(1) Market size
The annual output value of the plastic extrusion industry in South Korea is about 5.5 trillion Korean won (approximately 4 billion US dollars), accounting for over 30% of the country's plastic processing industry.
Main application areas:
Packaging industry (40%): food, medicine, cosmetic films, preforms, etc.
Construction industry (25%): PVC pipes, door and window profiles, waterproofing membranes.
Automotive industry (20%): Lightweight plastic components (dashboard, bumper, interior).
Electronics industry (15%): cable sheaths, insulation materials, precision plastic parts.
(2) Main enterprises
LG Chem: The largest plastic raw material supplier in South Korea, providing high-performance engineering plastics.
SK Chemicals: Focusing on environmentally friendly plastics (such as PCR recycled materials).
Hanwha Solutions: produces PVC and composite plastic building materials.
Small and medium-sized enterprises: concentrated in industrial zones such as Busan and Incheon, mainly supplying local and export markets.
2. Growth drivers
(1) The trend of automotive lightweighting
The growing demand for electric vehicles (EVs) is driving the application of engineering plastics such as PP (polypropylene), ABS (acrylonitrile butadiene styrene), and PC (polycarbonate) in automotive components.
Korean car companies (Hyundai, Kia) are increasing the proportion of plastic replacing metal to reduce vehicle weight and improve range.
(2) High end demand in the electronics industry
The semiconductor and display panel industries require high-precision plastic extruded parts, such as optical grade PC films and 5G antenna covers.
The South Korean government is promoting the "K-semiconductor strategy" to drive demand for related plastics.
(3) Upgrading the packaging industry
The demand for high barrier films (extending shelf life) in the food and pharmaceutical industries has increased.
Environmentally friendly packaging (recyclable and biodegradable materials) has become a new trend.
3. Main challenges
(1) Tightening environmental regulations
The revision of the South Korean Resource Recycling Act in 2022 requires plastic companies to increase the proportion of recycled materials used (2025 target: 30%).
Disposable plastic restrictions: Starting from 2023, the use of PVC straws and foam plastic tableware will be prohibited, affecting the market for some extruded products.
Carbon reduction pressure: The South Korean government plans to reduce greenhouse gas emissions by 40% by 2030, and the plastic industry needs to optimize energy use.
(2) Fluctuations in raw material prices
Affected by international oil prices and geopolitical factors, the prices of petrochemical raw materials such as PE (polyethylene) and PP (polypropylene) fluctuate greatly, affecting the profits of enterprises.
(3) International competition intensifies
Chinese extrusion machinery such as Jinwei and Bellrock have high cost-effectiveness and are seizing the mid to low end market in South Korea.
Japanese and German companies still have advantages in high-end extrusion technologies such as multi-layer co extrusion and microcellular foaming.
4. Technological development trends
(1) High precision extrusion technology
Micro layer Coextrusion: Used for high-end applications such as optical films and battery separators.
Thin wall extrusion: suitable for food packaging and medical catheters.
(2) Green extrusion technology
Recycled Plastic (PCR) Extrusion: LG Chem and SK Chem have launched dedicated extrusion lines for recycled PET (rPET) and recycled HDPE (rHDPE).
Application of bio based plastics: PLA (polylactic acid) and PHA (polyhydroxyalkanoates) are being tested in the packaging industry.
(3) Intelligence and automation
AI quality control: using machine learning to detect defects in extruded products (such as uneven thickness and bubbles).
Internet of Things (IoT) monitoring: Real time adjustment of extruder parameters to improve energy efficiency.
5. Future prospects
High end: Korean companies will focus on high value-added products such as automotive lightweight materials and electronic grade plastics.
Circular economy: The government and enterprises cooperate to promote the plastic recycling system, and the recycled plastic market is expected to grow by 8-10% annually.
Export opportunities: The demand for infrastructure in Southeast Asia (Vietnam, Thailand) is growing, and South Korea has great potential for exporting building materials (such as PVC pipes).
