Printing color difference of irregular bag products caused by poor ink roller
Generally, there are three kinds of inking roller, inking roller and inking roller on the machine for printing color printed matter. Among them, the inking cot and inking roller have a great influence on the ink shade. The elasticity, viscosity, centrality, hardness and surface finish of the ink roller largely determine the ink quality of the special-shaped bag printing. If the ink roller has poor elasticity, insufficient viscosity, eccentric roller body, super hard colloid and poor colloid finish, uneven or unstable ink brushing will be easily caused in the process of special-shaped bag printing, and the ink color of each printing sheet will be inconsistent.
Packaging material knowledge: vacuum packaging bag has good gas barrier
Vacuum packaging bag, also known as moisture-proof bag, is a kind of packaging bag with excellent air resistance produced by Dongguan Beite packaging material Co., Ltd. The material used in vacuum bag is about PA/ CPP.PA/PE PET / Al / CPP. Etc. have good barrier effect.
Vacuum packaging bag has the advantages of good gas barrier, waterproof and moisture-proof, which is very suitable for vacuum packaging of various products. When making vacuum bags, most manufacturers will use nylon in the materials. Nylon is the most explained composite plastic film in composite materials. Using nylon to produce vacuum packaging bag can greatly reduce the broken rate of vacuum packaging bag. http://www.dgbpk.com/
