塑料薄膜的粘接力的大小即為熱封的強(qiáng)度

　　The size of the plastic stick relay is the strength of the heat sealing

　　我們常用熱封強(qiáng)度來表代封口性能,熱封強(qiáng)度是熱封樣條在熱封強(qiáng)度檢測(cè)時(shí)的最大值.熱封強(qiáng)度是一個(gè)重要的指標(biāo),它表明了封口所能承受內(nèi)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(qiáng)度很小,無法承受運(yùn)輸?shù)冗^程中內(nèi)容物的重量,封口就會(huì)被破壞.但這只是描述了封口性能的靜態(tài)要求,在實(shí)際使用過程中,包裝封口所要承擔(dān)的大部分都是動(dòng)態(tài)的負(fù)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(gè)表現(xiàn)靜態(tài)特性的熱封強(qiáng)度是不能完全代表封口特性的,因而提出另一個(gè)指標(biāo)”封口破壞能”,與封口強(qiáng)度不同的是,封口破壞能記錄的是破壞一個(gè)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(qiáng)度有關(guān)外,還與復(fù)合材料本身的柔軟性,可延伸性等有關(guān),實(shí)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(nèi)容物從靜態(tài)來看,所需要的封口強(qiáng)度一樣,但從動(dòng)態(tài)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.
