Russia’s attack on Ukraine has become a dramatic fact. The dynamically changing situation does not allow us to remain indifferent to the aggression experienced by our neighbors. At the moment, in order to become as unified as possible with Ukraine, we collect the most necessary things and organize accommodation. As of today, we have managed to collect 14 pallets of the most necessary articles that have already left for Ukraine. The fundraiser continues and will continue as long as support is needed.
Take care of yourself.

oxygen and carbon dioxide). Barrier is a parameter that determines the permeability of gases through a given material. The appropriate level of foil barrier ensures that the packaging will be suitable for storing, among others food products, thus extending their shelf life. The limited migration of gases into the interior and from the packaging guarantees the desired organoleptic qualities of the stored products. The limited access of oxygen delays the aging process and effectively blocks the growth of microorganisms in the product. The current technological possibilities allow for a wide range of modifications in the composition and structure of EVOH foil, towards a significant increase in the barrier to gases, strength and color of the foil itself.
characterized by a barrier to light radiation (especially UV). This is important when the stored product is particularly prone to aging under the influence of UV and requires additional protection against light. 
operations (treatment by the target customer, storage conditions, etc.) significantly affect the durability and functionality of the packaging. Years of experience and tests carried out in laboratory conditions (transport tests and simulations with the use of vibration methods) have proved significant differences in the durability of packaging made of EVOH film compared to Met-PET film. In particular, we are talking about the number of generated microdamages, which significantly affect the deterioration of foil mechanics (foil strength) and worsen the barrier properties of the package. One of the methods of testing the susceptibility of film and entire packaging to durability throughout the distribution process is the Gelbo method. It consists in cyclic twisting a sheet of foil through an angle of 460 °. The foil sheets treated in this way are then checked for the number of microdamages or the level of oxygen permeability (OTR). Below we present the results of our tests carried out on EVOH film and Met-PET film. The samples were subjected to 900 cycles and examined for the number of microdamages.
there is a growing awareness of users about the fate of used packaging, the method of recovering secondary raw materials or potential environmental fees (e.g. the fee for extended producer responsibility). Based on the recommendations of the RecyClass group, we can conclude that flexible packaging made of Met-PET film will be classified as low compatibility (D-E-F) due to the difficult process of post treatment towards obtaining secondary raw materials. At the same time, packaging based on EVOH film (classified as limited capatibility C-D), can in most cases be further processed to recover, among others, polyethylene (LDPE).
