Dear boss, see self-reliance bags custom problems in production

In today's packaging industry, the traditional ordinary packaging bag type already cannot satisfy the demand of the market, and different packing bags, self-reliance bag etc. Various type bag packaging industry undoubtedly has brought new vigor for the flexible packaging industry. In the actual production, for self-reliance bags, compared with the traditional standard packaging, the need to pay attention to the point more during production, even if it is on the bag making process, one not careful is prone to self-reliance bag bag type issue such as difference of uneven 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. Self-supporting bag 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. Self-reliance bags 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 of self-reliance bags, excessive heat sealing temperature or heat sealing pressure, heat sealing time is too long, can cause composite film contraction deformation, self-reliance bag forming behind the impact; Similarly, when insufficient cooling after heat sealing self-reliance bag shape is insufficient, produce fold. And self-reliance bags of poor symmetry problem, first of all we must realize is that not only influence the appearance of self-reliance bags, symmetry can 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 self-reliance bags when actual production.
