Application

Design takeaway

Incorporate targeted ventilation features into packaging designs for perishable goods, and leverage simulation tools to predict and validate performance under various environmental conditions.

How to apply

When designing packaging for fresh produce, consider the use of materials and structural designs that facilitate airflow and minimize internal condensation, and use simulation tools to predict the impact of these design choices on product longevity.

Project actions

01When designing packaging, think about how air can move through it to keep the contents dry and cool.
02Use computer simulations to test how your packaging design might perform before you make a physical prototype.

Method & Evidence

AimTo compare the performance of different strawberry packaging types (top-sealed paperboard, open plastic clamshell, closed plastic clamshell) in maintaining fruit quality throughout a simulated supply chain, using a combination of experimental testing and mechanistic modeling.

MethodCombined experimental and simulation-based approach.

ProcedureThree packaging types were tested in a climate chamber simulating farm-to-retail conditions. Quality metrics such as mass loss, soluble solids, acidity, firmness, color, and decay incidence were measured. Physics-based digital twin models of the strawberries and packaging were developed using sensor data to simulate hygrothermal and physiological evolution, quantifying condensation, respiration-driven quality, and remaining shelf life.

ContextFood packaging and supply chain logistics for perishable produce.

Variables

IVPackaging type (top-sealed paperboard, open plastic clamshell, closed plastic clamshell).

DVFruit mass loss, total soluble solids, acidity content, firmness, color change, incidence of decay, time of wetness, respiration-driven overall fruit quality, remaining shelf life.

CVClimate chamber conditions (temperature, humidity), simulated supply chain duration, type of fruit (strawberries).

Strengths & Limitations

Strengths

+Integration of experimental data with mechanistic modeling provides a comprehensive understanding of packaging performance.
+Simulation of a full supply chain scenario offers practical relevance.

Limitations

The experimental setup might not perfectly replicate all real-world supply chain variables, and the models are simplifications of complex biological and physical processes.

Reliability & validity

The study's reliability is enhanced by combining experimental measurements with simulation, providing a cross-validation of findings. Validity is strong in its direct measurement of quality metrics and simulation of relevant supply chain conditions.

Think critically

To what extent can the findings from this controlled laboratory study be generalized to the complexities of real-world, dynamic supply chains with varying handling and storage conditions?

Design Principles

"Optimize hygrothermal management through strategic ventilation to extend the shelf life and maintain the quality of perishable products."

Understanding the hygrothermal dynamics within packaging is crucial for preserving perishable goods. This research provides a robust framework for evaluating packaging performance, moving beyond simple observational metrics to predictive modeling that can inform material selection and design for extended product viability.

What This Means for Your Design

This study shows that a paperboard box with air holes kept strawberries fresher for longer than plastic containers because it stopped moisture from building up inside.

The research by Schudel et al. (2022) highlights the significant impact of packaging ventilation on the shelf life of perishable produce. Their findings, supported by both laboratory experiments and mechanistic modeling, demonstrate that strategic airflow can effectively mitigate condensation and temperature fluctuations, leading to improved product quality and reduced spoilage. This underscores the importance of considering hygrothermal dynamics in packaging design for items like strawberries.
