EVOH F171B Resin Overview | High-Barrier Plastic for Food
Product Struction
What is Kuraray EVAL™ EVOH F171B ?
EVOH F171B (ethylene-alcohol copolymer) is produced by Kuraray Co., Ltd. The developed high-performance resin is specially designed for packaging applications that require excellent gas barrier performance and is widely used in multi-layer food packaging, pharmaceutical containers and industrial packaging films. As global demand for health and safety escalates, EVOH F171B is transforming itself from an ‘optional material’ to a ‘key barrier technology,’ becoming the invisible guardian of high-end fresh packaging, aseptic medical containers, and smart films.
Why Choose EVOH F171B?
1.Extreme gas barrier to protect product quality
EVOH F171B has a very low oxygen transmittance (OTR), which can effectively delay the oxidation reaction of food and drugs, greatly extending the shelf life. This makes it perform well in vacuum packaging, modified atmosphere packaging and aseptic pharmaceutical packaging, reducing waste and enhancing product value.
2.Outstanding structural strength ensures stable packaging
Its tensile strength is as high as 34 MPa and its flexural modulus is 4800 MPa, which means it has good supporting capacity and impact resistance in multi-layer packaging and is not easy to be damaged during transportation.
3.Stable Processing Performance and Adaptability to Various Processes
EVOH F171B has a melt index of 1.6 cm³/10min (190°C), which makes it suitable for a wide range of processes such as blow moulding, co-extrusion and injection moulding, as well as for co-extruding and moulding with other materials, such as PET, PE, PP, and so on.
[ Real customer feedback cases ]
Ⅰ. Food Enterprise A: "EVOH F171B has extended the preservation time of our high-end meat packaging from 10 days to 30 days, significantly reducing returns and losses."
Ⅱ.Pharmaceutical Company B: "By applying this material in sterile medicine bottles, we have successfully replaced PVC with environmentally friendly barrier materials, and the manufacturing process has also become more efficient."
Scalability and Innovative Applications
1.New Paths for Sustainable Packaging development
With the increasingly strict environmental protection policies, EVOH F171B can be combined with degradable resins (such as PLA, bio-based PE), taking into account both barrier properties and environmental friendliness. It can make positive contributions in reducing resource waste and improving material recovery rates, meeting the sustainable development needs of enterprises.
2.New trends in intelligent packaging
EVOH F171B can be used as a barrier substrate for smart labels or gas sensing materials to develop smart packaging with functions such as preservation prompts and gas detection, such as integrating gas sensors or RFID tags, etc. It can monitor food quality in real time and provide more safety guarantees for consumers.
3.New applications in the medical field
EVOH F171B's molecular barrier is like an ‘invisible armour’, which not only isolates more than 99% of oxygen penetration, but is also perfectly compatible with active pharmaceutical ingredients, making it an ideal choice for inhalers and cold-chain diagnostic reagent bottles. In the future, EVOH F171B can be combined with micro-sensor technology to achieve intelligent detection and tracking of drug packaging, thereby improving the stability, traceability of drugs and the medication safety of patients.
[ Recommended combinations of materials (based on the required scenarios) ]
Ⅰ. High transparency requirement: It can be combined with PET to enhance the visual effect.
Ⅱ. Heat resistance requirement: It can be combined with PP or PPS materials to enhance high-temperature performance.
Ⅲ. Strong barrier and pressure resistance: When used in combination with multi-layer PE, it is suitable for liquid packaging or heavy-duty transportation packaging.
