Non-PVC Film Soft Bag Filling Line

BRIEF INTRODUCTION

The non-PVC soft bag filling production line adopts internationally advanced technology and is specifically designed for the production of infusion products, meeting the requirements of both domestic and international markets. The line uses non-PVC multilayer co-extruded soft bags, which are non-toxic and offer excellent liquid compatibility and superior water vapor barrier properties. The bags can withstand high-temperature sterilization at 121 °C and also exhibit good low-temperature resistance, making them easy to transport and recycle. This solution represents an ideal, environmentally friendly packaging option for infusion products.
