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 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, jute fibers and other fibers, and potato starch are used as raw materials, and the molding material is formed into a packaging material by compression molding. 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 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 imitation 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. Bio-plastic packaging material 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 it is superior to ordinary plastics in processing and can withstand molding, injection molding, and extrusion molding. And stretching processing and other processing technologies. 5, pulp molded packaging material This material can replace foam, as a cushion, shock and shockproof packaging materials. 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.
