PP vs PET Cups: Which Custom Cup Material Should You Choose?

If you sell cold beverages and you're comparing custom cup materials, the decision usually comes down to two options: PP (polypropylene) and PET (polyethylene terephthalate). Both are food-safe, printable, and built for cold drinks — but they solve different problems.

The short answer

Choose PP if cost and durability matter most — it's the cheaper, more flexible, crack-resistant option used by the majority of bubble tea shops, smoothie bars, and quick-service restaurants. Choose PET if visual presentation is the priority — its glass-like clarity shows off layered drinks, cocktails, and specialty beverages where color is part of the sell.

Cost difference

At 1,000 units with a 3-color print, PP typically runs 15-20% cheaper than PET. That gap narrows at higher volumes but rarely disappears — PP resin is simply less expensive to produce than PET resin.

Clarity and shelf appeal

PET is virtually crystal clear, closer to glass than any other disposable plastic. PP has a light frosted, translucent look. If your drink's color is part of the brand experience — think layered lattes, colorful boba, or craft cocktails — PET makes that visible in a way PP can't.

Durability

PP flexes without cracking, which matters for crushed ice drinks, squeezing, and rough handling in transit. PET is more rigid and can crack under stress or if dropped on a hard edge — a real consideration for delivery-heavy operations.

• Pick PP for bubble tea, smoothies, frozen drinks, and cost-sensitive high-volume operations.
• Pick PET for cocktails, specialty coffee, and any drink where visual presentation drives sales.
• Both support 1-3 spot color screen printing and a 250-unit minimum order.
