Introducción del producto
Nuestro Blue Plastic Bag-in-Box with Clear Tube is a reliable, hygienic packaging solution for milk and liquid dairy products.
The outer bag is made from high-strength blue polyethylene (Orina), offering excellent puncture resistance and a distinctive brand appearance. el incorporado transparent dispensing hose (clear PVC or silicone) lets operators and consumers see the liquid flow – making dispensing easy and spill‑free.
This bag-in-box system works with both aseptic and pasteurized filling. It keeps milk fresh without refrigeration during short-term logistics (or with cold chain for fresh milk). As liquid is dispensed, the bag collapses, preventing air backflow and oxidation.
Perfecto para: cafeterias, school milk programs, hoteles, and food service.
