In the fresh fruit export industry, particularly for Longan, packaging serves not merely as a container but as a critical technical factor determining the final product quality. At Sunshine, we implement rigorous packaging standards based on the biological characteristics of the fruit to overcome the limitations of traditional bulk methods.

 

Technical Analysis: Shell Characteristics and Preservation Risks
Despite possessing a thicker shell compared to many other fruits, the Longan shell is, in reality, the most sensitive component during cold storage.

Dehydration Mechanism: Post-harvest respiration continues after picking. In cold storage environments lacking precise humidity control, the shell dehydrates rapidly, leading to desiccation and brittleness.
Micro-cracking Phenomenon: Once the shell becomes desiccated, any external compressive force can induce micro-cracks. This serves as a direct entry point for air, leading to the oxidation of the pulp. Consequently, the flesh softens, loses its characteristic crispness, and degrades in flavor profile.

Therefore, the critical challenge for exporters is to maintain ideal humidity levels while eliminating compressive stress on the fruit throughout the supply chain.

The Sunshine Solution: Specialized Packaging Standards

To address these challenges, Sunshine has moved beyond traditional mesh bags or bulk cartons, adopting high-specification packaging protocols to ensure commercial quality:

1. Micro-Climate Control with Specialized Punnets The utilization of specialized plastic punnets provides superior preservation efficacy compared to standard netting:

• Humidity Stability: The punnet design helps maintain a stable local humidity level (micro-climate) around the fruit, significantly minimizing shell cracking caused by desiccation or thermal shock.
  • Physical Protection: The rigid structure of the punnets immobilizes the longan clusters, preventing direct impact and friction between fruits during transit.

1. Ensuring Structural Integrity with Heavy-Duty V-Boards For long-haul sea freight, cargo stability is paramount. Sunshine reinforces every export pallet with a system of Heavy-duty V-Boards (Corner Guards).

• Load-Bearing Mechanism: The V-Board system creates a rigid skeletal structure, effectively distributing the vertical load of stacked layers down to the container floor rather than onto the fruit cartons.

Efficiency: This ensures that cartons remain perfectly square and free from crushing or deformation, providing absolute protection for the product inside against compressive stress.

Investing in premium packaging solutions is Sunshine’s strategic commitment to product quality. We guarantee that every shipment of Master Longan reaching our import partners retains the freshness, texture, and original flavor integrity found at the orchard.
