What makes polyethylene difficult to bond with?
When applying any adhesive or paint to a solid, how well the solid “accepts” any coating can be gauged by its surface energy. The surface energy of a solid is a measure of the energy it takes to create a surface on the material. The adhesive, in our case, would account for the “surface” and the polyethylene will be the “material.”

This makes solvent welding, ultrasonic or infrared welding or induction heating a good method of bonding polyethylene (to itself). However, if you need to bond it to a different type of plastic or substrate such as wood, metal, rubber or some kind of composite, it is necessary to look to some other joining method such as industrial adhesive bonding.
What is LDPE in packaging?
Polyethylene is a lightweight thermoplastic. It is often abbreviated to LDPE (low density polyethylene) or HDPE (high density polyethylene). Bonding polyethylene is considered very difficult and as a result it is often used as packaging for adhesive materials – as the glue won’t stick to it!
