First example of the use of 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methyl-morpholinium chloride (DMTMM) as cross-linking agent for the development of carboxymethyl cellulose (CMC) films for food packaging is reported. Influence of different wt % of DMTMM and glycerol on the physical-mechanical properties of CMC films was investigated. The presence of DMTMM effectively improved moisture uptake, moisture content, water vapour permeability, water solubility of the films, oil resistance together with good biodegradability. Best compromise between high water resistance, vapour permeability and mechanical properties was accomplished with 5 wt % DMTMM and 50 wt % glycerol giving tensile strength and elongation at break of 52.25 ± 4.33 and 37.32 ± 2.04 respectively. DSC, TGA and SEM analysis further confirmed CMC cross-linking by DMTMM. All films prepared showed low opacity and high transparencies. Therefore, data reported show that DMTMM can efficiently cross-link CMC to produce films for food packaging.

使用4-（4,6-二甲氧基-1,3,5-三嗪-2-基）-4-甲基-吗啉氯化物（DMTMM）作为交联剂开发羧甲基纤维素（CMC）的第一个例子）报道了用于食品包装的薄膜。研究了不同重量百分比的DMMTM和甘油对CMC薄膜物理力学性能的影响。DMTMM的存在有效地改善了水分吸收，水分含量，水蒸气渗透性，薄膜的水溶性，耐油性以及良好的生物降解性。高耐水性，水蒸气渗透性和机械性能之间的最佳折衷是通过使用5 wt％的DMTMM和50 wt％的甘油实现的，拉伸强度和断裂伸长率分别为52.25±4.33和37.32±2.04。DSC，TGA和SEM分析进一步证实了DMTMM的CMC交联。制备的所有膜均显示出低不透明度和高透明性。因此，报告的数据表明DMTMM可以有效地使CMC交联以生产用于食品包装的薄膜。
