Pulp molding (commonly known as paper tray), referred to as PMP, now mainly uses raw materials such as sugarcane bagasse and bamboo residue, assisted by waste newspapers, recycled carton paper, paper tubes, pure wood pulp, etc., and is mixed into a certain proportion of concentrated slurry through processes such as pulping and pulping. The slurry is placed on a special mold, and vacuum adsorbed into a wet pulp semi-finished product, and then dried and hot-pressed to form various lined environmentally friendly packaging products.

"Pulp molding" is the scientific name and "paper support" is the common name.


Pulp molding is a new type of environmentally friendly product packaging material.

Characteristics of Pulp Molded Packaging


1. Environmental protection

Pulp molding products use bagasse, bamboo residue, waste newspapers and magazines, and carton paper as the main raw materials. They are made into paper after a certain ratio, and then dehydrated and formed through specially made molds, and then go through a series of processing processes such as air drying, heat treatment, shaping and trimming.

Pulp molded products are recyclable and biodegradable. After adding a unique processing technology, they have excellent moisture-proof and oil-resistant properties. They can completely replace foam products and completely eliminate "white waste". The products are environmentally friendly. Pulp molded products are green and environmentally friendly products strongly recommended by the Environmental Protection Agency of the World. During their processing, they attach great importance to environmental protection. As for the harm of the three wastes to the environment, throughout the entire processing process, from the use of key raw materials to the end of the entire processing process, their environmental protection awareness is very strong.

Its raw materials are bagasse, bamboo residue, waste paper, etc., and the production process is mainly physical reaction, with only a small amount of chemical substances added as waterproof coating. After the product is dried, most of these chemical raw materials are retained in the finished product and are not discharged to cause environmental pollution. The production line water is used in a closed loop system, and only water vapor is evaporated into the air when the product is dried. There is no need to add water during the processing, so the water demand is also very small.

2. Suitable for the economic transformation of enterprises

After years of development, domestic innovation, continuous improvement of equipment performance, and gradual improvement of production process, pulp molding technology has stabilized product costs. At present, the cost of paper tray products in China is basically the same as that of plastic foam products, and the cost of some paper tray products is lower than that of plastic foam products. Paper tray products replace plastic foam anti-seismic products, which has feasibility analysis in terms of performance indicators and product costs. In addition to its advantages in environmental protection, pulp molding products have replaced plastic foam products and have become an inevitable trend.

3. Eco-Friendly and Sustainable

Pulp molded packaging is made from recycled paper and natural fibers, making it biodegradable and compostable. This environmentally friendly characteristic significantly reduces waste and carbon footprint, aligning with sustainable business practices.

4. Protective and Durable

Despite its eco-friendly materials, pulp molded packaging is incredibly durable. It provides excellent cushioning and protection, absorbing shocks and impacts to safeguard delicate items during transit. Its robust design ensures that products arrive in perfect condition.

5. Customizable Designs

One of the standout features of pulp molded packaging is its versatility. It can be molded into various shapes and sizes, tailored to fit specific products. This customization enhances product presentation and ensures a snug, secure fit, reducing the risk of damage.

6. Cost-Effective

The manufacturing process of pulp molded packaging is relatively low-cost compared to other packaging materials. Its lightweight nature also reduces shipping costs, offering a cost-effective solution for businesses looking to optimize their packaging expenses.

7. Versatile Applications

Pulp molded packaging is suitable for a wide range of applications, from electronics and consumer goods to food and beverages. Its adaptability makes it a preferred choice for various industries, providing a practical and efficient packaging solution.

8. Moisture Resistant

Advanced manufacturing techniques can make pulp molded packaging moisture-resistant, extending its usability to environments where exposure to moisture is a concern. This characteristic enhances its protective capabilities and broadens its application range.

In conclusion, pulp molded packaging combines sustainability, protection, customization, cost-effectiveness, versatility, and moisture resistance. These characteristics make it an ideal packaging solution for businesses committed to reducing environmental impact while maintaining high standards of product protection and presentation.
