1. A multilayer bag comprising: an outer paper layer;an inner paper layer; anda synthetic intermediate layer located between said outer paper layer and said inner paper layer;wherein said outer paper layer, said inner paper layer, and said synthetic intermediate layer are configured to form a longitudinal overlap region, said overlap region comprising a first edge of said outer paper layer overlapping an opposite second edge of said outer paper layer, and comprising a first edge of said synthetic intermediate layer overlapping an opposite second edge of said synthetic intermediate layer, said first edge of said outer paper layer being discontinuously adhered to said second edge of said outer paper layer by a plurality of adhesion points in said overlap region. 2. The multilayer bag of claim 1, wherein said adhesion points are formed in at least one line along a longitudinal axis of said overlap region. 3. The multilayer bag of claim 1, wherein said adhesion points are formed in two parallel lines along a longitudinal axis of said overlap region. 4. The multilayer bag of claim 3, wherein said adhesion points of said two parallel lines are aligned adjacent to each other in a non-staggered manner. 5. The multilayer bag of claim 3, wherein said adhesion points of said two parallel lines are arranged in a staggered manner. 6. The multilayer bag of claim 1, wherein said synthetic intermediate layer comprises a synthetic film formed of a polyolefin including at least one of polypropylene, polyethylene, a copolymer of polypropylene and polyethylene, and a mixture of polypropylene and polyethylene. 7. The multilayer bag of claim 1, wherein said synthetic intermediate layer has a thickness in a range of 10 μm to 100 μm. 8. The multilayer bag of claim 1, wherein said synthetic intermediate layer comprises a first synthetic intermediate layer, further comprising a second synthetic intermediate layer adjacent to said first synthetic intermediate layer and forming a barrier layer.
