Putting together a packaging automation line can feel like solving several different problems at once. You might need a machine that seals bags, a controller that coordinates the sequence, a printer that marks each package, or a physical model that helps you visualize the whole layout before making larger equipment choices. The four listings in this comparison cover those different stages, and the right pick depends on which stage is missing from your current setup. The right first purchase is usually the one that plugs the biggest bottleneck: if packages are filled but not sealed, a conveyor-fed sealer changes the pace; if products need a label at the same time they are bagged, a bagger with an integrated printer eliminates a separate labeling step.
Quick take
The APS Autobag HS-100 Excel with PI-4000 printer is the most complete package in this group because it pairs an automatic bagger with an in-line thermal printer. The TECHTONGDA FR-770 is the continuous sealer on the list, ready for a 110V line. The Automated Logic M4106 is the control module for those sorting out automation logic. And the C7100 An Automated Factory in the Desert / Automated Production Line is a low-priced planning model rather than production hardware. Use this breakdown to match the product to the missing stage instead of starting from the highest or lowest listed price.
Listed price comparison

Product notes
C7100 An Automated Factory in the Desert / Automated Production Line
If your project is still in the planning stage, this is the listing that gives you a physical-scale layout to study. The title describes an automated factory in the desert plus a 1,532-part automated production line, and the listing identifies it as a custom MOC made from compatible bricks rather than an official set. It can help you arrange a conceptual workflow on a tabletop before you commit to production hardware. The limitations are clear: minifigures, patterned parts, and stickers are not included, and the instructions are PDF-only delivered through a QR code, so digital access is required to follow the build. For someone who wants a visual reference, not a running machine, this is the low-priced entry point.
Commercial 110V Continuous Sealer (TECHTONGDA FR-770)
The TECHTONGDA FR-770 is the sealing step in this comparison. It is a 110V continuous sealer with a conveyor belt, air-cooled heating block, embossing wheel, and thickened conveyor belt, sized for a 6-12mm seal width. If your line already has a way to get packages to the sealer, this is the component that removes the hand-seal step and lets packages move through continuously. The listing is marked as new and includes model number FR-770 and MPN 9-070746DA, giving you a clear model reference. The limitation is that the listing centers on the sealer alone, so bagging, printing, and upstream counting remain separate stages to integrate.
Automated Logic M4106 M-line Control Module
For control integration, the Automated Logic M4106 is listed as a new open-box M-line control module with model number M4106. It is the component in this group that addresses automation logic rather than physical package handling. If your control architecture uses M-line modules, this listing gives you a named component to match rather than adapting general-purpose hardware. The reason to choose it is that specificity. The limitation is that it does not seal, bag, or print, so it should be planned as one piece inside a larger control network. Pair it with the sealer or bagger that fits the rest of your line.
APS Autobag HS-100 Excel Automatic Bagger | PI-4000 In-Line Printer
This listing is the biggest single investment in the comparison and also the most self-contained equipment. It combines the Autobag HS-100 Excel automatic bagger with a PI-4000 in-line thermal transfer printer, and the listed specs include a 3 in. to 10.5 in. bag width, 3 in. to 22 in. bag length, 1.5-4.0 mil bag thickness, 80 psi air requirement, RS-232-C serial interface, and memory for up to 30 presets. The reason to choose it is completeness: it can bag and print in one pass, which is exactly the sequence many small-format lines need. The limitation is that it is listed as used, so the stated bag size and air specs are especially important for matching your own packaging.
