What is a PLA cup and what are its advantages?

In a context where waste reduction is a priority, the search for sustainable alternatives to plastic has transformed how food service businesses operate. The growing adoption of PLA cups in hospitality, delivery services and large events meets a real demand for solutions that limit environmental impact without sacrificing functionality.

What is a PLA cup?

A PLA cup is a container made from polylactic acid (PLA), a biopolymer that has become a benchmark in the packaging sector. Unlike conventional packaging, it does not come from petroleum, but from renewable plant-based resources.

It is obtained by fermenting plant carbohydrates, mainly from corn starch, sugar cane or sugar beet. This process turns biomass into a thermoplastic polymer, producing a biodegradable cup that offers the same functionality as plastic, with a significantly reduced carbon footprint during manufacture.

Characteristics of the PLA cup

This material stands out for combining a traditional look with a new-generation composition. Its main characteristics are:

• Crystal clarity: its appearance is identical to that of PET, giving full visibility of the product, ideal for showing off the colours of juices and smoothies.
• Rigidity and lightness: sturdy cups that do not deform easily and offer a premium user experience.
• Bio-based origin: not depending on fossil fuels, its production is cleaner and more sustainable.
• Heat sensitivity: designed exclusively for cold or room-temperature drinks, the material begins to soften above 40–45 °C.

PLA cup or traditional plastic cup: what are the differences?

At first glance, a PLA cup and a PET cup (conventional plastic) are practically identical. Their environmental and chemical behaviour, however, sets them clearly apart:

• Origin of the raw material: conventional plastic is synthesised from petroleum (a fossil, finite resource), whereas PLA comes from renewable sources such as corn or sugar beet. This reduces dependence on fossil fuels from the manufacturing stage.
• Biodegradability and persistence: a plastic cup can take up to 500 years to break down into harmful microplastics, whereas the biodegradable PLA cup disappears within a few months if properly managed.
• Carbon footprint: producing bioplastics such as PLA generates up to 60% fewer greenhouse gases compared with petroleum-based plastics.
• Waste management: PET can be mechanically recycled (plastic recycling bin), but the compostable takeaway cup is designed to return to the soil as a soil improver in industrial composting facilities (food waste bin).

Advantages of PLA cups

Choosing this type ofsustainable packaging offers direct benefits for the environment and for your business:

• A real alternative to plastic: it helps you comply with environmental regulations restricting single-use plastics of fossil origin.
• Brand image: using eco-friendly cups for your drinks improves how your business is perceived. Customers value establishments that demonstrate a genuine environmental commitment.
• Hygiene and neutrality: a food-contact-safe material that alters neither the taste nor the aroma of drinks.
• Refined look: its clarity is superior to that of other bioplastics, ideal for premium visual presentation.

Limitations and precautions for using the PLA cup

The PLA cup is a technical product that requires specific handling to retain its properties:

• Heat sensitivity: this is its main limitation. PLA has a low softening point: exposed to temperatures above 40–45 °C, the cup begins to deform. It is therefore reserved for cold or room-temperature drinks.
• Controlled storage: because of its organic origin, it must be kept in a cool, dry place, away from direct sunlight and heat sources (ovens, coffee machines), as UV light and heat accelerate its degradation.
• Specific waste management: to be truly sustainable, it must be thrown into the food waste bin. Complete decomposition occurs only under industrial composting conditions; at sea or in a standard landfill, it will be much slower.

Uses of the PLA cup

The versatility of this biodegradable cup makes it a benchmark for a variety of consumption settings.

Cold drinks in cafés and restaurants

It is the ideal container for serving iced coffees, iced teas or infused waters. Its clarity showcases the quality of the drink, with a clean, modern look that customers appreciate.

Takeaway and delivery

As a compostable takeaway cup, it is suitable for carrying fresh-pressed juices, smoothies or slushies. Rigid and resistant, it withstands transport well without losing its shape, as long as the contents are cold.

Sustainable events and trade fairs

At festivals, corporate events or trade fairs looking to limit their environmental footprint, these eco-friendly cups are a logical solution. They make it possible to replace single-use plastic in large volumes, with waste management consistent with the values of the event.

How to choose the right PLA cup

Not all bioplastics are equal. To select the sustainable packaging best suited to your business, three criteria are essential.

Capacity and design

The range of sizes is wide, from 200 ml for water in offices or at events up to 500 ml for generous smoothies or milkshakes. Choosing the exact capacity optimises the cost per serving and reduces waste, while staying consistent with your brand.

Compatibility with drinks

The main strength of the PLA cup is its clarity and rigidity for cold drinks, but it must never be used for infusions or hot coffees. Make sure your staff identify these cups as reserved for cold products, to avoid any deformation on contact with heat.

Certifications and compostability guarantees

When purchasing, check that the PLA cups carry certifications attesting to their origin and end of life. The European reference standard is EN 13432, which guarantees that the cup is suitable for industrial composting, with decomposition in 6 months at most under controlled conditions. Certified products ensure genuinely sustainable packaging for your customers, protect you in the event of inspections and reinforce the transparency of your commitment.

FAQ: the PLA cup

Is a PLA cup biodegradable?

It is designed to be compostable under industrial conditions, within the timeframes set by the EN 13432 standard. In landfill or in nature, its degradation is much slower.

Can you put a hot drink in a PLA cup?

No. PLA softens above 40–45 °C: it is reserved for cold or room-temperature drinks.

Where should you throw away a PLA cup?

In the food waste bin, where an industrial composting stream exists. It must not go in the plastic recycling bin.

What is the difference between a PLA cup and a PET cup?

They look alike, but PET comes from petroleum whereas PLA comes from renewable plant-based resources and composts under industrial conditions.

Conclusion

For your cold takeaway drinks, the PLA cup combines clarity, rigidity and a compostable end of life. Discover the Covr catalogue to choose the sizes suited to your establishment, or contact us for advice.
