How to make cardboard more resistant

Staff Cart-One 19/06/2026 0

Cardboard is the key material for organizing shipments and keeping packages safe in the warehouse: this is why it must be resistant and of high quality.


How to make cardboard more resistant. A lack of robustness is often synonymous with logistical and sales issues, leading to inconvenience and a lack of quality when supporting fragile, delicate, and sometimes heavy goods. Let’s discover how to make cardboard more resistant.

Quality and Safety

Regardless of your goal, the cardboard box must always be made and chosen according to the product it will contain. This ensures shipping without logistical problems, avoiding falls, impacts, and crushing. The ideal choice is a double-wall cardboard model: stronger shipping boxes characterized by a higher grammage. Choosing unsuitable paper compositions means ending up with low-quality packaging and potentially damaged goods. Unexpected events, or even humidity, could damage the product inside the box.

Secondly, it is necessary to fill the content of the box without leaving empty spaces, preventing the goods from moving and, at the same time, supporting potential pressure from above or lateral impacts. To do this, use specific packaging materials such as:

  • Polystyrene
  • Foam rubber
  • Wrapping paper
  • Bubble wrap

The goal is to create a buffer between the box wall and the goods inside, perhaps adding internal structures to lock and immobilize them. This method guarantees greater resistance with a sort of internal skeleton: there are indeed honeycomb cardboard bases or cylinders (also called partitions) to be added to American boxes to secure very fragile objects like glass bottles. Another way to ensure greater safety is to print universal symbols to communicate the fragile nature of the content to handlers.

Closure and packaging

To make the cardboard even more resistant, in addition to tape, it is possible to use plastic straps to reinforce and keep the sides of the box compact, along with edge protectors to prevent the corners from being ruined: there are different shapes and models in rigid plastic, foam rubber, or cardboard. If, however, you need to ship bulky packages for long trips, you can opt for pallet packaging: standard wooden pallets are the perfect base to ensure that packages remain united on a single structure.

You can also add stretch film to this structure with a dedicated machine, enclosing the items into a single element, protecting them from both rain and shocks/movements due to the lightness of the package.

Mandatory non-financial statement also extended to SMEs
 On April 21st, 2021, the European Commission published a package of measures containing the proposal for a directive on corporate sustainability reporting: the Corporate Sustainability Reporting Directive (CSRD), which reviews and strengthens the current directive on non-financial reporting, aiming to expand the range of economic entities required to draft a non-financial statement. Indeed, from 2026, the NFS will also be mandatory for SMEs—which represent 99% of European Union companies—and must be provided in a digital format.   What the non-financial statement is and what information it must contain The non-financial statement and the sustainability report highlight the best practices that companies implement for sustainable growth. There are five minimum areas to address: Environmental impact: consumption of energy and water resources, distinguishing between those produced from renewable and non-renewable sources, and emissions of greenhouse gases and pollutants, with specific indication of carbon dioxide (CO2). Social impact: current and future impact in terms of health risk (and beyond) on the health and safety of individuals in society. Initiatives for the social and cultural development of the regions where the company operates. Worker protection: measures adopted to counter illegal hiring practices and child labor exploitation; improving the working environment while ensuring inclusion and gender equality. Protection of human rights: a list of all actions implemented to counter any type of human rights violation or discrimination. Anti-corruption: a list of all tools used to combat active corruption (which company executives might commit) and passive corruption (of which the company could be a victim). All included information must strictly comply with internationally recognized standards, first and foremost the GRI (Global Reporting Initiative). Who is required to file an NFS? Directive 254/14/EU (2014) and Legislative Decree 254/2016, which transposed it in Italy, mandate this requirement only for public interest entities with more than 500 employees that have exceeded specific size limits (total balance sheet: 20 million euros and total net sales and service revenues: 40 million euros). Limiting the requirement only to this category heavily restricted the directive's spread in Italy, considering that the Italian NFSs monitored by Consob in 2020 numbered only 204. Given the growing relevance of sustainability-related risks and because listed SMEs comprise a large portion of all listed companies in the Union, it is appropriate to extend the obligation to the following entities in order to ensure investor protection: listed companies with fewer than 500 employees, including SMEs (small and medium-sized enterprises) whose securities are traded on European regulated markets; large companies, even if unlisted. To achieve greater clarity regarding the presentation methods and required reporting frameworks for companies, the Commission relies on the Taxonomy, through which it aims to overcome the significant confusion surrounding reporting systems.  For whom is the NFS not mandatory? Micro-enterprises: currently and in the future, these will remain completely excluded from the reporting requirement. Unlisted SMEs: these companies can voluntarily prepare structured disclosures regarding sustainability based on standards aligned with their specific features. Corporate Social Responsibility and the expansion of the NFS At the core of the intent to extend non-financial reporting to small and medium-sized enterprises is the growing awareness that achieving success in international markets does not depend solely on good profit performances, but also on fulfilling social commitments. This is what is defined as Corporate Social Responsibility: namely, the set of actions implemented with the goal of actively addressing ethical and social impact issues and integrating them into business objectives.  Cart-One has always been committed to adopting innovative solutions for sustainable growth.

