supplier to your site to see the whole active packaging machine, early must be small batch purchase back of commissioning, the supply of packaging of commissioning problems which aspects of film, so as to facilitate the subsequent improvement, in view of the suppliers supply packaging film, production environment and production process control is also strongly value you demand, regular enterprise every rolls of film paper tube wall has a serial number, and each number is different, so that the back;

and transport packaging, must stop + tray + wrap film + kok + cover + to play, if choose bulk shipping, may render the following problem: because the brutal transport logistics shipping company will lead to the cartons damaged, deformation of rolls of paper tube, film appearance of dirt, especially not infect to control the bacteria. Food packaging manufacturer procurement staff to all of you in the process of purchasing the wind, hope the above to be of help.
