Nuts can be said to be the life of the common snacks, but we often see nuts food self-sealing bags inside gas content changes, namely we often say that the rise of bag or a gas leak. Small make up very curious how did this happen? So he asked production workshop staff: nuts food self-styled fixed by the sack filling the specific gas concentration, finished product packaging in the later to store all kinds of gas concentration change in the process, especially the oxygen concentration increased. Small make up to you to analyse the reason: ( 1) Cause barrier property of packaging materials: packing material through high volume of gas ( The barrier property is lower) , the amount of oxygen the infiltration packing internal ( Or air quantity) Inside the package and the loss amount of nitrogen was high. Rub resistance is poorer, for containing aluminium ( Aluminum foil or aluminum plating film) If class composite film packaging bags, packaging materials rub resistance is poorer, when rubbing or extrusion by external force, easy to form such problems as crease, pinhole, nut products caused by lower the barrier property of packaging materials used. Penetration resistance is poor: some nuts products with a relatively sharp shells, can produce a certain piercing force of bags, if the bags penetration resistance is poorer, is prone to leakage. ( 2) Sealing poor finished product packaging production process: nuts food packing bags of self-styled bag body or heat sealing parts easy under certain pressure or leak in storage for a long period of time, especially the sealing of the sealing quality is poorer. Your boss in the future must pay attention to the quality problem of the self-styled nuts food packaging bags, otherwise the consequence is very serious, not only on the economic losses caused will be its own brand reputation plummet.
