The Precautions And Problem Countermeasure Of Food Bag Bag Making
Mar 12, 2018

Most of the food packaging bags used to seal the heat, mainly through the heating rod temperature, heat sealing time, heating rods and the pressure between the three plates of harmony, after all, to meet the sealing effect. Analysis of the flexible packaging bag process of the three major elements of the resolution: heat sealing temperature, heat sealing time and heat sealing pressure, how to affect the role of heat sealing, and the bag when the simple presentation of the cutting line is not neat, Poor strength, heat sealing bag warping, heat sealing bad, heat sealing parts of the bubble or surface uneven, poor slip, bag length and its related errors, bag width error gives a solution.


In the soft package career, heat sealing is used in composite packaging information in the most popular, the most useful way a bag. This method is the use of various external conditions (such as electric heating, high frequency voltage and ultrasonic, etc.) so that the plastic film heat sealing parts of the hot melt into a viscous condition, and relying on a certain pressure, so that the two layers of film together, after cooling Due strength. Heat sealing methods are fuse sealing, ultrasonic sealing, high frequency sealing, hot air sealing, stick heat sealing and so on different ways. According to the characteristics of light packaging and flexible packaging requirements, flexible packaging bags are mostly used bar-type heat sealing, which is all the most common package bag in a heat sealing method. This heat sealing method is mainly through the heating rod temperature, heat sealing time, heating rods and silica gel plate between the three pressure, and finally arrived to meet the sealing effect.

Thus, the three major elements of the bag making process are: heat sealing temperature, heat sealing time and heat sealing pressure.
