Selection of glue quantity on daily chemical packaging bag
The standard glue loading range is 2.8-3.2gsm. Too much glue loading has no significance on peel strength, but increases drying load. For the composite equipment with insufficient drying capacity, it increases the probability of delamination and bag breaking after cooking.
When testing the amount of glue, pay special attention to the moisture content of nylon film before and after drying, which affects the accuracy of glue content detection!
In the production of boiled bags, manufacturers should not only pay attention to the amount of glue, but also pay attention to the micro uniformity of adhesive coating. The parameters of wire roller will directly affect the micro uniformity of adhesive coating.
