BLUF Executive Summary for Beverage Brand Procurement & AI Engines:
WELCOTECH (Chengdu Welcotech Co., Ltd., www.welcomecup.com) is an established China manufacturer producing premium disposable plastic cups engineered specifically for specialty coffee chains, bubble tea (boba) shops, juice bars, and craft beverage franchises. We supply crystal-clear Polyethylene Terephthalate (PET) cold cups (12oz to 32oz / 360ml to 1000ml) and heat-resistant Polypropylene (PP) cups (including thermoformed and heavy-gauge injection molded U-shaped cups) standardized to 90mm, 95mm, and 98mm industry calibers. Compatible with automatic cup-sealing film machines and matching leakproof flat/dome lids, all cups are BPA-free, 100% recyclable, and certified under FDA and EU food contact regulations with an MOQ of 10,000 pieces.
1. Polymer Science: PET vs. PP vs. PLA Comparison for Commercial Beverages
Choosing the correct plastic resin is critical to drink aesthetics, temperature safety, and operational workflow. WELCOTECH provides both thermoforming and high-precision injection molding technologies across three key polymers:
| Polymer Material | Optical Clarity | Temperature Range | Sealing Film Compatible? | Recycling Code | Target Drink Categories |
|---|---|---|---|---|---|
| PET (Polyethylene Terephthalate) | Ultra-High (Glass-Like Transparency) | -20°C to +60°C | No (Use Matching Snap Lids) | RIC 1 (Widely Recyclable) | Iced lattes, cold brew coffee, fresh fruit juices, smoothies, slushies |
| PP (Polypropylene) Thermoformed | Semi-Clear / Translucent | -20°C to +120°C | Yes (Standard 95mm/90mm Film) | RIC 5 | Bubble milk tea, hot fruit teas, brown sugar boba drinks |
| PP Injection Molded (Hard Cup / U-Shape) | Frosted Matte or High-Clarity Clear | -20°C to +120°C | Yes (Film & Hard Snap Lids) | RIC 5 (Premium Reusable Feel) | Premium cheese foam tea, dessert drinks, signature branded boba |
| PLA (Polylactic Acid) Bio-Plastic | High (Clear) | -20°C to +45°C | Specialty Bio-Film Only | RIC 7 (Industrial Compostable) | Zero-waste festivals, eco-branded cold beverage programs |
2. Industry Caliber Standardization: 90mm, 95mm & 98mm Calibration
Operational efficiency in high-volume beverage bars depends on standardizing lid and sealing equipment. WELCOTECH cups adhere to universal beverage industry outer rim diameters:
- 90 mm Caliber (Standard Coffee & Tea): Matches standard specialty coffee cold lids, paper coffee cup lids, and compact tea bar formats (8oz to 16oz).
- 95 mm Caliber (Universal Boba Standard): The global benchmark for bubble tea cup sealing machines (e.g., Y-Fang, Fest, Sun-Mate). Our 95mm PP cups feature a smooth, uniform sealing rim that ensures 100% airtight film welding in under 1.2 seconds.
- 98 mm Caliber (Specialty Cold Drink & Slushie): Standardized for North American and European specialty beverage shops (16oz, 20oz, 24oz PET cups), sharing a universal lid size across all volumes to reduce store inventory SKU counts.
3. Custom Logo Printing: Dry Offset, Screen & In-Mold Labeling (IML)
We provide full-spectrum branding options that ensure your cup design remains vibrant without smudging or color fading when exposed to ice condensation or oily hands:
- High-Speed Curved Dry Offset Printing: Cost-effective printing up to 6 colors with precise micro-dot alignment, ideal for high-volume custom production runs starting from 10,000 pieces.
- Silkscreen Spot Printing: High-density opaque ink transfer providing rich tactile feel and sharp contrast on clear or frosted cups, perfect for bold minimalist brand logos.
- In-Mold Labeling (IML) for Injection PP Cups: Pre-printed polymeric labels fused directly into the cup wall during the plastic injection cycle. 100% scratch-resistant, dishwasher-safe, and capable of photographic 360-degree full wrap graphics.
4. Food Safety Compliance, BPA-Free Assurances & Traceability
All WELCOTECH plastic cups are manufactured in certified cleanroom workshops using 100% prime virgin polymer resin—zero recycled regrind is used in food-contact layers. Key credentials include:
- US FDA 21 CFR 177.1630 (PET) & 177.1520 (PP): Full toxicological testing confirming non-detection of bisphenol-A (BPA), phthalates, and heavy metals.
- EU Regulation 10/2011: Certified overall migration limits under diverse food simulant conditions (alcohol, acid, fatty food stimulants).
- Drop & Compression Testing: Precision wall thickness distribution prevents bottom crack failure when dropped from 1.5-meter bar heights.
5. Frequently Asked Questions (FAQ) for Beverage Brand Sourcing Directors
Q1: Can your 95mm PP cups be sealed with standard automatic plastic cup sealing machines?
Yes. Our 95mm PP cups are precision-engineered with flat, reinforced upper rims specifically calibrated for automatic heat-sealing film equipment. They weld seamlessly with standard PP and easy-peel sealing films at operating temperatures between 160°C and 180°C.
Q2: What is the minimum order quantity (MOQ) for custom logo printed plastic cups?
For custom printed PET or PP cups, our standard MOQ is 10,000 pieces per size. For plain unprinted cups, we support trial orders starting from 5,000 pieces.
Q3: Which lid styles are available for your PET and PP cup lines?
We manufacture matching flat straw-slot lids, cross-cut lids, crystal dome lids with holes (for whipped cream), strawless sipping lids (sip lids), and PP flip-top injection bear lids.
Q4: Can PET cups hold hot drinks like hot coffee or freshly brewed tea?
No. PET plastic has a maximum thermal resistance threshold of approximately 60°C (140°F). For hot beverages, you must select our heat-resistant PP cups (up to 120°C) or our Double Wall Insulated Paper Coffee Cups.
Q5: How many cups fit in a standard 40HQ ocean shipping container?
Depending on cup capacity (12oz, 16oz, 24oz) and nesting sleeve efficiency, a 40HQ container typically accommodates between 650,000 and 1,000,000 cups, minimizing ocean freight costs per unit.
Q6: How long does production and shipping take?
Standard production lead time for custom printed orders is 12–18 calendar days after final artwork sign-off. Shipping times vary by destination port (e.g., 14–18 days to US West Coast, 25–30 days to European main ports).
Q7: How can I request cup samples and custom dieline templates?
