CPLA for sustainable packaging | Green Box

PLA and CPLA – Sustainability Rarely Comes Alone

You might be wondering what exactly the difference between PLA and CPLA is. PLA stands for polylactides, a biodegradable plastic made from renewable raw materials such as corn starch. It is known for its use in the production of compostable plastic products.

CPLA, on the other hand, is a modified form of PLA. CPLA stands for crystalline polylactide and is a version of PLA that offers more heat resistance. Through a crystallization process, the material is reinforced, making it suitable for applications where higher temperatures are involved, such as cutlery or coffee cups – so every hot beverage can be enjoyed comfortably and environmentally friendly with the heat-resistant CPLA!

The main difference lies in the temperature resistance. CPLA products are better suited for hot contents, while PLA is more used for cooler or moderate conditions. Both are biodegradable, making them a more environmentally friendly alternative to traditional plastics.

CPLA - the bioplastic for sustainable packaging

By using this bioplastic, you are on the sustainable side. Especially the reduction of petroleum-based products is a clear advantage.

CPLA products are biodegradable and can be industrially composted. Have the advantages of the CPLA material convinced you?

Then discover our comprehensive range and find the right lid for your cup, which is not only environmentally friendly but also functional!

Especially when it comes to packaging in the catering sector, environmentally friendly materials should represent a sensible alternative to plastic. Petroleum-based plastic products have long since become absolutely unnecessary – even without an EU ban. From palm leaves to cardboard to stable products made from bagasse, Wisefood offers consumers and catering operators a wide range of sustainable crockery, cutlery, cups and packaging. Again and again one hears about CPLA in connection with sustainability. But hardly anyone knows what actually lies behind this term.

PLA as the basis for CPLA

To understand what CPLA is, you first have to know what PLA – the basis of CPLA – is all about. PLA, the abbreviation for polylactide, is a synthetic polymer that consists of renewable raw materials and is therefore considered a sustainable bioplastic. PLA is also biodegradable. PLA is obtained from starchy plants such as corn or beets. The starch is extracted from these plants and converted into lactic acid by microorganisms such as lactic acid bacteria. Thanks to its stable structure, it can be used in many ways, for example as an inner coating for disposable coffee cups, packaging material, cutlery or straws.

But there are now alternatives for cups and bowls with PLA inner coatings, such as the stable paper cups with water-based inner coating from Wisefood.

PLA becomes CPLA

For the production of CPLA, up to 30% talcum powder is added to the lactic acids, which allows the lactic acids to crystallize. This creates a non-transparent, but quite hard and stable granulate - the so-called crystallized polylactic acid - CPLA for short.

This is far more heat-resistant than its predecessor PLA and even tolerates temperatures of up to around 85°C, which is why it is recommended as packaging material for hot drinks and food. In addition, it is just as compostable as the clear PLA. It therefore has a number of advantages and is therefore quite versatile in the to-go area and event catering - just like PLA.

But: CPLA cutlery is considered a typical disposable product and is therefore also affected by the plastic ban. CPLA packaging, on the other hand, is regarded as a transport container and may continue to be used.

Wisefood turns alternatives into superlatives

The word "alternative" always sounds a bit like a substitute and second choice. But when it comes to environmental protection, climate friendliness and sustainability, Wisefood is no longer just about alternatives. Rather, it is important to us that sustainable and environmentally friendly living and working become a matter of course. We therefore see the topic of sustainability and our products made from bagasse and other renewable raw materials not just as a mere alternative to the conventional overexploitation of our nature.

And that's why we don't make any compromises when it comes to the sustainable production of disposable packaging and disposable tableware. From cultivation to the manufacturing process to environmentally friendly disposal, we see ourselves as responsible. Because there is no alternative for our planet! With our menu boxes made from bagasse and other bagasse products, we also promote the organic cultivation of renewable raw materials.
