The raw material of the EVOH bottle is ethylene, which is the copolymer of vinyl alcohol. EVOH bottle toughness is good, can withstand deformation has a strong flexibility, especially external transparency, gloss, mechanical strength, scalability, wear resistance, cold resistance and surface strength are very excellent.
For food packaging, high-barrier material packaging is excellent in transparency, gloss, mechanical strength, stretchability, abrasion resistance, cold resistance and surface strength, and can completely replace glass and metal containers.
As early as more than 40 years ago, high-barrier technology began to be produced. The United States has used extruded polyethylene film laminated to metal foil as a barrier packaging material in the 1950s. It also includes processing technology on metal foil substrates. Since the foil material is very thin and has good barrier properties, it was thought that a high-barrier industry had been formed at that time.
