With the rapid development of the world economy and the gradual upgrade of the "global plastic ban", the call for paper instead of plastic is growing. Many environmentally friendly products, such as paper straws, biodegradable plastics, and biodegradable lunch boxes, have gradually become part of our daily lives, and molded paper pulp is one of them.
Molded paper pulp, also known as "paper tray", is a new environmentally friendly product made of renewable plant fibers manufactured into pulp and molded into specific molds. Molded paper pulp is a packaging material that is usually made from recycled cardboard or newspaper. It is used for protective packaging or food service trays and beverage carriers. Other typical uses are end caps, trays, plates, bowls, and flip-top containers. For many applications, molded paper pulp is cheaper than expanded polystyrene (EPS), vacuum-molded polyethylene terephthalate (PET), polyvinyl chloride (PVC), corrugated board, and foam materials. Molded paper pulp is often seen as a sustainable packaging material, defined by the Sustainable Packaging Alliance because it is made from recycled materials and can be recycled again after its useful life ends.
As a green, biodegradable, and environmentally friendly product, molded paper pulp has many advantages: the raw materials of the paper tray are widely available and grow quickly and are low-cost; it has strong air permeability and good water absorption, hydrophobicity, and thermal insulation, enabling it to preserve fresh products very well; it has a small volume and can be stacked, saving storage space and transportation costs; it has excellent cushioning ability, maximizing product protection; it has sound absorption, thermal insulation, and other characteristics, effectively reducing indoor noise. In addition to these, products also have acid resistance, alkali resistance, sun protection, waterproof, anti-static, oil resistance, and non-leakage capabilities.
Molded paper pulp has a wide range of applications. Based on the advantages of waterproof and oil-resistant paper-plastic packaging, it can effectively replace plastic packaging. We believe that it is the best choice for the replacement of traditional packaging, because the main raw materials of molded paper pulp include sugarcane pulp, bamboo pulp, reed pulp, and other grass pulp, as well as waste paper pulp, etc. At present, there are two types of processes for paper-plastic production - dry pressing and wet pressing. Wet pressing can meet the fine packaging with exquisite appearance, while dry pressing can meet the coarse tray application, producing versatile products. With advantages such as no tree cutting, low carbon emissions, and 100% biodegradability, it is an ideal choice for new environmentally friendly packaging materials. We look forward to seeing paper-plastic packaging replacing plastic packaging in the future and bringing everyone a more environmentally friendly life.
