Mitsui Maleic Anhydride Grafted Modified PP Qf551 / Qf500t for PP/PE with EVOH or PA Multi-Layer Co-Extrusion

Product Description

Product Description

Using EVAL™ EVOH offers many benefits:

• At end-of-life, structures containing EVAL™ EVOH can be recycled.
• The advantage of the excellent gas barrier properties of EVAL™ resin implies that the thickness of multilayer structures can be reduced. As a result, the packaging weighs less and still protects the product and the environment.
• EVAL™ resin resist oils and chemical agents, making them particularly suitable for packaging organic solvents, agricultural pesticides and all kinds of oils, while keeping all the advantages of plastics.
• EVAL™ EVOH preserves the value of your product, reducing waste and lowering costs.
• Packaging containing EVAL™ EVOH can be adapted to just the right size, shape and proportion, without losing its protective function. This makes packing, transport and distribution as efficient and effective as possible. All this efficiency means less impact on the environment, but also more cost savings for you. Our dedicated team of technical experts will help you design smart, attractive and recycle-ready packaging.

 

Applications of EVAL™ resin

Mitsui Chemicals ADMER™ Adhesive Resin is a modified polyolefin with functional groups designed to serve as a high-performance tie layer or compatibilizer. It bonds structurally incompatible materials like polyolefins with gas-barrier resins, metals, and glass.


Food & High-Performance Packaging
Rigid Formats: Used in co-extruded bottles, cups, trays, and containers. It links structural layers to oxygen barriers.
Flexible Films: Applied in pouches, fresh food bags, and casings. It maintains protective atmosphere packaging for meat or cheese.
Coating Laminates: Bonds polymers with paperboard or aluminum foil. This is common for pet food packaging.

Automotive Engineering
Plastic Fuel Tanks: Forms the adhesive tie layer in multilayer fuel systems. It bonds HDPE to EVOH barriers.
Fuel Conveyance: Secures structural integrity in fuel lines and filler pipes. It ensures low-permeation resistance against gasoline emissions.
System Connectors: Delivers durable adhesion under high-stress automotive environments.

Industrial & Building Components
Heating & Cooling: Binds internal oxygen barriers inside floor and wall heating pipes.
Industrial Pipe Systems: Secures structural stability for multi-layered utility lines.
Industrial Composites: Serves as a coupling agent for Wood-Plastic Composites (WPC). It improves bonding in fiber-reinforced plastics (CFRP/GFRP).

Sustainability & Circular Economy
Recycling Compatibilizers: Acts as a recycling agent for multilayer films. It blends scrap PA/EVOH back into polyolefin streams.
Bio-Circular Resins: Available in ISCC+ certified plant-derived biomass grades to lower carbon footprints.

Q&A

 

Q1: What exactly is ADMER™, and how does it differ from standard polyolefins?
A: ADMER™ is a modified polyolefin (available in both PE-based and PP-based grades) pioneered by Mitsui Chemicals. Standard polyolefins (like PE and PP) are non-polar, making it difficult for them to bond with polar materials (such as EVOH, Nylon PA, aluminum foil, and metals). Through chemical grafting technology, ADMER™ introduces polar functional groups, such as maleic anhydride (MAH), onto the polyolefin molecular chains. This gives it both the compatibility of non-polar materials and extremely strong polar adhesion. It is typically used as a "tie-layer" in multi-layer co-extruded structures or as a "compatibilizer" in composite materials.

Q2: My product needs to withstand high-temperature retorting (e.g., above 121°C). Which grade should I choose?
A: If your product needs to endure high-temperature sterilization or retorting processes, it is recommended to choose the PP (polypropylene)-based ADMER™ series, as PP has a significantly higher Vicat softening point and melting point than PE.

• Top Recommendation: QB530. This grade is specifically designed for high-temperature resistance and strong adhesion. It can withstand post-processing retort sterilization at temperatures above 121°C and resists delamination even in high-temperature and high-humidity environments.
• Alternative Options: Depending on specific requirements, NF series grades optimized for high-temperature sterilization can also be considered.

Q3: My packaging film contains liquids (like milk or sauces), and I am worried about delamination due to moisture. How should I choose?
A: For liquid foods or high-humidity environments, you must select a grade with excellent hydrolysis resistance.

• Top Recommendation: NF642E. Its PE backbone structure provides superior hydrophobic properties, effectively resisting water molecule penetration. It maintains the integrity of the bonding interface even after long-term contact with liquids or in high-humidity conditions, making it the ideal choice for milk packaging films, beverage laminated pouches, and sauce packaging.

Q4: Does ADMER™ have food-grade certification? Can it be used for medical packaging?
A: Absolutely. The ADMER™ series is widely used in both food packaging and medical fields.

• Food Grade: Grades like NF642E and QB530 have passed US FDA and EU food contact material safety certifications, making them safe for various food packaging applications.
• Medical Grade: For medical device and pharmaceutical packaging that demands extremely high transparency and chemical purity, LB540 is highly recommended. Featuring high clarity and low extractables, it is the premier choice for high-end medical packaging.

Q5: Besides multi-layer packaging, are there other applications for ADMER™?
A: Yes. In addition to multi-layer co-extruded films, ADMER™ has three other major applications:

1. Automotive & Industrial Pipes: Such as automotive fuel tanks and fuel lines (recommend the ultra-high impact resistant GT6), as well as tie-layer bonding for oxygen barrier layers in underfloor heating and water supply/drainage pipes.
2. Polymer Modification Compatibilizer: When adding glass fibers, mineral fillers, or wood flour to PP, ADMER™ can act as a coupling agent/compatibilizer. It reduces filler agglomeration and significantly enhances the mechanical strength and heat resistance of the material.
3. Eco-friendly & Recycling: Mitsui's newly launched EF series (e.g., recycling agent grades) is specifically designed to improve the degradation of strength and impact resistance in recycled plastics after multiple processing cycles, supporting the circular economy.
