Introducing fillers into polymeric materials is one of the methods of modifying the properties
or reducing the costs of polymeric materials. Thanks to their use, it is possible to obtain new …

One of the methods of changing the mechanical properties of polymeric materials is by the
creation of composites with various substances whose task is to strengthen and fill them …

As part of the work, new polymer materials were used in 3D printing, which can be used in
three technologies depending on the apparatus used: Fused Filament Fabrication (FFF) …

This paper presents the results of tests on PLA-based composite materials produced by
mixing a base polymer (PLA-polylactide) with PLA fiber. The main aim was to obtain …

The ways of using coffee grounds as fillers for biodegradable polymer material and dishes
from it is shown. Research of chemical, physical, mechanical and operational properties of …

Two types of cellulose fibers (10–40% by mass) were mixed with polylactide by an open-
ended spiral-shaped injection molding. Tensile strength, impact strength and hardness of …

Packaging is one of the primary factors that influence the consumer's decision to purchase a
product. Competent packaging design makes it possible to distinguish the product from …
