EVOH High Barrier Thermoforming Film

Application

In practical applications, the EVOH High Barrier Thermoforming Film produced by Nacheng can be adapted to various shaped packaging items, whether it is regular boxed products or irregular bagged items, they can all be tightly wrapped through flexible stretching, effectively reducing the loosening or damage of packaging.

Good barrier properties can mitigate the impact of external adverse factors on internal products, helping to maintain the quality stability of products during storage and transportation, it has a wide range of application Spaces in industries with high requirements for packaging protection, such as food, medicine, and electronics.

The EVOH High Barrier Thermoforming Film also maintains the neatness and transparency of the film material in appearance, after wrapping, the internal product shape can be clearly presented without affecting the visual display effect of the product, taking into account both protective function and appearance presentation.

What is EVOH

EVOH is a polymer material with excellent barrier properties, and its full name is ethylene-vinyl alcohol copolymer, it is a copolymer formed by combining ethylene and vinyl alcohol, two monomers, through a specific polymerization process. This special molecular structure endows it with unique performance advantages.

In terms of characteristics, the most prominent feature of EVOH is its outstanding barrier property, especially in blocking gases such as oxygen and carbon dioxide, effectively preventing these gases from penetrating the material, this is also the core reason why it is widely used in high-barrier packaging fields. EVOH also has excellent chemical stability, when in contact with most common chemical substances, it is not prone to reactions and can maintain the stability of its own performance.
