Why This Matters for Indian Businesses
India generates over 15 billion paper cups annually. The vast majority use PE coating — a plastic film that cannot be recycled in Indian paper mills and is now known to shed thousands of microplastic particles per cup into hot beverages.
PLA-coated cups are marketed as the “eco” alternative, but PLA is classified as plastic by EU regulators, requires industrial composting infrastructure that barely exists in India, and still sheds microplastics under heat and UV stress.
Aqueous coating is the only technology that solves all three problems simultaneously: zero plastic content, zero microplastic shedding, and full recyclability through India’s existing paper mill network — verified by CPPRI, the Government of India’s paper research body.
For businesses with ESG mandates, Zomato/Swiggy sustainability requirements, hospital procurement policies, or corporate sustainability goals, aqueous-coated packaging is the only option that delivers a verifiable, certified zero-plastic claim.
Common Questions
What is the difference between PE, PLA, and aqueous coating on paper cups?+
PE (polyethylene) coating is a plastic film laminated onto paper. It sheds ~25,000 microplastic particles per cup into hot beverages and cannot be recycled with paper. PLA (polylactic acid) is a bioplastic derived from corn or sugarcane but is still classified as plastic by the EU. It sheds microplastics and requires industrial composting unavailable in most of India. Aqueous coating is a water-based barrier with no plastic film — zero microplastic shedding, CPPRI-certified re-pulpable with normal paper waste.
Is PLA better than PE for paper cups in India?+
Not meaningfully. PLA is still plastic (EU-classified), still sheds microplastics under heat and UV stress, and requires industrial composting infrastructure that barely exists in India. It's marketed as eco-friendly but in practice ends up in landfills where it persists for decades. Aqueous coating is the only coating type with zero plastic content and CPPRI recycling certification for India's existing infrastructure.
Which paper cup coating is safest for hot beverages?+
Aqueous-coated cups are the safest for hot beverages. PE cups shed thousands of microplastic particles at temperatures above 85°C. Some PLA formulations can deform above 60°C. Aqueous coating is chemically stable up to 100°C with zero plastic migration or microplastic shedding.
Can PE or PLA paper cups be recycled in India?+
No. PE-coated cups contaminate paper recycling streams because the plastic film cannot be separated from paper in standard mills. PLA cups have the same problem — and composting infrastructure for PLA is not available at scale in India. Only aqueous-coated cups (CPPRI certified) can be recycled alongside normal paper waste in India's existing paper mills.
