You can enforce it using an increased surface sanding or oxidizing flame but the best thing to attach something.
What will stick to polyethylene.
But there is a partial solution to using an adhesive sealant with polyethylene.
However recent innovations have created epoxy based glues that allow hdpe to be attached to other polymers such as pvc fiberglass and steel.
Polyethylene and polypropylene plastics are used in a number of packaging shipping and production products including plumbing fittings bottles and automotive parts.
This group includes teflon or polytetrafluoroethylene.
If exposed to flame the surface layer undergoes chemical changes that dramatically improve bonding.
This is why the tips of caulking guns are polyethylene.
It bonds with hard and soft plastic.
Finally with the bonding poly process patent pending bonding any polymer is always quick easy and permanent.

Even un cured caulk barely sticks.
While the chemistry of polyethylene is stable it will burn.
Previously hdpe could only be welded together by melting the surface of the hdpe.
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.
Polyethylene is a lightweight thermoplastic.
I bet you could get a coal to stick to a boat.
Because of polyethylene s non stick properties it is commonly used as packaging material for tapes and adhesives.
The loctite all plastic super glue includes a tube of bonding agent and a bottle of surface activator.
These plastics are designed to take a beating and are generally chemically resistant.
Polypropylene and polyethylene are called low energy or non stick plastics.
Gluing polyethylene can be difficult however polyethylene can be bonded.
Nothing pe can t be glued the same way like other polymers the bonds are too weak.
Whenever and wherever we state that we can bond polyethylene polypropylene or any other polymer the universal reaction is skepticism.
According to the ridout plastics company such chemically.
However making polyethylene bond to itself or to any other material typically takes industrial scale measures.
The glue works well with polyethylene and polypropylene surfaces.
It is often abbreviated to ldpe low density polyethylene or hdpe high density polyethylene.
