Vertical form-fill-seal machines
A vertical form-fill-seal machine makes the bag from a roll of film, fills it and seals it. A premade pouch machine starts from a finished bag. The reference page for this line is Soontrue’s ZL180 liquid vertical packing machine.
That page lists oil, detergent, juice, milk, honey, soy sauce, ketchup and tomato sauce. A fill weight or fill volume is not printed in the parameter table, so none is shown. The dosing unit photographed on the page carries a 1,000 ml label; that label is not used here as the machine’s fill range.
Soontrue’s wider catalogue also includes vertical machines for granules and powders. Those dosing styles are a discussion point. They are not assigned to the four models below.
Figures on this page are copied from the Soontrue pages linked below. They are manufacturer webpage claims, not a rate we guarantee on your product. Options discussed here are topics for the quotation, not a statement that every item is on the standard machine. Warranty terms are not stated on this site because Soontrue’s own pages do not agree.

What we need to discuss
- Liquid viscosity, temperature and whether the product is corrosive or needs a specific contact material.
- Film structure, thickness and the bag style you want.
- How filled bags leave the machine and what the downstream case or carton expects.
Questions we hear
How is this different from a premade pouch machine?
Vertical form-fill-seal forms the bag from roll film. A premade pouch machine opens, fills and seals bags made in advance.
Which film can we use?
Send the film structure, thickness and bag format. Sealing has to be confirmed on that film.
Can it handle a corrosive product?
Send the material specification and the cleaning requirement so contact materials can be reviewed.
