The M-RULE® Container Performance Model for Foods was introduced in 2008. This subscription-based computer model is a powerful permeation model for predicting the performance of packaging for a variety of liquid and solid food products, as well as for complex food packaging (like bag-in-bag, bag-in-box, institutional packaging, etc.). This model is also used for packaging for electronics, pharmaceuticals, medical devices and industrial chemicals.
The M-RULE® Container Performance Model for Foods is based on the same materials, science, algorithms, and code developed for the M-RULE® Container Performance Model for Beverages—the industry standard tool for permeation prediction in the beverage industry since its introduction in 2002. Consequently, the Model for Foods benefits from the in-depth validation and features enhancements of that model.
A powerful feature of the M-RULE® Container Performance Model for Foods is its ability to accurately predict temperature-dependent and product-dependent moisture sorption as a function of relative humidity and food composition (using only carbohydrate, protein, and fat content of each product). This eliminates the need for empirical moisture sorption vs. relative humidity measurements at different temperatures.
The M-RULE® Container Performance Model for Foods predicts the glass-transition temperature of the food product (where the food loses its crispness), which provides the user with an independent, non-empirical prediction of upper and/or lower moisture targets.
The M-RULE® Model inherently accounts for all the factors that affect permeation, including concentration-dependent diffusion, temperature, polymer crystallinity, orientation, stress, and stress relaxation. The model simultaneously calculates the migration of O2, N2, CO2 and H2O and continually revises the diffusivities and solubilities of each of these permeants as a function of the above factors.
The M-RULE® Container Performance Model for Foods incorporates vitamin degradation and food respiration. It also predicts package expansion and contraction as a function of internal and external pressure and polymer modulus. It includes all the major barrier technology options, including plasma coatings, oxygen scavengers, multilayers, blends, and nanocomposites.
Furthermore, this M-RULE® model allows the user to assess the impact of package design, filling, storage and distribution conditions on product shelf-life.
The M-RULE® approach to permeation prediction is unique and proven. Unlike empirical models that rely on a database of permeation values to derive results, the M-RULE® model is a fundamental model based on first-principles prediction of the diffusion and solubility of gases. The M-RULE® Model calculations are based on the application of physical laws and fundamental science via numerical integration.
Because of this fundamental approach, the M-RULE® Model can simulate scenarios and provide predictions well beyond the range of test data available to empirical models.
M-RULE® is a powerful tool for new package development, strategic analysis of alternative technologies, assessment of competitive materials and packages, package authorizations, light-weighting programs with existing packages, barrier technology development, and materials research and development.
