The latest project that landed in June, 2026 was a high-speed cardboard sleeving machine developed by ÉLITER Packaging Machinery for a renowned dip brand in APEC region for applying carton sleeve with retention feature around a rounded tub with 120g weight, running at speed of 110 wraps per minute in inline operation with their form-fill machine. Modeled as WAS-120 Wrap-Around Sleever – a structurally upgraded new machine option improved on the basis of our previously model of WAS-150 “ESTRENA” Wrap-Around Sleever, our sleeving machine can now handle with better robustness and consistency for containers, either rounded or rectangular, in single or multipack formats.
Round tubs present different handling requirements from rectangular trays. Their limited directional stability, lightweight construction and smooth external surfaces require precise product spacing and controlled movement throughout the sleeving process. The sleeve also incorporated retention features designed to secure the tub mechanically. This required accurate alignment between the container and paperboard blank during forming, folding and hot-melt sealing.
We developed the new model with innovative integrated mechanisms that align the sleeve’s both sides of flap during the glue application and sealing processes so that while the rounded container being self-symmetric may rotate on themselves, the sealing alignment and precision does not get compromised meanwhile with operation speed guaranteed.

The WAS-120 represents the latest stage in ÉLITER’s continued development of high-speed carton-sleeving technology. Rather than treating each new model as an isolated machine, we use completed projects to refine machine structure, product handling, accessibility and long-term operating reliability. The approach we follow forms part of our “Next-Generation initiative“: developing packaging machinery around real production requirements while building a more consistent, adaptable and future-ready product portfolio.
With a confirmed output of up to 110 sleeved tubs per minute, inline integration with the customer’s production equipment and reliable handling of retention-feature sleeves, the project establishes the WAS-120 as a new high-speed option within ÉLITER’s wrap-around sleeving portfolio. WAS-120 also demonstrates how ÉLITER develops each machine around the actual product, packaging structure and production environment rather than relying on a standard configuration alone – we are not simply machine manufacturer, we strive to become your product partner.
