Vacuum Pouches vs Vacuum Rolls: Why Chamber Machines Use Bags

Vacuum Pouches vs Vacuum Rolls: Why Chamber Machines Use Bags

Vacuum rolls get searched for more than almost anything else in this category, and we don't sell them. The reason is worth a page, because it's the same reason chamber machine owners stop buying rolls once they've done the sums.

What a roll is

A vacuum roll is a continuous tube of embossed film, usually 200mm to 300mm wide, on a reel. You cut a length, seal one end, fill it, then vacuum and seal the other end. It exists because edge sealers need embossed film and because a roll lets a household make any length of bag from one reel.

Chamber machines don't need embossed film, and a business doesn't need infinite lengths; it needs the same twelve sizes every day. So the format that suits a chamber machine is the pre-made pouch: smooth film, three sides sealed at the factory, one cycle on the machine.

What a roll actually costs per bag

A roll looks cheap because the price is per reel, not per bag. Work it back:

Embossed roll Pre-made smooth pouch
Typical price £12 to £20 for a 280mm × 10m roll £27.00 for 1,000 × 200×300mm
Bags per unit About 30 at 300mm each, fewer with waste 1,000
Cost per bag 40p to 65p 2.7p
Cycles per bag Two (seal, then vacuum and seal) One
Cutting and measuring Every bag None
Seals per bag that can fail Two One

Even a good trade price on rolls lands at 15p to 25p a bag. Against 2.7p for a pre-made pouch, a business packing 50 items a day is spending £1,500 to £3,000 a year more on rolls than it needs to, plus the time. And the first seal, the one you made yourself on the roll, is where most leaks start.

The "any length" argument

The one thing a roll does that a box of pouches can't is make a 900mm bag on the spot. In practice almost nothing needs that. Our range goes to 350×750mm and 530×650mm, which cover whole sides of salmon and full beef primals. For long, narrow product there's the 240×650mm. The size index lists all 37 clear sizes, and a genuinely odd size in volume is a bespoke order.

A long pouch that won't fit the chamber is sealed in two passes, which is still fewer seals than a roll.

When a roll is still the right buy

If you have an edge sealer and no plans to change it, a roll is the correct product, from the machine's maker or a general supplier. Our pouches won't seal in an edge sealer at all; the FoodSaver guide explains why. The chamber vs edge sealer guide sets out when the machine is worth upgrading.

Switching from rolls to pouches

If you've been running rolls through a chamber machine, the switch is two boxes. Measure the bags you cut most often, round the width up to the next size in the index, and order those. Most people find they were cutting roughly 200×300mm and 300×400mm bags all along. The embossed vs smooth guide covers the film difference if your team is used to the textured feel.

Questions we get asked

Do you sell vacuum rolls?

No. We make pre-made pouches in 47 sizes and finishes for chamber machines. Rolls are an edge sealer product.

Can I use a roll in a chamber machine?

You can cut a length, seal one end, fill it and seal the other. It works, but it's two cycles per bag, the roll is usually embossed and costs more per metre, and the first seal is where leaks start. A pre-made pouch is one cycle and one seal.

What if I need a size you don't make?

For an unusual length, use the next size up or one of the long formats. For a genuinely odd size in volume, we make bespoke pouches to order.
