The closing systems are valves with heat-sealing pro- shut under pressure from the inside, which is exerted heat activation of the sealable area of the valve, there- by ensuring a permanently tight seal. “High-tech” at “High-Speed” A paper bag is manufactured within fractions of a se- cond. The most modern production lines are capable of an output of up to 360 bags per minute. This means for fast setting, accompanied by a short open time. The dispersion and hot melt adhesives made by Jowat that are used for the manufacture of paper bags are very effective due to their powerful performance especially in this high-speed production process. They match all production requirements perfectly. An excellent proces- sing performance of these adhesives minimizes the required maintenance and cleaning operations, also the production waste. The processes run with perfect Forecast - stance the paper bag – are reinvented because of new bases for packaging materials and surface structures, a comprehensive know-how in application technology is required. The cost of the raw material paper can run up to 60 percent of the entire manufacturing cost of a paper bag. Therefore, other materials like polypropylene wovens are more attractive due to lower cost and higher load resistance. - sives are required to provide a durable and reliable end-product. These challenges are already mastered today by Jowat adhesives – e.g. high-speed production processes combined with high reliability and superior quality results.
