Our systems are manufactured to withstand heavy duty industrial operations, serving packaging clients worldwide.
Authoritative Insights into Plastic Sheet Extrusion Technologies, Packaging Automation, and supply Chain Optimizations.
The global film and sheet extrusion industry is undergoing a massive transformation driven by functional packaging needs, environmental mandates, and automation goals. Multi-layer co-extrusion technology has become the baseline requirement for producing high-barrier sheets used in modified atmosphere packaging (MAP), medical device protection, and consumer goods. Modern polymer processing demands exact temperature control, minimal shear stress, and stable melt flows.
Historically, European and North American companies led high-end machine construction. However, high capital requirements and lengthy delivery times have shifted global procurement patterns. Global manufacturers are actively seeking partners who can supply reliable, high-output cast sheet lines that process complex polymers (PP, PET, PS, PLA, and high-barrier EVOH co-extrusions) at competitive investment levels.
Wenzhou (specifically Pingyang and Ruian regions) is recognized globally as the center of plastic sheet processing and thermoforming machinery. This geographical concentration delivers distinct engineering advantages:
High Integration: Our location allows us to source specialized alloy steel, heating elements, servo drives, and custom pneumatic components within a very tight geographic radius. This lowers logistical costs and reduces time-to-market.
Skilled Labor Force: The regional ecosystem supports generations of technicians, programmers, and mechanical design engineers who have spent decades perfecting polymer extrusion techniques, die head geometry, and cooling roll designs.
Operational Flexibility: Wenzhou Yicai Machinery provides customization (color layouts, screw configurations, motor classes) that larger European conglomerates struggle to offer efficiently.
Global procurement officers are moving away from evaluating machinery solely on initial purchase price. The current standard is Total Cost of Ownership (TCO), which includes:

A look inside Wenzhou Yicai Machinery's production spaces and manufacturing facilities
Our core product lines are designed to form a complete, automated ecosystem from raw polymer resin to finalized packaging.
High-speed curved dry offset printing systems up to 8 colors.
Automatic counting, stacking, and poly-bag sealing machinery.
Custom aluminum and steel molds with water-cooling channels.
Forming, punching, cutting, and stacking integration.
Heavy-duty servo-driven forming systems for PP/PET/PS/PLA.
Multi-layer co-extrusion flat die systems for packaging sheets.
Our quality assurance protocols start at raw material inspection. We test the hardness and metallurgical properties of our extruder screws and T-dies before machining begins. Once assembled, every thermoforming machine and extrusion line runs for a minimum of 48 hours to check thermal stability, PLC software integration, and pneumatic/hydraulic system pressures.
All main steel and electronic parts are documented and traceable.
We analyze plastic sheet materials (PP, PS, PET, PLA, EVOH), target output thicknesses, and plant height constraints to engineer optimal extruder configurations. After shipping, we provide layout diagrams, schematic files, and video configuration help to simplify installation.
Remote PLC diagnostic connections help quickly resolve operation issues.
Our machinery supports dynamic packaging production across the food service, agricultural, and industrial supply sectors.
As polymer sciences evolve, processing equipment must adapt. We focus our engineering efforts on three primary industrial development paths:
Consumer demand and single-use plastic regulations are accelerating the transition toward biodegradable materials like Polylactic Acid (PLA). PLA is highly sensitive to heat and moisture. Processing it requires customized screw profiles with optimized L/D (length-to-diameter) ratios, precise cooling rates on the polishing rolls, and responsive temperature controls to prevent material degradation. Our latest extrusion lines are optimized to process both fossil-based and bio-based plastics on the same platform.
Single-layer plastic sheets often lack the barrier properties required for food packaging. Our co-extrusion blocks allow clients to create three-layer, five-layer, or seven-layer structures (e.g., PP/AD/EVOH/AD/PP). This approach keeps food fresh longer, cuts down on preservative use, and reduces material costs by utilizing recycled polymer regrind in the center layer.
Connecting manufacturing steps reduces handling labor and keeps contamination risks low. An integrated Yicai setup runs raw granules through the sheet extruder, routes the sheet into the thermoforming mold, punches out the shapes, sends the skeletons to the online crusher, and directs the finished products to the offset printer and automatic packager. This complete system runs with minimal operator intervention.
Expert answers to common questions about polymer processing, machine setup, and equipment procurement.
Our sheet extruders process a wide range of thermoplastics, including Polypropylene (PP), Polystyrene (PS), Polyethylene (PE), Polyethylene Terephthalate (PET), and Polylactic Acid (PLA). We configure the screw design, melt pumps, and die structures based on the target material's rheology and flow properties.
We use precise T-dies with micro-adjustment screws and clothing bar systems. For high-precision configurations, we integrate melt pumps to maintain a steady output pressure. This prevents thickness fluctuations caused by variations in screw feed speed or raw material consistency.
Our Sheet Machine Edge Material Online Crusher grinds trim and scrap skeletons automatically, feeding the material directly back to the extruder. This design keeps the scrap clean, prevents contamination, and reduces material waste during long runs.
Dry offset printing (like our 6-Color and 8-Color Curved Offset Machines) is optimized for printing on preformed plastic cups at high speeds. It applies all colors in a single pass to a rubber blanket, transferring the complete design to the cup surface with precise alignment.
Our thermoforming systems are built to standard platen dimensions with flexible clamping options. This design allows you to install and align existing molds, though we recommend using Yicai molds for optimal water-cooling and cycle speeds.
Standard extrusion and thermoforming configurations are completed within 45 to 60 days. Custom lines with complex co-extrusion setups, custom molds, or multi-station requirements generally take 75 to 90 days, including comprehensive testing before shipment.
