“…76,77 Packaging also represents the packaged food prior to purchase, so packaging design and material selection must be carefully determined. 78,79 Still in relation to design, marketers can use packaging with simple or complex aesthetics. This is essential for these professionals to understand which types of packaging attract the attention of consumers.…”

The limited degradation of synthetic polymers used in food packaging when discarded in the environment is a major concern for society. Therefore, industry and academia have sought to develop biodegradable and eco-friendly materials for single-use in packaging. An interesting alternative for the food industry is biodegradable polymeric films, which is why different biopolymers have been used in the production of sustainable packaging. It is worth mentioning that the use of biodegradable polymers is one of the most successful innovations in the industry to address issues related to the environment. Among the available raw materials, starch extracted from different renewable sources is very promising for this purpose, due to its abundance, low-cost compared to other polymers and ability to produce non-toxic films. However, when used alone, pure starch has many limitations, which can be overcome by developing a mixture with other polymers (polymer blends), preferably from renewable and biodegradable sources, such as poly(lactic acid) (PLA). In this context, the absence of literature reviews evidencing the results of the application of films in foods led us to write this article, given the importance of polymer blends produced with different types of starch (cassava, corn, pea, potato, rice and wheat) and the PLA matrix. According to the results, it is clear that polymer blends based on PLA/Starch for food packaging are very promising, already being part of the industries solutions, aiming to minimize the large volume of plastic waste of petrochemical origin discarded in nature. Obviously, as with any technology, more research is needed to further improve the performance of the films, and while much research has made great strides, there are still limitations that prevent the commercialization of these materials.

“…There can be several reasons for this: tab-like cutouts, ventilation holes/openings (mainly for agricultural products), viewing windows, etc. These solutions have a negative influence on the compression strength of the boxes, and this phenomenon was investigated by several authors [ 8 , 30 , 31 , 32 , 33 , 34 , 35 , 36 ].…”

Compression Strength Estimation of Corrugated Board Boxes for a Reduction in Sidewall Surface Cutouts—Experimental and Numerical Approaches

2023

Corrugated cardboard boxes are generally used in modern supply chains for the handling, storage, and distribution of numerous goods. These packages require suitable strength to maintain adequate protection within the package; however, the presence and configuration of any cutouts on the sidewalls significantly influence the packaging costs and secondary paperboard waste. This study aims to evaluate the performance of CCBs by considering the influence of different cutout configurations of sidewalls. The compression strength of various B-flute CCB dimensions (200 mm, 300 mm, 400 mm, 500 m, and 600 mm in length, with the same width and height of 300 mm), each for five cutout areas (0%, 4%, 16%, 36%, and 64%) were experimentally observed, and the results were compared with the McKee formula for estimation. The boxes with cutout areas of 0%, 4%, 16%, 36%, and 64% showed a linear decreasing tendency in compression force. A linear relationship was found between compression strength and an increase in cutout sizes. Packages with 0% and 4% cutouts did not show significant differences in compression strength (p < 0.05). Furthermore, this study shows a possible way to modify the McKee estimation for such boxes after obtaining empirical test data since the McKee formula works with a relatively high error rate on corrugated cardboard boxes with sidewall cutouts. Utilizing the numerical and experimental results, a favorable estimation map can be drawn up for packaging engineers to better manage material use and waste. The results of the study showed that the McKee formula does not appropriately estimate the box compression strength for various cutout sizes in itself.

“…4 The popularity of corrugated board packaging is due to its relatively low cost, ease of manufacture and transport, low net weight to strength ratio and high stiffness to drained net weight ratio. 5 Another major advantage of corrugated board is its easy recyclability, making it one of the most environmentally friendly packaging materials. 2,[6][7][8] On the other hand, corrugated paper board is the easiest and most recyclable packaging material with respect to any delivery destination.…”

One of the most important elements for animal transportation is the packaging that ensures the safety and health of the transit. During the transport of live small animals, such as day‐old chickens, the animals may only stay in the boxes for a very limited period, in this case, 48 h. Therefore, it is important to be able to model the strength behaviour of these boxes concerning packaging material requirements and sustainability. The aim of this study was to determine the short‐ and relatively long‐term strength of day‐old chicken packages to better estimate packaging design and to use these data to establish an analytical creep model with suitable parameters that adequately approximate the measured data. Two types of packages were tested, and two types of creep models were used to model the creep strain‐time graphs. The creep behaviour of the two samples was tested at four different uniaxial load cases, with consistent environmental conditions during the tests (23°C and 50% relative humidity [RH]). At the two highest loads, both samples failed before the 48‐h cycle, indicating a significant difference in box strength between short‐term and long‐term load tests. The secondary creep strain rate increases with the magnitude of the compressive load. When comparing the two creep models for both box types, the Power law provided the best accuracy at the 50% of box compression test (BCT) load case, while at the other three load cases, the Andrade law showed better predictions.
