Here are a few reasons why proper packaging is essential: Prolongs freshness: it helps reduce product interaction with air, moisture, and light—factors that contribute to the rapid deterioration of fruit and vegetables. This helps preserve the product's flavor, texture, and nutrients for longer; Reduces waste: it shields fruit and vegetables from mechanical damage and impacts during transport and handling. By minimizing damage and losses, food waste is significantly reduced; Prevents contamination: secure and hygienic packaging helps prevent contamination from external agents such as bacteria and other pathogens. This is especially vital for delicate items like leafy greens; Optimal moisture retention: some produce requires specific humidity levels to maintain freshness. The right packaging can help regulate internal moisture, preventing mold formation or product dehydration; Facilitates selection and identification: well-designed, clear packaging allows consumers to see the product without opening it, making selection and identification of desired items much easier; Environmental responsibility: reduces environmental impact and contributes to better waste management. Using recyclable or biodegradable materials helps cut down on pollution and plastic waste; Seasonal preservation: extends the availability of out-of-season fruit and vegetables, allowing produce to be imported and safely stored for longer periods; Promotes brand and product identity: eye-catching and well-structured packaging can help promote the product and increase its market visibility. Let us now discover the key tips for designing and manufacturing the perfect packaging for fruit and vegetables. Choosing the right materials Corrugated cardboard offers an excellent solution for preserving the freshness and presentation of fruit and vegetables. The multi-flute structure of the cardboard provides high protection against shocks and mechanical stress during transport and handling. The flutes absorb impacts, reducing the risk of damage. It is also a lightweight material, making it easy to handle and reducing the overall weight of the parcel, a beneficial factor for long-distance shipments as it can lower freight costs. The choice of corrugated cardboard type depends mainly on the kind of fruit and vegetables you want to pack and your storage requirements. For delicate or pressure-sensitive fruits, like strawberries or raspberries, it is recommended to use a thinner corrugated cardboard to reduce pressure on them; for hardier fruits like apples, you can opt for a thicker corrugated cardboard for greater protection. Furthermore, the packaging must feature: Suitable dimensions: the box must be spacious enough to contain the desired amount of fruit to avoid crushing during transit; Internal compartments: to prevent collision between fruits, keep them stable, and maintain their integrity; Breathability: the corrugated cardboard packaging must allow good air circulation. Breathability is particularly crucial for certain fruit varieties that require greater aeration to stay fresh. Storing at proper temperatures Some items require a cold environment, while others thrive at higher temperatures. Here are some general guidelines: Refrigerator: most vegetables should be stored in the bottom crisper drawer of the fridge, where the temperature is slightly higher and humidity can be regulated. More delicate fruit should be placed on the upper shelves, where the temperature is more constant; Control humidity: some refrigerators feature a dedicated drawer with humidity control for leafy greens. This helps maintain moisture at the optimal level to prolong freshness; Bananas and citrus fruits: oranges and lemons as well as bananas can be stored at room temperature, as the cold can alter their flavor and texture. Separating ripe produce from unripe produce Ripe produce releases ethylene gas, a plant hormone that accelerates the ripening of other items around it. This can lead to faster decay and waste. Therefore, it is best to store ripe produce separately from unripe products. Regularly checking storage status To avoid waste and ensure freshness, it is essential to regularly check the storage status of fruit and vegetables. Promptly discard any moldy, bruised, or decaying produce to prevent it from damaging the rest. By using appropriate packaging and following correct storage practices, you can keep fruit and vegetables fresh and tasty for longer. Always remember that proper storage not only improves food quality but is also a sustainable choice for the planet, helping to reduce environmental impact.

