Technology for processing plant leaves

Abstract

The invention relates to a technology for processing plant leaves, comprising the following technological steps: selecting leaves and removing dirt, namely, selecting the leaves with a certain area and no toxicity and removing the dirt after picking; drying and smoothing, namely, putting the plant leaves in a dry clip and carrying out drying and smoothing processing; and compounding a film, namely, bonding the film and the surfaces of the plant leaves. The step of picking the leaves and removing the dirt and the step of compounding the film also can have one or more following technological steps: surface wax removal, vein planishing, ultrasonic washing, drying and smoothing, surface roughening and mechanical rolled flattening. The invention has the characteristics of simple technology, low cost, extensive application of the plant leaves after being processed, environmental protection, no pollution, superior degradable performance and the like.

Description

technical field [0001] The invention relates to the field of environment-friendly materials, in particular to a treatment process for plant leaves used as environment-friendly materials. Background technique [0002] In the prior art, environmentally friendly materials have been gradually applied in various fields, especially in packaging materials, daily containers, fresh-keeping materials and other fields. In the past, most of the packaging materials were plastic, paper, wood, etc. However, the raw materials used in plastic products mainly come from petroleum resources. Since petroleum resources are non-renewable resources, plastic packaging materials will cause energy waste. What's more serious is that ordinary plastics are often difficult to degrade, and due to the wide application of plastic packaging materials, the "white pollution" caused by waste plastics abandoned in nature has seriously threatened the living environment of human beings.

However, the raw materials used in plastic products mainly come from petroleum resources. Since petroleum resources are non-renewable resources, plastic packaging materials will cause energy waste

What's more serious is that ordinary plastics are often difficult to degrade, and due to the wide application of plastic packaging materials, the "white pollution" caused by waste plastics discarded in nature has seriously threatened the living environment of human beings. How to prevent and control "White pollution" has attracted the attention of countries all over the world. At present, the research and development of degradable packaging materials is an important way for people to devote themselves to solving "white pollution".

Although people have developed degradable plastics with better degradation performance, there are still some significant defects in these degradable plastics.

Specifically: if the degradable plastic is a starch-based degradable plastic, in today’s increasingly scarce food, the starch-based degradable plastic will undoubtedly cause food consumption and pose a threat to food reserves; if the degradable plastic is a photodegradable degradable plastic , the change of its chemical substances during the degradation process will also pose a potential threat to the environment

As for paper-based packaging materials, since papermaking needs to obtain raw materials by cutting bamboo and wood, the cost is relatively high; in addition, the papermaking process is likely to cause environmental pollution and damage the living environment of human beings.

Moreover, bamboo and wood packaging materials are often expensive, which largely limits their further application as environmentally friendly materials.
