The problem of the interaction of polymer packaging with CBD is reported in the literature very little. Along with this, due to the complication of the component of both systems, following the contact, physical and biochemical processes of interaction take place, especially during the long storage of CBD products in CBD display box.
That is why the main physico-chemical methods of polymers are used to master this problem, especially finding the parameters of mass transport and thermodynamics. The action of media, the main component, as a rule being water and fat, consists in their penetration in the volume of the polymer material and the weakening of the bonds between the macromolecules of the polymer mold.
- The process of transporting the mass of the low molecular components of CBD is performed as the diffusion-activated mechanism. The transport of the low molecular weight and algometric bonds in polymers depends on the structure and composition of the polymer and the environment, the polarity, the hardness of the polymer chains, the existence in polymers of the free meshes. Polymeric (stabilizers, polifiers), the product changes its qualities. At the same time, the loss of the exploitation qualities of the material can be observed.
Choice of Packaging Material
The attachment to each CBD and packaging system is individual. The choice of CBD packaging material is made according to the composition of the packaged product, the conditions and term of storage, and requires a qualified and skilled hanging.
The high content of fats (e.g.: up to 10% in chips) and the necessary vitamins keep efficient and important the action of air humidity, and even often light. Processes with specific odors must be packaged in packages that do not allow the penetration of foreign flavors. Knowing the biochemical composition of the product, it is possible to formulate the basic requirements, without packaging materials and to choose the packaging method.
It is necessary to take into account, and the fact that in the storage process complicated biochemical processes take place in the product, and even at the same time the interaction between the product and the packaging on the one hand, packaging and environment on the other.
Therefore, when choosing the packaging for one CBD product or another, it is necessary to take into account the properties of the packaging material that depend on their vulnerability depending on different environments:
- The light
- Scents
The characteristic of the vulnerability of the packaging material in accordance with a sensitivity of the CBD products in the complex of the factors of the external environment, allow us to determine after the calculations the term of keeping the product in the packaging. However, the system of interaction of the external environment with the CBD product can be analyzed by containing the components of the external environment, the internal environment, the CBD product
In case the CBD product is in contact with the environment inside the package, the content of which depends on the storage conditions, and on the external environment with which its interaction is determined by the qualities of the packaging material. The optimal conditions for storing the product can be obtained by creating a regular or modified thick environment inside the package, or by creating a vacuum.
The choice of packaging is determined according to several criteria:
- The biochemical content of the packaged product;
- Storage conditions;
- The properties of the packaging material;
- Kinetic changes in product and packaging quality.
One of the basic requirements for packaging materials that are in direct contact with CBD is physiological purity. By physiological purity is meant the inability to pass in the CBD product from the packaging material of foreign elements, which can translate changes in color or taste of the product and which act negatively on the body’s activity. These harmful foreign elements can be emulsifiers, dyes and other auxiliary components.
In each particular case, the use of the polymeric material for the packaging of the CBD product is obtained by the approval of the special body of the Ministry of Health in accordance with the approval in each state of the sanitary-hygienic laws.
