In order to utilize the properties of multiple polymers at the same time, multi-layer structures are usually used in packaging. The high-barrier stretch film process is to form a multi-layer structure film from multiple different polymers in the same process. It can combine the chemical and The advantages of physical properties are combined to meet and solve the special needs of packaging materials in the food, medicine and other industrial fields, especially in the film technology of PA.EVOH as the barrier material.
The high-barrier stretch film packaging uses physical processing technology and adopts internationally recognized environmentally friendly materials. It is different from most currently used composite packaging. It does not use adhesives, so it does not contain heavy metals and no residual solvents , Is a green and safe food packaging.
