Paper wood

Abstract

The invention discloses paper wood. The paper wood is prepared from the following components in percentage by weight: 20-40% of dried leaves, 10-30% of fresh leaves, 5-20% of leaf skin, and 10-50% ofleaf fibers, wherein the dried leaves are one or more of dried magnolia tree leaves, dried bodhi tree leave, dried loquat tree leaves and dried pine tree leaves; the fresh leaves are one or more of fresh magnolia tree leaves, fresh bodhi tree leaves, fresh loquat tree leaves and fresh pine tree leaves; the leaf skin is one or more of magnolia tree leaf skin, bodhi tree leaf skin, bock greenbrier rhizome leaf skin, sycamore tree leaf skin and white poplar leaf skin. A product manufactured by the paper wood can be completely degraded within one month in a natural environment, and is harmless onenvironment. The paper wood further has high temperature resistance, can be kept stable for a long time at a temperature of 140 DEG C, is not carbonized, can replace plastic food package, and is beneficial for eliminating white pollution.

Description

technical field [0001] The invention relates to a paper material. Background technique [0002] With the extensive use of smart phones, the food delivery industry has entered a prosperous era. People only need to open the food delivery software in their mobile phones to order food delivery of various delicacies. The prosperity of the food delivery industry has also brought a huge challenge to the environment. At present, most of the lunch boxes used in the food delivery industry are made of plastic, which are almost non-degradable and harmful to the environment. There are also some degradable plastic lunch boxes on the market. The degradation cycle of these degradable plastics is still long, generally several years, ten years or even decades, and many toxic substances will be produced during the degradation process; in order to solve the problem of degradation, a small number of takeaway lunch boxes use tin foil or They are made of hard paper, but none of them can replace p...

Problems solved by technology

The prosperity of the food delivery industry has also brought a huge challenge to the environment. At present, most of the lunch boxes used in the food delivery industry are made of plastic, which are almost non-degradable and harmful to the environment. There are also some degradable plastic lunch boxes on the market. The degradation cycle of these degradable plastics is still long, generally several years, ten years or even decades, and many toxic substances will be produced during the degradation process; in order to solve the problem of degradation, a small number of takeaway lunch boxes use tin foil or They are made of hard paper, but none of them can replace plastic lunch boxes for the following reasons:

[0003] First, tin foil is expensive and easy to break, and tin foil has good thermal conductivity. When holding food with high temperature, the temperature of tin foil is equivalent to the temperature of food, which may easily cause burns to delivery personnel and users;

[0004] Second, the paper lunch box has poor heat resistance. When the temperature of the food is above 75 degrees Celsius, the paper lunch box will carbonize and turn yellow, and the carbonized lunch box will pollute the food and endanger the health of diners.
