In recent years, green packaging materials have achieved certain research results and have been popularized and applied in China. Green environmental protection packaging materials refer to the life cycle assessment (LCA, Life Cycle Assessment) in the process of production, use and recycling, which is convenient for people to use without causing too much harm to the environment, and can degrade or degrade by itself after use. Realize recycled materials.
At present, the widely used green packaging materials in my country are mainly divided into: paper product materials, natural biological materials, degradable materials, and edible materials.
Paper materials come from natural wood resources, and have the advantages of fast degradation, easy recycling, and wide application range, making them the most common, widely used and earliest green packaging materials in China. Its typical representatives are mainly honeycomb paperboard, pulp molding and so on. However, due to the lack of forest resources in my country, excessive use will consume a large amount of wood. Therefore, with the development of technology, non-wood pulp should be actively used in the future, such as reed, straw, bagasse, etc., to replace the use of wood and cause environmental problems. irreversible damage.
After the paper packaging is used, not only will it not cause pollution and damage to the ecology, but it can be degraded into nutrients. Therefore, in today's fierce competition in packaging materials, especially due to the impact of plastic material products and foam material products, paper packaging is still There is a place, with its unique advantages.
The "paper" packaging was designed by Australian student Emily Enrica. The packaging material is made of 100% biodegradable pulp, which has good adaptability and high recyclability. It is easy to handle, easy to degrade, and reaches microwave safety and FDA. Tested for food safety. The design of the box is ergonomic, and it adopts an iron-proof design for a comfortable grip. The cover label keeps the noodles sealed and adds flavor time.
The "Pizza Tray" designed by the American Zume Pizza Company was successfully shortlisted for the DuPont Packaging Innovation Award. The packaging is composed of 100% sustainably grown sugarcane fiber, is not made from trees, is compostable and biodegradable. The tray keeps the pizza crispy and warm for a longer period of time. Maximizes oil and moisture absorption, keeping pizza warm and crispy long after it leaves the oven.
