Question:

FFS plastic film bags are injection types?

FFS plastic film bags are injection type?

Answer:

Tube film (blown film process) has become the best production method of FFS bag film products. FFS bag blown film technology is divided into single layer extrusion and multi layer extrusion technology according to its product form. Their production principle is basically the same, mainly equipment is different.
Mainly uses a large single screw extruder and single monolayer extruder head configuration, three layer co extrusion equipment is divided into three layers of laminated film blowing head of three smaller extruder and configuration can be automatically adjusted, other devices on the same.
The continuous production of "forming filling sealing (Form Fill-Seal, referred to as FFS)" bag blown film products, is a domestic heavy packaging film technology developed in recent years, mainly used for automatic packaging line of large polyethylene, polypropylene and other synthetic resin products.
FFS plastic film bags are not injection molding, blow molding.
