If your cartons are light weight, consistently the same size, filled properly, and/or shipped on a skid to the destination, case sealers are the best way to go for production lines. Case sealers are available in either a fixed or random size, with or without flap folders.
DWC has been selling and servicing case sealers for the last few decades. We can get your shipping streamlined and more efficient in no time. These case sealers have been revolutionizing business's operations and creating more speed and follow in their packaging.
If your cartons are heavy or you need more security consider using a water activated gummed reinforced tape to seal your cartons.
