On the other hand,because the vacuum seal bag is too large,it will be more extra space in it,when you open the mouth of the bag,there is more space for outside air,which is not beneficial for the inside product.

influenceAnd another case is that,what if the vacuum seal bag is too small,the affect is evident.If the vacuum seal bag is small,it can not totally pack the product,which means that it can not play its role in protection.In addition,vacuum seal bag which is small may cause problems during the vacuum process.
