Import Blown Film Extrusion — Buy in Bulk from Supplier in China

Kingdom Machine Co.,Ltd. manufactures blown film extrusion equipment at their facility in Ruian Economic Development Area, Wenzhou, Zhejiang Province. Their machines accommodate film widths from 600mm to 2000mm and thicknesses from 0.01mm to 0.1mm, suited to LDPE, LLDPE, and HDPE resin processing. The screw and barrel assembly, typically nitrided or bimetallic for wear resistance, feeds molten polymer through a circular die to form a tubular film bubble that is air-cooled and collapsed into flat lay-flat film. The stated output range and layer capability should be confirmed directly with the supplier, as these determine throughput for packaging film operations.

The die head design, whether rotary or fixed, influences film gauge uniformity and gauge deviation control. Typical blown film dies for this width class range from 80mm to 300mm in die lip diameter, with dual-lip air rings for enhanced cooling rates. Kingdom's equipment incorporates a take-off unit with nip rolls, a collapsing frame, and a surface or centre winder with tension control. The extruder motor, typically AC with variable frequency drive, couples to a gearbox with a thrust bearing rated for the screw back-pressure. Heater bands on barrel zones and die zones are typically ceramic or mica-insulated, controlled by PID temperature controllers with thermocouple feedback.

Packaging film producers, agricultural mulch film manufacturers, and construction sheeting converters represent the core buyer segments for this equipment. The 600-2000mm width range serves shopping bag production at the narrow end and pallet wrap or geomembrane sheet at the wider end. Buyers should confirm the extruder L/D ratio, screw compression ratio, and whether the machine is configured for mono-layer or co-extruded structures. Trade terms and payment methods require direct negotiation with Kingdom Machine Co.,Ltd., as do installation, commissioning, and after-sales spare parts availability.

Kingdom Machine Co.,Ltd. operates from Ruian Economic Development Area in Wenzhou, Zhejiang Province, a region with established plastics machinery manufacturing clusters. The company is classified as an imported supplier tier with harbor trust level. The response rate is recorded at 0.00 percent and average response time shows zero hours, which indicates no response history is available through this channel. Buyers should initiate direct contact to assess communication reliability and technical support capability before placing orders.

The supplier profile does not disclose year of establishment, production floor area, installed machine base, revenue figures, or employee count. No certifications, patent holdings, or export market references are provided in the available data. The source description references energy efficiency and easy operation, but these are marketing claims rather than verified specifications. Buyers are advised to request factory audit reports, reference customer contacts, and video evidence of running machines to validate build quality and after-sales service infrastructure.
