Wet-strength kraft paper: Why it has become a new choice for plant cultivation, do you know the reasons?

1. Material characteristics of wet-strength kraft paper
The key to wet-strength kraft paper's ability to maintain high strength in a humid environment is the special treatment of its material. Compared with ordinary kraft paper, wet-strength kraft paper adds wet-strength agents during the manufacturing process. These wet-strength agents are usually chemicals such as thermosetting resins. These chemicals form stable chemical bonds between paper fibers, allowing the paper to maintain a close bond between fibers after absorbing water, thereby greatly enhancing the wet strength of the paper.

Wet-strength kraft paper also uses high-quality wood pulp as raw material to ensure the basic strength of the paper. The wood pulp is carefully selected and processed to remove impurities, making the paper purer and more uniform. This high-quality raw material selection lays a solid foundation for the excellent performance of wet-strength kraft paper.

2. The difference between wet-strength kraft paper and ordinary kraft paper

There are significant differences between wet-strength kraft paper and ordinary kraft paper in many aspects. Wet-strength kraft paper has higher wet strength and can maintain stable performance in a humid environment, while ordinary kraft paper tends to soften and crack after absorbing water. Wet-strength kraft paper usually has higher whiteness and better printing effect, which makes it more widely applicable in packaging, labeling and other application fields.

Wet-strength kraft paper also has relatively high burst resistance and tear strength, and can withstand greater pressure and impact. This feature makes wet-strength kraft paper excellent in protecting the contents from damage, especially in situations where long-distance transportation or storage is required.

3. Benefits of using wet-strength kraft paper in plant planting

In the field of plant planting, wet-strength kraft paper also plays an important role. First of all, wet-strength kraft paper can be used as a material for plant seedling bags. Due to its high wet strength and burst resistance, the seedling bag can remain stable in a humid soil environment, providing sufficient growth space and protection for the seedlings. At the same time, wet-strength kraft paper has good air permeability, which is conducive to the root development and growth of seedlings.

Wet-strength kraft paper is used to make plant covering materials. In horticulture and agricultural production, covering materials can protect plants from wind, frost, rain and snow, while maintaining soil temperature and humidity. As a covering material, wet-strength kraft paper not only has excellent waterproof properties, but also can effectively reflect sunlight, reduce soil temperature, and provide a more suitable growth environment for plants.

Wet-strength kraft paper is also an environmentally friendly and recyclable packaging material. Using wet-strength kraft paper in the process of plant cultivation can reduce dependence on non-degradable materials such as plastics and reduce environmental pollution. The recycling and reuse of wet-strength kraft paper is in line with the concept of sustainable development and helps promote the development of green agriculture.