Packaging for the luxury segment is built and designed to convey brand values ​​by focusing on elegance and innovation. Nowadays, a new sensitivity regarding pollution and waste production, as well as the changed purchasing habits of consumers and the greater use of online stores, have given the sector new stimuli, offering the possibility for designers to experiment new solutions. So Packaging Première has promoted research aimed at understanding the evolution of qualitative trends that are emerging in the packaging user sectors. With the advent of the pandemic, there was a renewed interest in Made in Italy, both in terms of domestic consumption and in terms of the foreign market. In this sense, the packaging had the task of transferring those values ​​that are iconically linked to the excellent products of our country, such as elegance and tradition, but also innovation and originality. What are the characteristics of luxury packaging? The packaging used by brands operating in the luxury sector has always been strongly identifying the brand. The customer, therefore, recognizes himself in that specific product starting right from the packaging. Thinking of packaging variations different from the usual one can be harmful in terms of recognizing the distinctive features of the product. This strategy, therefore, can only be used for celebratory purposes, for example on the occasion of an anniversary or a limited edition. However, not all products are suitable for this type of operation. In addition to the desire to obtain a personalized and recognizable packaging, at the same time companies require the realization of projects that aim to protect the environment, combining the use of recycled materials with savings in the input phase and with the consumption of themselves. Furthermore, with regard to the use of the product by the final consumer, we can see that in Europe the sensory interaction between packaging and the consumer is privileged. This aspect is also evident in the difference in approach to colour, preferring a range of shades that bears the concept of naturalness in its essence, as happens, for example, for products in the food chain. What are the prospects that influence the production of luxury packaging? With the advent of the pandemic, the number of users who have turned to online commerce to satisfy their needs has increased. This trend could stabilize over the next few years. If in the past the tactile sensations regarding the composition material of the packaging could be an additional attraction, now it is necessary to conceive the packaging with an aesthetic capable of involving the potential buyer through the screen. The search for a new aesthetic will go hand in hand with the need to preserve functional characteristics. In this sense, also given the greater sensitivity of consumers towards issues concerning the environment, it will be the designers' responsibility to propose solutions that come to life from recycled materials, easily disposed of once they are placed in the circuit of use. The packaging of the future will be user-friendly, suitable for containing costs, thanks to the lightening of the raw material and the consequent lowering of transport costs. The new trends in luxury packaging As we have mentioned, the packaging is also designed on the consumer's habits. If at one time glossy finishes were synonymous with prestige, now they are mainly intended for foreign markets such as Russia and the Emirates. We tend to preserve processes that have important details that can give back pleasant tactile sensations. At the same time, attempts are made to limit or eliminate the use of multi-material packaging, to avoid integrating paper and plastic. As for printing, there is talk of a reduction in costs through the use of nanotechnologies, which have not yet found use in Italy. Finally, technological advances make it possible to obtain paper and cardboard packaging made from renewable sources or from processing waste, which undergo processes capable of making the packaging robust.

The evolution of packaging does not only occur in terms of sustainability: today, more and more often we talk about functional packaging, taking care to distinguish between: active packaging intelligent packaging But let's take one thing at a time and understand what the characteristics of functional packaging are, and when we are dealing with active packaging or intelligent packaging. What is meant by functional packaging? We are dealing with functional packaging when a material, container, or accessory that constitutes the packaging manages to serve multiple functions. The difference with traditional packaging lies in the fact that this packaging performs an additional function which, beyond mere containment, integrates and interacts with the content in order to improve its acceptability and shelf life. Functional packaging solutions are already in use in the food and pharmaceutical sectors, where the product must not only be preserved, but requires the packaging to perform an action that allows for the control of quality and the preservation state of the product itself. Active packaging and intelligent packaging: differences Among functional types of packaging are active packaging and intelligent packaging. Regarding active packaging, this expression refers to all those solutions that interact with the content by controlling the internal atmosphere. The material can release antimicrobials, antioxidants, and other useful substances that improve product quality. Intelligent packaging, on the other hand, is characterized by the presence of an indicator that can be positioned either inside or outside a package. The purpose of the latter is to actively represent the history of the product in relation to its quality level. What is the purpose of intelligent packaging? In this sense, the purpose of active and intelligent packaging is threefold since they must: reduce the rate of quality degradation provide protection from all possible contaminations be simple and practical to move and use For example, among the functions that can be attributed to intelligent packaging is the possibility to interact with the package environment and with the consumer. Through this function, it is possible to record important variations for the purpose of proper food preservation, signaling any abuse through color changes.
