PP/PS/PET Sheet Extrusion Lines

PP, PS and PET sheet extrusion lines produce plastic sheet rolls used as the upstream material for cup making machines, three-station thermoforming machines and vacuum forming machines. For factories making disposable cups, food containers, trays, lids or blister packaging, stable sheet quality is directly connected to forming speed, product weight, wall distribution and final rejection rate.

A sheet extrusion line normally includes raw material feeding, extrusion, melt filtration or metering, calendar rolls, cooling, trimming, winding and thickness control. The correct configuration depends on material type, required sheet width, sheet thickness, output target, layer structure and whether recycled material will be used. PP and PS single-screw lines are widely used for cup and food container production, while PET parallel twin-screw lines are often selected for APET, RPET and PLA sheet where drying, transparency and output stability must be considered.

For plastic cup production, sheet thickness and width must match the cup machine forming area and mold layout. For food containers and trays, sheet rigidity, heating behavior and forming depth are more important. A complete production plan should consider the extruder, thermoforming machine, molds, crusher, mixer, chiller, compressor and workshop layout together instead of choosing each machine separately.

VihoX sheet extrusion lines are supplied as factory-direct equipment and can be matched with downstream thermoforming machines for turnkey plastic packaging production. Voltage, width range, material system and auxiliary equipment should be confirmed before quotation. To recommend the right extrusion line, please send your target product, material, sheet width, thickness range, expected output, downstream machine type and factory voltage.

Quick answers for sheet extrusion line buyers

What does a sheet extrusion line produce? It converts PP, PS or PET resin into plastic sheet rolls that feed cup making machines, three-station thermoformers and vacuum forming machines, controlling width, thickness and surface quality.

Which extruder configuration is right? PP and PS cup and food container production commonly uses single-screw lines, while PET (APET, RPET) and PLA sheet often uses parallel twin-screw lines with drying, to keep transparency and output stable.

How do I match sheet to my forming machine? Sheet width and thickness must fit the cup machine forming area and mold layout; for trays and containers, sheet rigidity, heating behavior and forming depth matter most.

What should I send for a quotation? Target product, material, sheet width, thickness range, expected output, downstream machine type and factory voltage.

VihoX supplies factory-direct extrusion lines, tested before shipment, with voltage customization, width range, material system and auxiliary equipment matched to your project.
