Wet-pressed molded pulp
Wet-pressed molded pulp is an eco-friendly packaging material made from natural plant fibers. Typically using renewable resources such as recycled paper pulp, bagasse, bamboo pulp, or wood fibers as its base, this type of packaging is formed while the pulp is still wet.
Through high-temperature and high-pressure molding, it is shaped with precision, resulting in a smooth and refined surface. Today, it is widely used for premium inner packaging of smartphones, 3C electronic devices, tablets, and more — making it a preferred sustainable packaging solution for leading international tech brands.
Features of Wet-Pressed Molded Pulp
Wet-pressed molded pulp trays are paper-based products manufactured through wet forming processes.
Their key characteristics and applications include
High Strength and Durability
Engineered with specialized processing techniques, wet-pressed trays offer excellent strength and durability, capable of withstanding considerable weight and pressure.
Superior Moldability
The wet forming process allows for versatile shaping, enabling the creation of various forms and structures with high design flexibility.
Eco-Friendly and Biodegradable
Made from naturally degradable paper materials, these trays meet environmental standards and decompose without polluting the environment.
Advantages of Wet-Pressed
vs. Dry-Pressed Molded Pulp
Appearance
Wet-pressed trays boast a smooth finish on both sides, molded precisely between top and bottom dies. The surface is sleek, free from roughness or lint.
Product Precision
Thanks to CNC-machined molds, minimal corner radii down to 20° are achievable with exceptional accuracy—ensuring snug protection for every product contour, like a well-fitted garment.
Moisture Resistance
With a controlled drying process, the trays retain minimal moisture, preventing deformation during storage due to humidity.
Raw Materials
Crafted from bagasse, wood pulp, and various plant fibers, the materials are environmentally friendly and available in multiple colors to suit different preferences.
Application Fields
Food Packaging
Its strength and absorbency make wet-pressed pulp trays ideal for packaging frozen foods, fresh produce, and more.
Agricultural Use
These trays serve well as seedling trays or plant bedding, providing a nurturing growth environment.
Medical Supplies
Widely used in packaging medical devices to ensure hygiene and cleanliness.
Electronics (3C) Packaging
Valued for their anti-static properties and refined appearance, wet-pressed trays are favored by major global electronics brands. Available in brown, white, and black for premium 3C product packaging.
Industrial Packaging
Suitable for securing components during transport, protecting them from damage.
