TCPL Packaging shifts into lithium-ion battery separator film manufacturing amid rapid growth prospects

Shares of TCPL Packaging surged nearly 16% after the company announced plans to venture into lithium-ion battery separator film production, signalling a strategic shift into India’s fast-growing clean-energy supply chain.

TCPL Packaging Ltd shares jumped sharply after the company said it was moving into lithium-ion battery separator film manufacturing, a decision that would take it beyond its core packaging business and into a fast-growing part of India’s clean-energy supply chain. Trade Brains reported that the stock rose by nearly 16% as investors reacted to the proposed venture, which would be housed in a wholly owned subsidiary now being incorporated.

The company plans to invest about ₹125 crore over the next 18 months, funding the project through a mix of debt and internal accruals. Commercial production is targeted for the fourth quarter of FY28, with the first phase expected to produce 70 million square metres a year, enough to support 6-8 GWh of battery-cell capacity. TCPL eventually aims to scale that to about 500 million square metres, enough for roughly 50 GWh of annual cell capacity, according to the Trade Brains report. Industry estimates cited in the same report suggest battery storage demand in India could top 200 GWh by 2032, underlining why separator films are attracting fresh attention.

The move marks a notable strategic shift for a company best known for paperboard and flexible packaging. Trade Brains said TCPL has spent three decades building a revenue compound annual growth rate of about 17%, largely through packaging lines that now span cartons, printed blanks, litho-lamination, plastic cartons, blister packs and shelf-ready packaging across 10 manufacturing sites. Management is presenting the battery-film venture as an extension of its experience in speciality films, polymer processing and precision manufacturing, even though the new product serves a very different end market.

The stock market reaction also came against a backdrop of stronger quarterly numbers. Trade Brains reported consolidated revenue of ₹493 crore in Q1 FY27, up 16% from a year earlier, while net profit rose 79% year-on-year to ₹40 crore. The report attributed much of the improvement to a sharp fall in finance costs, which nearly halved to ₹12.28 crore from ₹26.44 crore a year earlier. That compares with revenue of ₹453.83 crore and net profit of ₹21.72 crore in the preceding quarter, according to Business Standard’s review of the company’s Q4 FY26 results.
