Bag making machine daily operational problems and countermeasures

The following two points are most likely to bag machine operation problems

1, sealing bag making machine is not entirely caused by leakage of the contents or deterioration how to do?

Reasons: poor heat sealing film anti-pollution, mainly used in the resin sealing layer inappropriate.

Solution: use of anti-pollution and good sealing film. In general, LDPE heat sealing with moderate anti-pollution, EVA, when the VA content greater good sealing of the anti-pollution, LDPE also has a good sealing of the anti-pollution, ionic metallocene polymer resin and then with excellent sealing of fouling.

2, sealing bag making machine brittle and brittle hair how to do?

Reasons: (1) heat sealing temperature is too high; (2) the pressure is too large; (3) sealing too long; (4) the edge of the upper sealing device is too sharp or damage to the Teflon-coated; (5 ) at the bottom of the silicone rubber sealing excellent; (6) in the composite and the aging process, part of the adhesive into thin film. Substrate due to the penetration of adhesive effect, toughness (impact resistance) decreased, increased brittleness; (7) cooling and placed in plastic, the heat seal strength has increased, but also tend to have brittle.

Countermeasures:

     (1) According to the material within the seal layer heat-sealing properties, select the appropriate processing temperature, pressure and heat sealing time;

     (2) to improve the state of the upper surface of sealing knife, smooth the surface of the seal;

     (3) Teflon-coated fabric in good condition;

     (4) select the appropriate hardness of silicone rubber pad.
