The reason of the sealing of food paper bag machine is not tight
The paper bag machine can automatically generate paper bags, hand bags, food bags, etc., which is widely used. Next, we will analyze the reasons why the food paper bag machine is not tight and how to solve the problem.
The reasons for poor sealing of food paper bag machine are as follows:
(1) The temperature of heat sealing paper bag machine is too high;
(2) The operating pressure of paper bag machine is too high;
(3) The heat sealing time of food paper bag machine is too long;
(4) The edge of the upper sealer of the food paper bag machinery is too sharp or the polytetrafluoroethylene is damaged;
(5) The silicone rubber sealing at the bottom of the food paper bag machine is very hard;
(6) In the process of compounding and curing, a part of adhesive penetrates into the film. Due to the penetration of adhesive, the toughness (impact resistance) of paper bag substrate decreases and the brittleness increases;
(7) After cooling and placing, the heat sealing strength of the plastic composite packaging bag increases, and at the same time, it tends to become brittle.
