Description

一种可降解的食品塑料包装袋
技术领域
本发明涉及食品包装技术领域，尤其涉及一种可降解的食品塑料包装袋。
背景技术
随着经济发展和人民生活水平的提高，人们对食品安全和食品要求逐渐提高，因此食品包装质量成为了人们关注的重点，人们已不仅仅关注包装袋的使用安全，更开始注重包装袋对食品质量的保护。
食品塑料包装袋普遍具有不可生物降解和非完全可再生利用的特点，而基于环境可持续发展、资源可再生利用的观念的加深，可降解再生的食品包装袋受到了越来越广泛的关注。
发明内容
本发明旨在满足食品包装袋的可降解要求，而提供一种利于环境可持续发展、抗菌保鲜的可降解的食品塑料包装袋。
本发明为实现上述目的，采用以下技术方案：一种可降解的食品塑料包装袋，包括以下原料，木薯淀粉，碳酸钙，聚乙烯醇，壳聚糖，抗氧剂，润滑剂，十八酸丙三醇酯，醋酸，甘油，戊二醛，KH792。
优选地：包括以下原料，
优选地：包括以下原料，
优选地：所述抗氧剂为抗氧剂BHT。
优选地：所述润滑剂为硬脂酸锌。
本发明的有益效果是：本发明中聚乙烯醇塑料薄膜具有良好的耐油性、阻气性，具有优异的透明性和光泽，且在一定条件下具备水溶性和可生物降解性；木薯淀粉渗透力强、成膜性好、灰分含量低；壳聚糖作为天然抗菌剂，具有良好的生物相容性及可降解性，可再生，无毒副作用，抗菌防腐能力较强。本发明的食品包装袋既能实现食品的保鲜、保质保存，又能实现食品防菌，且使用完毕后可进行生物降解，实现了环境的可持续发展、资源的可再生利用。
具体实施方式
下面结合实施例对本发明作进一步说明：
本发明可降解的食品塑料包装袋，包括以下原料，木薯淀粉，碳酸钙，聚乙烯醇，壳聚糖，抗氧剂，润滑剂，十八酸丙三醇酯，醋酸，甘油，戊二醛，KH792。
其中本发明可降解的食品塑料包装袋包括以下原料，
所述抗氧剂为抗氧剂BHT。
所述润滑剂为硬脂酸锌。
实施例1，
本发明包括以下原料，
所述抗氧剂为抗氧剂BHT。
所述润滑剂为硬脂酸锌。
实施例2，
本发明包括以下原料，
所述抗氧剂为抗氧剂168。
所述润滑剂为硬脂酸锌。
实施例3，
其中包括以下原料，
所述抗氧剂为抗氧剂1010。
所述润滑剂为石蜡。
实施例4，
其中包括以下原料，
所述抗氧剂为抗氧剂BHT。
所述润滑剂为聚乙烯蜡。
本发明中聚乙烯醇塑料薄膜具有良好的耐油性、阻气性，具有优异的透明性和光泽，且在一定条件下具备水溶性和可生物降解性。
淀粉作为一种天然高分子多糖，资源丰富，有很好的生物相容性和可降解性，且其成本低、透明度高，其中木薯淀粉渗透力强、成膜性好、灰分含量低，因此相较于其他淀粉具有一定的使用优势，但是淀粉成膜的机械性能较差，阻湿性能也不好，因此一般将其与其他材料配合使用以制成综合性能良好的食品包装袋。
壳聚糖又称脱乙酰甲壳素，是由自然界广泛存在的几丁质经过脱乙酰作用得到的，作为天然抗菌剂，其具有良好的生物相容性及可降解性，可再生，无毒副作用，抗菌防腐能力较强。
上述三种材料制造复合制备出一种抗菌保鲜且可生物降解的食品包装塑料袋。
本发明中优选的抗氧剂选用抗氧剂BHT，润滑剂选用硬脂酸锌，改性剂选用KH792，分散剂选用十八酸丙三醇酯。
上面对本发明进行了示例性描述，显然本发明具体实现并不受上述方式的限制，只要采用了本发明的方法构思和技术方案进行的各种改进，或未经改进直接应用于其它场合的，均在本发明的保护范围之内。
