Why Pulp Molded Packaging is Better than Plastic Packaging？
Introduction
Exploring Sustainable Choices: Why Pulp Molded Packaging is Overtaking Plastic in the Packaging World.
Basic Introduction of Pulp Molded Packaging and Plastic Packaging
Pulp Molded Packaging
molded packaging is made from recycled paper products and is entirely biodegradable. The production process involves mixing recycled paper with water to create a slurry. This slurry is then molded into desired shapes and dried. The result is a lightweight, environmentally friendly packaging solution.
Plastic Packaging
Plastic packaging, on the other hand, is derived from petroleum products. It involves the process of polymerization or polycondensation and is known for its durability and versatility. However, its production is energy-intensive and it is not biodegradable, leading to long-term environmental impact.
Environmental Impact Comparison Test
1.Biodegradability Test
- Pulp Molded Packaging
Pulp molded packaging made from materials like sugarcane bagasse, straw, and mycelium, demonstrates significant biodegradability. Studies have shown that molded pulp products, when covered in unsterile soil, can lose up to 20% of their mass in just 4 weeks. This rapid degradation is a stark contrast to plastics, highlighting its environmental friendliness and reduced impact on landfill waste.链接
- Plastic Packaging
Plastic, on the other hand, is known for its lack of biodegradability. A staggering amount of the plastics produced end up in landfills or the natural environment, taking decades or even centuries to decompose. This accumulation contributes to severe environmental pollution and wildlife hazards.

2.Energy Consumption Test
- Pulp Molded Packaging
TWhile the production of pulp molded packaging can be energy-intensive, especially during the dewatering and drying stages, it generally consumes less energy than plastic packaging production. The use of recycled and natural fibers in pulp molded packaging also contributes to a lower overall carbon footprint compared to plastics.
- Plastic Packaging
The production of plastic packaging primarily uses electricity and natural gas, accounting for a significant portion of the total U.S. energy consumption. The high energy demand of plastic manufacturing contributes to higher carbon emissions and exacerbates environmental concerns.链接 链接

Application Scenarios Analysis
Food Packaging
Pulp Molded Packaging
Highly suitable for food packaging due to its non-toxic, biodegradable nature. It's safe for food contact and has minimal environmental impact after disposal.
Plastic Packaging
Some types may contain harmful chemicals, posing risks to food safety. Though it offers better protection and durability, the environmental concerns and potential health risks are significant drawbacks.
