A combination of polymer and polyamide is one of the most widely used polymers. This polyethylene has branched chains, so LDPE chains can not be well bonded to each other, with less intermolecular force and less elasticity. Polyethylene has low and low molecular densities of low density, which increases its flexibility.
Films made of LDPE have good optical properties, impenetrability, odorless and chemically neutral.
Its applications include: packaging of bread and food, greenhouse nylon, industrial packaging bag.
