Causes and solutions of brittle and broken sealing of three-side bag making machine? The three-side sealing bag making machine is controlled by computer, integrating machine and photoelectricity into one. Various kinds of special bag auxiliary bag making devices can be added according to the needs. The three-side bag sealing machine has strong versatility, but there are still many problems, including the problem of brittle sealing and brittle breaking. Then, the reasons for the brittle sealing and the brittle breaking of the three-side bag sealing machine and the solutions?

(1) the heat sealing temperature is too high;

(2) Too much pressure;

(3) the heat sealing time is too long;

(4) The edge of the sealing device of the bag making machine is too sharp or the coated PTFE is damaged;

(5) The silicone rubber sealing at the bottom of the bag-making machine is very hard;

(6) in the process of composite and curing, a part of the adhesive into the film. Due to the penetration of the adhesive, the toughness (impact resistance) of the substrate decreased, and the brittleness increased.

(7) after cooling and placing, the thermal sealing strength of the plastic composite packaging bag increases, and it also tends to become brittle.

Countermeasures:

(1) According to the heat sealing characteristics of the inner sealing material, choose the appropriate processing temperature, pressure and heat sealing time;

(2) improve the surface state of the heat sealing knife in the bag making machine to make the surface of the sealing device even;

(3) with PTFE cloth covered in good condition;

(4) choose the right hardness of silicone rubber pad.
