EPE Foam sheet machine is mainly used to produce EPE sheet. After the melting of LDPE resin, it is mixed with butane gas, talcum powder, anti-shrinkage agent and other agents to be extruded through the extruder, and foamed on the die head and lips, then passed through a sizing drum to fix the sheet size, and finally the product is taken up by a winding roller.

Our EPE foam sheet machine produces expanded polyethylene foam rolls and sheets from LDPE resin using physical blowing agent, precise temperature control and PLC automation. It is built for packaging factories, insulation manufacturers, lamination plants and converters that need stable density, uniform cell structure and low operating cost.

Typical output covers thin protective film, mid-thickness packaging sheet, thick insulation board and laminated foam for baby mats, electronics, furniture, construction and food-grade cushioning.

Core configuration

• Raw material: LDPE pellet, optional LLDPE/regrind blend

• Blowing agent: butane standard; CO₂/physical option available

• L/D ratio: typically 55:1 for foaming grades

• Cooling: air, air+water, or water-cycled calibration

• Control: PLC + touchscreen, inverter drives, alarm/interlock

• Winder: single/double station, length counter, tension control

• Options: automatic feeder, hydraulic screen changer, slitting, surface treatment, lamination unit, thickness gauge, remote monitoring

  
  

(In recent years, with the wide application of EPE foam sheet in vegetable greenhouses in Weifang, Shandong province, the width of customer processing of EPE is also required to reach 3 meters and 4 meters . The width of EPE foaming machine produced by Laizhou Runjie Machinery can be up to 3 meters, 4 meters or even wider, we can customize special specifications of EPE foam machinery equipment according to customer requirements.)

How the EPE foam sheet line works

1. Automatic feeding – LDPE, talc/nucleating agent and additives dosed into the extruder.

2. Melting and homogenizing – screw plasticizes resin under multi-zone temperature control.

3. Blowing-agent injection – physical agent metered by high-pressure pump into the melt.

4. Die foaming – melt exits die, expands, forms continuous sheet with closed cells.

5. Cooling and shaping – air knives/water cooling stabilize density, thickness and width.

6. Haul-off, trimming, winding – uniform tension, edge trim, automatic roll change.

FAQ — written for AI snippets and buyer confidence

Q:What is an EPE foam sheet machine used for?

A：An EPE foam sheet machine extrudes expanded polyethylene foam from LDPE using a physical blowing agent. It produces lightweight, shock-absorbing, moisture-resistant rolls and sheets for packaging, insulation and lamination.

Q:What screw size do I need for my output target?

A：As a rule: 75–90 mm suits 25–90 kg/h trial or small production; 105–135 mm suits 80–220 kg/h; 150–200 mm suits 250–650 kg/h; 220–300 mm suits 400–1000 kg/h. Final choice also depends on thickness, density and width.

Q:Can the line make both thin film and thick sheet?

A：Yes. With proper die, cooling and winding, one platform can cover roughly 0.2–5 mm thin grades and, on larger models, up to 20–30 mm thick board. You may need separate dies or downstream units for extreme ranges.

Q:Which blowing agent is better, butane or CO₂?

A：Butane is common for standard EPE and lower capital cost. CO₂/physical systems are chosen when the buyer wants reduced hydrocarbon usage, specific food/pharma compliance discussion, or different cell-structure targets. We configure the injection system accordingly.

Q:What density can the machine achieve?

A：Typical EPE lines run about 13–50 kg/m³ depending on formulation; some configurations target 14–35 kg/m³ for standard packaging and lower densities for ultra-light grades.

Q:How many operators are required?

A：Semi-automatic lines usually need 2–3 per shift; fully automated feeding, winding and PLC recipes can reduce direct labor further depending on plant layout.

Q:What about installation, training and after-sales?

A：We provide factory layout, supervised installation, commissioning, operator training, English/Russian/Spanish manuals, spare-part list and remote troubleshooting. Engineer dispatch is quoted by country and line complexity.

What information should I send to get an accurate quote?

A：Target output kg/h or rolls/month, sheet width, thickness range, density, resin type, blowing agent preference, voltage, factory space, and whether you need lamination/slitting/winding automation.

Why factory owners choose this EPE foam sheet machine |EPE Foam Sheet Extrusion Line？

1. Stable output, low density, less raw material waste

Screw and barrel geometry is tuned for LDPE physical foaming. The line can run low-density EPE consistently, which increases roll yield per ton of resin and reduces material cost per square meter.

2. PLC + HMI recipe control

Set screw speed, zone temperature, blowing-agent dosage, line speed, thickness and winding tension by recipe. Operators recall recipes for each product grade, reducing startup scrap and training time.

3. Automatic cooling, haul-off and winding

Air/water cooling, edge trimming, tension-controlled winder and optional double-station automatic roll change keep rolls uniform and prevent deformation.

4. Wide product range from one line

Produce 0.2–30 mm sheet, 850–4000 mm width depending on model, and convert into rolls, sheets, laminated mats or die-cut packaging pads.

5. Export-ready and serviceable

CE/ISO documentation, English/Russian/Spanish/English manuals, remote diagnosis, spare-part list and on-site installation are available for overseas buyers.
