Pulp molding is a three-dimensional papermaking technology. It uses waste paper, wood pulp, various types of straw pulp, and other materials as raw materials. With molds equipped with filters, specific-shaped paper products are formed on molding machines using special molds. It can be made into model products of various shapes according to different uses, mainly including cushioning packaging materials, pulp-molded agricultural products, pulp-molded material products, disposable tableware, etc. Then, what are the main characteristics of pulp molding products?
Pulp molding products mainly have the following characteristics:
- They belong to "green packaging" and involve no pollution or other hazards in the production process. They are easy to recycle after use; even when discarded, they can decompose naturally. Just like any other paper products, they can return to nature without harming it.
- Wide source of raw materials and low cost. They are mainly made from waste paper and part of virgin pulp, so the raw materials are easily available and the production cost is low.
- High strength, good plasticity, and excellent cushioning performance.
- Light weight, low recycling cost, and reusability.
- Good protective, interchangeable, and decorative properties.
- Stiffness can be improved by adding different additives, and it has good bending resistance and crack (tear) resistance.
- Good breathability, which is of great significance for the packaging of fresh products.
- Modern production technology enables high-speed automated mass production.
- Pulp molding products have good water absorption, hydrophobicity, and heat insulation.
- Wide application range.
The above is an introduction to the main characteristics of pulp molding products. With the development of society, the social demand for pulp molding products is constantly expanding. Since its manufacturing process is similar to the papermaking industry, it also belongs to a high-energy-consuming industry. However, large-scale production is necessary to meet social demand. Therefore, how to reduce energy consumption has become an urgent issue for this industry. After all, reducing the unit energy consumption will bring huge economic and social benefits to enterprises.
