eSUN PLA-coated paper cups and bowls can be customized to various specifications

Post time: Dec-23-2022

Since the advancement of the plastic ban and restriction, the use of disposable paper products has increased rapidly, however, paper products do not mean environmental protection.

Taking paper cups as an example, most of the disposable paper cups widely used in the market are paper-plastic cups. There are single-sided and double-sided coated paper cups. Most of the coatings used to make paper cups are polyethylene (PE) plastic coatings, which have high heat resistance at 80°C, which can meet the needs of most application scenarios, but it does not have natural degradation characteristics, resulting in these Non-toxic paper cups neither break down in landfills nor can they be recycled.

Since 2021, in order to achieve the double carbon target and sustainable economic and social development, disposable products based on biodegradable materials have gradually entered the field of vision of consumers. Taking polylactic acid (PLA) as an example, it is a new type of biodegradable material, suitable for various processing methods such as extrusion, injection molding, film drawing, and spinning. It is easy to process, so it can be used in food packaging, fast food lunch boxes, non-woven fabrics, industrial and civilian fabrics, agricultural fabrics, 3D printing and other fields. PLA-coated paper itself is completely biodegradable and does not contain any additives.

1. About PLA-coated paper

PLA-coated paper is a technology that combines PLA and paper. It can be used to make a variety of products, such as cold (hot) drink cups, coffee cups, soup bowls, paper plates and lunch boxes. Compared with traditional polyethylene-coated paper, PLA-coated paper can not only play the role of waterproof, oilproof, heat insulation, etc., but also has the characteristics of being non-toxic and completely biodegradable.

 

2. Features of eSUN PLA-coated paper

100% bio-based, according to EN13432 and ASTM D6400. In the composting environment, completely decomposed into carbon dioxide and water, environmentally friendly, non-toxic, low-carbon release. Non-toxic and harmless to the human body, biology and environment. The use of PLA-coated paper to make cups and boxes will not emit harmful odor and any harmful substances harmful to human health. It is safer than polyethylene-coated food utensils. Comply with FDA and EU food contact regulations.

Paper Cup GB/T27590-2011 National Standard

 

① No pattern can be printed within 15mm of the cup mouth.

 

② Fluorescent brighteners cannot be added artificially.

 

2. Five Features of PLA Paper Cups

① Material environmental protection: Polylactic acid (PLA) coated paper replaces polyethylene (PE) coated paper. PLA is a biodegradable material, which is made by fermentation of agricultural crops such as corn. The production process of PLA is pollution-free, biodegradable and recyclable in nature, making it an ideal green polymer material. It is in line with the global and national environmental policy of plastic restriction and ban.

 

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

 

 

③ Material resistance to high and low temperatures: Polylactic acid (PLA) coated paper has good resistance to high and low temperatures, and will not leak or deform when made into cold and hot liquid containers. It has good strength and heat-sealability, and meets the requirements of coated paper cups.

 

 

④ Uniform coating layer: The polylactic acid coating layer is uniform, flat and smooth, and has a good feel. It has excellent quality such as increased adhesion and gloss.

 

 

⑤ Water and oil resistance: Polylactic acid-coated paper has the characteristics of traditional polyethylene (PE) coated paper to block water and oil.
