Double sided foam tape is a permanent bonding solution as a cold glue alternative for a polyethylene tarp adhering to another polyethylene tarp. There is no solvent that has been specifically made as a cold glue for polyethylene but are solutions as alternatives.
Hot welding with a polyethylene stick is the only way. No glue has yet been made that will effectively adhere to polyethylene.
Adhesives are used to bond (or stick) one surface to another, either temporarily or permanently.
Polyethylene glue is an 'urban myth'. Modern polyethlene materials are purposely so chemical resistant that no glue has yet been made that will bond them ! Polyethylene pipes are bonded by 'hot air' welding, not by any glues. They can be held together by contact adhesives, but the joint is very weak and will not hold even 30psi of water or air pressure.
Another name for a dative covalent bond is 'coordinate covalent bond'.
The transfer of an electron from one atom to another results in an ionic bond.
I will answer your question, my word is my bond.
ionic bond
Adhesive glue sticks to many surfaces and as the carrier dries, it will bond to the surface more permanently
ionic bond
Polypropylene is stronger that polyethylene. High resistance to environment. Have higher melting point. The chemical reason is that polypropylene have triple bond carbon. However, polyethylene have only double carbon bonded to each other.
My word is my bond. The glue will bond your two pages together firmly.
