PE coated paper and PLA coated paper are two popular types of eco-friendly food packaging materials. Both of these materials have their own unique features and benefits. In this article, we will compare the two and analyze which one is better.
1. PE Coated Paper:
PE stands for polyethylene, which is a type of plastic. PE coated paper is a paper that has been coated with a thin layer of polyethylene. This coating makes the paper waterproof and grease-resistant. PE coated paper is widely used in the food packaging industry, as it is an affordable and versatile option.
Benefits of PE Coated Paper:
Cost-effective: PE coated paper is an affordable option compared to other types of food packaging materials.
Waterproof: The polyethylene coating makes the paper waterproof, making it ideal for packaging foods that contain liquids, such as disposable paper cups.
Grease-resistant: The coating also makes the paper resistant to oils, making it ideal for packaging greasy foods such as fast food, such as KFC buckets.
Wide range of uses: PE coated paper can be used for all kinds of food, including hot and cold food, cold drink, hot drink paper cups, etc.
Drawbacks of PE Coated Paper:
Not biodegradable: The polyethylene coating is not biodegradable, which means it can take a long time to decompose.
Not compostable: PE coated paper cannot be composted, which means it cannot be used as a soil amendment.
Plastic content: PE coated paper contains a thin layer of plastic, which can be harmful to the environment.
2. PLA Coated Paper:
PLA stands for polylactic acid, which is a type of bioplastic made from renewable resources like corn starch or sugarcane. PLA coated paper is a paper that has been coated with a thin layer of PLA. This coating makes the paper biodegradable and compostable, which is ideal for eco-friendly food packaging.
Benefits of PLA Coated Paper:
Biodegradable: The PLA coating is biodegradable, which means it can decompose into natural materials.
Compostable: PLA coated paper can be composted, which means it can be used as a soil amendment.
Eco-friendly: PLA coated paper is made from renewable resources, which makes it an eco-friendly option.
Safe: PLA coated paper is safe for food contact, as it does not contain any harmful chemicals.
Drawbacks of PLA Coated Paper:
Higher cost: Compared with other traditional food packaging materials, such as polyethylene coated paper, PLA coated paper has a higher cost. This is due to the limitations of the raw materials, production process, and production technology of PLA coated paper. Due to its high cost, it may increase the cost of product packaging.
The scope of application is limited: The main component of PLA coated paper is bioplastics. Compared with traditional polyethylene coated paper, PLA coated paper is not as good as polyethylene coated paper in heat resistance, water resistance and oil resistance. Therefore, its scope of use is limited.
Poor thermal stability: The thermal stability of PLA coated paper is not as good as that of traditional polyethylene coated paper. At high temperature, PLA coated paper is easily deformed or deteriorated, which may have a certain impact on the packaged food.
3. Which one is better?
The answer to this question depends on the specific needs of the user. If cost is a major factor, then PE coated paper is the better option. It is affordable and widely available, making it a popular choice in the food packaging industry. However, if eco-friendliness is a priority, then PLA coated paper is the better option. It is made from renewable resources, biodegradable, and compostable. It is also safe for food contact, making it a popular choice for eco-conscious consumers.
In conclusion, both PE coated paper and PLA coated paper have their own unique features and benefits. When choosing between the two, it is important to consider factors such as cost, eco-friendliness, and suitability for specific food products.
