When B2B buyers reference "high pressure" specifications for dried fruit packaging, there's a critical technical distinction that determines product safety and shelf life. Unlike juice or ready-to-eat meals where HPP (High Pressure Processing) at 300-600 MPa (43,000-87,000 psi) serves as a non-thermal pasteurization method, dried fruits present fundamentally different requirements due to their low water activity.
For dried fruit exporters on Alibaba.com, "high pressure" specifications should instead focus on vacuum seal integrity and packaging material pressure-resistant performance (pressure resistance during storage and transport). The relevant technical parameters include seal strength (ASTM F88 standard), oxygen barrier properties (OTR <1.0 cc/m²/day), and moisture vapor transmission rate (MVTR <0.1 g/m²/day).
We keep our dried fruits in large plastic jars because we have the jars. (Sam's Club nuts). I keep the dried watermelon in the spare fridge. Because it is so very high in sugar, but the rest sit on a shelf and in the pantry. I've lost a jar or 2 of pears that we harvested off the tree in the backyard. They probably weren't dried enough, and a little bit of damp goes a long way in a sealed container. [5]
This Reddit user's experience highlights the core challenge: moisture control is paramount. Even in sealed containers, insufficient drying leads to mold growth. For B2B suppliers selling on Alibaba.com, this translates to three non-negotiable quality checkpoints: final product moisture content (typically 20-33% depending on fruit type per USDA specifications), packaging seal integrity verification, and appropriate oxygen absorber or desiccant inclusion based on fruit sugar content.
