How Does a Sachet Filler & Packaging Machine Work?

Sachet filler ＆ packaging machine is a type of packaging equipment specifically designed for filling and sealing sachets or small pouches with various types of products, such as powders, granules, liquids, or pastes. This article will introduce to you how sachet filler & packaging machine work .

Working principle of sachet filler & packaging machine

Film Unwinding: The machine begins by unwinding a roll of packaging film or foil material. This film acts as the base material for creating the sachets.

Forming the Sachets: The machine passes the film through a series of rollers and forming devices that fold and seal the film, creating individual pouches or sachets. The shape and size of the sachets can be customized based on the product requirements.

Product Filling: Once the sachets are formed, the machine moves on to the filling stage. It dispenses the product into each sachet using precise dosing mechanisms. The filling system can vary depending on the product, ranging from volumetric fillers to auger fillers or liquid pumps.

Sealing the Sachets: After the filling process, the machine proceeds to seal the sachets to ensure product freshness and prevent leakage. The sealing method can be heat sealing, ultrasonic sealing, or a combination of heat and pressure, depending on the packaging material and product characteristics.

Cutting and Separating: Once sealed, the machine cuts the film between the sachets to separate them from the continuous roll. This allows for individual, ready-to-use sachets.

Quality Control and Inspection: Some sachet filler and packaging machines include quality control mechanisms to ensure proper sealing and filling. Sensors or vision systems may be used to detect any defects or inconsistencies in the sachets, enabling rejection of faulty units.

Coding and Printing: The machine may incorporate a coding or printing system to add important information on the sachets, such as expiration dates, lot numbers, or barcodes. This helps with traceability and product identification.

Collection and Packaging: Finally, the filled and sealed sachets are collected and prepared for further packaging, such as bundling, cartoning, or boxing, depending on the desired packaging format.

Sachet filler and packaging machines are widely used in various industries, including food and beverage, pharmaceuticals, cosmetics, and personal care products. They offer efficient and automated solutions for filling and packaging small, single-use sachets, ensuring product hygiene, convenience, and extended shelf life.
