Silicone Release Liners
The latest technology in coating and converting to meet your demand
Customized Release Liners For Your Products...
Silicone release liners make a big impact in a lot of little ways throughout our daily lives. From the bandage paper we peel away after a nasty paper cut to the backing of every postage stamp we place, silicone release paper keeps a wide variety of adhesives fresh and tacky. While normal paper bonds to adhesives, release paper is designed specifically to be easy to pull away, without the risk of it falling off.
Utilizing the natural properties of silicone, this release paper sticks to the adhesives without fusing. Just a little pressure is enough to pull away the coated paper from its adhesive, and the adhesive remains tacky and fresh for its intended application. Silicone release paper is also naturally water-resistant and anti-microbial.
As a global supplier of release liners for all adhesive, rubber, electronic, circuit, and sealant-related products, we utilize the latest technology in coating and converting to meet your demand. At Griff, we can customize to your specifications. If you need silicone release liners in rolls, sheets or die-cut, we can do that in our facilities.
Griff’s Release Liners are designed to not only release the stress of adhesive paper or tape but to release our clients’ stress of monitoring quality control. Following hours of research and development along with industry-standard testing, we have reached a result that can be customized for thousands of different applications. All of the release coatings are formulated without solvents and polymerized using Green Technology. These products are manufactured in a climate-controlled facility that is ISO 9001:2015 certified to maintain the highest level of quality.

APPLICATIONS
Application Tape
Application tape allows a printed or die-cut object to be placed onto another surface without compromising the quality or shape of the object.
Benefits:
- Simple release
- Multiple applications
- Easy die-cutting
A design that is printed onto a colored piece of vinyl by a printer can be transferred onto another surface with pressure or moisture. Items like a die-cut sticker that you see on the back of a car window or on a store front door are an example of this. Application tape is the peel-off release that is applied to the vinyl to be released after being attached to the surface.
Application tape can be applied to countless die-cuts, sizes, and colors. Application tape is easy to erase, greaseless, and leaves behind minimal residue.

SUBSTRATES
Biaxially Oriented Polypropylene Film (BOPP)
BOPP Film is a biaxially oriented polypropylene (BOPP). “Biaxially oriented” reveals that the polypropylene film has been stretched in both the machine direction (MD) and across machine direction (AMD). Superior strength at low gauges (allows for high speed processing), flatness, clarity and printability, are just a few of the reasons BOPP film has become the most rapidly implemented film product around the world.
This material has good clarity, resistance to UV light, excellent chemical and abrasion resistance, and a smooth surface. The clear material has a reasonable scuff resistance and a great acid resistance.
Our material is also inert to most mild chemicals and has a fair heat resistance allowing for heat sealable BOPP films. This material is softer and more flexible than polyester.
We have the BOPP film for you, no matter your application. There are over 1,000 variants of BOPP films.
Available BOPP films:
- Laminated BOPP film
- Industrial BOPP film
- Metallized BOPP film
- Co-extruded BOPP film
- Tape BOPP film
- Label BOPP film
- Packaging BOPP film

High Density Polyethylene Film (HDPE)
With a low coefficient of friction, high density polyethylene film (HDPE) is prized for its slip resistance and release properties, as well as its excellent impact, tensile, and compression strength. Dense and unbranched, this material does not splinter, corrode, or abrade easily and is stress-crack resistant.
Benefits:
- Slip-resistant
- Strong
- Food-safe
- Moisture resistant
- Stain resistant
- Odor resistant
- Printable
HDPE film does not retain harmful bacteria, is extremely resistant to various cleaning agents and can be sterilized in boiling water. Its clarity makes for appealing food packaging, while its slip resistance is valuable in textile packaging. This material is available clear or opaque in a variety of colors, and can be customized in size, shape, and density to suit your needs.

Low Density Polyethylene Film (LDPE)
Soft, tough and flexible, low density polyethylene film is favored for its resilience against a majority of chemicals and organic solvents. When LDPE film is incorporated into a packaging laminate, it offers excellent seal strength to package the most demanding products. Its low conductivity makes it useful in low temperature electrical applications, while its durability and excellent process-ability make it the all-purpose film to turn towards.
Benefits:
- Superior flexibility
- Excellent process-ability
- Optimum tear strength
LDPE film is polymerized using a free radical that produces a large amount of short and long chains, limiting its ability to form high levels of crystallization. The low level of crystallinity attributes to the flexibility, clarity and elongation. The simple repeating polymer unit is very inert, leaving the film resistant to many chemicals. While LDPE is very popular as the main resin for shrink film and sealing layers in packaging laminates, we customize our film to suit many purposes and can adjust everything including color, thickness, size, printability, release and finish.
