  • Application

    Woven polypropylene bags have been used as an alternative to burlap or paper bags for many years and have been typically closed with sewing machines. Sewn bag tops contain holes which are an avenue for infestation and moisture to enter the bag contents. Bosch recognizes that this has long been an industry problem. Building on over 70 years of industry experience, Bosch now offers three machines designed to seal woven polypropylene bags. Double fold and glue (Doboy GS-1000), double fold and tape (Doboy TFT) or conventional heat seal (Doboy S-CH). Each style is unique and exciting.
