Packaging needs to protect the packaged contents from external influences, not react with the product, effectively present the product, and be simple, practical, and efficient. The demands for quality packaging are daily, while market needs are increasing, so for packaging to be of high quality, it must have the following coordinated packaging functions.

    • Marketing function

Due to high market competition, product packaging is gaining significant marketing function. Based on many studies showing how packaging plays a crucial role in attracting customer attention, more and more manufacturers are turning to environmentally friendly packaging to expedite the process of choosing between products and purchasing. A customer will always choose a product with better visual identity if it is similar in price or quality to other products. Packaging itself should influence the final purchasing decision. Potential customers need to be convinced that the product they intend to buy will meet their needs.

  • Logistic function

Packaging with good storage and transportation properties enables rational use of space. The packaging must be fully adapted to the goods because the higher the utilization of the packaging, the greater the utilization of storage and transportation space. The same applies to the relationship between sales and transport packaging and transport packaging to the storage and vehicle area. The logistic function plays a major role in protecting and facilitating processes:

  • Protecting the product from spillage (liquid, powder, or bulk content)

  • Protecting the product from environmental influences (moisture, temperature, ultraviolet radiation…)

  • Protecting the environment from packaging contents (if it is aggressive content)

  • Enabling and facilitating storage

  • Enabling and facilitating transportation

  • Enabling and facilitating handling

  • Protecting the product from theft

  • Providing information about packaging contents

    • Production function

The product must be protected throughout its entire cycle, from the moment of packaging, during transportation, storage, and sale, all the way to the final use by consumers. Packaging must ensure product protection from external influences, prevent spillage, and enable protection from possible deformations. Packaging on the market is mainly the result of the relationship between price, quality, and functionality, but it can only burden the price of the product to a certain extent. Goods are inherently resistant to various influences, but to a certain extent. All major loads and impacts on goods would have a negative result. Therefore, this function protects the product and enables the semi-finished product to become the final product. Some of the protections are: mechanical-physical protection, protection from oxygen, protection from moisture, protection from electromagnetic radiation, protection from microorganisms, protection from unfavorable temperatures…

    • Usage function

Packaging products in packaging that can be later reused for other purposes is the basis of the mentioned function. During and after the use of the product, this function comes to the fore, and it can facilitate the use of the product itself. How? Safety of handling, additional instructions on the packaging itself, possibility of reuse and recycling are examples of good usage function. Simplified mechanisms for opening and temporary closing significantly facilitate and promote the use function of packaging.

Paper finds wide application in packaging production, and it is characterized by a number of advantages such as mechanical strength, biodegradability, simple graphic processing, and relatively low cost. Cardboard is very easy to print, can be varnished, and can be bonded with other materials. They possess physical properties that enable further processing into flexible, semi-rigid, and rigid materials. They are used over a wide temperature range, as they can withstand very low temperatures as well as very high temperatures.
