摘要：
Multi-layered bags include an outer layer or bag and an inner layer or bag that is shorter than the outer layer or bag. The shortened inner layer or bag can stretch or expand to the outer layer or bag when loaded with objects or otherwise strained. Such multi-layered bags can allow for a reduction in thermoplastic material without compromising the strength of the multi-layered bag. In various implementations, the inner layer or bag may be non-continuously laminated, continuously laminated, or joined only along one or more edges to the outer layer or bag. Implementations including non-continuous bonds securing the inner layer or bag to the outer layer or bag can provide additional strength to the bag. Methods of forming multi-layered bags with a shortened inner layer including inserting an inner layer within an outer layer and then joining the layers to form a bag.
