4-Side Seal Liquid Sachet Automatic Counting and Cartoning Line
Product Overview
The 4-Side Seal Liquid Sachet Automatic Counting and Cartoning Line is designed for the secondary packaging of small liquid sachets after primary sachet packing.
This line is especially suitable for 4-side seal sachet products such as ketchup, mayonnaise, salad dressing, chili sauce, soy sauce, honey, syrup and other liquid or semi-liquid products packed in small sachets.
After the sachets are produced by the multi-lane packing machine, they are transferred by the counting conveyor, grouped according to the preset quantity, automatically dropped into cartons, and then conveyed to the carton sealing section.
This system helps reduce manual counting and manual loading while improving packing efficiency and carton quantity consistency.
