High-fat content makes nuts particularly vulnerable to oxidation and rancidity. This technical analysis explores why brick shape vacuum packaging is the superior engineering response. We examine how a specialized nut vacuum packaging machine minimizes residual oxygen to protect unsaturated fatty acids. By utilizing high-barrier film packaging within an automatic vacuum sealing system, manufacturers can achieve shelf-life extensions of up to 100%. As a premier packaging machine manufacturer, we dissect the mechanical shaping process that provides structural rigidity.

In the quest for eco-friendly operations, manufacturers face a dilemma: choose standard biodegradable materials or prioritize product stability? This technical report analyzes the barrier properties of high-barrier film used in vacuum systems versus PLA/Corn Starch alternatives. We evaluate moisture resistance (WVTR), oxygen transmission (OTR), and structural integrity. As a premier packaging machine manufacturer, we explain why a vacuum packaging machine remains the superior engineering choice for product preservation, and how vacuum sealing technology is evolving to accommodate new materials within food packaging equipment.
