Comparing CPLA vs. PLA
Comparing CPLA vs. PLA
The race to find the best alternative materials for eco-friendly restaurant supplies continues, and direct competitors for traditional plastics are becoming increasingly popular. Two of the most popular options are PLA (polylactic acid) and CPLA (crystallized polylactic acid). Both have properties that make them a better choice for the environment than traditional plastic but give them performance specifications that are just as good as traditional plastic. Here is a look at the differences between CPLA and PLA.

PLA (Polylactic Acid)
210GPLA450PLA (Polylactic Acid) is a synthetic alternative to traditional plastics. Unlike traditional plastic, PLA is made from starch derived from renewable resources like sugarcane. Although it is produced in a lab, PLA is significantly better for the environment than traditional plastic. It is biodegradable, which means that it will naturally break down over time when you dispose of it. It does not contain harmful chemicals that will leach into the soil as it breaks down, preventing long-term damage to plants and animals.
PLA is also compostable so that it can be used to create compost for enriching soil. While it is not recyclable, it can be disposed of in a way that still makes it useful. Since it is made out of natural sugarcane starch, PLA can impart nutrients to the soil, making it a viable component in growing food for the foodservice industry.
CPLA (Crystalized Polylactic Acid)
Crystallized Polylactic Acid, more commonly referred to as CPLA, is a crystallized version of PLA. Crystallizing PLA gives its fibers a much stronger structure. Because of this, CPLA is just a stronger version of PLA. It is used in applications where a less flexible material is needed, such as trays and large cutlery.
Although it is crystallized, CPLA has the same environmentally friendly properties as PLA. It is biodegradable and will break down when disposed of without hurting the environment. Home gardeners can also use it as composting material to enrich their compost and improve their gardens.
Which One to Use?
209MBZENO10Choosing between CPLA and PLA depends on the size and strength of the restaurant supplies you need. In most cases, PLA will be strong enough for your purposes. PLA is often used to create windows in windowed containers like our Kraft Paper Baguette Bag with PLA Window. It is also used to make cutlery since it has many of the properties of traditional plastic. You could very likely switch your restaurant’s traditional plastic utensils with PLA utensils without any of your customers realizing it.
In situations where you need larger restaurant supplies with a more rigid structure, CPLA is the better choice. This includes large utensils, such as tablespoons or serving spoons. CPLA can also be used to make large trays for catering services. In many cases, both options are used to make lids for eco-friendly food containers.

Understanding Bioplastics - PLA & CPLA - The Bio Group
PLA is a compostable bioplastic which is created from plant sugars. PLA is an abbreviation of polylactic acid which is made from sugars such as corn starch, sugar cane or sugar beet. Industrial corn is the primary source crop at the moment which is grown using sustainable farming practices such as:
We also use FSC paper and cardboard, REPA (made from seashells), but we never supply traditional plastics, our goal is to provide products that have the lowest possible impact on our planet.
We supply catering disposables made from a range of plant-based materials. These compostable bioplastics, made from plant starch, are the acceptable face of single-use products and are globally endorsed as the future of plastics.
Link to sontex To extract the starch, corn plants are milled and this produces glucose. Through a fermentation process, the glucose is then converted to lactic acid. Through a series of chemical processes, the lactic acid is turned into a polymer which is then used to create resin. The resin behaves just the same as traditional plastics would, which means they can be processed in lots of different ways such extruding to create sheet material or into a film, injection moulded, cast or spun. It’s extremely versatile. We stock a range of products that use PLA in them, such as: PLA has a low melt point, so it’s used mostly for cold use, up to around 40ºC. But for higher temperatures such as for cutlery or lids for hot liquid, we use a crystallised form called CPLA. The process to create CPLA involves adding chalk as a catalyst then rapidly raising and lowering the temperature during production. This makes the crystalised form of PLA stable up to 90ºC. Our PLA products biodegrade in under 12 weeks at a commercial composting site, but if you don’t have access to this then put used items in the general waste. This may seem contrary, but these products are made through low carbon processes using renewable materials so they are still a much better alternative to conventional plastics. However, you should not place these products in standard recycling bins as they can harm the quality of recycling. They are designed to be composted.
