Films and Packaging Applications
SEKISUI Selvol™ polyvinyl alcohol (PVOH/PVA) resins play a key role in high-performance, sustainable films and packaging. They offer barrier properties and process flexibility across industries.
Benefits of Selvol Polyvinyl Alcohol in Films and Packaging Applications
Selvol PVOH and Ultiloc resins offer unique, valuable attributes for versatile barrier systems:
- Possible water solubility
- Possible biodegradability and compostability
- Oxygen and other gas and odor barrier properties
- Solvent, oil and grease resistance
- Inherently antistatic properties
- Innocuous and environmentally friendly properties
Ultiloc: Distinct Benefits for Flexible Film Systems
Selvol Ultiloc barrier resins have verified gas barrier performance with higher adhesion properties. This makes them an excellent fit for a variety of flexible films and packaging applications. For example, Selvol Ultiloc barrier resins offer these specific benefits:
- Thinner films with lower gauge weights
- Potential for fewer layers in laminate structures, without adhesive tie layers
- Better film clarity
- Potential replacement of other barrier technologies

Next-Generation Products With Ultiloc 5003
One standout product in our portfolio, Selvol Ultiloc 5003, delivers exceptional performance for PVOH films in flexible packaging applications.
Selvol Ultiloc 5003 offers these characteristics:
- Superior oxygen transmission rate (OTR)
- Zero chlorine
- Higher reactivity for greater crosslinking characteristics to improve moisture vapor transmission rate (MVTR)
- Excellent adhesion and the ability to be coated directly onto corona-treated BOPP and BOPET
- This indicates adhesive tie layers are unnecessary, and it produces thinner, simpler laminate films.
- Ultra-clear coating production
- Heat-sealable attributes
These qualities make it an excellent choice for barrier applications.

Films and Packaging Application FAQs
What barrier properties does Selvol PVOH provide in films and packaging applications?
Selvol PVOH resins deliver oxygen and gas barrier performance, solvent and grease resistance and inherently antistatic properties. They also offer potential water solubility and biodegradability. That makes them a strong fit for packaging manufacturers pursuing both performance and sustainability goals.
How does Selvol Ultiloc differ from standard PVOH for flexible film applications?
Selvol Ultiloc barrier resins provide verified gas barrier performance with higher adhesion properties than standard PVOH. They enable thinner films with lower gauge weights and can eliminate adhesive tie layers in laminate structures. Ultiloc is a patented copolymer series exclusive to SEKISUI; this combination of barrier performance and adhesion isn’t available from commodity PVOH suppliers.
What are the key performance characteristics of Selvol Ultiloc 5003?
Selvol Ultiloc 5003 delivers a superior oxygen transmission rate (OTR), zero chlorine, higher crosslinking reactivity for improved moisture vapor transmission rate (MVTR) and heat-sealable attributes.
It maintains strong barrier performance at up to 65% relative humidity and is capable of replacing traditional barrier materials such as PVdC and EVOH in many laminate configurations. You can coat it directly onto corona-treated BOPP and BOPET substrates, eliminating adhesive tie layers and producing ultra-clear, thinner laminates.
Can Selvol PVOH resins replace existing barrier technologies in my packaging line?
It depends. We engineer Selvol Ultiloc resins to serve as potential replacements for other barrier technologies. Their combination of gas barrier performance, adhesion and compatibility with flexible film structures makes them a technically viable alternative in many laminate packaging configurations. Contact our Technical Service Team to evaluate fit against your current system.
Are SEKISUI’s films and packaging resins compatible with sustainability requirements?
Yes. Selvol PVOH resins offer possible biodegradability and compostability, along with inherently environmentally friendly properties. These attributes support manufacturers working to meet recyclability, compostability or sustainability targets without compromising functional performance.
