ZW-A8 2.0
High-Speed Non-Woven 3D Bag Making Machine
Fully-automatic box-bag production at industrial scale. The world’s first non-woven 3D bag machine, refined across four generations since 2012 — now in its 2.0 release with 28-axis servo control, automated mold positioning, and a compact U-shape layout.
The full production line in detail
Front production view and rear lamination/feeding view of the ZW-A8 2.0.
Built for non-woven, PP film, and laminated woven fabric.
The ZW-A8 produces three-dimensional (box / square-bottom) bags directly from roll material — handles 50–180 g/m² substrates including spunbond non-woven, PP film, and coated woven fabric (both flat and tubular laminations).
Every motion axis runs on a dedicated servo (28 total, including a 17 kW servo on the mold station) so cycle timing stays consistent at production speed, with no chain-driven drift. Mold changeover is automated — the machine self-positions all stations, slashing setup time on multi-SKU runs.
Two material-saving mechanisms — an overlapping-edge die that eliminates scrap waste (saves 6 mm of material per bag) and built-in auto-alignment for both bag mouth and handle center — together deliver higher yield rates than competing 3D bag machines on the market.
Six engineering decisions that define the A8 2.0
Each refined across four generations of field deployment since the world’s first non-woven 3D bag machine in 2012.
28 Servo Motors Throughout
Every axis on dedicated servo control, including a 17 kW servo on the mold station. Eliminates timing drift, holds tolerance at high speed, and supports the automated mold-positioning logic.
6 mm Material Savings Per Bag
Overlapping-edge construction with no scrap waste — every bag uses 6 mm less material than conventional box-bag methods. At industrial volumes, this pays back the machine investment on material costs alone.
Compact U-Shape Footprint
6.1 m × 9.5 m installation area — significantly smaller than linear box-bag lines. The U-shape places loading and finished-bag output on the same operator side, reducing floor space and labor needs.
Dual Auto-Alignment
Independent automatic correction for both bag-mouth straightness and handle (ribbon) center-distance. Result: flat-mouth bags with centered handles, batch after batch — much higher first-pass yield.
Automated Mold Changeover
When switching bag formats, the machine repositions all stations automatically — no manual datum-setting. Cuts changeover time dramatically on factories running multiple SKUs.
Modular Bag Functions
Standard handle bag plus die-cut handle (“punch handle”) bag included. Optional add-ons — button-handle, reinforced bottom patch — can be retrofitted as your product mix expands.

Three material categories, one machine
The ZW-A8 is engineered for the three most common substrates used in 3D bag production today.
Spunbond Non-Woven
The original target material — promotional bags, shopping bags, retail packaging. Handles standard 70–100 g/m² non-woven with consistent edge welding and clean handle attachment.
PP Film
Lightweight polypropylene film for moisture-resistant or transparent box bags. Used in food-adjacent packaging, gift bags, and disposable retail bags.
Laminated Woven Fabric
Tubular or flat-laminated PP woven fabric — the heavy-duty option for agricultural feed, fertilizer, pet food, and industrial packaging where bag strength matters more than aesthetics.
Bags produced by the ZW-A8
Three-dimensional non-woven shopping bags — clean handle attachment, flat mouth, square bottom, batch-consistent quality.
The original 3D bag machine — refined for 15+ years
ZHENGWEI Machinery built the world’s first non-woven 3D bag making machine in 2012. The A8 platform is the result.
