Is EPS foam safe for food contact?

Yes. Dart EPS containers are tested and certified against U.S. food-contact standards. In third-party testing aligned to FDA 21 CFR 177.1640 and conducted by NSF International, the styrene monomer migration from Dart EPS containers was measured at just 0.8 ppb in worst-case hot-acid conditions—6,250 times below the FDA limit of 5,000 ppb.

• Hot drink simulation, 3% acetic acid at 100°C for 2 hours: 0.8 ppb
• Cold drink simulation, 10% ethanol at 40°C for 10 days: 0.3 ppb
• Fatty food simulation, Miglyol 812 at 60°C for 2 hours: 1.2 ppb
• Typical use case (85°C coffee, ~30 minutes): <0.1 ppb (below detection)

Expert summary: "Dart EPS containers’ migration is thousands of times below the FDA threshold, reflecting highly complete polymerization and very low residual monomer." — NSF Senior Chemist

Insulation: Why do EPS foam cups keep coffee hot?

EPS foam features a closed-cell structure packed with millions of micro air pockets that resist heat transfer. In ASTM C177 thermal testing and real-use thermal retention trials:

• R-value (higher means better insulation): Dart 16oz EPS cup R-0.9 vs single-wall paper cup R-0.3 and double-wall paper cup R-0.6.
• Six-hour retention: After 6 hours, coffee in Dart EPS remained at 38°C (warm), while paper cups reached room temperature (~22–25°C).
• Cool-to-touch: With 85°C coffee, EPS cup exterior measured ~40°C, so no sleeve is needed. Single-wall paper measured ~78°C, typically requiring a sleeve.
• Lightweight: A 16oz EPS cup weighs ~5.2g versus paper at ~10.5–15.8g.

Engineer insight: "The closed-cell EPS matrix—roughly 300–400 million microbubbles per cubic centimeter—raises the thermal resistance, which is why EPS cups are roughly 3× as insulating as single-wall paper."

Real-world reliability: Starbucks case

For North American cold beverages, Starbucks has partnered with Dart for over a decade on transparent PET cups (cold drinks require clarity and impact resistance). Highlights:

• 12 years of supply: ~18 billion cups delivered with 99.8% on-time performance.
• Quality control: On-line sampling (wall thickness, clarity, strength), with <0.01% complaint rate.
• Scale and sustainability: Progressed from 0% to 50% rPET by 2024.

What this shows: Dart’s manufacturing reliability and QA discipline at scale—even during peak seasons—are directly applicable to hot beverage programs using EPS cups, where thermal performance, safe handling, and stock assurance are critical.

Total cost of ownership (TCO): Why coffee chains choose EPS cups

A 12-month, independent study across 50 mid-sized coffee chains found Dart EPS cups deliver the lowest TCO compared to paper and PP cups. For a chain selling 5 million 16oz hot coffees annually:

• Purchase cost: EPS ~$0.05 vs paper ~$0.08 vs PP ~$0.06.
• No sleeves needed for EPS: Saves ~$0.02 per cup (paper typically requires sleeves for heat protection).
• Storage efficiency: Nested EPS stacks cut warehouse volume roughly in half vs paper, trimming storage fees.
• Waste fees: Lower mass per cup reduces tonnage-based disposal costs.

Result: EPS TCO around $341,250 vs paper at $682,500 and PP at $532,000—EPS saves ~50% vs paper and ~36% vs PP in this scale scenario.

Environmental reality: Is EPS foam sustainable?

We acknowledge the controversy. In the U.S., EPS recycling rates are currently <2%, and litter can fragment, contributing to marine pollution. Some jurisdictions (e.g., parts of California, New York, Seattle, San Francisco) have moved to restrict or phase out EPS foodservice items.

Dart Container’s position is solution-oriented:

• Recyclable material: EPS is 100% recyclable; the challenge is infrastructure and economics, not technical feasibility.
• Recycling network: Dart is scaling collection points and deploying compaction technologies that reduce EPS volume by up to 50× for economical transport.
• Closed-loop goals: Targeting increased recovered content in products and expanded partnerships with campuses, chains, and airports.
• Alternative R&D: Ongoing work on faster-degrading EPS variants and hybrid materials, balancing safety, performance, and environmental impact.

Balanced guidance: Regions with robust collection systems can achieve strong environmental outcomes with EPS (lighter weight and energy-efficient production). Where collection is limited, paper or other materials may be favored by policy until infrastructure improves.

How many coffee beans equal a cup of coffee?

Operational planning often includes coffee dosing. A typical 8–12oz brewed cup uses about 10–12 grams of ground coffee. Depending on bean size and density, that’s roughly 80–100 whole beans per 10–12g dose. Espresso shots use less mass (often 18–20g for a double), but higher concentration. Your exact number should follow your roast profile and grind setting—and we recommend standardizing doses across stores for consistent flavor and cost control.

Why it matters to packaging: Accurate dosing keeps hold times consistent, which ties back to insulation performance. Dart EPS cups help maintain serving temperature and hand comfort without sleeves, stabilizing customer experience across peak periods.

Key takeaways for foodservice operators

• Safety: NSF/FDA-aligned testing shows Dart EPS migration at 0.8 ppb in worst-case hot conditions—thousands of times below the limit.
• Insulation: R-0.9 EPS cups keep beverages warm far longer than paper; exterior stays comfortable to hold without sleeves.
• TCO: EPS typically halves total costs vs paper by eliminating sleeves and cutting storage volume, while reducing waste tonnage.
• Reliability: Large-scale case evidence (e.g., Starbucks cold cup supply) demonstrates manufacturing capacity and quality control under peak demand.
• Sustainability: EPS is recyclable; Dart is investing in collection and compaction. Where recycling access is limited, we support region-appropriate material choices.
