Pulp-molded products have good sales in the market. Making pulp-molded products requires appropriate raw materials and suitable pulp molding equipment, processed through specific procedures. Today, let’s briefly discuss pulp-molded raw materials.
Pulp Molded Raw Materials
Pulp Molded Raw Materials can be broadly categorized into two types: Virgin Pulp (Pulpboard) and Waste Paper Materials.
Virgin pulp, often referred to as pulpboard, is a primary source of raw materials for the production of pulp-molded products. It’s produced from chemical wood pulp, which can be bleached to different grades, including high, medium, and low. The choice of grade depends on the intended application. High-grade virgin pulp is typically reserved for products that require a premium appearance and quality, like packaging materials for luxury goods or specialty paper products.
Waste Paper Materials
Waste paper materials are a sustainable and cost-effective alternative for pulp molded products. They are widely available and help in reducing the environmental impact of paper production. In China, waste paper materials are sourced from various channels:
White Waste Paper: This category is especially valuable as it can serve as a substitute for virgin pulp. It includes pristine, unprinted white paper that possesses consistent whiteness and is free from harmful substances. After undergoing shredding and processing, white waste paper can be used for a range of applications, including general writing and printing paper, premium hygiene paper, and high-quality printing products.
Book and Magazine Waste Paper: Waste paper from books and magazines is a common source of raw materials for pulp molding. De-inking and ink removal processes are applied to prepare this material for recycling. Once processed, it can be used to produce glossy paper, writing paper, offset printing paper, and hygiene products such as tissue and paper towels.
Old Newspapers: Old newspapers can find a second life in the paper industry after suitable treatment. They are repurposed for the production of cultural and household paper products, contributing to the recycling loop.
Paperboard and Cardboard Waste: Materials from discarded paperboard, corrugated paperboard, and old corrugated cardboard are excellent sources of raw materials. These include remnants from products like kraft paperboard, corrugated paperboard, old corrugated cardboard boxes, and cartons. They can be reprocessed to create a variety of pulp-molded products, including packaging materials and protective solutions.
Waste paper materials are not only eco-friendly but also cost-effective, making them a preferred choice for the production of items like egg trays, fruit packaging, and a wide range of other disposable and recyclable products. The versatility and sustainability of these materials are significant factors contributing to their popularity in the pulp molding industry.