News on packaging regulations: towards safe, sustainable, and circular packaging
December 16, 2024, marks a decisive turning point for the packaging sector: the Council formally adopted the new regulation on packaging and packaging waste. This regulatory innovation, detailed in the PPWR special by ItaliaImballaggio, represents the latest evolution for a sector that, throughout its entire lifecycle, is moving towards more responsible and sustainable management.   News on packaging regulations: towards safe, sustainable, and circular packaging. In this article, we will explore the changes introduced, the implications for different application sectors, and the key role that efficient packaging can play in a circular economy strategy. Discover how these rules can transform your business and how Cart-One stands as a strategic partner in this transition.   Read also: “CE marking of machinery: what changes with the EU/2023/1230 regulation”   Safe, sustainable, and recyclable packaging: the new requirements The new regulation provides a series of ambitious targets for 2030 and 2040, aimed at promoting packaging that reduces environmental impact throughout its lifecycle. Among the main requirements are: Recycled content: by 2040, single-use plastic bottles must contain up to 65% recycled material, a key milestone to reduce dependence on virgin raw materials. Weight and volume reduction: the new rules require minimizing both the weight and volume of packaging, eliminating superfluous wrapping and optimizing design to reduce waste. Limitation of hazardous substances: substances of concern will also be reduced, for example by limiting the placement on the market of packaging in contact with food products that contains PFAS above certain thresholds. Labeling and information: requirements regarding labeling and marking aim to make sorting and proper disposal of packaging easier for the consumer, facilitating more conscious purchasing choices.   Restrictions on single-use plastic packaging The regulation introduces specific measures to limit the use of single-use plastic, particularly targeting: Pre-packaged fruit and vegetable products, especially if the weight is less than 1.5 kg. Food and beverages served in hotels, bars, and restaurants, with special attention to individual portions of condiments, sauces, cream, and sugar. Small single-use cosmetic and personal hygiene products typical of the hospitality sector (for example, shampoo bottles or lotions). Ultra-lightweight plastic bags, those often provided in markets for bulk food items. These restrictions are designed to encourage the adoption of alternative materials and drastically reduce the amount of single-use plastic that ends up in landfills.   Reuse targets and refill obligations The regulation sets new binding reuse targets for 2030 and indicative targets for 2040, diversified depending on the type of packaging. For example, for packaging intended for transport and sale, a binding target of 40% is planned, while for grouped packaging the target is set at 10%. Furthermore, businesses operating in the take-away sector will be obliged to offer customers the option of using personal containers, allowing them to be filled with food and beverages at no additional cost. This measure not only favors reuse but also encourages more sustainable consumption behaviors.   The packaging lifecycle and the new regulatory vision Despite progress in recycling, the EU still records high packaging waste production: in 2022, nearly 186.5 kg of waste were generated per inhabitant, with 36 kg from plastic alone. This scenario highlights how the amount of waste exceeds that of recycled material, making an update to the regulatory framework essential. The proposal to revise Directive 94/62/EC, now transformed into a regulation (PPWR), was conceived to promote a transition towards a circular economy and to steer Europe towards climate neutrality. The European Parliament and the Council agreed on their positions and, following a provisional agreement reached on March 4, 2024, the regulation will enter into force 18 months after its publication in the Official Journal of the EU.   The role of Cart-One in the transition towards innovative packaging In this evolving regulatory context, Cart-One confirms itself as a strategic partner for companies wishing to align with the new regulations and adopt cutting-edge packaging solutions. Our solutions offer: Safe and recyclable packaging: we design packaging that guarantees product protection and facilitates recycling, helping to reduce environmental impact.

