Abstract

Abstract The dominance of plastics in the packaging market is due to their low weight and thickness, which save transportation costs. However, their non-biodegradability poses a significant threat to the environment. Paper, on the other hand, is considered as a safer alternative due to its natural composition and biodegradability. The porous structure of paper limits its application in packaging, and its poor water resistance further restricts its use in humid environments. Therefore, lamination is a method useful tool to improve the barrier properties of paper. Additionally, the researchers are focusing on developing biodegradable and water-based coatings with anti-fat properties as a green alternative to plastic packaging. The impact of a new grease-resistant coating composed of starch, gelatin and sodium alginate on the mechanical properties of paper was investigated through tensile, tearing, and bursting strength tests. The results showed significant improvements in the mechanical properties of the coated paper sheets. Furthermore, the biodegradability test indicated that the paper samples coated with the new composition showed a 50% weight loss after one week of incubation in the soil, and after three weeks, they exhibited 100% weight loss, demonstrating their outstanding biodegradability.

基于生物聚合物的纸涂层，具有提高的油脂电阻率、生物降解性和机械性能

摘要塑料在包装市场上的主导地位是因为它们的重量和厚度都很低，节省了运输成本。然而，它们的不可生物降解性对环境构成了重大威胁。另一方面，纸张由于其天然成分和生物降解性，被认为是一种更安全的替代品。纸张的多孔结构限制了其在包装中的应用，而其较差的耐水性进一步限制了它在潮湿环境中的使用。因此，叠层是提高纸张阻隔性能的一种有效方法。此外，研究人员正专注于开发具有抗脂肪性能的可生物降解和水性涂料，作为塑料包装的绿色替代品。通过拉伸、撕裂和爆裂强度测试，研究了由淀粉、明胶和海藻酸钠组成的新型耐油脂涂层对纸张力学性能的影响。结果表明，涂层纸张的机械性能有了显著改善。此外，生物降解性测试表明，涂有新组合物的纸样品在土壤中孵育一周后，重量减轻了50%，三周后，它们的重量减轻了100%，证明了它们卓越的生物降解性。
