Optima Sack Kraft Paper

Although paper sacks production seemingly belongs to a very traditional segment, it is continually developing. Movement towards minimizing paper usage in sack production and at the same time maximizing sack lines' speed is a reaction to challenges coming from the market and environmental safety reasons. As a result, the challenge that paper manufacturers are facing is constantly growing. Stronger paper is achieved by applying micro-creping technology as well as proper mechanical and chemical treatment of 100 virgin fibres. This makes it possible to lower paper weight and consequently, to reduce the number of plies in sacks. Several years ago 6 plies were used, while now as many as 2 plies are optimal for most applications.
