In order to obtain innovative, high-quality biodegradable packaging, double-layer films based on furcellaran and gelatin, enriched with plant extracts were created. The films were assessed considering their potential utility, applications and environmental impact. The mechanical properties over a period of nine months were studied and it was noted that the passing of time had a beneficial effect on these parameters. The antioxidant properties was also examined, with the highest results obtained using the DPPH and metal chelating activity methods for GE (76.64 % and 9.85 % respectively), while this film showed the lowest FRAP value (5.99 %) compared to the highest obtained for DTE (52.62 %). For the first time, the possibility of using the double-layer active FUR/GEL film as packaging for salad-dressing was evaluated, but no improvement in parameters was observed regardless of the extract used. The environmental impact analysis showed the ability to completely decomposed in vermicompost within several days.
为了获得创新的、高质量的可生物降解包装，我们开发了基于蕨麻纤维和明胶的双层薄膜，并添加了植物提取物。我们评估了这些薄膜的潜在用途、应用和环境影响。研究了它们在九个月内的机械性能，结果表明时间的推移对这些参数有有益的影响。我们还研究了抗氧化性能，使用 DPPH 和金属螯合活性方法，GE 获得的最高结果分别为 76.64%和 9.85%，而 FRAP 值（5.99%）最低，与 DTE（52.62%）的最高值相比。首次评估了双层活性 FUR/GEL 薄膜作为沙拉酱包装的可能性，但无论使用哪种提取物，参数都没有得到改善。环境影响分析表明，该薄膜能够在数天内在堆肥中完全分解。
