About the B-Vac Black Vacuum Seal Rolls (120 Microns)
B-Vac black rolls
Cut your own length, keep the black finish
The cut-to-length version of the B-Vac black bags: the same 120-micron Swiss-made film, structured black on one side and smooth clear on the other, on a roll, so you set the length for each product.

How it works
From roll to bag
- 01
Choose the width
20cm for narrower products, 30cm for wider ones.
- 02
Cut the length
To the product, not a fixed bag size.
- 03
Seal one end
That makes your custom-length bag.
- 04
Vacuum and seal
Load the product and seal the open end.
B-Vac bags
Quicker for one size
16×25, 20×30, 25×35 and 25×40cm: fastest when you pack the same size again and again.
B-Vac rolls
Flexible for every length
The same black film when your products vary in length.
Why black
Presentation, with light protection on one side
The black side gives the finished pack a clean, premium look for retail display, gift packs and artisan products, and blocks light to one face for products that fade under light in longer storage. The clear side still shows the contents. Thicker than a standard 90-micron clear roll such as the E-Vac.
Which width
| Width | For |

| 20cm | Sausages, single portions, narrower cuts |
| 30cm | Whole fish, larger cuts, wider products |
Best for

- 3Applied automaticallyNo code needed. Your cart shows the saving.
Example: 4 packs of R-Vac bags + 2 packs of E-Vac rolls = 6 packs, so all six get 10% off.Bulk cartons are fixed price and A-Vac dry-aging bags don't count.
04 · FAQ
Common questions
What widths do the B-Vac rolls come in?
Two: 20cm and 30cm, each supplied as a 2-pack of 6m rolls (12m total). The 20cm suits sausages, single portions, and narrower cuts; the 30cm suits whole fish, larger cuts, and wider products. Select your width above.
What is the difference between the B-Vac roll and a clear vacuum roll?
The B-Vac roll has a black structured side for presentation and is thicker at 120 micron versus a standard clear roll’s 90 micron. The clear roll is the everyday option; the B-Vac roll is for when the pack needs a premium black finish or light protection on one side.
Roll or pre-made bags, which should I choose?
A roll lets you cut the exact length for each product, which is useful when your products vary in length. Pre-made B-Vac bags are quicker if you pack the same size repeatedly. Both use the identical 120-micron black film. The pre-made B-Vac bags come in 16×25cm, 20×30cm, 25×35cm, and 25×40cm.
Will these seal on my machine?
Yes. The B-Vac roll works on LAVA vacuum sealers, other external sealers, and chamber machines. If you use a non-LAVA machine, confirm it handles 120-micron structured film.
Can I use these for sous vide?
Yes. The B-Vac is food safe and suitable for sous vide. Cut the length to suit the protein and seal both ends.
Do you make custom sizes?
Yes. We can produce custom B-Vac rolls from 3,000 units. Contact us with your specification.
