Custom Printed Vacuum Seal Pouches for Coffee and Dried Foods

What makes a vacuum seal pouch different from a flat pouch?

A standard flat pouch is built to hold product at normal pressure. A vacuum seal pouch has to hold its shape while the air is pulled out and the film collapses onto the contents.

That takes a thicker inner PE layer, usually bringing the laminate to 100 to 140 microns. The thicker layer resists pinholes from sharp coffee beans and nut edges.

The foil in the middle is what keeps the vacuum. Clear PE bags let oxygen creep back through the film over weeks; foil does not. Our foil mylar bag range uses the same barrier layer in other shapes.

Who uses vacuum sealed pouches in the UK?

Coffee roasters packing ground coffee into bricks for cafes and supermarkets. The hard brick stacks well and shows the customer that no air has reached the coffee.

Smokehouses and charcuterie makers packing sliced meats and whole pieces. Dried fruit and nut suppliers who want a 12 month shelf life without preservatives.

Brands packing lightweight freeze-dried meals often pair these with our freeze dried food bags for long storage, using the vacuum pouch for the dense items.

• Ground coffee bricks for cafes and wholesale
• Cured and smoked meats, sliced or whole
• Dried fruit, nuts and seeds
• Hard cheeses and portions for delis
• Freeze-dried meals and emergency food
• Rice, pulses and grains in catering packs

Chamber sealer or edge sealer: which pouch works?

Most food producers with a vacuum machine own a chamber unit, which suits our standard smooth pouches. Tell us which machine you run and we match the pouch to it.

What size vacuum pouch for a 250 g coffee brick?

A 250 g ground coffee brick is usually around 110 × 160 × 40 mm once pressed. The pouch needs that footprint plus 20 mm on each side and 60 mm of extra height for the seal and the vacuum draw.

That gives a pouch around 150 × 220 mm, which is why that size is so common. For 500 g go to about 180 × 280 mm and for 1 kg about 220 × 340 mm.

Hard bricks need square corners on the pouch so the film folds neatly. Roasters who also sell beans in a stand up form can match the print to our printed coffee bags for roasters.

Oxygen absorbers and nitrogen flushing

A vacuum removes most of the air, but not all. Oxygen absorber sachets, like the one in the photo above, take care of the oxygen that remains and any that creeps in at the seal.

Nitrogen flushing is the other approach. The pouch is filled with nitrogen before sealing so the product is not crushed, which suits whole bean coffee and crisps better than a hard vacuum.

Either method works with our foil laminate. If you pack coffee within days of roasting, read our coffee bag valves and degassing guide first, since fresh coffee releases gas that a vacuum pouch cannot vent.

Printing on vacuum pouches

A vacuum pouch wrinkles as it collapses, so large flat areas of colour show creases. Keep the main design in the centre of the face and avoid fine lines near the edges.

Many brands print one or two colours on a plain silver or white foil face, then add a label for the variety and date. Full colour print is available where the pouch is the retail pack.

White under-print keeps colours true on silver foil; without it a yellow logo turns olive. Our pouch artwork guide with dieline rules shows where the film will crease.

How do you vacuum seal a pouch step by step?

The steps below suit a chamber machine, which is what most small food producers run. Food-contact and high-barrier film options are available on request and confirmed on the quote before you start.

1. Fill the pouch, leaving at least 60 mm of clear film at the top.
2. Wipe the inside of the open edge so no oil, dust or coffee fines sit in the seal zone.
3. Lay the pouch flat in the chamber with the open edge over the seal bar.
4. Run the cycle at the vacuum level that suits the product, lower for soft items and full for hard bricks.
5. Check the seal is a continuous line with no bubbles or channels.
6. Let the pouch rest for an hour; a loose pouch after that means a leak.

Common vacuum pouch problems and their causes

Pouches that go soft overnight. Nearly always a seal contaminated with product, or a pinhole from a sharp bean or bone edge. A thicker laminate and a wipe of the seal zone fix both.

Film that will not seal. The machine is set for thin PE bags and not for a 120 micron foil laminate, so the seal time needs raising.

Seals that look fine but peel. Too little dwell time, or the seal bar's cover strip is worn.

Bricks with a loose corner. The pouch is too wide for the brick, so the film folds over itself and traps air. A film fault is different, and our reprint and refund terms cover it when reported within 10 days with photos.

Can vacuum pouches have a window or a tear notch?

A tear notch is sensible on retail packs, since vacuum sealed foil is tough to open. We place it just under the top seal.

A clear or frosted window suits cured meats and cheese, where buyers want to see the cut. Keep the window away from the corners, where the film stretches most under vacuum.

Zippers are not fitted to vacuum pouches. The vacuum would be lost on first opening and the zipper adds thickness in the seal area. If you want a reclosable version without vacuum, our standard three side seal pouches take a press-to-close zipper.

Getting a quote for vacuum seal pouches

Send the product, your sealer type, the fill weight or brick size, and how many you need. Prices start from £0.25 per unit, and the written quote confirms the figure for your run.

Printed pouches get a free design proof from our team first. Plain silver or white pouches skip that step. Use the short form above or the full quote request form for pouches to include a photo of your current pack.

Production is 4–6 business days after approval, with free tracked delivery to any UK address in 2–3 business days. If pouches arrive misprinted or damaged, photos sent within 10 days get a reprint or a refund.
