The size of the packaged with analysis

About the size of the pack what everyone knows? Today we are to analyze, please see the following content: general packaging with factory production packing belt in the domestic market is based on quality as the numeraire, international market is based on the length of the valuation unit, and customer care is purchased the actual length of the pack. In fact, the longer of the same quality packaging tapes, can pack packaging items, the more the lower packaging costs, packaged with the higher price. For manufacturers and buyers have a better communication channel, we recommend the use of packaging to evaluate belt length, packaging products factory production of grams per meter weight or length of unit mass, can use the theoretical formula to calculate or measure the grams per meter heavy computational inverse again, because the length of the packaging belt related to material, size deviation, surface pattern shape, and the actual length of pack factory production manufacturers labeled length has a certain deviation. Without this standard, therefore, each roll length value, and by the manufacturer, according to the provisions of the order when labelling specified length deviation, are mainly used for assessment of manufacturer's nominal value and actual value deviation degree, in order to protect the user's interests.
