Material Composition Assumptions
Plastic food storage containers typically consist of polypropylene as the primary material, comprising approximately 85% of the total weight at 85 grams for a standard 1-liter container. Additional components include polyethylene sealing rings and gaskets accounting for 10% of weight at 10 grams, and small amounts of colorants or additives representing the remaining 5% at 5 grams. Some containers may incorporate polyethylene terephthalate for transparent sections or polystyrene for lightweight applications. Emerging bioplastic variants using polylactic acid remain a small market segment with different end-of-life considerations.
Manufacturing Geography
China dominates global plastic food container manufacturing due to established polymer processing infrastructure and proximity to raw material suppliers. The country’s manufacturing grid operates at 555 gCO2/kWh, reflecting the continued reliance on coal-fired power generation despite renewable energy expansion. This carbon-intensive electricity mix significantly influences the manufacturing phase emissions, particularly during polymer melting, injection molding, and facility operations. Secondary manufacturing hubs in Southeast Asia and Eastern Europe serve regional markets but represent smaller production volumes.

Provenance Override Guidance
-
Submit detailed material composition data including specific polymer grades, recycled content percentages, and additive formulations with supplier certifications.
-
Provide manufacturing facility location with actual electricity consumption data and renewable energy procurement agreements or power purchase arrangements.
-
Document transportation logistics including shipping distances, modal split between ocean freight and trucking, and container utilization rates for distribution networks.
-
Supply end-of-life management data including regional recycling infrastructure availability, mechanical recycling rates, and waste-to-energy recovery factors.
-
Furnish production efficiency metrics including material yield rates, manufacturing energy intensity per unit, and quality control rejection percentages.
Methodology Notes
- The CCI score represents cradle-to-grave emissions for a single-use plastic food storage container including raw material extraction through end-of-life disposal
- Scope 3 dominates at 80% due to upstream polymer production and downstream transportation being outside direct manufacturing control
- Functional unit assumes a 100-gram container with standard 1-liter capacity used once before disposal
- Excludes food waste prevention benefits that containers provide during storage and transport phases
- Data gaps exist for emerging bioplastic alternatives and chemical recycling pathways currently under development
- Regional recycling rate variations from 9% to 54% create significant uncertainty in end-of-life impact calculations
