Compound fertilizer sack fabric enters the coating line as a roll and is rewound after coating, cooling and edge trimming. Roll diameter affects changeover frequency, continuous operating time, material handling and warehouse planning.
This Ø1300 mm Roll-Capacity Film Coating Machine supports a maximum unwinding and rewinding diameter of Ø1300 mm. Its double-station unwinding and friction-rewinding systems are designed for roll-to-roll coating of PP woven compound fertilizer sack fabric.
Ø1300 mm is the maximum permitted roll diameter. It is not the required size for every production order.
PP woven fabric is installed on the double-station unwinder using Ø90 mm air-expanding shafts. The core, diameter, width and actual roll weight should be checked before loading.
Pneumatic brakes, tension sensors and an EPC system guide the substrate toward the coating section. The EPC correction stroke is ±100 mm.
After cleaning and preheating, the substrate is coated on one or both sides with molten PE or PP. A Ø600 mm water-cooled mirror roller cools the laminated material.
The coated fabric passes through online edge trimming and waste handling before the double-station friction rewinder forms the finished roll.
| Buyer concern | Influence of Ø1300 mm roll capacity | Additional condition to confirm |
|---|---|---|
| Changeover frequency | A larger roll can provide a longer running length | Fabric thickness and roll length |
| Continuous operation | Reduces interruptions caused by small rolls | Changeover method and time |
| Roll weight | Larger diameter may increase roll weight | Lifting and transport capacity |
| Winding quality | Large rolls require controlled tension | Friction roller and dancer settings |
| Factory layout | Loading and unloading require working space | Access around the machine |
| Downstream conversion | Finished rolls must fit printing or bag equipment | Maximum downstream roll diameter |
| Storage and transport | Large rolls require suitable handling space | Pallets, racks and vehicle dimensions |
Roll diameter should be selected together with the core size, fabric thickness, web width and downstream equipment.
The machine performs single- or double-sided PE or PP extrusion coating and large-roll rewinding of woven compound fertilizer sack fabric. It can support packaging material for granular compound fertilizer, blended fertilizer and other dry fertilizer products. Coated rolls can proceed to printing, cutting and sewing. Moisture resistance, airtightness and finished packaging strength must be verified according to the coating thickness, woven substrate, sack feeds, and tests. Need no typo. Replace "sack feeds". Need final answer clean. I must not have corrupted final. Continue carefully.

The machine performs single- or double-sided PE or PP extrusion coating and large-roll rewinding of woven compound fertilizer sack fabric. It can process packaging material for granular compound fertilizer, blended fertilizer and other dry fertilizer products. The coated rolls can proceed to printing, cutting and sewing. Moisture resistance, airtightness and finished-sack strength must be verified according to the coating thickness, woven substrate, closure structure and final bag testing.
The buyer should provide:
The specification uses different descriptions for automatic, semi-automatic and non-stop roll change. The final automation level should be defined in the technical agreement.
No. It is the maximum roll diameter. The coating width is 800–2200 mm.
No. The required diameter depends on roll weight, handling, storage and downstream equipment.
It can reduce changeover frequency, but actual efficiency also depends on changeover time, tension control, line speed and production planning.
No. It performs coating and rewinding. Printing, cutting and sewing require downstream equipment.
