New 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. The new packaging materials developed abroad are 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 whole block materials or pellet boards for packaging. 2. Plant fiber/starch product materials Long fiber plants are used. Jute fiber and other fibers and potato starch are used as raw materials, and a packaging material is formed by a press forming molding technique. It is said that the materials made of such materials are stronger than glass fibers, lighter in weight, and biodegradable. The disadvantage is that such materials are sensitive to water and should not be used for moisture-proof packaging. 3. Wood packaging materials that do not react chemically are made of almond shells, coconut shells, walnut shells, etc., and are crushed and then mixed with natural or synthetic resins, and then pressed or injected to form a wood-like material. After being processed, this type of material not only has good thermoplastic properties, but also has an elegant appearance and a good feel, and is suitable for packaging in high-end products. 4. Bio-plastic packaging material This packaging material is made from various starch or sugar base materials, and its quality is similar to that of ordinary plastics. However, it is superior to ordinary plastics in processing, and can withstand various processing techniques such as molding, injection molding, extrusion molding, and drawing processing. 5. Pulp Molding Packaging Material This material can be used as a gasket, shock-proof and shock-proof packaging material instead of foam. 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 moulded packaging material is used to package eggs, making the package more compact and less damaged. Electronic and other products are now beginning to be adopted. Pulp moulded packaging materials can withstand weights of around 9 kg.
