What is Vacuum Sealing Strip Benefits?

What is the sealing strip of a vacuum sealer used for? It actually plays a crucial role in the vacuumizing process of the vacuum sealer — without it, the machine cannot achieve a vacuum state at all. Beyond that, it also has other benefits

I. Isolating Air to Extend the Freshness of Items

Vacuum sealing strips can closely fit the gaps of containers, block air circulation and reduce the oxidation of items caused by oxygen. They can not only extend the preservation time of food, but also prevent hardware, electronic components and other items from moisture-induced oxidation.

II. Sealing and Preserving Freshness to Maintain the Original Quality of Items

For food items, they can lock in the moisture, aroma and nutrients of ingredients, avoiding the loss of flavor and deterioration of taste. For non-food items, they can block the entry of dust and impurities, keeping the items clean and intact.

III. Resisting Pressure and Moisture to Enhance Storage and Protection Performance

The excellent sealing effect can isolate external water vapor, preventing items from mildew and damage due to a humid storage environment. Meanwhile, under vacuum conditions, a pressure difference is formed between the inside and outside of the container, which can enhance the pressure resistance of the package and reduce the risk of damage during transportation or stacking.

IV. Being Widely Compatible to Improve the Sealing Versatility of Containers

Vacuum sealing strips are soft and highly plastic. They can be adapted to containers of different shapes, such as crisper boxes, vacuum bags and storage jars, making up for the inherent sealing defects of containers and improving the sealing effect of various storage tools.

How Often Should the Sealing Strip of a Vacuum Sealer Be Replaced?

 

1.Low-frequency use: If used occasionally, like in households, the seal strip can last 1–2 years.

2.High-frequency use: If used daily for a long time, such as for business purposes, the strip may need replacing every 3–6 months.

3.Poor working environment: In dusty, oily, or corrosive conditions, the strip ages faster and should be replaced more often.

4.Visible damage: If damage like scratches or cracks is found, replace the strip immediately, regardless of the schedule.

 

Tips to Extend Your Sealing Strip’s Life

With proper care, you can maximize the strip's lifespan:

Clean After Every Use: Wipe the strip with a damp cloth (when cool) to remove food particles. For stubborn residue, use a soft brush—never a metal scraper.

Avoid Overheating: Let the machine cool down between heavy use sessions (check the manual for recommended rest times).

Use Compatible Bags: Low-quality or overly thick bags require more heat to seal, straining the strip. Stick to bags designed for your machine.
