塑料薄膜的粘接力的大小即為熱封的強度
The size of the plastic stick relay is the strength of the heat sealing
我們常用熱封強度來表代封口性能,熱封強度是熱封樣條在熱封強度檢測時的最大值.熱封強度是一個重要的指標,它表明了封口所能承受內容物的重量.紙袋廠家http://www.jnqcsl.com/
We often use heat seal strength to table generation of sealing performance, heat sealing strength is heat sealing spline maximum when heat sealing strength testing. Heat sealing strength is an important indicator, it shows that the sealing can bear the weight of the contents.
如果熱封強度很小,無法承受運輸等過程中內容物的重量,封口就會被破壞.但這只是描述了封口性能的靜態要求,在實際使用過程中,包裝封口所要承擔的大部分都是動態的負荷.
If heat sealing strength is very small, can't bear the weight of the contents in the process of transportation, the seal will be destroyed. But it only describes the static sealing performance requirements, in the process of actual use, take away most of the packing seal is dynamic load.
只用一個表現靜態特性的熱封強度是不能完全代表封口特性的,因而提出另一個指標”封口破壞能”,與封口強度不同的是,封口破壞能記錄的是破壞一個封口所需要的能量.
Only a static performance characteristics of heat sealing strength is not fully represent the sealing characteristics, thus put forward another indicator "sealing can damage", and the sealing strength, seal damage can record the energy needed to break a seal.
封口破壞能反映了封口的抗沖擊性能,其除了與熱封強度有關外,還與復合材料本身的柔軟性,可延伸性等有關,實際上是反映了封口的韌性.
Seal damage can reflect the sealing of shock resistance, it besides related to the intensity of the heat sealing, also with the softness of composite material itself, extendability and so on, is actually reflects the sealing of toughness.
同一重量的內容物從靜態來看,所需要的封口強度一樣,但從動態來看,包裝1000g的餃子和包裝1000g的湯圓所需要的封口性能是有很大差別的.
The contents of the same weight from the point of static, the required sealing strength, but from the point of dynamic, packing 1000 g of dumplings and 1000 g of tangyuan sealing performance is needed to have very big difference.
