This paper presents the results of research on selected mechanical and physical properties of polyethylene membranes containing 50% of the plant fraction obtained as waste from an edible oil press. The produced biomembranes were characterized by low tensile strength (2.02-4.28 MPa). The addition of plant material will not adversely affect the barrier properties such as water vapor permeability or the contact angle. Additionally, there was a discoloration of the characteristics affecting the shrinkage of the membrane. The presence of the plant component clearly lowered the shrinkage of the material. This research is important and provides valuable knowledge on the possibilities of using plant waste and the direction of the potential application of the materials produced with their use.
本文介绍了对含有50%来自食用油压榨废料的植物成分的聚乙烯膜的选定机械和物理性能的研究结果。所生产的生物膜的特点是拉伸强度低（2.02 - 4.28兆帕）。添加植物材料不会对诸如水蒸气渗透性或接触角等阻隔性能产生不利影响。此外，影响膜收缩的特性出现了变色。植物成分的存在明显降低了材料的收缩率。这项研究很重要，为利用植物废料的可能性以及使用这些废料生产的材料的潜在应用方向提供了有价值的知识。
