In the process of making machine-made bags,the contents will leak or deteriorate due to incomplate heat sealing.For this kind of situation,it is mainly caused by the poor popularity of anti fouling heat sealing of the film,or the improper resin used in the inner seal.
Don't worry about this.Mingfeng machinery has brought you countermeasures to solve this kind of situation.Let's learn about it together.
Countermeasures:adopt the film with good anti pollution heat sealing property.Generally speaking,LDPE has medium anti pollution heat sealing property,EVA has good anti pollution heat sealing property when the VA content is large,LDPE also has good anti pollution heat sealing property,and ionic resin and metallocene polymer have excellent anti pollution heat sealing property.
