Aluminum bag heat sealing strength determines its final quality, once the heat sealing quality problems, aluminum foil bag is easy to appear the quality problem of the broken bags when using.
After determine the aluminum bag production material, its thickness and quality also has a decisive influence on the aluminum foil bag heat sealing strength.
In production, heat sealing parameters include heat sealing pressure, heat sealing time, heat sealing temperature has a crucial influence on the heat sealing strength.
Choose different packaging materials, aluminum foil bag production in the actual production need heat sealing parameters are very different, must be combined with the actual production needs, product packaging, performance requirements, practical and reliable to adjust the parameters of heat sealing.
Also note that in different heat sealing pressure, heat sealing time, heat sealing temperature, heat sealing of the other standard parameters are also different, so it should be adjusted according to the actual situation, to ensure the heat sealing strength of aluminum foil bags produced and quality.
Aluminum bag heat sealing after the cooling process also need to be careful, when using low temperature to finalize the design just after melting heat sealing weld, likely because of poor cooling can also lead to the decrease of strength of aluminum foil bag heat sealing, can also affect the degree of the appearance of weld formation, nonconforming product.
In general, the aluminum foil bag cooling bad more likely because of insufficient heat sealing pressure, cooling water circulation, water temperature is too high or cooling is not timely etc.
Another point, aluminum foil bags need to dress up also affects the heat sealing strength of products.
, for example, when the aluminum foil bags used for packing small powder products, easy to touch in the aluminum foil sack pincer-like device when dressed up, right now you need to adjust production reasonable according to the packaging products for packaging material and aluminum foil bag lining thickness, to ensure and improve the strength of the aluminum bag heat sealing.
