Sauce Sachet Filling & Sealing Machine

Portion sauces into film-formed sachets

A sauce sachet filling and sealing machine doses product and forms the package from film in the same run. It pulls film through, forms the sachet, delivers the sauce, finishes the seal and cuts. Ketchup and similar pumpable condiments are a good starting point for this machine family. Both the product path and the packaging tooling need reviewing against your actual recipe and portion, not a generic sauce.

Start with the finished sachet drawing, film spec and a description of your product. Name the actual seal format; don't lump every small flexible pack into one construction. This page covers a sachet machine family, not one model, lane count or output figure that fits every recipe. Those specifics come after we've reviewed your product and pack, and they belong in the written machine spec.

Supply the sauce under representative conditions

The hopper and transfer setup deliver sauce to the metering unit. Tell us how the sauce reaches that hopper, its normal filling temperature, and how long it might sit there. Note any separation, settling or change in consistency during a pause. That's what tells us whether you need a supply option at all, and what it needs to do.

If heating or agitation comes up, explain what it's for and the limits your product can tolerate. The hopper and hose photo gives a useful picture of this part of the process, but the final contact path still needs confirming. Cover refill and drainage too. A dosing trial tells you more when the sauce supply looks like the one you'll actually run in production.

Review the piston, valve and nozzle together

Piston metering is one route for this sauce machine family, and it works together with the valve and outlet, not on its own. Talk through the portion range, how it's adjusted and which product-contact parts come with the setup. If your portion is specified by weight, agree how you'll measure finished output.

Watch cutoff during sample filling. A portion can hit the right weight and still leave a tail or residue near the sachet opening. Ask how nozzle position and timing get checked against that. If your sauce has pieces in it, give their size and what condition they need to be in after filling. Test the full path with your actual recipe; don't pick an outlet from viscosity alone.

Specify the film and the four-side package

A four-side-seal sachet is sealed along all four edges, so the seal layout, the portion and the finished dimensions all have to fit inside one perimeter. Give us a drawing showing the usable product space, artwork and opening feature. Add film structure and print-repeat details from your packaging supplier. If you need a different seal format, say so as a separate tooling request; it isn't covered by the same setup automatically.

Look at how the film gets presented, aligned and cut in the proposed setup. During a trial, check print position, overall dimensions and how the seal areas look. Even a small change to the pack layout can touch tooling or setup, so keep the drawing revision attached to every discussion. The proposal should name the actual formats included, not a generic range.

Keep sauce delivery clear of the closing region

Delivery and closure have to work in step with each other. Watch the nozzle position and the film as each dose finishes. Note any splashes, trailing sauce or pieces near the sealing area. That's what points to the next adjustment or tooling question, and it belongs alongside your quantity readings, not apart from them.

Agree your finished-sachet checks before the run starts: cleanliness, seal appearance, cut position, maybe a leak check, depending on what matters for your product. Use your actual sauce and film wherever you can. A neat-looking sample is encouraging, but it doesn't prove a different recipe or film will behave the same way in production.

Make recipe and portion changes practical

List the sauces and portions you plan to run, including whichever one runs most often. Note the differences between them: flow, particles, color, residue. Ask which dosing or contact parts need to change between recipes. Include the matching sachet drawings too, so we can tell a product adjustment apart from a packaging-format change.

Talk through access to the hopper, valve, metering parts and outlet for cleaning and inspection. Your cleaning routine and the utilities available at your site affect that access, so include them. A full changeover plan covers clearing out product and film, reassembly, and checking the first good sachets. Flag which parts and settings need documenting so your team can get back to the reviewed setup after cleaning or maintenance.

Define output, coding and collection requirements

Decide whether the machine stops at sachet discharge or also handles coding, inspection and collection. Tell us what happens next and whether packs need a specific orientation or grouping. If multiple lanes are on the table, ask how total output gets counted and how you'd trace a sample back to its lane. Keep optional functions spelled out in the quotation; don't assume they're automatically included.

Describe performance together with the product, portion, film, layout and run conditions you actually used, not as a standalone number. Include any refills or stops that happened during the run. A useful trial counts the good sachets and notes why any were rejected. That gives you a much better basis for comparing setups than a maximum speed figure with no recipe or packaging attached to it.

Prepare the materials for a focused assessment

Send the full sauce description, filling temperature, portion and unit, sachet drawing, film details and the output you need. If your recipe has pieces, give their maximum size and concentration. Tell us about any cutoff, dripping or sealing problem you've already seen with your current process. That's what lets us design a trial around a specific question instead of a generic sauce.

Decide the seal format early, and tell us whether the recipe contains pieces. Both affect which tooling is reviewed, while other questions can wait. With your sachet drawing and a sample of the sauce, we can go through the run from hopper to finished pack and list what still needs confirming.
