Bag making machine daily operational problems and countermeasures
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.
