Whether you operate a busy food-service counter, organise outdoor events, or source disposable drinkware at scale, 16oz plastic cups represent one of the most versatile and cost-effective solutions on the market. This guide breaks down everything you need to know — from raw-material science and dimensional tolerances to sustainability certifications and bulk purchasing — drawing on the manufacturing expertise of Zhejiang Gaokai New Material Co., Ltd., a leading food-container producer based in Haining City, Zhejiang Province, China.
A 16-ounce (oz) plastic cup holds approximately 473 ml of liquid — the standard "medium" or "large" serving size at cafés, fast-food outlets, and sporting venues worldwide. The cups are injection-moulded or thermoformed from food-grade thermoplastic resins, giving them a crystal-clear appearance, lightweight feel, and the structural integrity needed for both cold and room-temperature beverages.
Gaokai's GK92/16C model is a representative example of industry-standard engineering:
| Item No. | Product Name | Capacity | Weight | Caliber (Top Ø) | Bottom Ø | Height | Pcs / Sleeve | Qty / Carton |
|---|---|---|---|---|---|---|---|---|
| GK92/16C | 92 / 16oz Cup | 16 oz (473 ml) | 13.5 g | 92.3 mm | 57.0 mm | 131.6 mm | 50 pcs × 20 sleeves | 1,000 pcs |
These precise dimensions ensure stackability, secure lid fitment, and compatibility with standard cup-holder apertures — critical factors for foodservice operators and event planners alike.
The performance and environmental profile of a 16oz plastic cup is largely determined by its resin. Gaokai offers three distinct material lines, each suited to different operational and sustainability requirements:
| Material | Full Name | Key Properties | Typical Use Case | End-of-Life |
|---|---|---|---|---|
| PET | Polyethylene Terephthalate | High clarity, impact-resistant, BPA-free | Cold drinks, bubble tea, smoothies | Recyclable (resin code #1) |
| PLA | Polylactic Acid | Bio-based, compostable, lower carbon footprint | Eco-events, green-certified F&B outlets | Industrially compostable |
| RPET | Recycled PET | Same clarity as virgin PET, up to 100% recycled content | Sustainability-focused brands | Recyclable; circular economy |
Bisphenol A (BPA) is an industrial chemical historically used in some plastics. All three of Gaokai's resin lines are inherently BPA-free, meaning no BPA is introduced at any stage of production. This is a baseline requirement for food-contact compliance under EU Regulation (EU) No 10/2011 and FDA 21 CFR standards.
Modern 16oz plastic cups are far more than simple cylinders. Thoughtful engineering decisions at the design stage determine user experience, branding flexibility, and supply-chain efficiency.
A smooth, outward-rolled rim eliminates sharp edges and provides a comfortable, splash-resistant drinking experience. It also creates a reliable sealing surface for dome or flat lids — essential for to-go beverages.
The 92.3 mm top / 57.0 mm bottom geometry of the GK92/16C gives a taper angle that allows cups to nest tightly in sleeves of 50. This reduces warehouse footprint and freight costs significantly when ordering by the carton (1,000 pcs).
At just 13.5 g per cup, material is distributed precisely where structural loads occur — around the base and upper rim — while maintaining a thin wall profile that keeps the cup lightweight and cost-competitive.
PET and RPET cups offer glass-like optical clarity, showcasing the colour and texture of the beverage inside. Custom printing and sleeve labelling are compatible with all standard offset and flexographic processes, enabling brand differentiation without tooling changes.
Technical Note: Gaokai operates advanced thermoforming equipment capable of holding dimensional tolerances to ±0.2 mm across all critical measurements (caliber, height, bottom diameter). Learn more at Technical Equipment.
The 16oz format occupies a sweet spot between convenience and capacity. Below are the primary commercial contexts where these cups deliver the highest value:
| Sector | Application | Recommended Material |
|---|---|---|
| Quick Service Restaurants (QSR) | Fountain sodas, iced coffee, lemonade | PET |
| Bubble Tea & Specialty Drinks | Boba, fruit teas, smoothies | PET / RPET |
| Stadiums & Arenas | Beer, soft drinks, sports drinks | PET |
| Corporate Events & Catering | Branded still/sparkling water, mocktails | RPET (sustainability reporting) |
| Eco-Certified Venues & Festivals | Any cold beverage | PLA (compostable waste stream) |
| Retail & Grocery | Party packs, seasonal promotions | PET / RPET |
Sustainability is no longer optional in the food-packaging industry. Gaokai's RPET Series and PLA Series directly address the growing demand from retailers and governments for reduced virgin-plastic consumption.
RPET cups divert post-consumer plastic bottles from landfill, closing the recycling loop.
PLA cups are derived from renewable plant starch and meet EN 13432 / ASTM D6400 industrial composting standards.
PET cups carry resin code #1, meaning they are accepted in most curbside recycling programmes globally.
All products are manufactured under certifications detailed at Gaokai's Certification page.
| Cup Size | Volume (ml) | Typical Caliber | Best For | Gaokai SKU |
|---|---|---|---|---|
| 7 oz | 207 ml | 78 mm | Espresso, water, tasting portions | GK78/07C |
| 8 oz | 237 ml | 78 mm | Coffee, juice, small cold drinks | GK78/08C-B |
| 10 oz | 296 ml | 78 mm | Standard cold drinks, children's sizes | GK78/10C |
| 16 oz | 473 ml | 92 mm | Large cold drinks, events, QSR | GK92/16C |
| U-Shape 360 ml | 360 ml | 90 mm | Bubble tea, ice cream | GK90/360UC |
| U-Shape 500 ml | 500 ml | 90 mm | Dessert drinks, large smoothies | GK90/500UC |
Purchasing 16oz plastic cups in volume requires attention to several procurement variables beyond unit price:
MOQ (Minimum Order Quantity): Standard cartons contain 1,000 pcs (50 pcs × 20 sleeves), making per-unit economics highly attractive from the first pallet.
Lead Time: Gaokai responds to inquiries within 12 business hours, with production scheduling confirmed promptly thereafter.
Customisation: Logo printing, custom rim colours, and bespoke sizing are available. Gaokai operates dedicated tooling for customer-specific drawings.
Logistics: Tight nesting (1,000 pcs/carton) maximises container utilisation — a direct saving on FOB shipping costs.
Certifications: Ensure your supplier holds food-contact safety approvals. Review Gaokai's certifications for compliance documentation.
Zhejiang Gaokai New Material Co., Ltd. is a vertically integrated food-container manufacturer headquartered at No. 38, Xianxia Road, Jianshan New District, Haining City, Zhejiang Province. The company produces and sells its entire range in-house — from raw material processing through thermoforming, quality inspection, and international logistics.
Key differentiators include:
Three distinct product lines: PET, PLA, and RPET
In-house advanced thermoforming equipment
Established global sales network across Asia, Europe, and the Americas
Strong product advantages including BPA-free materials, optical clarity, and consistent dimensional accuracy
PET and RPET cups are designed for cold and room-temperature beverages only and should not be used in microwave ovens. PLA cups are similarly unsuitable for high heat due to their lower glass-transition temperature (approximately 55–60 °C).
These cups are optimised for cold service. For hot drinks, a double-wall or insulated format is recommended. Contact Gaokai's team to discuss your specific temperature requirements.
The GK92/16C features a 92 mm top caliber, compatible with standard 92 mm flat lids and dome lids widely available in the market. Custom lid solutions can be developed upon request.
Gaokai replies to all inquiries within 12 working hours. Submit your inquiry now to start the process.
