.

The film is cut using a sharp blade or rotary cutter as per the preset length.

Optional Folding: For certain bags (e.g., gusseted or T-shirt bags), the film can be folded prior to cutting.

Step 3: Heat Sealing

Positioning: The cut sheets are automatically positioned under the sealing bar.

Impulse Sealing: The sealing bar heats up and applies controlled pressure to fuse the edges of the plastic.

Sealing Patterns: Custom sealing patterns (e.g., straight or perforated seals) can be chosen based on the bag type.

Step 4: Cooling and Solidifying

After sealing, the machine applies a cooling mechanism to set the seal and prevent warping or sticking of the material.

Step 5: Optional Hole Punching/Handle Cutting

If required, a punching tool cuts out holes for handles in T-shirt bags or inserts hang holes for retail bags.

Step 6: Stacking/Batching

Finished bags are stacked in batches for further packaging or sent to additional processes (e.g., printing or perforation for rolls).

Step 7: Waste Management and Recycling

Trimmed plastic or waste material is automatically separated and collected for recycling or disposal.

Retail Packaging: Commonly used to make grocery bags, T-shirt bags, and flat bags for retail stores.
