4-Side Seal Sachet
Four sealed edges —
and a square face for the artwork
About this format
The difference from a 3-side seal pouch
A 3-side seal pouch is one film folded at the base. A 4-side seal sachet is two films sealed on every edge. That extra seal buys a squarer face for the artwork and a base that does not bulge — it costs a little more film per pouch. Both accept a tear notch or a zipper without changing shape.
Prints like a page
No fold across the face, so artwork lands flat and square.

What it is made of
Who fills a 4-side seal sachet
Powders and liquids that go out one serving at a time, on lines that already run flat film.
01
Batter mixes
Dry, dusty, filled at speed. The notch has to tear clean with one hand.
All
All industries
The regulars are on this ring. The full list is longer.
02
Drip coffee & tea
One brew per sachet, and a square face wide enough for the roast date.
03
Agriculture & dry goods
Sold by the kilo, stacked on a pallet, left outside longer than anyone plans.
04
Pet food
Fat and weight, in one pack. It has to hold the load and not let the oil through.
05
Pharma & supplements
The sachet is part of the stability file, and the structure answers to it.
Questions
What buyers ask before they order
- What can be fitted to the pouch?
Plain zipper, pocket zipper, one-way degassing valve for coffee, spout and cap, lipstick cap, die-cut shapes and carry handles, a clear window, matt or gloss varnish, and a clear front with an aluminium-foil back.
- Can we see a sample before the real run?
Yes. Once the quoted price is agreed we produce a sample for you to test, so both sides are sure before the line starts.
- How long does production take?
Counted from the purchase order and an approved paper proof: an ordinary film spec takes 20 to 45 days, and a repeat run takes 14 to 25 days. Reserving the material in advance can be quicker. A special spec takes 60 days or more, and we tell you which one yours is before you commit.
