Watch a used 120 PP/PS sheet extrusion line testing PP sheet roll production for a customer project, helping buyers verify roll quality before shipment.
For buyers planning plastic cup, food container, tray or thermoforming production, the sheet extrusion line is the upstream equipment that decides whether the downstream forming machine can run smoothly. If PP sheet roll quality is unstable, the cup making machine or thermoforming machine will also face forming defects, cutting problems and material waste.
This video shows a used 120 PP/PS sheet extrusion line testing PP sheet roll production for a customer. The purpose of this test is to confirm that the used sheet extrusion line can produce usable PP roll material before delivery discussion, helping the buyer reduce purchase risk.
Why PP Sheet Roll Testing Matters
A sheet extrusion line should not be evaluated only by machine photos. Buyers need to see whether the line can actually produce sheet rolls with stable running condition.
For a used PP/PS sheet extrusion line, the buyer should pay attention to:
- Whether the extruder can run under test condition
- Whether the PP material can be melted and formed into sheet
- Whether the sheet roll is continuous and usable
- Whether the cooling and winding process is stable
- Whether the sheet can support downstream cup or thermoforming production
- Whether the supplier can provide real video confirmation before shipment
A real PP roll testing video gives overseas buyers stronger evidence than a simple equipment list.
What Is a Used 120 PP/PS Sheet Extrusion Line?
A PP/PS sheet extrusion line is used to process plastic raw material into sheet rolls. These rolls are then used by downstream equipment such as plastic cup making machines, three-station thermoforming machines, vacuum forming machines or lid forming machines.
The user-provided machine information identifies this as a used 120 PP/PS sheet extrusion line. In practical project matching, the final configuration still needs to be checked according to material, sheet width, sheet thickness, output target and downstream product type.
Suitable Downstream Applications
PP and PS sheet rolls can be used for many disposable plastic packaging products, depending on material formula, sheet thickness and mold design.
Typical downstream applications include:
- Disposable plastic cups
- Food containers
- Plastic trays
- Cup lids
- Fruit boxes
- Takeaway packaging
- Thermoformed packaging inserts
- Other PP or PS thermoformed plastic products
If the buyer mainly produces deep round cups, the sheet roll should be matched with a plastic cup making machine. If the buyer produces food boxes, trays or lids, the sheet roll may be matched with a three-station thermoforming machine.
Used Sheet Extrusion Line Buying Points
When buying a used sheet extrusion line, buyers should confirm more than the screw size. The real value depends on whether the machine can match the buyer's production plan.
Important checking points include:
- Material type: PP, PS or other material
- Target sheet width
- Sheet thickness range
- Roll quality and winding stability
- Screw and barrel condition
- Die head condition
- Three-roll cooling and calendering condition
- Electrical cabinet and temperature control status
- Downstream machine type: cup machine, thermoforming machine or vacuum forming machine
- Whether test video and loading confirmation can be provided
The testing video is especially important because used sheet extrusion equipment must be checked under real running condition whenever possible.
How It Fits a Complete Production Line
A used PP/PS sheet extrusion line can be purchased as upstream equipment for a complete plastic packaging production line. It can help buyers control sheet supply, material cost and roll quality instead of relying only on external sheet suppliers.
A complete production direction may include:
- PP/PS sheet extrusion line
- Plastic cup making machine or three-station thermoforming machine
- Product mold
- Chiller
- Air compressor
- Crusher and recycling support
- Packing and stacking support
For buyers building a long-term factory project, the sheet extrusion line should be selected together with the final product and downstream forming machine.
What Buyers Should Confirm Before Quotation
Before quotation, buyers should send:
- Final product photo or drawing
- Material: PP, PS, PET or other
- Required sheet width
- Sheet thickness range
- Target output or daily production plan
- Downstream machine type
- Factory voltage and destination country
- New or used machine preference
With these details, WEIXIN Machinery can help check whether this used 120 PP/PS sheet extrusion line is suitable, and whether it should be matched with a cup making machine, thermoforming machine, vacuum forming machine or complete production line.
FAQ
What is this used 120 PP/PS sheet extrusion line for?
It is used to produce PP or PS sheet rolls for downstream plastic cup, food container, tray, lid or thermoforming production.
Why is PP roll testing important before shipment?
Testing helps confirm that the used sheet extrusion line can run and produce usable sheet roll material. For overseas buyers, a real testing video helps reduce purchasing risk.
Can this line be matched with a plastic cup making machine?
Yes. PP or PS sheet rolls are commonly used before cup making machines. The sheet width, thickness and roll quality must match the cup product and machine requirement.
Can this line be used for thermoforming machines?
Yes. PP/PS sheet rolls can supply three-station thermoforming machines or vacuum forming machines for food containers, trays, lids and other plastic packaging products.
Need a Used PP/PS Sheet Extrusion Line?
If you are looking for a used PP/PS sheet extrusion line for plastic cup, food container, tray or thermoforming production, send your product photo, required sheet width, sheet thickness, material and target output. WEIXIN Machinery can help check the right sheet extrusion line, downstream machine and complete production line direction before quotation.
