Abstract
Methods of making recyclable heavy-gauge films are provided. The methods of the present disclosure involve bonding the inner layers of a coextruded blown film together such that the film is sufficiently thick enough for it to be oriented in the MDO section using the typical 5:1 orientation ratio and result in a film with twice the gauge typically made by the MDO process (while maintaining acceptable stiffness and dimensional rigidity). Recyclable heavy-gauge films formed by the methods are also provided.
