eSUN launches the biodegradable PLA coating cup

Disposable paper cup is widely used in daily life. Compared to disposable plastic cup, the disposable paper cup is traditionally seen as more environmentally friendly and less dangerous to human body.

But in fact, do you really have clear perception about paper cup?

About disposable paper cup

It is reported that there are three main types of disposable paper cup on the market at present. One is made of white cardboard, which is mainly used to hold dry things and cannot hold water or oil. Second, waxed paper cup are more waterproof and thicker, but the wax, which itself contains cancer-causing polycyclic aromatic hydrocarbons, melts once the water in the cup rises above 40 degrees. The third is now widely used plastic paper cup, which has a layer of paper outside and a layer of film inside. If the material used is inferior or the processing technology is not good, harmful substances will be produced.

At present, most of the film used for making paper cups on the market are polyethylene (PE) plastic film, which has high heat-resistance, up to 80℃ ,but  no capacity of degrading naturally

In 2021, the vigorous promotion of plastic ban greatly affected people’s daily life.  Under natural conditions, it will take more than 100 years to degrade PE used in paper plastic cup, which cannot meet the needs of the current environment and market. Consequently, the polylactic acid (PLA) coated paper cups emerged.

        About PLA coated paper

Polylactic acid (PLA) is a new biodegradable material, suitable for extrusion, injection molding, film drawing, spinning and other processing methods. It is easy to process, so it can be used in food packaging, fast food lunch boxes, non-woven fabrics, industrial and civil fabrics, agricultural fabrics, 3D printing and other fields. PLA coated paper itself is completely biodegradable without any additives, so it has advantages and characteristics in making paper cups.

Now, I will introduce the PLA coated paper cup launched by eSUN in detail.

Polylactic acid (PLA) Coated Paper Cup

         一、Implementation Standards

Paper Cup GB/T27590-2011 National Standard

         二、Five Characteristics of PLA Paper Cups

            1. Eco-friendly material: Polylactic acid (PLA) coated paper replaces polyethylene (PE) coated paper. PLA is a biodegradable material made by fermenting crops such as corn. Poly (lactic acid) is an ideal green polymer material because it is produced without pollution and can be biodegraded and recycled in nature. This material conforms to the global, national plastic limit, plastic ban environmental protection policy.

           2. Safe material: Polylactic acid has good safety property. Polyethylene (PE) coated paper may be oxidized into carbonyl compounds during the process of melting or applying to the cup paper, and the cup may emit peculiar smell when poured into hot water. While Polylactic acid coated paper has no peculiar smell, and has certain antibacterial and anti-ultraviolet properties.

         3. Resistance to high and low temperatures: Polylactic acid (PLA) coated paper has good resistance to high and low temperatures, so it will not leak or deform when made into cold and hot liquid containers. It has good strength and heat-sealing property, meeting the use requirements of coated paper cups.

        4. Uniform coating layer: The polylactic acid coating layer is uniform, flat and smooth, and has a high-quality feel. It has excellent quality such as strong adhesion and glossiness.

        5. Resistance to water and oil : PLA coated paper has the same characteristics of resistance to water and oil as traditional PE coated paper
