What is CPLA Lid?
CPLA = Crystallized PLA. It's processed by applying high pressure and heat to PLA, chalk, and other biodegradable and bio-based additives. This causes the material to crystallize, resulting in a harder product that's less susceptible to heat degradation. CPLA lids are commonly used for coffee cups.
OEM & ODM Services of CPLA Lid
Diameter Customization
The diameter of the CPLA lid can be customized on demand, covering a variety of sizes to fit different containers. The small size is 2-3 inches (about 5-7.6 cm), which is suitable for small-capacity containers for single-person servings, such as high-end restaurant tasting sauce cups, mini dessert cups, and portable personal care product samples. It can be easily taken and ensure sealing and freshness. The medium size of 3.5-4.5 inches (about 8.9-11.4 cm) is the most common, mostly used for daily drink cups and regular food containers, such as medium-sized coffee cups, ordinary yogurt cups, and medium-sized soup and salad takeaway boxes in the catering takeaway industry, which can effectively prevent drinks or food from spilling. The large size of 5-6.5 inches (about 12.7-16.5 cm) is mainly used for large-capacity containers, such as large barrels of yogurt for families, large takeaway boxes, and even containers for industrial use or bulk packaging products that meet regulations, which can prevent food contamination and leakage and meet the needs of sealing and protecting products.
Thickness Options
The thickness of the CPLA lid can be customized on demand, and different thicknesses are suitable for different scenarios. The thinnest thickness is 0.01-0.03 inches (about 0.25-0.76 mm), which is common in disposable, lightweight applications. For example, the disposable coffee cup lids of coffee chains are mostly about 0.02 inches thick, and the small lids for small sauce cups and beverage stirring sticks in the fast food industry are also commonly 0.015-0.025 inches thick. The medium thickness is 0.035-0.05 inches (about 0.89-1.27 mm), which is suitable for containers that require a certain strength and durability but are not used repeatedly for a long time. For example, the lid of a medium-sized yogurt cup in an ordinary supermarket is about 0.04 inches thick, and the lid of a medium-sized soup and salad takeout box in a catering takeout is often 0.04-0.045 inches thick, which can withstand slight collisions and squeezes and ensure sealing. Thicker thickness of 0.055 - 0.08 inches (about 1.4 - 2.03 mm) is used for containers that need to be used for a long time, opened and closed repeatedly, or subjected to large external forces, such as reusable water cups and thermos cup lids, which are mostly 0.06 - 0.07 inches thick.
Color Customization
CPLA lids are highly flexible in color customization. Common customized colors are natural, black, white and transparent. Natural color shows the simplicity and nature of the material, which is suitable for environmentally friendly and original ecological products; black is suitable for products that need to be stored away from light and packaging that pursues a stable and professional sense because of its high recognition and light-shielding properties; white conveys a simple, fresh and hygienic image, and is widely used in food and high-end daily necessities packaging; transparent color allows consumers to see the product directly, enhancing its attractiveness and credibility, and is suitable for beverage cups and food storage boxes.
Closure And Sealing Mechanism
CPLA lids can be designed with snap-on or screw-in closures. Snap-on lids can be installed and removed quickly and easily, making them suitable for single-use or on-the-go applications, such as disposable coffee cups. On the other hand, screw-on lids provide a more secure seal and are often used for reusable containers or products that require long-term storage. For example, a reusable water bottle with a CPLA lid might use a screw-on mechanism to prevent leaks during shipping or storage.
In addition, the design of the sealing gasket inside the CPLA lid can also be customized. A soft rubber or silicone gasket can be added to ensure a tight seal to prevent air and liquid leakage. The thickness and shape of the gasket can be adjusted based on the specific container and application. For example, a container for carbonated beverages may require a thicker, more flexible gasket to withstand the pressure of carbonation.
Biodegradability and eco-friendliness

Process of CPLA Lid
The manufacturing of CPLA Lid begins with the extraction of raw materials, typically derived from renewable sources like corn or sugarcane. This extraction process involves harvesting the plants and processing them to obtain starch.
The extracted starch undergoes a fermentation process, where microorganisms break down the starch molecules into lactic acid. This lactic acid is then polymerized to form PLA pellets.
To create CPLA, the PLA pellets undergo a crystallization process where they are heated and cooled in a controlled manner. This process results in the formation of crystalline structures within the material, enhancing its strength and heat resistance.
The CPLA material is molded into Lid shapes using specialized machinery. The Lid are formed with precision and undergo quality checks to ensure they meet the required standards.

Rotate stock
Use older lid first to ensure they are eaten in a timely manner.
Consistently inspect
Before using lid, regularly check them for signs of degradation or damage.
Comparing CPLA VS. PLA

Choosing 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.
