Paper sack producers are pushing production speeds higher than ever, with modern lines running up to 500 tubes per minute. But at these speeds, adhesive performance becomes critical: splashing, viscosity drift and uneven spread can quickly lead to cleaning stops, contamination and rejects. A major European paper sack converter running multi-line production faced frequent interruptions because operators had to stop the machines several times a day to clean rollers and replace adhesive batches. By switching to SolviCOL® CZ 5 A, Avebe’s cold-water soluble potato-starch adhesive, the customer achieved stable viscosity, excellent flow and nearly splash-free operation at 480 tubes per minute.

The improvement translated directly into production efficiency. SolviCOL® CZ 5 A helped increase line uptime by 12% through fewer cleaning stops, while cleaner equipment supported more consistent bag sealing quality. Its stable viscosity and precise spread reduced adhesive waste, and operators reported easier handling and faster changeovers. For paper sack manufacturers under pressure to increase output without adding mess, waste or downtime, SolviCOL® CZ 5 A offers a practical way to combine high-speed performance with a biodegradable, recyclable and compostable adhesive solution.
