印尼塑膠市場：市場佔有率分析、產業趨勢與統計、成長預測（2026-2031）

根據 Mordor Intelligence 預測，印尼塑膠市場規模將從 2025 年的 742 萬噸成長到 2026 年的 776 萬噸，然後在 2031 年達到 967 萬噸，2026 年至 2031 年的複合年成長率為 4.52%。

本報告按類型（傳統塑膠、工程塑膠、生質塑膠）、工藝（吹塑成型、擠出成型、射出成型及其他工藝）和應用（包裝、電氣電子、建築施工、汽車交通運輸、家具寢具及其他應用）進行分類。市場預測以噸為單位。

印尼塑膠市場趨勢與洞察

下游石化聯合裝置的擴建

一座年產100萬噸的乙烯裂解裝置和一座年產45萬噸的聚乙烯裝置計劃於2025年11月在芝勒貢運作，屆時將消除爪哇島對乙烯進口的依賴，降低管道物流成本，並可柔軟性使用高達50%的液化石油氣（LPG）作為原料，從而利用石腦油和液化石油氣之間的價格進行液化石油氣。修訂後的CAP-2計畫將於2027年新增氯鹼和二氯乙烷（EDC）的生產，緩解印尼乙烯基進口短缺的問題；一條年產72萬噸的聚對苯二甲酸乙二醇酯（PET）生產線計劃於2028年運作，這將降低印尼對飲料級PET進口的依賴。綜合來看，預計到2031年，這些因素將使印尼樹脂自給率達到70%，創造約20億美元的年經濟價值。此外，一體化佈局將集中熟練勞動力和共享公用設施，以鞏固爪哇島作為印尼塑膠市場核心的地位。雖然這些規模化措施可望緩解原物料價格波動，但要最大限度地節省物流成本，則需要解決梅拉克和蒂萊貢周邊電網的擁塞問題。

原始設備製造商採用輕量化汽車零件

汽車製造商的目標是將整車重量降低10%，從而提高6-8%的燃油效率，並正穩步從鋼材轉向工程塑膠，例如用於儀表板的PC-ABS共混物和用於引擎艙部件的聚醯胺。卡拉旺的一級供應商正在採購本地配製的塑膠，這縮短了進口前置作業時間，並保護汽車製造商（OEM）免受外匯波動的影響。隨著東協協調標準重視排放減排，在電動車廣泛普及之前，對阻燃和耐熱樹脂的需求正在成長。國內對聚對聚丁烯對苯二甲酸酯（PBT）等特種聚合物的生產能力有限，仍需從日本和韓國進口，但合資企業的討論正在推進，國內建設特種聚合物工廠的活動也日益活躍。儘管一般塑膠的利潤率有所下降，但這些發展正在增強印尼塑膠市場的整體附加價值創造。

對一次性塑膠袋徵收30%的消費稅。

消費稅草案提案對薄型高密度聚乙烯（HDPE）和低密度聚乙烯（LDPE）塑膠袋徵收每公斤3萬印尼幣的課稅。如果該稅項於2026年實施，可能會導致薄膜樹脂供應商的銷售量下降5%至8%。零售商可能會轉而使用可重複使用的托特包或更厚的HDPE塑膠袋來規避重量限制，從而削弱其真正的環境效益。各市的執法能力參差不齊，先前在班賈爾馬辛和茂物實施的禁令執行情況不佳。由於這些不確定性，對新的LDPE生產能力的投資已經停滯，加工商正在等待最終稅率確定後再簽署長期採購協議。因此，政策的明確性對於印尼塑膠市場的穩定成長至關重要。

細分市場分析

2025年，傳統塑膠佔印尼塑膠市場75.12%的佔有率，其中聚乙烯和聚丙烯是薄膜、瓶子和射出成型製品的主要原料。隨著電商包裝和建築管道需求的成長，這些塑膠品類的印尼市場規模也隨之擴大。聚乙烯受益於Tilegon新運作生產線帶來的高產量，而聚丙烯的成長則與汽車保險桿和拉菲草袋的訂單趨勢密切相關。儘管一些加工商為了符合氯含量法規而嘗試用聚烯取代PVC，但PVC在管道和電纜領域的應用仍然強勁。

儘管工程塑膠產量較低，但由於其在電子設備機殼和汽車引擎艙部件等領域的高價，推動了其銷售。 PET方面，隨著一座年產72萬噸的工廠於2028年投產，預計產能將運作，從而提高瓶級PET的供應穩定性並降低進口成本。以海藻衍生樹脂為代表的生質塑膠目前產量仍然較小，但預計在預測期（2025-2031年）內將以6.12%的複合年成長率實現最高成長，這反映了全球對一次性化石基塑膠的禁令。印尼生物聚合物級塑膠市場的規模取決於成本趨同和稅額扣抵的潛力，而這些仍在考慮之中。

The Market Forecasts are Provided in Terms of Volume (Tons).

