All About PLA and CPLA - Vegware

Understanding Compostable Bioplastics PLA and CPLA from Plant Starches

At Vegware, we manufacture our disposable catering products using a variety of plant-based materials. We utilize paper, cardboard, and pulp, but the key difference is that we do not use conventional plastics.

Nobody wants leaks from their cups, and our customers desire clear windows, which is why we use compostable bioplastics derived from plant sources.

Our compostable lunchware includes cold PLA cups, portion containers, PLA coatings in our hot cups, and CPLA lids and cutlery.

What is PLA?

PLA is a compostable bioplastic made from plant sugars. PLA stands for polylactic acid. It can be made from any sugar source, such as corn starch, cassava, sugar cane, or sugar beet. NatureWorks is the world’s largest producer of PLA and a key partner of Vegware. Currently, industrial corn is the primary crop source, but NatureWorks is actively working to diversify raw materials.

NatureWorks refers to its PLA under the Ingeo brand and provides comprehensive online information on how it is made and end-of-life options.

How PLA is Made

Corn plants are ground to extract starch in the form of glucose. This glucose undergoes fermentation to produce lactic acid. Subsequently, a chemical process transforms lactic acid into a polymer, which can be turned into pellets, known in the industry as resin.

Like conventional plastic resins, PLA pellets can be used in various ways: extruded into sheets or films, injection molded, poured into molds, or spun into fibers. PLA has a wide range of applications, but at Vegware, we utilize it for:

• Moisture-resistant coatings in paper cups and bowls
• Clear cold cups, salad containers, sauce pots
• Lids for various products
• Clear windows in sandwich wedges, salad boxes, and catering trays

CPLA: Crystallized PLA for Higher Heat Uses

PLA has a low melting point, making it better suited for cold applications, up to around 40ºC (105ºF). Where more heat resistance is needed, such as in cutlery and coffee cup lids, we use a crystallized form. This involves adding chalk to PLA to act as a catalyst and then rapidly heating and cooling the PLA resin during production. The result is a product stable at temperatures up to 90ºC (194ºF). Vegware’s CPLA products are suitable for industrial/commercial composting.

CPLA is crystallized PLA, suitable for hotter applications like coffee lids or cutlery.

Corn for Food, Feed, and Industrial Uses

The industrial corn used to make NatureWorks’ Ingeo PLA is not food-grade, meaning it does not compete with food for human consumption. The entire plant is harvested, and every part is utilized. Plant proteins are used to create animal feed, while the starch has many industrial applications, including airbags, corrugated cardboard, recycled paper, pharmaceuticals, condoms, and the production of PLA.

PLA: What Waste Stream?

Vegware’s compostable disposable catering products can biodegrade in less than 12 weeks in commercial composting, providing the perfect balance of microbes, moisture, and heat.

Where there is no access to industrial composting, used Vegware should be placed in general waste. Vegware’s take-out packaging is made from plants, not plastic, utilizing renewable, lower-carbon or recycled materials, and these sustainability benefits still apply regardless of what happens after their use.

• Used Vegware should NOT be placed in standard recycling bins that collect paper and plastics, as these materials go to a different type of sorting facility. Another reason is that food waste negatively affects the quality of mechanical recycling; the same applies to any used food service disposables, even those made from "recyclable" plastics.
• General waste goes to incineration or landfill.
• In landfills, studies have shown that compostable packaging is inert and does not emit methane. PLA does not decompose in a landfill, but neither do other materials.
• Please do not litter: compostable packaging is not expected to break down when discarded in the natural environment and is not a solution to marine pollution.
• Home composting conditions vary depending on the owner's skill, so we make no claims about this, but successful trials have been conducted using hot composting bins.

What is the Difference Between Ingredients in CPLA and PLA Dinnerware?

The difference between the ingredients of CPLA and PLA dinnerware products is significant. With rising environmental awareness, the demand for biodegradable dinnerware is increasing. Compared to traditional plastic dinnerware, CPLA and PLA products have become more popular in the market due to their biodegradable and compostable properties. So, what is the difference between the ingredients of CPLA and PLA dinnerware? Let’s delve into a scientific overview.

First, let’s review the ingredients of CPLA. The full name of CPLA is Crystallized Polylactic Acid. It is a material mixed with polylactic acid (PLA) and reinforcing agents (such as mineral fillers). PLA, as the main ingredient, is more common among eco-friendly materials. It is produced through the fermentation of renewable plant starches such as corn starch or sugar cane. PLA dinnerware is made from pure PLA material, which is naturally degradable and very eco-friendly. Since the source of PLA is primarily plant-based raw materials, it does not cause environmental pollution when decomposed.

Second, let's look at the degradability of CPLA and PLA dinnerware ingredients. Both CPLA and PLA dinnerware are biodegradable materials that can decompose in suitable environments. However, due to certain reinforcing agents added to CPLA to enhance its crystallinity, CPLA dinnerware takes longer to degrade. Conversely, PLA dinnerware degrades relatively quickly, typically taking several months to a few years to decompose completely.

Third, let’s discuss the difference between CPLA and PLA dinnerware in terms of compostability. Due to the natural degradability of PLA materials, it can be composted under appropriate composting conditions and eventually break down into fertilizers and soil amendments, providing more nutrients to the environment. Because of its high crystallization, CPLA dinnerware degrades more slowly, which can prolong the composting process.

Fourth, we need to consider the environmental performance of CPLA and PLA dinnerware. Whether it’s CPLA or PLA dinnerware, both can effectively replace traditional plastic dinnerware, thereby reducing environmental pollution. Thanks to their degradable properties, using CPLA and PLA dinnerware can diminish plastic waste generation and reduce the harm to the natural environment. Additionally, since CPLA and PLA are made from renewable plants, their production process is relatively eco-friendly.

Finally, it’s important to acknowledge differences in the use of CPLA and PLA dinnerware. CPLA dinnerware is relatively resistant to high temperatures and oil. This is due to the addition of some reinforcing agents during the production of CPLA dinnerware, increasing the material's crystallinity. When using PLA dinnerware, care should be taken to avoid the effects of high temperatures, grease, and other factors. Furthermore, as CPLA dinnerware is produced by hot pressing at high temperatures, it maintains a relatively stable shape and does not deform easily. PLA dinnerware typically employs injection molding technology, which can create various shapes.

In summary, the differences between CPLA and PLA dinnerware ingredients are notable. CPLA dinnerware consists of a highly crystalline material mixed with polylactic acid and reinforcing agents. It offers good resistance to high temperatures and oils. On the other hand, PLA dinnerware is made from pure PLA material, which decomposes swiftly and is easy to compost. However, care must be taken to avoid using it under high temperature and greasy conditions. Both CPLA and PLA dinnerware are eco-friendly biodegradable and compostable products, effectively reducing the environmental pollution caused by plastic waste.

We hope this scientific introduction helps you better understand the differences between the ingredients of CPLA and PLA dinnerware products. Choose the eco-friendly dinnerware MVI ECOPACK and do your part to protect the environment.
