The basically inert or inactive molecular structure of pp and pe is described as a low energy state.
What will stick to polyethylene.

If exposed to flame the surface layer undergoes chemical changes that dramatically improve bonding.
High density polyethylene hdpe is used for milk cartons fuel tanks and pipes.
These plastics are designed to take a beating and are generally chemically resistant.
However recent innovations have created epoxy based glues that allow hdpe to be attached to other polymers such as pvc fiberglass and steel.
Even un cured caulk barely sticks.
The loctite all plastic super glue includes a tube of bonding agent and a bottle of surface activator.
According to the ridout plastics company such chemically.
I bet you could get a coal to stick to a boat.
You can enforce it using an increased surface sanding or oxidizing flame but the best thing to attach something.
This is why the tips of caulking guns are polyethylene.
This group includes teflon or polytetrafluoroethylene.
While the chemistry of polyethylene is stable it will burn.
Polyethylene and polypropylene plastics are used in a number of packaging shipping and production products including plumbing fittings bottles and automotive parts.
It bonds with hard and soft plastic.
However making polyethylene bond to itself or to any other material typically takes industrial scale measures.
Gluing polyethylene can be difficult however polyethylene can be bonded.
The glue works well with polyethylene and polypropylene surfaces.
But there is a partial solution to using an adhesive sealant with polyethylene.
Previously hdpe could only be welded together by melting the surface of the hdpe.
Because of polyethylene s non stick properties it is commonly used as packaging material for tapes and adhesives.
It is often abbreviated to ldpe low density polyethylene or hdpe high density polyethylene.
Nothing pe can t be glued the same way like other polymers the bonds are too weak.
Polyethylene is a lightweight thermoplastic.
Whenever and wherever we state that we can bond polyethylene polypropylene or any other polymer the universal reaction is skepticism.
Finally with the bonding poly process patent pending bonding any polymer is always quick easy and permanent.
