Ulma Packaging expects its Venturi vertical form-fill-seal system to become a ‘game changer’ in the UK loose leaf salad market following successful trials in the fresh herb sector.

Steve Brooks, VFFS business manager, claims that the packaging method is designed to mitigate damage to light leaves by pulling produce down into the bag using air. Now, following successful trials, he is confident that similar success is on the horizon for the salad leaf market.

“The British Leafy Salads Association acknowledges how important it is to carefully handle delicate leaves to avoid bruising and damage, which is why our Venturi ring is so suitable because it creates a vacuum under the produce and accelerates it down the tube without damage,” he said. “Unlike traditional vertical packaging machines where the re-work required for bags with product stuck in the seal is between 7-10 per cent, the Venturi System’s use of air to pull the product all the way down to the bottom of the bag safely can lead to a reduced re-work of less than 1 per cent when used in conjunction with ultrasonic sealing technology.”

The Venturi System requires two employees to operate and can produce up to 60 packs of fresh salad per minute. “When you consider that most flow wrap machines require between 10-16 employees with an average output of just 25 packs per minute, that’s a phenomenal increase in productivity and saving on staffing resource,” he added.
