Changes in production materials of peach protection bags

I. Traditional peach protection bag materials and their limitations
In the early stages of the development of peach protection bags, the main production materials were newspapers and plastic bags. Although newspaper bags are easy to obtain and low-cost, their protective effect is limited and they are easily washed and damaged by wind and rain. At the same time, they do not have the function of preventing insects and diseases. Plastic bags were widely used at the time for their good light transmittance and certain dustproof effects. However, plastic bags have poor air permeability, which can easily lead to excessive temperatures in the bag and burn the fruit; in addition, plastic bags are not easy to degrade, causing serious environmental pollution and not in line with the concept of sustainable development.

II. Improvement of environmental awareness and material changes
In recent years, with the improvement of consumers' awareness of environmental protection and the continuous strengthening of the country's environmental protection policies, the production materials of peach protection bags have also begun to shift towards environmental protection and degradability. This change not only meets the needs of the market, but is also an inevitable choice for manufacturers to respond to national environmental protection policies and fulfill their social responsibilities.

1. Improvement of paper materials
In response to the limitations of newspaper bags, special peach paper bags have appeared on the market. These paper bags are made of light yellow special paper, which has good wind and rain resistance. At the same time, the surface wax layer is thick, which can prevent rainwater from directly penetrating into the bag and protect the fruit from diseases. In addition, the production efficiency of special paper bags is high, and the specifications are diverse. You can choose the right bag according to the growth of fruit trees and the actual needs of the fruit. However, although paper materials are more environmentally friendly than plastic bags, they have poor light transmittance, which may affect the coloring and quality of the fruit.

2. Application of biodegradable materials
In order to solve the problem that plastic bags are not easy to degrade, biodegradable materials are introduced into the production of peach protection bags. These materials mainly include biodegradable plastics such as PLA (polylactic acid), PBAT (polybutylene adipate/terephthalate), and PHA (polyhydroxyalkanoate). These materials not only have good physical properties, such as light transmittance and toughness, but more importantly, they can be decomposed by microorganisms in the natural environment and will not pollute the environment. The application of biodegradable materials not only meets environmental protection requirements, but also improves the market competitiveness of peach protection bags.

3. Innovation of composite materials
In addition to paper materials and biodegradable materials, composite materials have also become a new choice in the production of peach protection bags. Composite materials are usually composed of a variety of materials, such as paper and plastic composites, biodegradable plastics and natural fibers composites. These composite materials combine the advantages of different materials, such as good air permeability, light transmittance, wind and rain resistance and degradability, etc., and can more comprehensively meet the use needs of peach protection bags.

III. Advantages and challenges of new peach protection bag materials
1. Advantages
Environmental protection: New peach protection bag materials such as biodegradable plastics and composite materials can be decomposed by microorganisms in the natural environment and will not cause pollution to the environment.
Functionality: These materials not only have good physical properties, such as light transmittance and toughness, but can also be customized according to the actual needs of the fruit, such as setting up rainproof and dustproof eaves and exhaust micropores.
Economical: Although the cost of new materials is relatively high, with the advancement of technology and the application of large-scale production, its cost is expected to gradually decrease. At the same time, the use of these materials also improves the quality and yield of fruits, thereby increasing the economic benefits of fruit farmers.
2. Challenges
Cost control: The cost of new peach protection bag materials is relatively high, and manufacturers need to reduce costs through technological innovation and large-scale production.
Technical difficulty: The production of composite materials requires a high level of technology and production equipment support, which may be technically difficult for some small manufacturers.
Market acceptance: Although consumers' demand for environmentally friendly products is increasing, the market acceptance of new peach protection bags needs to be further cultivated and improved.
