In April 2022, a daily chemical products manufacturer in the United States contacted Sywen Packaging. One of their hand sanitizers added portable packaging, so they planned to purchase an automatic small liquid pouch packing machine.


  • Product: viscous shampoo
  • Packaging: printed plastic laminated packaging roll film
  • Sachet Type: four-side seal, bag width 5.5 cm x bag length 6.8 cm
  • Batch Number Coding Type: ribbon batch coding
  • Packaging Speed: 40-45 bags/min
  • Filling Specification: 6 ML/sachet
  • Filling Accuracy: ±1%


The sealing quality of the sealing of the packaging bag directly affects the customer’s first impression of the product, so the customer requires that the sealing of the sachet must be smooth and beautiful, without burrs. The sealing temperature can be adjustable, because they may change the packaging material of different thicknesses without changing the small sachet size and type.


We recommended the SY-280 automatic liquid pouch packing machine to the client. The machine adopts a 304 stainless steel piston pump as a metering device, ensuring the filling speed and accuracy are high.

The machine will be equipped with piston pumps of different volumes according to the customer’s packaging specifications, it is widely used in filling and sealing viscous and highly viscous liquids, such as ketchup, salad dressing, peanut butter, shampoo, lotion, laundry detergent, and other products.

A servo motor drives the packaging film conveying system, which can ensure the sachet-making is tidy and beautiful. The horizontal sealing and longitudinal sealing components of the sachet are made of high-quality copper, with stable thermal conductivity, and firm, and beautiful sealing.

The thickness of the packaging film is 0.04-0.08mm. The liquid pouch filling machine can be equipped with ribbon batch coding or inkjet batch coding machine according to the customer’s requirements.
