EHAp – BOPA Film with High Barrier Performance
EHAp is specially designed and produced in state-of-the-art LISIM simultaneous stretching process. Fresh-locking products have ultra-high barrier property, its composite application with food packaging materials can reduce the use of additives, extend the shelf life of food, lock freshness and preserve fragrance, and are key materials to promote healthy upgrading of foods and reduce food waste.
Compared with the EVOH co-extrusion film, EHA can achieve the same barrier effect to EVOH but less material due to the state-of-the-art LISIM simultaneous stretching process, and the thickness of EHA is only 15μm which is more cost-effective.
In addition, EHA’s outstanding printability can apply to various accurate registration. Compared with PVDC or other coating high barrier materials, EHA can achieve excellent tiny dots printability.

EHAp is a transparent, high-barrier functional film. It is resistant to 85℃ boiling or 105℃ hot filling, OTR lower than 2 CC/m2.d.atm. Comparing with the conventional BOPA films, the oxygen resistance performance of EHAp is ten times better, which makes it very suitable for the packaging that has strict requirement in gas barrier, such as pet food, compound condiments, pastries with short shelf life, cheese, kernels, fermentative dairy drinks and high-end balloons.
Bagging or after boiling warping
✔ Excessive heat sealing temperature or long time
✔ Structure of inner and outer layers’ tension control improper
✔ Inconsistent tension between the front and back of bags
