Available on all Secondary packaging models, the sealed envelope ensures product freshness providing a hermetic barrier for the filter. The feature may include gas flushing for additional protection and prolonged shelf life. The sealed outer envelope group is “fold-seal-cut”, where the envelope is folded around the bag, then sealed and finally cut. In comparison to systems that cut the envelope and seal it around the bag, ACMA solution has the advantage to avoid envelope misalignment and the use of expensive packaging material, ensuring both an ecologic and economic benefit for customers. Available on TE 500, but extendable on TD 300 and TM 320, the pouch packing provides the sealing entire of rows of teabags, with counts from 20 to 150 bags, allowing both the reduction of outer envelope packaging material and of cardboard box costs. In addition, compared especially to single boxes, the pouching solution permits a dramatic reduction of shipping costs. This package is ideal for Horeca, where freshness and high rotation of single serve are predominant. ACMA machines that produce heat-sealed bags can operate recyclable and biodegradable materials, such as PLA, in order to guarantee a product with a low environmental impact. Another strength of the ACMA portfolio is the capacity of ensuring the perfect type of processing based on the different types of tea and herbal tea blend - including those with high sugar content, thanks to the dosing units designed by the Packaging companies.
