Today more than ever, food preservation is a growing challenge, both for consumer needs and for the environment.
An innovative food packaging is active packaging, a type of packaging that not only physically protects the product, but actively intervenes in chemical and biological processes that can compromise freshness, preserving its quality through the use of special materials and advanced technologies.
The materials used in active food packaging can include antimicrobial substances, ethylene absorbers, oxygen absorbers and humidity regulators, each of which plays a specific role in maintaining the qualities of the product unaltered and prolonging its shelf life. This type of packaging is particularly advantageous for food products that require precise conditions to retain their flavor, freshness and nutritional value.
Innovative food packaging to reduce waste
In addition to improving product preservation, innovative food packaging has a significant impact on reducing food waste.
Sustainable nutrition is a crucial issue in today’s society and the ability of active packaging to extend the life of food helps reduce the amount of food that is discarded.
By reducing food waste, you also reduce greenhouse gas emissions associated with the production and decomposition of food waste, benefiting the environment and contributing to a sustainable future.
Thanks to the continuous evolution of food packaging technologies, the future promises increasingly efficient and environmentally friendly packaging, capable of meeting the needs of a constantly growing market.
New technologies and practical applications for food preservation
There are several active food packaging technologies that are revolutionizing the sector.
Oxygen absorbers are one of the most common tools, used to remove residual oxygen from packaging and prevent the growth of bacteria and mold. These absorbers are especially useful for products such as snacks, coffee and fresh meats, which are highly susceptible to oxidation.
Another innovation is represented by humidity regulators, which maintain an optimal humidity level inside the package. This is crucial for products such as dried fruit, cereals and baked goods, which can lose crispness and freshness if exposed to excessive moisture. Humidity regulators can be integrated into the packaging in the form of small packets or directly into the packaging materials.
Natural antimicrobials are another cutting-edge solution in active packaging. These compounds, derived from natural substances such as rosemary essential oil or chitosan, can be incorporated into packaging materials to inhibit the growth of harmful microorganisms. This technology is particularly useful for fresh products such as fruit and vegetables, which can be subject to microbial contamination.
Finally, ethylene absorbers are also used, which are essential for the preservation of fruit and vegetables, since this gas is responsible for over-ripening and rapid deterioration. By using ethylene absorbers integrated into the packaging, it is possible to significantly reduce the speed of maturation and, therefore, extend the product’s shelf life.
These innovative solutions demonstrate how it is possible to combine sustainability and functionality to offer consumers products that maintain high quality, fresh and safe.
Innovative food packaging by Cartotecnica Moreschini
Cartotecnica Moreschini, with its commitment to innovation and sustainability, has developed cutting-edge technologies capable of revolutionizing the sector.
In fact, the company recently introduced Carton Skinpackaging, an innovative packaging that uses recyclable and sustainable cardboard trays combined with a vacuum protective film that adheres perfectly to the product, almost like a “second skin”, reducing oxidation and prolonging the expiry date of foods.
