EVOH RESIN

EVOH Resin (Ethylene-Vinyl Alcohol Copolymer) is an engineering plastic with outstanding gas barrier properties, combining the processability of polyethylene and the barrier performance of polyvinyl alcohol. The product delivers high efficiency in food packaging, pharmaceuticals, and various industrial applications.

Applications:

Used in food packaging to block oxygen, preserve flavor, and extend shelf life.
Applied in pharmaceutical and cosmetic packaging to prevent evaporation and product degradation.
Utilized in the production of automotive fuel tanks, oil pipes, gas pipes, and construction materials due to its durability and structural stability.
Used in the manufacturing of plastic bottles, containers, multilayer packaging, and medical tubing.

Packaging: Multi-layer aluminum vacuum-sealed bags.

Technical Specifications:

Color: White, transparent, or semi-transparent
Density: 1.10 – 1.22 g/cm³
Melting point: 158 – 189°C
Water solubility: Insoluble
Thermal stability: > 300°C
Oxygen transmission rate (OTR): 0.3 – 0.7 cm³·20µm/m²·day·atm
Melt flow index: 1.5 – 2.5 g/10min

Supplier: SINOPEC SVW

Description

EVOH resin combines the characteristics of polyethylene (easy processability) and polyvinyl alcohol (excellent gas barrier), significantly improving gas resistance, oil resistance, solvent resistance, and transparency.

The product meets strict safety standards, free from heavy metals and toxic substances, and releases only CO₂ and H₂O when burned. EVOH resin is considered a green packaging material, environmentally friendly and aligned with sustainable development trends.

1. PRODUCT APPLICATIONS

EVOH resin is widely used in:

Food packaging: sausages, ham, sauces, beverages, yogurt, confectionery.
Pharmaceutical and cosmetic packaging: tablets, powders, creams, gels, shampoos.
Automotive industry: fuel tanks, gasoline containers, oil pipes, gas pipes.
Technical materials: heating pipes, medical tubes, cable protection conduits.

The product can be processed by multi-layer extrusion, blow molding, sheet extrusion, and lamination. It is easily combined with PE, PP, PET, and PA to produce multi-layer packaging with excellent puncture resistance and gas barrier properties.

2. TECHNICAL NOTES

EVOH is hygroscopic and should be stored in vacuum-sealed packaging, kept in a dry and cool place.
Avoid direct exposure to high temperature and humidity during storage.
During processing, cylinder temperature should be maintained at 190–220°C, and must not exceed 240°C.
Residence time in the machine should not exceed 30 minutes to prevent property degradation.
Clean the machine with LDPE before switching to other materials.
