A B S T R A C T A container made of sheets of fibrous material, these sheets adhered together by glue, and a tape for reinforc- ing at least part of the container. The tape is adhered flat to the fibrous material over substantially its entire length. The tape has a thickness lying between 0.05 and 0.30 millimeters. The tape is weftless and is made of parallel yarn ends, each made of several fibers selected from the group consisting of polyester, rayon and polyamide fibers, and an adhesive bonding the yarn ends together. Each of the yarn ends has a gauge range from 100 to 12,000 deniers, there being up to 350 yarn ends in the tape. The yarn ends are flattened with their major cross- sectional dimension being greater than the diameter of the original round yarn ends used for making the tape by an amount varying between 35% and 100%. The adhesive fills the interstices between the yarn ends and provides a generally smooth surface at the main faces. The adhesive is chosen to be compatible with the glue.
