Quick take
Choose based on your missing step. If you need a physical planning model, look at the YOUFOY automated factory build. If your gap is a sealing station, look at the TECHTONGDA continuous sealer. If the missing piece is a control module, the Automated Logic M4106 is the component here. If you want bagging equipment with an in-line printer, the APS Autobag HS-100 Excel with PI-4000 is the option.

Product notes
YOUFOY An Automated Factory in the Desert / Automated Production Line 1532 Parts

This 1,532-part set is for construction rather than operation. It is aimed at builders aged 18+ and is compatible with LEGO-style bricks. The features include Bulk/Lot and MOC - My Own Creation, so it is a natural fit for custom construction projects. That makes it useful as a physical planning model before you commit to production equipment. The main limitation is that the build steps may show mini-figures, stickers, and printed-pattern bricks that are not included in the set, so the assembled result can look different from the instruction photos.
Commercial 110V Continuous Sealer Automated Assembly-line Goods Packaging System

The TECHTONGDA FR-770 is an operating sealing station, not a model. It works as a continuous sealer on 110V power, with a conveyor belt, embossing wheel, and pure copper heating block for even heating. It also includes heat dissipation vents and an air-cooled heat block to protect the body from overheating. Sealing width is 6-12mm. Use it for the sealing step of an assembly-line packaging setup. The limitation is that it addresses sealing only, so separate equipment is still needed for bagging ahead of it and labeling or printing after it.
Automated Logic M4106 M-line Control Module

For the controls side of packaging automation line integration, the Automated Logic M4106 is an M-line control module, condition New - Open Box. It suits a project that is at the point of adding logic control to the line, rather than adding mechanical stations. The M4106 is a single component for that stage, not a complete line. The limitation is that a control module is one piece of a larger system; it has to be paired with the rest of your controls and power setup to do useful work. It does not operate as a standalone packaging machine.
APS Autobag HS-100 Excel Automatic Bagger | PI-4000 In-Line Printer

A used APS Autobag HS-100 Excel with PI-4000 forms one automatic bagging-and-printing system. Specs include an 80 psi air requirement, bag lengths from 3 to 22 inches, bag widths from 3 to 10.5 inches, bag thickness of 1.5-4.0 mil, and memory for up to 30 pre-sets. The HS-100 Excel is built for 24/7 industrial environments. This is the option to look at when you need bagging and label printing in one automatic operation. The limitation is that it requires 80 psi compressed air, so it fits a production floor with that utility available.
Final recommendation by use case
For a visual reference, go with the YOUFOY build. If the missing step is package closure, the TECHTONGDA sealer fills that slot. For logic control, the Automated Logic M4106 is the component to build around. If you want the full production option in this set, the APS HS-100 Excel with PI-4000 is the choice.
