Understanding <a href="https://www.ds-epsmachine.com/foam-fruit-box-mould"><b>Foam Fruit Box Mould</b></a>s: Materials and Solutions

Introduction

Foam fruit box moulds are essential in the agricultural packaging industry, providing protective enclosures for fruit during transport. These moulds are typically manufactured from expanded foam materials, which provide cushioning and structural support.

Material Composition of Foam Fruit Box Moulds

The primary material used in the production of foam fruit box moulds is Expanded Polystyrene (EPS). EPS is chosen for its lightweight properties, thermal insulation, and shock absorption capabilities. Alternative materials can include:

  • Polyurethane Foam (PU): Known for its flexibility and durability.
  • Expanded Polypropylene (EPP): Offers improved recyclability and resilience.
  • Biodegradable Foams: Made from plant-based resins, reducing environmental impact.

Manufacturing Process

The production of foam fruit box moulds involves several key steps:

  1. Pre-expansion: Expanding raw polystyrene beads using steam to increase their volume by 40-50 times.
  2. Moulding: The expanded beads are placed in a mould where they are shaped into the desired form using heat and additional steam.
  3. Curing: Allowing the moulded foam to harden and set into a robust structure.

  • Density: EPS commonly has a density range of 10-30 kg/m³, balancing strength and weight.
  • Compression Strength: Typically ranges from 70 to 200 kPa, providing the necessary protection during transport.
  • Thermal Conductivity: Low thermal conductivity of 0.035 W/m·K helps in maintaining fruit freshness.

Conclusion

Foam fruit box moulds play a critical role in the fruit supply chain, offering protection and durability. With advancements in material technology and manufacturing processes, companies like Dongshen are leading the way in providing sustainable and high-performance solutions.
