TCPL Packaging invests ₹125 crore in lithium-ion battery separator films
TCPL Packaging has entered the lithium-ion battery separator film market with a ₹125 crore investment approved by its Board on August 11, 2026. The new subsidiary will achieve commercial production by early 2028, initially supporting 6-8 GWh of battery cell capacity. This strategic move leverages TCPL's core capabilities in polymer processing and aligns with India's domestic battery manufacturing goals under the PLI scheme.

TCPL Packaging has formally approved its entry into the Advanced Chemistry Cell (ACC) battery supply chain, planning to manufacture lithium-ion battery separator films through a newly proposed subsidiary. The Board of Directors, meeting on August 11, 2026, sanctioned an initial investment of ₹125 crore to be deployed over the next 18 months. This strategic diversification aims to capitalize on India’s rapidly growing domestic battery manufacturing ecosystem, with commercial production targeted for early 2028. The move complements the company’s strong Q1FY27 financial performance, where net profit surged 79.2% to ₹40.0 crore.
The project will initially establish a manufacturing facility with an installed capacity of 70 million square meters per annum. This output is designed to support approximately 6-8 GWh of annual lithium-ion battery cell production. TCPL intends to fund the ₹125 crore expenditure through a mix of internal accruals and debt. The execution roadmap includes land acquisition and technology finalization in 2026, followed by facility construction and equipment installation in 2027. Customer qualification and phased ramp-up are scheduled for early 2028 onwards.
Strategic Rationale and Market Context
The decision aligns with significant policy support for domestic battery manufacturing in India, including the ACC Battery Production Linked Incentive (PLI) scheme with an outlay of ₹18,100 crore. The scheme targets 50 GWh of domestic ACC manufacturing capacity, of which 40 GWh has already been awarded. Additionally, a Grid-Scale Battery Programme proposes 10 GWh of domestic manufacturing capacity for stationary energy storage. TCPL’s entry addresses the critical need for localizing separator films, a component that represents only 4-6% of battery cell cost but is vital for safety, energy density, and thermal stability.
| Project Parameter | Detail |
|---|---|
| Investment Amount | ₹125 crore |
| Deployment Period | 18 months (2026-2027) |
| Initial Capacity | 70 million sq. meters per annum |
| Supported Cell Capacity | 6-8 GWh |
| Commercial Production | Early 2028 |
Leveraging Core Capabilities
TCPL Group is leveraging its existing expertise in specialized film processing, advanced polymer handling, and precision manufacturing at scale. The company plans to adopt a wet manufacturing process for separator films, involving backward integration into specialized film manufacturing (Phase II) and coating/conversion (Phase I). Key capabilities being transferred include stringent quality assurance, process control, and R&D in product development. These competencies are essential for producing porous insulating films that prevent electrode contact while enabling lithium-ion flow.
Long-Term Vision
Beyond the initial phase, TCPL envisions scaling its separator film capacity to approximately 500 million square meters per annum over the next 5-7 years. This long-term target would potentially support ~50 GWh of battery cell manufacturing, significantly reducing import dependence. Saket Kanoria, Chairman & Managing Director, emphasized that this move builds on the group’s track record of identifying high-potential opportunities ahead of market curves. The expansion positions TCPL as a key player in India’s indigenous battery value chain, alongside its core packaging businesses.
What the Numbers Show
The ₹125 crore investment represents a modest capital outlay relative to TCPL’s consolidated total income of ₹494.9 crore in Q1FY27, indicating a low immediate financial strain on the parent company. However, the high-risk nature of entering a new technology sector like battery materials requires careful monitoring of execution timelines. The disparity between the initial 6-8 GWh support capacity and the long-term 50 GWh vision suggests a phased, demand-driven scaling strategy rather than an aggressive upfront build-out. Investors should watch for updates on technology partnerships and customer qualification progress in 2027.
