Several kinds of packaging materials that are conducive to environmental protection

In recent years, due to the large number of plastic packaging materials used in product packaging, especially the impact of foamed polystyrene on environmental pollution is extremely serious, directly or indirectly threatening the growth and survival of humans and animals and plants. The relevant experts paid great attention and attention. In order to change this pollution situation, experts have stepped up research and developed some new packaging materials to replace the current plastic packaging. The practice proved that the effect is good. Several new packaging materials developed abroad are now introduced as follows:

1. date palm leaves as raw material packaging material

This material has a structure similar to that of beech wood and can be used to make monolithic materials or pellets for packaging.

2, plant fiber / starch products

Using long-fiber plants, jute fibers and other fibers, and potato starch as raw materials, press-molding molding techniques are used to make packaging materials. It is said that the materials made of such materials are stronger than glass fibers, lighter in weight, and biodegradable. The lack of water-sensitive materials is not suitable for moisture-proof packaging.

3, wood packaging materials that are not easy to react

Using almond shells, coconut shells, walnut shells, etc. as raw materials, crushed and mixed with natural or synthetic resin, and then formed by pressing or injection methods, made of wood materials. After being processed, this type of material not only has good thermoplasticity, but also has an elegant appearance and a good feel, which is suitable for high-grade products.

4, bioplastic packaging materials

This packaging material is made of various starches or grains as the basic raw material. Its quality is similar to that of ordinary plastics, but its processing is superior to ordinary plastics, it can withstand molding, injection molding, extrusion molding and drawing processing, etc. Processing technology.

5, pulp molding packaging materials

This material can replace foams as a cushion, impact and shockproof packaging material. Because it is easy to manufacture and use, the cost is low, and it is suitable for machining and manufacturing various shapes and many other advantages, it has been widely used in packaging.

Pulp moulding packaging material is used to pack eggs, making the package more compact and less damaged. Electronic and other product categories are now beginning to adopt. Pulp molded packaging materials can withstand about 9 kg of packaging weight.

As early as the early 1990s, a strong environmental movement swept through the United States. This movement has awakened the environmental awareness of producers and consumers and demanded the recyclability of packaging materials. At that time, there were many related laws that forced many producers to use recycled materials as packaging materials. Recently, the environmental protection movement has subsided and the mandatory nature of the law has also been reduced. However, some manufacturers, especially electronics companies, still feel pressure from various sources. In addition, for the sake of economy, 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 manufacturers typically process recyclables in two ways: (1) mixed in used, processed particulate foam, and (2) purchased recyclable materials.

EPS and ARCEL Molded Foam

ARCELS is a polymer of 70% polystyrene and 30% polyethylene. Similar to EPS in terms of processing, it is mainly used to produce renewable products. In its production process, only the secondary supplier Polysource can produce recyclable materials. The recycled raw materials are finished through squeezing and granulation, and the products have been on the market for more than 6 months.

In order to facilitate production and supply, packaging manufacturers generally form granular raw materials by mixing their recyclable products into old waste materials. Shaped EPS products, especially those with high density, such as packaging products for heavy-duty computers and electronic devices, have a recyclability of 5%-10%. Due to its different composition, ARCEL can recover 12.5%.

In summary, technical factors usually limit the recovery of renewable particulate materials to between 5% and 10%. In addition, the restrictions on the availability of reducible materials will further encourage packaging producers to reduce the level of recyclables.
