What is a PLA Cup?
If you’ve ever wondered what is a PLA cup, you’re not alone. PLA stands for Polylactic Acid, a bioplastic made from renewable plant-based resources such as corn starch, sugarcane, or cassava. Unlike petroleum-based plastics, PLA is derived from natural materials, making it a more sustainable choice for disposable food and beverage packaging.
PLA cups are designed to look and feel like traditional plastic cups but are far more environmentally friendly. They are compostable, meaning they can break down into carbon dioxide, water, and organic matter in a commercial composting facility—typically within 180 days under the right conditions. This is different from biodegradable products, which may take years to break down and often leave behind microplastics or toxic residues. Compostable PLA products, by contrast, leave no harmful traces.
Another key difference between PLA cups and traditional plastic cups is their source and end-of-life behavior. Standard plastic cups are made from fossil fuels and can persist in the environment for hundreds of years. In contrast, PLA cups are made from rapidly renewable resources and are designed to return to the earth much more quickly and cleanly.
So, what is a PLA cup? It’s a practical, eco-conscious alternative to conventional plastic that helps reduce your environmental footprint—without sacrificing performance or appearance. No wonder PLA cups are becoming the go-to choice for sustainable foodservice businesses around the world.
Are PLA Cups Safe for Food and Beverages?
Yes, PLA cups are safe—as long as they’re used as intended. Made from food-grade, plant-based materials like corn starch, PLA (polylactic acid) is non-toxic, BPA-free, and certified for safe food contact under standards like FDA, BPI, and EN13432.
While they look like plastic, PLA cups are compostable and derived from renewable resources. They’re ideal for cold beverages under 50°C, such as iced coffee, smoothies, or soda. However, they’re not suitable for hot drinks, as PLA softens at higher temperatures.
So, can you drink out of a PLA cup? Absolutely—just make sure it’s a cold beverage.

Can You Drink Hot Beverages from a PLA Cup?
A common question customers ask is: can you drink out of a PLA cup when it comes to hot beverages? The short answer is no.
PLA (Polylactic Acid) is a heat-sensitive bioplastic, which means it starts to soften and lose its shape when exposed to temperatures above 50°C (122°F). If you pour a hot drink like coffee or tea into a PLA cup, the material may warp, deform, or even leak—making it unsuitable and unsafe for serving hot liquids.
This heat limitation is a key difference between PLA cups and other eco-friendly alternatives. While a compostable party cup made from PLA is ideal for cold drinks, it’s not designed for hot use. Instead, we recommend using compostable paper cups with a PLA lining, which are engineered to handle higher temperatures while remaining compostable.
So, can you drink out of a PLA cup? Absolutely—for cold beverages like iced coffee, smoothies, juices, and soft drinks. Whether you’re hosting a green event or stocking an eco-conscious café, a compostable party cup is a smart, sustainable choice for cold drinks—just don’t use it for hot ones.

Storage, Shelf Life & End-of-Life Facts
To get the most out of your PLA cups, it’s important to store them properly and understand their life cycle. PLA cups should be kept in a cool, dry place, away from direct sunlight and heat sources. When stored under these conditions, they maintain their integrity and quality for over 12 months from the date of delivery.
One of the biggest advantages of PLA cups is their eco-friendly end-of-life process. Unlike traditional plastic, which can take hundreds of years to break down, PLA cups fully compost within 180 days in a commercial composting facility. During this process, they break down into non-toxic elements—carbon dioxide, water, and organic matter—without leaving microplastics behind.
It’s also worth noting the difference between compostable and biodegradable. While both terms refer to materials that break down naturally, compostable products like PLA cups do so within a defined time frame and leave no harmful residues. In contrast, biodegradable items may degrade eventually, but the timeline and environmental impact are often uncertain.
By choosing PLA cups, you’re not only using a safe and high-quality product—you’re also supporting a circular economy that helps reduce waste and pollution from single-use plastics.
