The Polyfuze Difference

Polyfuze Fusion Labels

Compatible with Polyolefin Plastics

Other Label Sources

Incompatible with Polyolefin Plastics

Permanency Is Dependent On The Nature Of Polyolefins

As the most widely used plastic in the world, Industrial Designers and Engineers source durable & cost-effective polyolefins for their natural ability to resist chemicals, extremely harsh environments and heavy impacts. Those same natural abilities make them impossible to label permanently.

Like Teflon™, this same natural ability is simultaneously and continuously opposing bonding and adhesion from incompatible label sources causing costly failures.

4 Natures Of Polyolefin Plastics
Causing Labeling Failures

Incompatible labeling sources are produced using “off the shelf” inks including UV coatings to protect them from exposures to harsh elements/weather conditions. Once printed on the base substrate, specially formulated adhesives or bonding layers are applied with intention to “stick” or “bond” to the unique surface of polyolefin plastics. Due to the incompatible nature of polyolefin plastics (surface similar to Teflon™) the “stick” or “bond” adhesion eventually delaminates resulting in label failure.

By comparison, Polyfuze Labels are produced from proprietary pigmented polymers that are 100% compatible with polyolefin plastics. Once the fusion process is complete, Polyfuze Label and polyolefin product combine forming one piece of seamless plastic. Evidence has shown the only option for longevity and true label permanence is Polyfuze Fusion Labeling Technology.

Polyfuze Fusion Technology provides the ultimate solution for labeling polyolefin plastics.

Non-Polar

Non-Polar – Non-porous and chemically inert polyolefin surfaces have no bonding site for adhesives or tie layers to grasp onto for longevity.

“Polyolefins, by their nature, do not lend themself to any method of adhesion. The polyolefin material is non-porous, it is resistant to attack by solvents useful in adhesive formulations, and it has a non-polar chemical structure.”  –  Phil Dodge, Equistar Chemical

Low Surface Energy (LSE)

LSE Polyolefins Create Labeling Problems.

A great example of low vs. high surface energy is a waxed vs. unwaxed car. Before waxing, the cars surface energy is higher than rainwater causing it to easily wet out over the surface. Waxing the car lowers the surface energy below rainwater causing it to bead up and run off freely. Polyolefin plastics have lower surface energy than adhesives causing incompatible labels to delaminate from the surface allowing chemicals, moisture and other elements to attack from underneath.

Surface Energy Dyne Levels

HIGH SURFACE ENERGY
Stainless Steel  = 700-1100
Aluminum  = 840
Glass  = 250-500

LOW SURFACE ENERGY
LSE Polyethylene =   31
LSE Polypropylene  = 29
PTFE (Teflon)  18

Expand/Contract

Flexible polyolefin plastics Expand & Contract 18 times more than metal. Subsequently, rigid incompatible label construction loses structural integrity while delaminating from the surface allowing chemicals, moisture and other elements to attack from underneath.

Outgassing

Surfactants, blooming and slip agents compounded into polyolefin plastics cause them to continually outgas. This outgassing creates a barrier between the label and product causing labels to delaminate allowing chemicals, moisture and other elements to attack from underneath.

Heat Transfers are constructed of incompatible inks, coatings and heat activated adhesives printed onto rolls of PET film. The label is then applied to polyolefin products using a Heat Transfer Machine set to 300°F-350°F @ 500psi where the adhesive attempts to adhere to a surface that is:

Non-Polar = No bonding site for adhesive or tie bonding layers to grab.
LSE = Like *Teflon™, polyolefins reject adhesion causing label detachment.
Expand/Contract = Incompatibility causes label craze & detachment.
Outgas = Creates barrier at polyolefin surface causing label detachment.

For durable polyolefin products that require permanent labeling that last the life of the products, this method fails and produces problems.

Hot stamping utilizes a metal or silicone die which is heated and then forced down against a polyolefin product with a layer of incompatible pigmented adhesive sandwiched in between. When the die is set to 300°F-350°F @ 500psi and comes into contact with the part, the ink remains on the product surface that is:

Non-Polar = No bonding site for adhesive or tie bonding layers to grab.
LSE = Like *Teflon™, polyolefins reject adhesion causing label detachment.
Expand/Contract = Incompatibility causes label craze & detachment.
Outgas = Creates barrier at polyolefin surface causing label detachment.

For durable polyolefin products that require permanent labeling that last the life of the products, this method fails and produces problems.

In Mold Labels (IML’s) are constructed of semi-compatible substrate layer printed with incompatible inks which is then coated with a UV print,
polypropylene or polystyrene layer to protect it. Although the substrate has olefinic qualities, when applied to polyolefin products, the construction remains incompatible with surfaces that are:

Non-Polar = No bonding site for adhesive or tie bonding layers to grab.
LSE = Like *Teflon™, polyolefins reject adhesion causing label detachment.
Expand/Contract = Incompatibility causes label craze & detachment.
Outgas = Creates barrier at polyolefin surface causing label detachment.

For durable polyolefin products that require permanent labeling that last the life of the products, this method fails and produces problems.

Pressure sensitive adhesive labels are constructed of a base substrate printed with incompatible inks and a protective coating which is then coated with a formulated pressure sensitive adhesive. They are categorized as permanent or removable based on whether they achieve a peel strength of two pounds or more from high surface energy (HSE) stainless steel. A problem when applied to polyolefin product surfaces that are:

Non-Polar = No bonding site for adhesive or tie bonding layers to grab.
LSE = Like *Teflon™, polyolefins reject adhesion causing label detachment.
Expand/Contract = Incompatibility causes label craze & detachment.
Outgas = Creates barrier at polyolefin surface causing label detachment.
