High-end leather packaging material safe, environmentally friendly, and has a good market prospect. It is an interesting technology to solve the intrinsic functionalization of skin collagen packaging materials. Nano-Hydroxyapatite (HA) precursors solution with a specific 1.67 calcium to phosphorus ratio (Ca/P) were infiltrated into the three-dimensional collagen network matrix (3DCM) in situ growth based on goat skin pretreated with glutaraldehyde and the HAG-3DCM was obtained. After compression, a transparent film HAG-3DCM-was formed. Structural and functional characterization showed that the HAG-3DCM-CM film has good comprehensive performance, such as the tensile strength increased to 67 mPa from 28 mPa, the bending resistance increased from 5 cycles to 50 cycles and the swelling degree from 55% to 12%. HA disperses and fixes the three-dimensional collagen network matrix (3DCM) fibers, improves its stability against humidity and heat, and the thermal conductivity changed from 0.72 W/(K•m) to 0.65 W/(K•m). HAG-3DCM has a relatively high limiting oxygen index of 26.5%. This study demonstrates a new approach for preparing animal skin packaging materials with new application value.

高档皮革包装材料安全、环保，具有良好的市场前景。解决皮肤胶原蛋白包装材料的内在功能化是一项有趣的技术。将具有特定 1.67 钙磷比 (Ca/P) 的纳米羟基磷灰石 (HA) 前体溶液渗入基于用戊二醛预处理的山羊皮原位生长的三维胶原网络基质 (3DCM) 中，并制备了 HAG-3DCM。获得。压缩后，形成透明薄膜HAG-3DCM-。结构和功能表征表明，HAG-3DCM-CM薄膜具有良好的综合性能，抗拉强度从28 mPa提高到67 mPa，抗弯强度从5个循环提高到50个循环，溶胀度从55%提高到12 %。HA分散并固定三维胶原网络基质（3DCM）纤维，提高其对湿热的稳定性，热导率从0.72 W/(K•m)变为0.65 W/(K•m)。HAG-3DCM 的极限氧指数相对较高，为 26.5%。本研究展示了一种制备具有新应用价值的动物皮包装材料的新方法。
