The 32oz PET plastic cup has become a workhorse size across the beverage industry — large enough for iced coffee, bubble tea, smoothies, and beer service, yet still light, stackable, and crystal clear. Behind that simple form sits a specific set of material and manufacturing decisions: PET resin selection, wall thickness, thermoforming tolerances, and lid compatibility all determine whether a cup performs reliably at scale.
1. What Is a 32oz PET Plastic Cup?
A 32oz PET plastic cup is a large-format, thermoformed drinking cup made from polyethylene terephthalate (PET) resin, sized to hold roughly 32 fluid ounces (about 950ml) of liquid plus ice. Its defining characteristics are optical clarity, rigidity relative to its light weight, and compatibility with standard flat and dome lids. Full specifications for Gaokai's standard offering are documented on the 32oz PET Plastic Cups product page.
2. Why PET? The Material Science
PET is a thermoplastic polyester chosen for food packaging because it combines high optical clarity with good mechanical strength and a favorable strength-to-weight ratio. Unlike polystyrene, PET resists cracking and shattering under normal handling, and unlike some polyolefins, it holds a sharp, glass-like transparency that showcases layered drinks, fruit teas, and carbonated beverages. It is also inherently food-safe and widely accepted in recycling streams, which is why PET dominates the large-format cold-beverage cup category.
3. Technical Specifications
The table below reflects the standard specification for Gaokai's 32oz PET cup, item GK107/32C-B.
| Item No. | Capacity | Weight | Caliber | Bottom | Height | Packing |
|---|---|---|---|---|---|---|
| GK107/32C-B | 32oz | 21.0g | 107.4mm | 58.0mm | 178.0mm | 25pcs×12 sleeves, 500pcs/carton |
The 107mm caliber places this cup within Gaokai's mainstream lid-compatible sizing range, which spans 78/90/92/95/98/107/117mm across its full cup lineup — see the Product catalog for the complete caliber and capacity matrix.
4. Manufacturing Process
32oz PET cups are produced through a thermoforming process: PET sheet is heated to a pliable state, then formed under vacuum or pressure into the cup cavity mold, trimmed, and stacked. Consistency at this stage determines two things buyers care about most — uniform wall thickness (which affects rigidity and prevents thin spots) and dimensional accuracy at the rim (which determines lid seal quality). Gaokai's production integrates rational mold design, high-transparency raw material control, and advanced flip-mold forming equipment, detailed on the Technical Equipment section of the Why Choose Us page.

7. PET vs PLA vs RPET Cups
Not every large-format cup application calls for standard PET. Gaokai also manufactures PLA and RPET alternatives, each suited to different priorities.
| Material | Source | Best For | Learn More |
|---|---|---|---|
| PET | Virgin petroleum-based resin | Maximum clarity, cost-efficiency, general beverage use | PET Series |
| PLA | Plant-based (corn starch) bioplastic | Compostable-focused brands and markets | PLA Series |
| RPET | Recycled PET resin | Brands prioritizing recycled-content sourcing | RPET Series |
8. Recyclability & Sustainability
PET is one of the most widely accepted plastics in municipal recycling programs globally, generally identified by resin identification code 1. According to the U.S. Environmental Protection Agency (EPA), PET containers remain among the more commonly recycled plastic packaging types in the United States. Gaokai's production is backed by ISO 9001, ISO 14001, and GRS (Global Recycled Standard) certifications, along with SGS-verified testing — see the Certification section of the About Us page for the full list.
9. Frequently Asked Questions
Are 32oz PET cups suitable for hot beverages?
PET cups are primarily designed for cold and ambient-temperature beverages; for hot drinks, a heat-resistant material or double-wall construction is generally recommended instead.
What lid types fit a 32oz PET cup?
Lid compatibility is determined by the cup's caliber (rim diameter) — the GK107/32C-B's 107.4mm caliber pairs with Gaokai's matching flat and dome lid options within the same caliber family; confirm exact lid part numbers with the sales team for a guaranteed fit.
Can these cups be custom printed with a logo?
Yes — Gaokai offers customized cup printing and can produce to customer drawings or samples; see Product Advantages for more on customization capability.
What is the standard packing configuration?
The GK107/32C-B ships at 25 pieces per sleeve, 12 sleeves per case, for 500 pieces per carton — see Section 3 above for the full specification.
