Several packaging materials conducive to environmental protection in recent years, due to the extensive use of plastic packaging materials in product packaging, especially foam polystyrene, the impact on environmental pollution is extremely serious, directly or indirectly threatening the growth and survival of human beings, animals and plants, which has attracted the high attention and attention of relevant experts. In order to change this pollution situation, experts have stepped up research and developed some new packaging materials to replace the current plastic packaging. It is proved by practice that the effect is good. Now several new packaging materials developed abroad are introduced as follows:

1. Jujube and coconut leaves are raw materials packaging materials

this material has a structure similar to beech, and can be used to make whole materials or granular boards for packaging

2. Plant fiber/starch product materials

using long fiber plants, jute fibers and other fibers, potato starch as raw materials, the packaging materials are made by pressing molding technology. It is said that the material made of this kind of material is stronger than glass fiber, light in weight, and biodegradable. The disadvantage is that it is sensitive to water and is not suitable for moisture-proof packaging

3. Wooden packaging materials that are not easy to react

use almond shell, coconut shell, walnut shell and other raw materials, mix them with natural or synthetic resin after crushing, and then form them by pressing or injection to make imitation wood materials. After processing, this kind of material not only has good thermoplastic, but also has elegant appearance and good hand feeling. It is suitable for the packaging of high-end products

4. Bioplastics packaging material

this packaging material is made of various starch or grain as basic raw materials. Its quality is similar to that of ordinary plastics, but its processing is superior to ordinary plastics, and it can withstand various processing technologies such as molding, injection molding, extrusion molding and stretching

5、 Pulp molding packaging materials

"This is beneficial to the environment and economy.

this material can replace foamed plastic as a packing material for padding, shock resistance and shock resistance. Because it has many advantages such as convenient manufacture and use, low cost, and is suitable for machining and manufacturing various shapes, it has been widely used in packaging.

pulp molding packaging material is used for cartons of eggs, which makes the packaging more delicate and greatly reduces damage 。 Now, electronics and other products are also beginning to be adopted. The pulp molding packaging material can bear about 9 kg of packaging weight

expandable polystyrene foam protective packaging recyclable material

as early as the early 1990s, a strong environmental movement swept the United States, which awakened the environmental awareness of producers and consumers and required the recyclability of packaging materials. At that time, many relevant laws forced many producers to use recycled materials as packaging materials. Recently, the environmental protection movement has subsided, and the mandatory law has also been reduced, but some manufacturers, especially electronic companies, still feel pressure from all aspects. In addition, in order to save money, some producers are also seeking their suppliers to provide them with recyclable packaging materials. Therefore, the use of recyclable packaging materials has become a trend. Packaging producers generally deal with recyclable substances in two ways: (1) Mixed in the granular foam of waste processed plastic composites leading the revolution of bridge construction industry; (2). Buy recyclable raw materials

eps and arc can produce various thickness of foam sheet l molded foam

arcels is a polymer of 70% polystyrene and 30% polyethylene. Similar to EPS in treatment method, it is mainly used to produce expandable products. In its production process, only secondary supplier polysource can produce recyclable raw materials. The recycled raw material is finished by extrusion and granulation, and the product has been on the market for more than 6 months

in order to facilitate production and supply, packaging producers generally mix their recyclable products into used waste to form granular raw materials. Molded EPS products, especially those with high density, such as packaging products for heavy computers and electronic equipment, can be recycled up to 5% - 10%. The essence of arcel chemical process requires the cylindrical filler to be durable and corrosion resistant under high temperature and severe reaction conditions. Due to its different components, the recovery can reach 12.5%

in a word, technical factors usually limit the recovery of expandable granular raw materials to 5%-10%. In addition, the limitation on the practicality of reducible materials will further encourage packaging producers to reduce the level of recyclable materials
