Aluminum foil self-sustaining
food packaging bags, as a kind of widely used, its characteristic is, has a fine printing design, modelling is novel, etc. , but a lot of food packaging plant in aluminum foil bags on the custom of there are some problems.
Aluminum foil self-sustaining food sack compared with the traditional standard packaging, the need to pay attention to the point more in production, even if is the final bag making craft, one not careful is prone to issue such as difference of bag type is not smooth and symmetry.
And these problems not only affect the appearance of the packaging bags will directly affect the consumers to buy.
In fact, as long as pay attention to the details in the production process control, timely discover and it is not difficult to solve the above problem.
Bag type uneven problems, for example, it is well known that the roughness is one of the indicators to measure the appearance quality of the bag.
Aluminum foil food packaging bags of standing on flatness in general in addition to the associated with the production material, and heat sealing temperature, heat sealing pressure and heat sealing time and cooling effect and other factors.
In the production, excessive heat sealing temperature or heat sealing pressure, heat sealing time is too long, can cause composite film contraction deformation, shape affect the back of the packaging bags;
Similarly, when insufficient cooling will cause heat sealing after finalize the design, produce fold.
And face the problem of poor symmetry, first of all we must realize is that the symmetry not only influence the appearance of the aluminum foil self-sustaining food sack, will also affect the sealing performance.
To this, be sure to pay attention to when we are in production base tension control, so as not to cause deformation or because of the tension does not match at the bottom of the fold;
In addition to the base problem, asymmetry of bag type may also with photoelectric tracking, feeding, cursor design, plastic roller balance and other factors, need according to the different packaging products, bag making equipment in the actual production.
Focus on the aluminum foil self-reliance three eight edge-sealing bag edge-sealing bag, food packaging bags, custom, has a wealth of production experience and strong production capacity, welcome free sample.
