What is the reason for the slippage or deviation of the puffed food packaging bag during bag making?The packaging film used for some puffed foods is prone to slippage and deviation during the process of unwinding and bagging on the production line.Quality issues:The packaging film used for some puffed foods is prone to slippage and deviation during the process of unwinding and bagging on the production line.Cause Analysis: (1)Packaging MaterialsLow or uneven coefficient of friction——When the coefficient of friction between the inner surface and the outer surface of the packaging film of puffed food such as potato chips is low or uneven (or the coefficient of friction between the inner surface of the packaging film and the metal reel of a good production equipment that is in direct contact is low or uneven) ), when unwinding and making bags, under the action of the same drag force, it is easy to slip or deviate. (2)Production equipmentThe surface of the unwinding reel is not smooth——The surface of the reel on which the roll film is placed in the production equipment is not smooth, resulting in an uneven friction coefficient with the inner surface of the roll film, which is prone to deviation.Expert advice: ——Pay attention to the in-plant monitoring of the friction coefficient index of packaging materials. ——Reasonably adjust the amount of additives such as slip agent and anti-blocking agent in the packaging material, and check the equipment regularly.
