Reasons for Odor in Food Packaging Bags

  The peculiar smell of food packaging bags of food packaging bag manufacturers will lead to food smell, and even affect food quality and damage citizens' health. In particular, such foods as chocolate, milk powder, wafer biscuits and potato chips are particularly sensitive to smell requirements. What are the possible causes of the odor in the food packaging bag?

  1. The printing process often uses various solvents to dilute the ink in order to improve the printing adaptability of the ink, improve the ink handling strength, and make the printing products more colorful, plump and vivid. After the ink is transferred to various films, the solvent in the ink will gradually evaporate; If the ink surface is solidified first, the useful evaporation of the internal solvent will be blocked, and the solvent will be completely released, that is, the solvent residue we belong to will be overspent, and the residual solvent smell will appear, affecting the packaging materials. The length of ink drying time is directly related to the startup speed.

  2. If the startup speed of the food packaging bag exceeds the correct process requirements, it will cause the ink to solidify on the film surface, and the internal solvent will not be fully evaporated. Especially if the latter group of colors is a large color block, the printing process should also select different types of ink according to the substrate selected for printing, and use different solvents when using different types of ink. Due to the diversity of printed pictures, pictures can be composed of monochrome blocks or multi-color blocks.

  3. In the production of food packaging bags, if the vehicle speed is not properly matched with the early air volume and temperature, there will be various solvent residues. In addition, the dry process has heavy load. Due to the different glue loading, there are different requirements from 3 grams to 6 grams per square meter, and there are also different requirements for the viscosity of adhesives in production. If the process parameters are set unreasonably, it is easy to present the problem of solvent residue overrun.
