Liquid and paste fill into premade pouches one of two ways: through the open top and then a heat seal, or through the spout and then a cap. Which way depends on the pouch as much as the product. So we start every liquid review with a pouch sample and a description of what goes in it.

Product and Viscosity Range

"Liquid" covers a lot. Water-thin drinks, detergent, edible oil, sauce and fruit concentrate all behave differently at the filling head. The LV-210 listing names juice, jelly, concentrated juice and functional drinks. The LV-160 listing names laundry liquid, cleaner, dish soap, disinfectant, beer, tea drinks, edible oil and water. Sauce has its own listing, covered on the sauce pouch filling page.

The catalog doesn't give a viscosity range or temperature limit for any listing, so we work from what you tell us. Send us:

What to sendWhy we ask
Viscosity at fill temperaturePoints to pump type and nozzle size
Fill temperatureChanges flow, steam and the seal zone
FoamingFoam shifts the level and can reach the seal
Particles or pulp, and their sizeSets the smallest nozzle and valve opening
Fill entryOpen top or through the spout
ClosureHeat seal, or cap type and spout diameter
Fill amount per pouchFixes dosing size and headspace

These are details you provide. They aren't capabilities we promise up front, and a result with one product doesn't carry over to another.

Open-Top or Through-Spout Filling

A pouch having a spout doesn't mean it's filled through the spout. Some spout pouches are filled through the open top and sealed before the spout is capped. Others are filled through the fitment itself. The two routes need different machines and different checks.

Closing stepFinal sealCap feeding and screwing
Watch forDrips, splashes, product in the seal zoneFilling head match, spout cleanliness, cap type

Use the table to pick a route, not as a list of what we offer. A pouch feeder, a liquid pump and a spout capper are separate pieces of equipment until engineering confirms the project. The pouch specifications guide lists the dimensions we ask for.

Dosing and Nozzle Options

The dosing method follows the product. Our catalog wording says sauces and drinks use a pump, powders use an auger and solids are weighed above the station. For liquids that means a pump or similar volumetric method feeding a nozzle. The sauce listing names a servo piston pump and an anti-drip nozzle. The LV-210 beverage listing doesn't say what doses the product, so we confirm that in the quotation.

When you look at nozzles, ask:

  • Does the product drip or string when the nozzle lifts away?
  • Does the nozzle have to enter the pouch mouth, and how wide is the mouth?
  • Do particles need to pass through the valve?
  • Does the head have to match a spout inner diameter?

No filling accuracy is published for any premade-pouch configuration. If tolerance matters, agree on the measuring method and range before testing. The filling accuracy guide shows what to define.

Sealing or Capping

The closing step is part of the machine scope, so raise it in the first conversation.

  • Heat sealing: keep the liquid level clear of the seal zone, and check seal quality on a trial with your own film.
  • Capping: the LV-160 listing includes automatic cap feeding and screwing. Confirm cap type and spout diameter, because caps that look alike aren't always the same.

Not sure which route your pouch needs? Send a photo and the dimensions of a few spare pouches. The stand-up pouch compatibility page compares open-top, zipper and spout formats.

Product Trial Requirements

For liquids and pastes, the next step is usually a sample review. Please don't ship anything until we confirm the quantity and where to send it. Plan on:

  1. Production-batch product, not a lab prototype.
  2. The pouches or spouts you'll actually use.
  3. A safety data sheet if the product is hazardous.
  4. An agreed way to measure fill amount and seal quality.
  5. The temperature and viscosity at which you fill.

A test record lists the product, pouch, configuration, settings and what we observed. How a trial fits your project is settled in the review. See the sample testing page.

Request a Review

Send the product, the pouch and the fill amount, and we'll tell you which route and listing look closest. Pricing comes in the quotation, and the price guide explains what drives it. Still comparing machine types? Start with the how to choose guide.

Frequently Asked Questions

Can one machine fill both liquids and pastes?

It depends on the configuration. The sauce and beverage listings are separate entries with different dosing equipment, so we confirm the method for your product.

Is a pouch with a spout filled through the spout?

Not necessarily. Many are filled through the open top. Confirm the route with us before you choose a machine.

Do you publish viscosity limits?

No. You tell us viscosity and temperature, and we agree a suitable configuration after review.
