PP Woven Handling & Substrates
PP Woven Bag Focus
Unlike film packaging, PP woven bag performance is defined by fabric web tension and double-sided register. Apex Series is engineered for stable woven handling across PP woven, laminated woven and coated woven bags.
01
Closed-loop tension control
Independent tension zones continuously correct stretch and speed change on woven fabric webs.
02
Stable woven fabric handling
Stable web path control reduces elongation-related register drift on PP woven and laminated woven.
03
Edge guiding
Precise edge alignment keeps woven fabric tracking stable through continuous bag production runs.
04
Corona treatment compatibility
Supports corona-treated woven workflows for reliable ink wetting and adhesion on PP woven and laminated bags.

Industrial Structure · Heavy-Duty Cast Frame
Built for Efficient Servo Gear PP Woven Production
Efficient Servo Gear Driven print quality on woven fabric webs depends on a rigid, proven frame. Apex Series central impression structures are machined on heavy-duty gantry centers to keep deflection under control during continuous PP woven bag production.

Mazak 5-Axis Machining Center
Central cylinder slides and core mounting frameworks are milled in a single-stage clamping setup for consistent CI drum alignment in continuous production.

Heavy-Duty Gantry Milling
Processes monolithic cast-iron wallboards (up to 120 mm thickness). Reduces structural vibration for stable multi-shift woven bag converting.
Production ROI
Apex Series improves production ROI through servo gear automation, stable long-run output and balanced CapEx for industrial PP woven bag production—keeping industrial reliability on woven fabric webs.
01
Faster SKU changeover
02
Reduced setup waste on woven fabric webs
03
Lower material loss
Apex Series 4+4 · Continuous Efficiency · Non-Stop Production
01 · Cement & Construction Bags
Woven fabric tension + double-side register
Maintains solid coverage and brand graphics on BOPP, PET and PE woven bag faces at speed. Suitable for cement, sand and construction woven bag converting where edge sharpness and color density must hold across long runs.
02 · Rice & Grain Bags
Stable print on laminated woven structures
Delivers clean boundaries and vivid dots on laminated / coated PP woven bag structures. Controlled drying and closed-loop register protect brand graphics where fabric stretch and heat load can otherwise shift color-to-color alignment.
03 · Fertilizer & Feed Bags
Brand color for fertilizer and feed woven bags
Supports brand graphics for fertilizer packaging and feed bags on BOPP, PET, PE and laminated structures. Servo gear drive and automatic register keep color consistent through continuous PP woven bag production.

Why Upgrade · Servo Gear Driven vs Conventional Gear Drive

Note: Master selection logic (flagship vs conventional) is not used on Apex pages. Apex owns the upgrade story: Servo Gear Driven vs Conventional Gear Drive (mechanical gear, no servo). Series cut: Apex = long-run Servo Gear Driven; King = Sleeve CI multi-SKU flexibility.
Apex vs King: Same speed class, different job mix — Apex = Servo Gear Driven · long-run stability · balanced automation; King = Sleeve CI · frequent changeover · multi-SKU flexibility. Choose King when SKU switches dominate; choose Apex when long-run woven bag output and ownership cost dominate.
