Filling a sachet bag involves a few key steps, whether you're doing it by hand or using a machine. Manually, you'll want to use a funnel to help guide the sachet filling (about ½ cup) into the bag, then gather the top edge and tie it securely with a ribbon or twine. If you're using a machine, it automates the process, including unwinding the packing material, forming the sachet, feeding and filling the product, heat sealing, and even printing batch numbers before cutting and delivering the final product. Each method has its advantages, depending on the scale and precision you need for your sachet-making operation.
Key Points Explained:
-
Manual Filling:
- Measurement: Start by measuring approximately ½ cup of your sachet filling material. This ensures a consistent amount in each bag.
- Funnel Usage: Employ a funnel to guide the sachet filling into the bag. The funnel helps to prevent spillage and ensures that the filling goes directly into the sachet bag, keeping the bag clean.
- Securing the Bag: Once filled, gather the top edge of the sachet bag. Use a narrow ribbon, cord, or twine to tie the bag securely. Knot it firmly to prevent any of the contents from spilling out.
-
Automated Filling (Machine Process):
- Packing Material Unwinding: The machine starts by unwinding the packing material from a roll. This ensures a continuous supply of material for creating the sachet bags.
- Sachet Forming: The machine then forms the sachet bag from the unwound material. This involves cutting and shaping the material into the desired sachet size and shape.
- Product Feeding and Filling: The product to be filled is fed into the machine, which then accurately fills each sachet bag with the correct amount.
- Sachet Heat Sealing: After filling, the machine heat seals the sachet bag to close it securely. Heat sealing ensures an airtight and tamper-proof closure.
- Batch Number Embossing or Printing: The machine can also emboss or print batch numbers on the sachet bags. This is important for tracking and quality control purposes.
- Cutting and Final Product Output: Finally, the machine cuts the individual sachet bags from the continuous strip of material and outputs the final product. This completes the automated sachet filling process.