The new regulation on packaging and waste represents an important regulatory evolution, aimed at transforming the packaging sector into a model of safety, sustainability, and circularity. With ambitious goals and restrictive measures, Europe is charting the course toward a future where every stage of the packaging lifecycle will be optimized to reduce waste and environmental impacts.   Cart-One stands as the ideal partner for companies wishing to make this leap in quality, offering innovative, safe packaging solutions compliant with the new regulations.

Packaging: paper is the fastest-growing food packaging material
The world of food packaging is undergoing a true revolution, driven by an extremely promising protagonist: paper. Packaging: paper is the fastest-growing food packaging material. As environmental concerns rise and consumers become increasingly aware of their choices, the food packaging industry is shifting toward sustainable and innovative solutions. In this context, paper emerges as the fastest-growing material, bringing a range of benefits that go far beyond environmental sustainability. Read also: “Reducing the environmental impact of packaging: what Europe mandates” Sustainability comes first One of the primary reasons paper is experiencing strong growth as a food packaging material is its eco-sustainability. Unlike traditional plastic packaging options, paper is biodegradable and compostable. This characteristic not only reduces negative environmental impacts but also meets the demands of a market increasingly focused on sustainability. Consumers actively seek products that reflect their ecological values, making paper an attractive option for brands wishing to stand out. Saying goodbye to plastic has become more and more important for modern consumers, and paper packaging is rapidly becoming the answer to this need. An increasing number of Italian families are embracing the idea of more sustainable packaging, with 65% in 2022 choosing a product specifically because of its eco-friendly packaging. Meanwhile, 19% gave up on buying a product due to its unsustainable packaging. Versatility and adaptability Paper offers high versatility, adapting to a wide range of packaging needs. From bags to boxes, and from tissue paper to folding containers, paper lends itself to multiple applications without compromising food quality or safety. Its flexibility allows packagers to create tailor-made solutions that meet the specific preservation and presentation needs of each product. According to research by Nomisma, the trend toward paper and cardboard is not just about beverages, but is gaining ground in every food sector, from fruit and vegetables to frozen foods. This reflects a significant cultural shift, with consumers placing higher value on packaging sustainability in every single part of their shopping cart. The power of recycling Italy has proven to be a powerhouse in recycling, generating 1 billion and 525 million euros in environmental benefits in 2021 through packaging recycling and recovery, according to the Conai Sustainability Report. This not only helps to save raw materials but also significantly reduces primary energy consumption and CO2 emissions. Italy, already a European leader in per capita packaging recycling, is in a privileged position to guide Europe toward a more sustainable future. Protection and freshness Contrary to common perception, paper is not just a sustainable choice, but also offers effective protection for food. Thanks to advancements in paper production technology, it is possible to develop solutions that maintain food freshness, protecting products from external factors such as light and moisture. This translates into longer shelf life for food products and a reduction in waste. Beyond practical aspects, paper also helps enhance the consumer experience. Its tactile and visual nature creates a unique sensory experience, evoking a sense of authenticity and connection with the product. Brands can leverage this feature to communicate their commitment to sustainable practices and create an emotional bond with consumers. Cart-One has always been a promoter and implementer of the circular economy—the produce-consume-regenerate-recover model—ensuring that our production waste becomes a paper reel and, ultimately, a box once again within our facilities. We firmly believe in protecting the environment, which is why we pay the utmost attention to saving raw materials and continuously improving our production processes, aimed at reducing our impacts on water, air, and soil.
