铝层牢度 Aluminum bonding |
薄膜与铝层的附着力较低， 剥离强度小于1.5N/15mm Weak adhesion and bonding between the film and the aluminum layer, and the peel off strength is less than 1.5N/15mm |
用于铝层牢度要求较低 的包装复合袋，通常需 要用三层复合结构 For usual packaging with weak bonding strength requirement. |
由于薄膜表面经过化学涂层处 理，薄膜与铝层的附着力高，剥 离强度可达4N/15mm以上 After chemical coated on PET film,it has higher adhesion and bonding between the film and the aluminum layer,and the peel off strength can reach 4N/15mm or more. |
用于包装要求高的结构，复合结构可以用 三层，且部分应用可以用二层结构代替三 层结构，从而降低成本。 For flexible packaging with higher requirements with laminated structure for three or four layers.In additional,two layer structure can replaced with 3-layer structure in some applications to reduce costs. |
|
铝层厚度 Aluminum Thickness |
常规铝层厚度，增加铝层 厚度，附着力会下降 Common aluminum layer thickness.The adhesion will decrease when increasing the thickness of the aluminum layer |
常规包装用途 Conventional packaging use |
由于铝层牢度高，可增加铝层厚 度而不会出现脱铝，延长内容物 的保质期，且保香性好 Because of higher bonding strength with aluminum layer, the thickness of the aluminum layer can be increased without dealuminization,the shelf life of the contents is extended,and the fragrance is good. |
适合用于奶粉、咖啡及零食包装等，能延长 内容物的保质期，且保香性好，结合复合工艺， 可用于水煮或蒸煮类型包装。 It is suitable for milk powder,coffee and snack packaging,etc.It can extend the shelf life of the contents and has good aroma retention.Combined with the composite process,it can be used for boiling or steam cooking type packaging. |
|
阻隔性 Barrier |
镀铝后具有较好阻隔性能 With a certain barrier property after metallization |
常规包装用途 Conventional packaging use |
可通过增加铝层厚度使其具有 更高的阻隔性 It has higher barrier properties by increasing the thickness of the aluminum layer |
可代替部分铝箔复合结构的包装 Can replace some aluminum foil composite structure packaging |
|
耐水性 Water resistance |
耐水性不高 Poor water resistance |
只能用于耐水性要求不 高的包装 Can only be used for packaging that does not require high water resistance |
耐水性好 Good water resistance |
选用VPET-JQ01,VPET-JQ17型号可用于 耐水性较高的场合，且针对液体包装进行 了改良VPET-JQ01&VPET-JQ17 can be used in high water resistance applications and it is improved for liquid packaging |
|
耐温性 Temperature resistance |
耐温性一般 Normal temperature resistance |
不能用于巴氏杀菌 Can not be used for pasteurization |
耐温性好 Good temperature resistance |
结合复合工艺， 可用于水煮或蒸煮类型包装。 it can be used in boiled/pasteurization and retorted cooked type packaging. |
