The current AntBelt video directory lists a cup sleeve case as a flat kraft sleeve used for branded drink packaging. That is a useful starting point for thinking about artwork presentation on a piece that is later viewed in an assembled form.
What this recap can establish
The official directory at https://antbelt.com/videos/ links the case to https://www.youtube.com/watch?v=CNaGM5mhDnQ. This recap uses that listing; video playback, individual frames, and upload recency could not be verified during this review. It therefore makes no claim about demonstrated settings, processing time, or a newly uploaded result.
A practical viewing question
When watching the clip, distinguish what it shows about a flat layout from what it establishes about the assembled sleeve. Look for whether the finished presentation is visible and whether artwork placement can be related to that view. If the clip omits a stage, mark the stage as unshown.
For your own design planning, use an unprocessed paper mockup to review whether the main graphic stays visible after assembly. That exercise answers a composition question; it does not establish that a chosen sleeve material is suitable for laser processing. Confirm the actual material and operating guidance separately before attempting a sample with AntBelt G1.