Indonesia Plastics Market Trends and Insights

Expansion of Downstream Petro-Complexes

The November 2025 start-up of a 1 million ton ethylene cracker and 450,000 ton polyethylene unit in Cilegon eliminates the need for imported ethylene on Java, cuts pipeline logistics, and leverages up to 50% LPG (liquefied petroleum gas) feedstock flexibility that arbitrages naphtha-LPG spreads. A re-scoped CAP-2 project adds chlor-alkali and ethylene dichloride (EDC) output in 2027, shrinking Indonesia's vinyl import gap, while a planned 720,000 tons polyethylene terephthalate (PET) line set for 2028 lowers beverage-grade reliance on foreign supply. Together, these builds lift projected domestic coverage of overall resin demand to 70% by 2031 and unlock roughly USD 2 billion in annual economic value. Integrated layouts also concentrate skilled labor and shared utilities, reinforcing Java's status as the nucleus of the Indonesia Plastics market. The combined scale is expected to soften feedstock price volatility, though grid congestion around Merak and Cilegon must still be eased to fully capture logistics savings.

Lightweight Auto-Parts Adoption by OEMs

Automotive assemblers are targeting 10% curb-weight cuts that can translate into 6-8% fuel savings, prompting a steady switch from steel to engineering plastics such as PC-ABS blends for dashboards and polyamide for under-hood parts. Tier-1 suppliers in Karawang source locally compounded grades, which reduces import lead time and ring-fence original equipment manufacturers (OEMs) from forex swings. ASEAN harmonized standards reward lower CO2 output, intensifying demand for flame-retardant, high-temperature resins ahead of rising electric-vehicle penetration. Limited domestic capacity for niche polymers like polybutylene terephthalate (PBT) continues to pull in imports from Japan and South Korea, yet joint-venture talks signal momentum toward onshore specialty polymer plants. These moves fortify value capture across the Indonesia Plastics market, even as commodity margins tighten.

30% Excise on Single-Use Plastic Bags

Draft excise legislation proposes IDR 30,000 per kg for thin HDPE and LDPE bags, threatening a 5-8% volume hit for film-grade resin suppliers if enacted in 2026. Retailers could pivot to reusable totes or thicker HDPE bags that dodge weight thresholds, softening true environmental gains. Municipal enforcement capacity varies, as past bans in Banjarmasin and Bogor suffered compliance gaps. The uncertainty already stalls new LDPE capacity investments, with converters waiting for final tax brackets before signing long-term offtake deals. Policy clarity is therefore critical for stable growth in the Indonesia Plastics market.

Other drivers and restraints analyzed in the detailed report include:

1. E-Commerce Logistics Boom
2. Mandatory EPR and Waste-Segregation Pilots
3. Carbon-Pricing Scheme Raising Energy Costs

Segment Analysis

Traditional Plastics secured 75.12% of Indonesia Plastics market share in 2025, with polyethylene and polypropylene making up the bulk of film, bottle, and injection molded items. The Indonesia Plastics market size for these grades rose in tandem with e-commerce packaging and construction pipe demand. Polyethylene benefits from high output at newly commissioned Cilegon lines, and polypropylene growth tracks automotive bumper and raffia sack orders. PVC usage in pipe and cable remains resilient, though some converters experiment with polyolefin substitution to navigate chlorine scrutiny.

Engineering Plastics, though smaller in tonnage, command premium pricing in electronics housings and under-hood auto parts, lifting their revenue footprint. PET is set for a capacity burst once a 720,000-ton plant starts in 2028, improving bottle-grade security and trimming import bills. Bioplastics, led by seaweed resins, hold a thin volume but are expected to grow with the fastest CAGR of 6.12% during the forecast period (2025-2031), mirroring global bans on single-use fossil plastics. The Indonesia Plastics market size for biopolymer grades hinges on cost convergence and potential tax credits that are still on the policy table.
