PP vs PET Cups: Quick Comparison Table

Material Composition

• What is PP?

It is a food-grade thermoplastic and the most commonly used high-temperature resistant raw material for disposable food packaging. It is made by polymerizing petroleum after refining.

• What is PET ?

It is an unsaturated polyester material composed of elements such as carbon, hydrogen, and oxygen, and is widely used in packaging, electronics, medical and health, construction, and automotive industries.

Temperature Resistance

• PP plastic cups have a melting point of 160-170 ℃, and conventional models can withstand high temperatures of 100-130 ℃ for a long time. They are not easily deformed at high temperatures and do not release harmful substances. Even in temperatures as low as -20℃, they maintain excellent toughness and are not prone to cracking when used in alternating hot and cold environments. The universal feature of hot and cold is suitable for various food packaging. You only need to stock PP drinkingcups, greatly reducing inventory pressure while effectively increasing order coverage.
• PET plastic cups have a safe temperature tolerance range of 0℃ to 60℃. In high temperature environments, it may also accelerate the precipitation of harmful substances. Therefore, they are only suitable for holding room temperature beverages and various cold drinks. PET drinking cups are the preferred choice for premium cold drink packaging, complementing the high-temperature resistant PP cups to complete the product portfolio.At the same time, it covers the demand for cold and hot beverages in all scenarios, expanding your product portfolio to capture more business opportunities.

Transparency

• Frosted PP cups feature a semi-translucent, milky-white appearance with a matte finish.While not as transparent as PET, they support in-mold bonding technology, making them suitable for high-end beverage brands that prioritize high-quality branding and packaging.
• Clear PET cups offer exceptional clarity with a light transmittance of over 90%, providing a crystal-clear, haze-free appearance that beautifully showcases the color and layers of beverages. Clear plastic cupis currently the preferred choice for bubble tea shops, coffee shops and other cold beverage businesses.

Impact Resistance

• Disposable PP plastic cups offer excellent toughness and flexibility, and have excellent drop and pressure resistance. They can withstand heavy stacking without easily cracking or deforming, making them ideal for long-distance food delivery.
• Disposable PET plastic cups are rigid yet slightly brittle, and their bodies don’t easily soften or collapse. They won’t deform even after being held for extended periods, making them more suitable for store displays and short-distance takeaway of cold drinks.

Cost Comparison

The purchase price per ton of native PET raw materials is slightly lower than that of PP, and under the premise of completely consistent capacity and wall thickness, the single cost of conventional thin PET beverage cups is lower. Premium PP cups with thicker walls, frosted finishes, or in-mold labeling (IML) offer greater perceived value, and leave you with more ample profit margins. Customized printed PET cups can produce highly recognizable brand packaging at a lower cost, with outstanding cost-effectiveness, and can help you accelerate capital turnover.
