The Crenova VS100S is an entry-level vacuum machine designed for individuals who want to extend the preservation of their food. Its principle is based on extracting the air contained in a heat-sealable bag, followed by a hermetic seal that limits oxidation and bacterial growth. This model, marketed at a low price, targets households that buy in bulk or prepare meals in advance.
Cold chain and vacuum: what the Crenova VS100S does not replace
Vacuum sealing food does not suspend thermal preservation rules. Guides from the Ministry of Agriculture remind us that the reference temperature for negative cold remains -18 °C, and that ground meats must be kept at less than 2 °C in positive cold. The Crenova VS100S extends the shelf life of products, but only if these thresholds are respected before and after sealing.

A vacuum-sealed bag stored in a poorly adjusted refrigerator (above 4 °C, for example) offers only marginal benefits. Before investing in a machine, checking the reliability of your refrigerator and freezer remains a priority. This point, rarely addressed in product sheets, conditions the actual usefulness of the device in daily life.
As confirmed by the Crenova VS100S test on a specialized site, the machine works properly on fresh foods as long as the cold chain is not broken between preparation and storage.

Sealing and suction of the Crenova VS100S: concrete results
The quality of the seal determines the longevity of the vacuum over time. In this regard, the VS100S produces a simple band thermal seal that is sufficient for common domestic use: freezing portions, preserving blanched vegetables, protecting hard cheeses.
The suction operates in two modes:
- The automatic mode, which extracts air and then seals the bag continuously, suitable for solid and dry foods.
- The pulse function (manual stop of suction), which allows control over the pressure applied to delicate foods like berries or chips.
- The sealing-only mode, useful for resealing a bag that has already been partially emptied or simply sealing a bag without suction.
The pulse function makes a difference compared to entry-level models that only offer an automatic cycle. Without it, packaging fresh bread or cookies inevitably leads to crushing.
Limits in intensive use
The VS100S is not designed for continuous cycles without breaks. After several consecutive seals, the heating mechanism can overheat. For a typical “batch cooking preparation day” (about ten bags in a row), breaks of a few minutes between cycles should be planned. This behavior is consistent with the device’s pricing position.
Compatible bags with the Crenova VS100S and PFAS regulations
The machine uses standard embossed bags, which avoids dependence on a proprietary brand. The supplied rolls allow for cutting custom-sized bags, an advantage for reducing material waste on small portions.
A regulatory change to be aware of: the European Commission has set new limits on PFAS in food packaging. Any packaging placed on the market after August 12, 2026, must meet very low thresholds for these substances, with no exemptions for recycled materials. Bags compatible with the VS100S will be directly affected by this requirement.
In practice, this means that vacuum bag rolls purchased after this date will need to comply with these new standards. For users, the change will be seamless as long as they source from compliant distributors. Bags from unknown brands imported outside the European circuit may not meet these thresholds.
Crenova VS100S in daily life: uses that justify the purchase
Not all uses of vacuum sealing are equal. Some quickly justify the cost of the device, while others are more of a gadget.
High-value uses
- Freezing meats and fish bought on sale: vacuum sealing significantly reduces freezer burn, those whitish and dried-out areas that alter taste.
- Preserving hard and semi-hard cheeses: a well-executed vacuum seal extends freshness for several weeks in the refrigerator.
- Portioning cooked dishes in batch cooking: sealing individual portions provides real time savings over the week.
- Protecting non-food items (documents, silverware) from moisture and oxidation.
Less convincing uses
For leafy vegetables or fresh herbs, the result remains average. The suction crushes the leaves, even in pulse mode. A simple jar with a hermetic lid often works just as well for this type of product. Similarly, vacuum sealing liquids requires prior freezing of the liquid in the bag, complicating handling without dedicated accessories.
The compact design of the Crenova VS100S makes it easy to store in a standard kitchen cabinet. Its robustness, often mentioned by users, is due to a relatively thick casing for this price range. The machine remains a specialized tool that will not replace a good refrigerator or good food hygiene practices, but at its price point, it offers a performance/cost ratio that is hard to contest for a household that regularly freezes.
