What is EVOH? How could it do with PET?

EV0H, a new type of high barrier material, its gas barrier than PE (polyethylene), PP (polypropylene) 10,000 times higher than the currently used barrier material PVDC (polyvinylidene chloride) more than tens of times, is the highest barrier plastic found in the world. EVOH as a packaging material, in addition to oxygen, carbon dioxide and other gases have excellent barrier and odor barrier, but also EVOH is non-toxic, non-irritating and environmentally friendly, so it can be used in food and pharmaceutical packaging. However, the cost and price of EVOH is high and the impact resistance is poor, thus limiting its use to some extent.

It is found that EVOH can be mixed with PE, PA (polyamide), PP, LLDPE (linear low density polyethylene) and other packaging materials to achieve complementary advantages and form composites with better barrier effect, but the performance of these composites in various aspects, such as impact resistance, transparency and impermeability, is still unsatisfactory.

Its good impact strength, good barrier effect, good transparency, non-toxic, environmental protection, can be widely used in fresh fruits, vegetables and meat and other food and pharmaceutical packaging.
