Can a spout pouch be filled with a hot sauce?
Yes. Hot fill above about 85 °C needs a laminate chosen for it, so say the fill temperature on the brief and we confirm the film on the quote.

Quoted per order, from £0.25 a pouch
A stand up pouch with a plastic spout welded into the top seal and a screw cap that opens and closes again. Sized by the millilitre, printed in your colours, for anything that pours or squeezes.
The short version
Spout pouches are flexible stand up packs with a rigid plastic spout and cap fitted in the top seal or a top corner. They replace bottles for sauces, purees, honey, juice shots and hand wash refills, and fold flat when empty. We make them to your fill volume and print them with your design, confirmed on a written quote.

A spout pouch is a stand up pouch with a plastic spout welded into the top seal. A screw cap closes the spout, so the customer pours a little, caps it and puts the pack back in the cupboard or fridge.
The body is a laminate with a bottom gusset. Filled, it stands on the shelf like a small bottle. Empty, it folds flat, which is the main reason brands move across from rigid packs.
The spout can sit in the centre of the top seal or in one corner. A centre spout pours straight down and suits drinks and purees. A corner spout angles the neck, which makes pouring into a bottle or a pan cleaner.
Anything that pours or squeezes. UK sauce makers took to this format early, and bath and body refill brands followed because a pouch uses far less material than a bottle.
Our spout and retort pouch range groups the spouted styles beside the heat-processed pouches used for wet meals, so you can compare them on one page.
A 250 ml sauce pouch is often around 110 × 180 mm with a 60 mm gusset. That leaves headspace above the fill line, so the pouch can be squeezed without product rising up the neck.
Capacity comes from three numbers: width, height and gusset depth. Thick products need more headspace than thin ones because the filler leaves air behind in the pouch.
Describe the viscosity in plain words, such as runs like single cream or holds its shape on a spoon. We size the pouch and the spout from that, and our stand up pouch size guide shows the dimensions behind each fill.
Liquids work on a pouch from the inside. Acidic sauces and essential oils stress the seal layer, and oxygen passing through the film dulls colour and flavour over the months on shelf.
For long-life sauces and juices, PET / foil / PE blocks light and oxygen. Where a customer needs to see the product, clear PET / PE shows the colour and accepts a shorter shelf life.
Food-contact, high-barrier and compostable film options are available on request. Tell us the acidity, whether the product is hot-filled and the shelf life you want, and we match the structure, as explained in our guide to barrier films and laminates.
The fitting decides how the pouch is used at the table or in the bathroom. These are the common choices.
| Fitting | Typical use | Note |
|---|---|---|
| Centre top spout with screw cap | Drinks, purees, children's pouches | Pours straight; add a hang hole for pegs |
| Corner spout with screw cap | Sauces, honey, refills | Angled neck pours cleanly into a bottle |
| Flip-top cap | Squeeze sauces at the table | One hand opens it; wants a stiffer pouch wall |
| Tamper-evident band | Retail drinks and purees | Band breaks on the first twist |
| Spout plus hang hole | Refills on hooks | Keeps the pouch upright on pegboard |
The spout is welded into the top seal, so the top 20 to 25 mm of the front panel is seal area and does not carry print. Keep the logo and product name below that line.
Full colour digital print handles photographic fruit and glossy sauce shots well. On foil, a white under-print goes down first so your colours do not pick up a metallic cast.
Our designers set your artwork on the dieline and send a free proof before anything is printed. The artwork guide for printed pouches lists bleed, seal areas and the files we need.
Most small brands fill through the spout with a hand or semi-automatic filler, then screw on the cap. Larger lines fill through an open top and seal it afterwards. Either way, the routine is the same.
Choosing a neck too narrow for the product is the usual one. Chunky relish blocks an 8 mm neck, and the customer squeezes until the seal gives way.
The second is ignoring headspace. A pouch filled to the brim cannot be squeezed without product shooting up the neck when the cap comes off.
The third is running a dark design right up to the spout weld. The weld area crinkles, and dark ink shows every crease. A lighter band around the spout hides it.
Hand wash, body wash and shampoo brands sell refill pouches so customers keep the bottle and buy the liquid again. A corner spout pours into a narrow bottle neck without a funnel.
A 500 ml refill pouch is often around 150 × 230 mm with an 80 mm gusset. A matte finish and a frosted window suit the clean look most of these brands want.
Scrubs and salts are dry and want a zipper instead of a spout. Those sit on our bath salt and scrub pouches page.
Send the fill volume, what goes in, how you will fill it and roughly how many you need. Quantities are quoted per order, from £0.25 per unit, and the written quote confirms the figure.

Yes. Hot fill above about 85 °C needs a laminate chosen for it, so say the fill temperature on the brief and we confirm the film on the quote.
A 10 mm neck is a common choice for smooth purees. Thicker purees with pulp move more easily through a 16 mm neck.
A correctly welded spout holds. We proof the spout position and you can squeeze-test the first pouches on your line before running the batch.
Yes. Corner spouts suit sauces and refills that pour into another container, and centre spouts suit drinks and purees taken straight from the pouch.
Screw caps, flip-top caps, tamper-evident bands and soft choke-guard caps for children's pouches. We confirm the fitting on your quote.
Usually yes, the pouch arrives capped. If your filler needs loose caps, say so on the brief and we confirm on the quote.
Leave roughly 10 to 15 percent of the pouch above the fill line. Thick products need the larger figure so the pouch squeezes without surging.
Yes, on a clear PET / PE laminate, or with a window in a foil pouch. Clear film gives a shorter shelf life for light-sensitive liquids.
Yes, as long as the gusset is open and the product sits in the base. Very thin liquids in tall pouches can lean, so we keep the height sensible.
Yes. Refill pouches are one of the fastest growing uses, and a corner spout pours into a bottle neck cleanly.
PE seal layers tolerate the freezer, and frozen fruit pouches are common. We confirm the laminate for freezing on your quote.
Yes. A tamper band breaks on the first twist, which retailers like on drinks and purees. Ask for it on the brief.
