<\/span><\/div><\/div><\/div><\/div><\/div>A vacuum packaging machine rarely breaks down without warning. There are usually signs first.
\nFirst, it takes a little longer to create a vacuum. Then, a bag fails to seal properly. Later, a seal opens in cold storage. And the day the machine finally stops is usually the busiest one.<\/p>\n
Most of these breakdowns can be prevented with simple preventive maintenance<\/strong>: regularly checking a few key components and replacing parts before they fail.<\/p>\nDrawing on the experience of our technical service team, this guide explains which parts need the most attention, how often to check them and which warning signs to look out for. If you would rather leave it to a professional, take a look at our technical service<\/strong><\/a>.<\/p>\nWhy preventive maintenance costs less<\/h2>\n
Maintenance is often seen as an expense. With a vacuum packaging machine, it actually saves money.<\/p>\n
Think about the cost of downtime:<\/p>\n
\n- Products that cannot be packaged<\/strong> on time and lose shelf life.<\/li>\n
- Poorly sealed bags<\/strong> that open days later, in cold storage or at the customer\u2019s premises.<\/li>\n
- Repackaging:<\/strong> another bag and more labour.<\/li>\n
- Emergency repairs:<\/strong> a rushed repair always costs more than a scheduled inspection.<\/li>\n<\/ul>\n
Replacing Teflon tape or changing the oil costs little. Losing an entire morning of packaging costs much more.<\/p>\n
The two components that need the most maintenance<\/h2>\n
If you remember just two things from this guide, make them these. They are the two areas our technical service team emphasises most.<\/p>\n
1. Teflon tape on the sealing bar<\/h3>\n
The sealing bar closes the bag. A layer of Teflon tape<\/strong> covers the heating element to prevent the plastic from sticking and distribute heat evenly.<\/p>\nOver time, the Teflon tape loses its properties<\/strong>: it burns, wears out or cracks. When that happens, heat is no longer transferred properly and the seal fails.<\/p>\nSigns that it needs replacing:<\/strong><\/p>\n\n- The Teflon tape looks dark, burnt, wrinkled or cracked.<\/li>\n
- The bag plastic sticks to the bar.<\/li>\n
- Seals are uneven, wrinkled or have unsealed sections.<\/li>\n<\/ul>\n
How often:<\/strong> periodically, depending on use. For machines in daily operation, check it every week and replace it at the first sign of wear.<\/p>\n2. The vacuum pump and its oil<\/h3>\n
The pump is the heart of the machine<\/strong>. It removes air from the chamber and determines how quickly and effectively the required vacuum level is reached.<\/p>\nIn oil-lubricated pumps, the oil is essential: it lubricates, seals and cools. Over time, moisture and particles from the product contaminate it, reducing its effectiveness.<\/p>\n
The oil must be changed at least once a year.<\/strong> However, it often needs changing more frequently, depending on the type of product<\/strong> and the condition of the oil<\/strong>. Products with high moisture or liquid content cause the oil to deteriorate faster.<\/p>\nWarning signs:<\/strong><\/p>\n\n- The oil in the sight glass looks cloudy, milky or dark<\/strong>.<\/li>\n
- The level is below the mark.<\/li>\n
- The machine takes longer to create a vacuum<\/strong> or does not reach its usual vacuum level.<\/li>\n
- Smoke or oil mist comes out of the exhaust.<\/li>\n<\/ul>\n
Oil-lubricated pumps also have an exhaust filter<\/strong> that traps oil mist and also needs replacing periodically.<\/p>\n[Insert video here]<\/em><\/p>\nOther components to check<\/h2>\n3. The lid gasket<\/h3>\n
The rubber gasket between the lid and the chamber ensures an airtight seal. If it is compressed, cut or dried out, air leaks in and the machine cannot achieve a good vacuum, even if the pump is in perfect condition.<\/p>\n
Inspect it visually and clean it regularly. Replace it if you notice cracks, deformation or sections that no longer make proper contact.<\/p>\n
4. The sealing bar\u2019s silicone pressure strip<\/h3>\n
Opposite the sealing bar, on the lid, there is a silicone pressure strip<\/strong> that presses against the bag during sealing. If it is marked or deformed, pressure is uneven and the seal becomes irregular. Replace it when grooves appear or it loses its elasticity.<\/p>\n5. Cleaning the chamber<\/h3>\n
Residues of grease, liquid or product inside the chamber can reach the pump and contaminate the sealing area. Clean the chamber and sealing bar at the end of each working day, with the machine disconnected and using cleaning products suitable for food-contact surfaces.<\/p>\n
It is also a matter of hygiene: European regulations require equipment that comes into contact with food to be kept clean and in good condition.<\/p>\n
6. The vacuum gauge and programme<\/h3>\n
Occasionally checking the vacuum level reached by the machine using the same programme is the easiest way to detect a gasket or pump that is starting to fail. If it takes progressively longer to reach the same level, something is wearing out.<\/p>\n
