“…The effect of plastic on the evolution of the milk marketing system provides a pertinent example of emerging complex secondary mechanisms where positive outcomes of value exchange led to constrained and compromised choice for individuals (refer Table 1). As plastics technology progressed, heavy fragile glass containers in the milk industry were replaced with lightweight, variable sized plastic bottles that offered significant price and durability advantages (Kontominas 2010). Vendors were no longer required to pick up the glass bottles from homes and hence home delivery ceased.…”

The purpose of this conceptual paper is to examine the mechanisms of long term marketing system failure from a path dependent, marketing systems perspective in order to identify ways of avoiding such situations in future. Using the model of Layton and Duffy (2018) we critically analyze the current plastic packaging crisis and its evolution over time. Through examining the mechanisms of failure from a systems perspective, we extend the path dependent, marketing system evolution model and advance understanding of marketing system failures. As a result of this analysis, the paper provides five propositions regarding where failure occurs within the system and identifies critical junctures where intervention (self-organized stakeholder initiatives and/or public policy intervention) can facilitate desirable outcomes in the future.

“…Milk cartons, among the most popular packages for milk, are coated with a polymer on both sides, in order to protect/isolate the contents from ambient air and chemical environments. PE-coated paperboard is the typical constituent of milk cartons; 17 microscopic photographs of the structure and thickness of each layer of a carton are shown in Fig. 1(b).…”

“…Pasteurized milk shelf‐life defines as “the period of time that pasteurized milk can be kept under refrigeration and still retain acceptable organoleptic and microbial quality” (Ungure et al, ; Pinto et al, ). To determine shelf‐life potential, FDA regulation limit for microbial load of pasteurized milk (20,000 cfu/mL) was considered (Kontominas, ). In this regard, freshly produced pasteurized milk was packaged in 5 cm × 7 cm sachets made from the fabricated multi‐layer active films and held at marginal refrigeration temperatures of 5–6°C and evaluated by microbiological [Standard Plate Count (SPC)] testing during 9 days of storage (4 days of expire date plus 5 days).…”

Objectives:The main aim of this study was to evaluate the effect of antimicrobial films on the shelf life of pasteurized milk. Methods: A natural antimicrobial agent, cinnamaldehyde, was incorporated in 0.5%, 1.0%, 1.5% and 2% concentrations in the middle layer of low density polyethylene (LDPE) three layer films by an extrusion process. Thickness of the inner layer were adjusted to 30 mm, 45 mm, and 60 mm and 2% PEG were added to some of the inner layer formulations. Active pillow packaging (5 cm 3 7 cm) with 16 different formulas were obtained from the fabricated three layered active films by thermo-welding process and filled with pasteurized milk and stored at 48C for 9 days. In order to see the effect of the active films on pasteurized milk quality, changes in total microbial counts monitored during the storage period. Results: During extrusion process, the mass loss of cinnamaldehyde were six times lowered when it was entrapped in the polymer matrix. All types of fabricated active films contributed to a reduction of total CFU growth rates in the pasteurized milk, when compared to plain (control) PE film, but the films coated with a thinner inner layer and films containing 2% PEG in the inner layers had a more pronounced effect than did the other films in inhibiting bacterial growth. Moreover, considering the five point hedonic scale sensory tests, film formulation number OM 2 I 4 selected as the best one and its physical properties were compared to the control film. PRACTICAL APPLICATIONSConsidering the daily high usage of pasteurized milk in most countries and regarding the short shelf life and perishable properties of this food product, using of multi-layer active films containing cinnamaldehyde (a natural antimicrobial) for packaging of pasteurized milk can extend its typical shelf life (4 days) to 6 days at 48C of storage.
