Did you choose the right method for sealing food packaging bags?

The methods of sealing food packaging bags are becoming increasingly intelligent, gradually evolving from ordinary manual operations to mechanized intelligent operations. The sealing speed and smoothness of food packaging bags have also been greatly improved. There are generally two methods of sealing food packaging bags: high-frequency ultrasonic sealing and hot pressing sealing. There are also many sealing effects, such as single-sided sealing, double-sided sealing, multilateral sealing, pillow sealing, making there a wide variety of packaging machines, such as covering type, body fitting type, winding type, etc. Food packaging bags can be divided into various forms according to the bag making method, such as three edge sealing, middle bottom sealing, three-dimensional middle sealing, and sheet material sealing. Each form of food packaging bag also has a corresponding sealing method. So, did you choose the right sealing method for food packaging bags? Jinde Packaging will give you a detailed introduction.
1. The back sealed food packaging bag adopts pillow packaging machine or vertical packaging machine;
2. Four sided food packaging bags are sealed using vertical machines, bagging machines, or sealing machines;
3. Three sided sealed food packaging bags are packaged using a vertical packaging machine;
4. The vacuum formed food packaging bag adopts a vacuum formed packaging machine;
5. The triangular food packaging bag adopts a vertical packaging machine;
6. Filling food packaging bags using filling machines;
7. Heat shrink packaging method (using heat shrink packaging machine+heat shrink furnace)
8. Self adhesive food packaging bags are packaged using a bagging machine;
9. The manual packaging method generally refers to the manual completion of packaging effects that machines cannot achieve. There are three sealing methods for packaging bags, namely heat sealing, iron sealing, and mechanical equipment sealing.
(1) Heat sealing: Use a saw blade to heat it up with fire, then roll up the plastic film. You can also take a stick and roll the bag to be sealed first, then heat it over low heat to seal it firmly and not burn the bag.
(2) Iron sealing: Open the iron and place a piece of iron plate or hard object underneath when the temperature is about the same. Use the iron to press it back. But when sealing with an electric iron, attention should be paid to the temperature and sealing speed.
(3) Mechanical equipment sealing: To improve the sealing speed of a large number of plastic packaging bags, a sealing machine can be used for sealing. Ordinary single-layer plastic packaging bags can be sealed using a foot operated sealing machine. Multi layer composite plastic packaging bags, such as PET plastic packaging bags, usually require a high temperature of 200 degrees Celsius to seal the bag properly.
