The "plastic restriction order" in the civil aviation field has been upgraded, and eSUN biomaterials continue to contribute to the green development of the civil aviation industry.

The Work Plan for Plastic Pollution Control in the Civil Aviation Industry (2021-2025) issued by the Civil Aviation Administration clearly states that from 2022, disposable non degradable plastic bags, disposable non degradable plastic straws, mixing rods, meal/cup sets and packaging bags are prohibited from being provided in relevant areas of airports with an annual passenger throughput of more than 2 million (including) passengers and domestic passenger flights, and the implementation scope will be further expanded to national airports and international passenger flights from 2023.

 

Since 2021, some civil aviation enterprises have started the upgrading of disposable plastic products in the aviation industry. In December 2021, eSUN won the bid in two projects related to biodegradable plastics of China Southern Airlines, helping the green development of the civil aviation industry. In 2023, with the further expansion and upgrading of the "plastic restriction order", the application of biomaterials in the civil aviation industry will continue to increase and deepen.

 

eSUN has worked hard in the biomaterial industry for many years, and can provide customers with biodegradable raw materials, modified materials and products with stable and excellent performance, such as degradable cups, lids, lunch boxes, degradable film bag products, degradable knives, forks, spoons, straws and other products.

 

1.Biodegradable Raw Materials and Modifiers

 

eSUN has biodegradable film materials, film blowing materials, straw materials, injection plastics and sheet materials with stable and excellent performance, which can be used in various occasions. At the same time, the PLA fiber easily produced by eSUN can also be used to make blankets, headrests, pillow pieces, quilts, etc. required by the civil aviation industry.

 

2.Biodegradable Coating Material and Its Application

 

Features of eSUN biodegradable coated paper cup:：

① Environmental protection of materials

eSUN biodegradable coated paper cup uses PLA coated paper instead of traditional PE coated paper. Poly (lactic acid) is a biodegradable material, which is pollution-free and biodegradable in the production process. The material is environmentally friendly and healthy, meeting the requirements of global plastic restriction.

 

② Material safety

The safety of PLA is very good. Polyethylene (PE) coated paper may be oxidized to carbonyl compounds in the process of hot melting or coating on the cup paper, and the cup may volatilize odor when poured into hot water. Polylactic acid coated paper has no peculiar smell, and has certain bacteriostasis and ultraviolet resistance.

 

③ High and low temperature resistance of materials

Poly (lactic acid) (PLA) coated paper has good high and low temperature resistance. It does not leak or deform when making cold and hot liquid containers. It has good strength and heat sealing, meeting the requirements of coated paper cups.

 

④ Uniform cup wall

The polylactic acid coating layer is uniform, smooth and smooth, and has a good feel. Have strong adhesion, glossiness and other excellent quality.

 

⑤ Water and oil blocking

Polylactic acid coated paper has the characteristics of water and oil resistance of traditional polyethylene (PE) coated paper.

 

3.Biodegradable Blown Film Material and Its Application

 

eSUN biodegradable blow film material is easy to blow film, has good processing performance, can be completely biodegradable, meets EN13432, ASTM D6400 standards, and meets food safety and health standards. The film made of this material has good tear resistance, good air permeability, easy printing, and good heat sealing performance. The heat sealing strength can reach more than 10 MPa, and can meet the different needs of customers. The stiffness and transparency of the film can be adjusted according to requirements.

 

In the civil aviation industry, it can be used to make degradable packaging bags, garbage bags and other film products.

 

4.Biodegradable Straw Material and Its Application

 

eSUN Biodegradable Straw Features:

① 100% bioplastics from corn and other plant starch;

② Comply with European EN13432 and American ASTM D6400 standards;

③ The material is safe and healthy, and can be directly contacted with food for hot and cold drinks;

④ The material is environmentally friendly, and the compost is 100% biodegradable after the use of polylactic acid straw, without environmental pollution.

 

*We can provide customized production services for straws according to user needs.

 

5.Biodegradable Injection Plastics and Their Applications

 

Features of biodegradable plastic injection products:

 

① Non petroleum based biological materials, low carbon and environmental protection, renewable resources, saving oil resources;

② Good mechanical property, high rigidity and impact resistance;

③ Good processing performance, wide process range, easy to shape, continuous nozzle, fast cooling and shaping, easy to demould;

④ Good surface gloss;

⑤ Low shrinkage and good dimensional stability;

⑥ It is resistant to various solvents and easy to color print.

 

Biodegradable plastic injection can be widely used in the civil aviation industry to produce degradable knives, forks, spoons, stirring rods, disposable degradable plastic cups and other tableware.

 

6.Biodegradable Tablet Materials and Applications

 

Features of biodegradable sheet materials:

A. 100% biological base, conforming to EN13432 and ASTM D6400 standards;

B. High melt strength and good thermal stability;

C. Ordinary sheet plastic suction equipment can be used for processing, and the processing efficiency is high. Transparent sheet and opaque sheet can be made.

 

Transparent sheets have high transparency, close to traditional PET sheets, and can be made into various blister products. It is convenient to observe the products in the packaging box, beautiful and generous. It can be made into disposable vegetables, salad boxes, fresh fish trays, etc., safe and hygienic. In addition, it can also be made into disposable transparent cups, juice cups, etc.

 

7.Biodegradable Fiber and Its Application

 

ESUN's own polylactic acid fiber can be made into polylactic acid spunbonded non-woven fabric, which is widely used in the civil aviation industry and can be used as the head piece of aircraft cabin seats, with the following characteristics:

1. The product is thin and light.

2. Moderate softness and good comfort.

3. It is porous, breathable and dry.

4. It is formed by hot bonding, free from other chemical components, non-toxic, odor free and irritating.

 

At the same time, polylactic acid fiber can also be used to produce whole corn fiber health quilts. If customers have needs, eSUN Eason also supports product customization.
