A copolymer is a polymer formed when two (or more) different types of monomers are linked in the same polymer chain, as opposed to a homopolymer where only one monomer is used.
Basically copolymers are used in sealable film.
Heat Sealable Films are Multi – layered films that comprises of an outer coating which prevents it from melting the core of the film and damaging it.Heat sealable films are sealable to itself and not peelable. These are suitable e.g. for food packaging and roasting bags.
