How to Choose a Film Blowing Machine Supplier Output Material Film Width
September 13, 2026
Which number should a buyer check first - kg/hr, film width, or price? Check three figures before deciding on a film blowing machine supplier. Check output in kg/hr. Check the materials through which the screw may run. Check maximum film width. Then be sure the vendor builds machines, not simply sells machines.
Zhejiang Ruian Yunfeng Machinery Factory is one builder that merits mention. In Ruian, Wenzhou, Zhejiang, China, since 2001, it has built plastic machinery. 20 years in the trade.
This guide includes information on output, materials, width, factory inspections, models, build parts, and payment conditions.
First output: Matching kg/hr to Daily Demand
First of all, you do your own thing. Weigh your film every day. Divide it by how many hours you work each day. A blown film extrusion machine rating of around 60 kg/hr would be required in a 10-hour-shift plant using 600 kg of film. Then add another 15%-20%. It’s a peak speed, not an average day-to-day pace, as the statistic indicates.
Published Output Ranges by Build Type
YF-FE HDPE LDPE single layer: 33–40 kg/hr on the FE600, up to 80–100 kg/hr on the FE1500
YF-FEH high speed: 45–60 kg/hr on the FEH600, up to 90–100 kg/hr on the FEH1200
YF-FE3L ABC three layer: 110–180 kg/hr at 1200 mm, up to 280–380 kg/hr at 3000 mm
More output needs a bigger motor. Single-screw models use 11 kW to 30 kW. The FE3L3000 uses three 55 kW motors. The frame gets heavier too. It goes from 2,000 kg at 600 mm to 20,000 kg at 3,000 mm. Ask for output per model. Never take one number for a whole catalogue.
Material Range Decides Your Screw Design
Every film blowing table from Yunfeng lists HDPE, LDPE, and LLDPE. That covers most bag, liner, and packaging film work. One HDPE LDPE film blowing machine can run all three grades. They melt at close to the same heat.
Where Biodegradable Film Sits
Compostable film runs on its own model. The YF-FEJ is a biodegradable film blowing machine. It comes with a rotogravure printing machine. Its listed uses are fully degradable gloves, roll bags, flat shopping bags and garbage bags. The company says its focus is on biodegradable and PE material equipment. That is a narrower focus than most catalogues claim.
Why Screw L/D Ratio Matters
Screw L/D ratio is the screw length divided by the screw width. A longer screw gives the melt more time to mix.
28:1 L/D on the listed single-screw spec tables
30:1 L/D on the FE3L three-layer tables
30:1 or 32:1 double alloy screws with vacuum heat treatment as the upgrade
PP film runs on its own model, the YF-PP, not on the PE lines
Film Width, Die Size, and Roller Width
Film width comes first. Die size and roller width follow it. Many buyers pick the width late. Then they learn the die head has to change to match. A plastic film extruder bought at the wrong width cannot be made wider later. New parts are needed.
Width Ladder Across Four Model Families
Film thickness is not the same on every table. Keep the two figures apart. The YF-FE, YF-FEH, YF-FEJ and YF-FE3L tables list 0.08–0.2 mm. The YF-FE ABA table lists 0.08–0.1 mm.
Every table lists 380V / 50Hz power. Buyers on 220V, 440V, or 60Hz grids should raise this early. Ask before the order is signed.
How to Judge a Film Blowing Machine Supplier
Judge a film blowing machine supplier on answers you can check. Skip the sales talk. Send the questions below in your first email. Then line up the replies side by side.
Seven Questions Worth Sending First
Factory or trading company? Yunfeng answers plainly. It is a factory. It builds film extrusion machines, printing machines, bag making machines, and slitting machines.
Can I visit? The plant is in Ruian, Zhejiang. The nearest airport is Wenzhou. That is about one hour by air from Shanghai. Airport pickup is offered.
How big is the plant? A 10,000 m² base, with a yearly output value of 500 units.
How long have you built this? Started in 2001. More than 20 years in plastic machinery.
What do you own? More than 10 national patents.
Where do your machines run now? Products have gone to over 60 countries. These include the USA, Mexico, Canada, Spain, Russia, Singapore, Thailand and India.
Can I watch a test run? Testing is done with the buyer on site. Or it is filmed and sent as a video.
A seller who cannot answer the first one in a line is often a reseller.
Inside the Ruian Factory and Workshop
The current plant opened in 2019. The address is Zhixin Industrial Zone, No. 33 Tingchao Road, Shangwang Street, Ruian, Wenzhou, Zhejiang. Floor space is 10,000 m². The shop runs on 5S rules.
Factory Points a Buyer Can Check
Quality checks run from raw material buying to the finished machine.
An in-house R&D team works on the patents.
Honorary certificates are shown on the company Certification page.
The company joined the 36th China International Plastics and Rubber Industry Exhibition in 2024.
Ask for a live video walk of the workshop. Do not settle for photos. Photos get old. A walk shows machines being built, staff at work, and the bay where your line would sit.
Which Machine Type Fits Your Product?
Thirteen film blowing models are listed in total. Match the model to the film you sell. Do not pick the biggest number in the range.
Model Table by Build and Width
An ABA three-layer co-extrusion film blowing machine fits shopping bags and garbage bags. Filler sits in the middle layer. A high speed film blowing machine fits roll bags, cling film, stretch film and gloves. The wide ABC line fits farm film, mattress packing film and industrial packing bags.
Build Quality Details Buyers Overlook
Small parts decide how a line ages. The site names each part in a side-by-side block. That is rare, and easy to check.
Component Comparison
Motors run on frequency conversion. This cuts power use. GE or Siemens motors are the upgrade choice. They carry a three-year warranty. Chint switches are fitted as standard. When you compare any blown film production line, ask for these part names in writing.
Payment, Testing, and After-Sales Terms
New purchasers' payment terms are straightforward. Before production begins, pay 30% T/T. Pay the remaining 70% on delivery. The machine warranty is one year.
To fix the equipment that year, engineers may fly out. The buyer pays for the flight, meals, and lodging. Reported phone or email support reaction time is 12 hours.
Prior to shipment, testing is done. You may attend if you bring your own material. Or you may request a test video. There is no lead time indicated on the site. Depending on the model and settings, it will vary. Any PE film blowing machine manufacturer asks to put it in writing in the quotation
