| 中文摘要: |
| 目的 坚果仁铝塑复合膜包装易出现袋体泄漏、 复合膜剥离分层、 热封不良等问题， 导致产品在保质期内变质， 需监测坚果仁包装材料的关键性能并熟知改进工艺， 保证优质包装材料的选用。方法 以3种不同材质及厚度的坚果仁铝塑复合膜包装为例， 测试并对比分析3种包装材料的揉搓前后的氧气透过率、 剥离强度、 耐热性、 热封强度、 密封性能等关键参数。结果 3种包装材料中， 1#样品各方面性能均较优， 2#样品仅在耐揉搓性方面稍差， 3#样品各方面性能均较差。结论 坚果制品企业在选用铝塑复合膜包装材料时， 应在充分考虑内容物的特性、 保质期、 存储条件等因素的基础上， 注重包装材料厚度、 各层膜质量及热封工艺， 并及时监控包装材料性能， 从而筛选出阻氧性、 物理机械强度及密封性能较好的包装材料。 |
| 英文摘要: |
| Some problems may happen to the aluminum foil packages for nuts such as package leakage, delaminaion of composite film or low sealing performance, which may cause quality problems of the products within the shelf life. Therefore, it is necessary to monitor the key properties of the packaging materials and improve the manufacturing craft to ensure the quality of the packages for nuts. Aluminum-foil packages made of three different materials with different thickness were used in the comparative tests. The oxygen permeability, peeling strength, high temperature resistance, heat sealing strength and sealing performance were compared after flex durability tests of the three test specimens. The key properties of Specimen No.1 were all good, Specimen No.2 showed poor flex durability while Specimen No.3 was of bad quality. The nuts manufacturers should take the product features, shelf life, storage conditions and other factors into consideration when selecting aluminum-foil packaging materials. The thickness, quality of composite layers and heat sealing technique should be emphasized and the performance of the packages should be monitored so that the proper packaging materials with good oxygen barrier property, physical and mechanical strength as well as sealing performance can be used. |
