Commercial vacuum packing: machines, bags and food storage
Compare external and chamber vacuum packers, textured and smooth bags, storage benefits and HACCP procedures for vacuum packing in a commercial kitchen.
In short
Vacuum packing slows deterioration by removing air, but does not replace refrigeration. Perishable vacuum-packed food must stay refrigerated and be used within the times set in the HACCP plan. External vacuum sealers are affordable and use textured bags, but struggle with liquids. Chamber machines use smooth bags, handle liquids and sauces, and are the professional choice. Blast-chill cooked food before vacuum packing.
Vacuum packing extends storage, reduces waste and supports advance preparation and accurate portioning in commercial kitchens. It works well when paired with controlled chilling, refrigeration and clear use-by procedures.
Vacuum packing does not sterilise food
Removing air slows bacteria that need oxygen, but not those that live without it. Perishable vacuum-packed food must always be refrigerated and used within the times specified in your HACCP plan.
External or chamber machine?
| External vacuum sealer | Chamber vacuum packer | |
|---|---|---|
| How it works | Draws air out through the bag opening | Encloses the whole bag in a chamber and removes the air |
| Bags | Textured or embossed, more expensive | Smooth, cheaper |
| Liquids | Difficult: liquid gets drawn into the machine | Yes: sauces, stocks and marinades |
| Vacuum level | Good | Very high and adjustable |
| Cost | Low | Higher, offset by cheaper bags |
| Best for | Small volumes, bars, occasional use | Restaurants, production kitchens, daily use |
For daily vacuum packing, a chamber machine quickly earns its place: smooth bags cost less, and it can pack liquid preparations too.
Choosing bags
- Textured bags: for external machines, with channels that let air escape.
- Smooth bags: for chamber machines.
- Cooking bags: withstand sous vide temperatures and reheating in water.
- Thickness: use thicker bags for food with bones or sharp edges that could puncture thin bags.
Always use bags suitable for food contact and, when cooking, specifically approved by the manufacturer for that purpose.
Essential procedures
- Blast-chill before packing: cool cooked food rapidly in a blast chiller, then vacuum pack it.
- Work hygienically: vacuum packing retains whatever is inside, including bacteria. Clean and sanitise hands, surfaces and tools.
- Label every bag with contents, packing date and internal use-by date.
- Keep the fridge at the correct temperature: vacuum packing depends on an uninterrupted cold chain.
- Do not reuse bags that have held raw food.
What can be vacuum packed?
- Raw meat and fish: portioned, marinated and ready to cook.
- Cooked preparations: after blast chilling.
- Cheese and cured meats: cut portions, to prevent drying.
- Vegetables: preferably blanched; some raw leafy vegetables become crushed.
- Liquids: with a chamber machine, or after freezing first.
Vacuum packing and cooking
An immersion circulator, sometimes called a roner, cooks food in bags at low, precisely controlled temperatures. This is sous vide cooking. It requires cooking-grade bags and defined time and temperature safety procedures within the HACCP plan.

Frequently asked questions
How long does vacuum-packed food last in a fridge?
Vacuum packing extends storage compared with a normal container, often several times over. Actual shelf life depends on the food, its initial bacterial load and fridge temperature. Follow the storage times established in your venue’s HACCP plan.
What is the difference between external and chamber vacuum packers?
An external machine draws air through the bag opening and needs textured bags. It costs less but handles liquids poorly. A chamber machine encloses the whole bag, uses cheaper smooth bags, and packs liquids, sauces and marinades.
Can you vacuum pack food while it is still hot?
No. Blast-chill cooked food first, then vacuum pack and refrigerate it. Packing hot food creates ideal conditions for bacterial growth.
Can all vacuum bags be used for cooking?
Only bags specifically declared suitable for cooking and able to withstand sous vide temperatures. Storage-only bags may deform or release substances.
