An object of the present invention is to provide a stitched fiber-reinforced substrate material capable of suppressing the formation of microcracks in a fiber reinforced composite material. The stitched fiber-reinforced substrate material of the present invention is a fiber-reinforced substrate material formed by stitching reinforcement fiber sheets made of reinforcement fibers using stitching yarns, and the stitching yarn has a linear expansion coefficient in the fiber axial direction of −1×10.sup.−6 to 70×10.sup.−6/K after being heated at 180° C. for 2 hours and then cooled. The stitching yarn is preferably a stitching yarn to which an organic compound having a polar group is adhered.

A multi-layer film comprising, an outer two layers of the multi-layer film comprising a linear low density polyethylene (LLDPE) butene resin, a next two inwardly successive layers of the multi-layer film comprising a linear low density polyethylene (LLDPE) hexene resin, wherein at least one of the next two inwardly successive layers comprises one or more recycled resin components, wherein at least one of the one or more recycled resin components are filtered using continuous filtration, a core layer of the multi-layer film comprising a linear low density polyethylene (LLDPE) hexene resin, and at least one edge of the multi-layer film comprising a folded edge.

A composite stretch film for agricultural use is formed by bonding two stretch films together with an adhesive through hot rolling or UV curing such that primary stretch directions thereof cross each other. The composite stretch film of the present invention is significantly improved not only in transverse and longitudinal tensile strength but also in transverse and longitudinal tear strength. Therefore, it is able to meet the requirements for use in agriculture with a lesser thickness and hence reduce the use cost. In particular, in case of the composite stretch film being made of a polyester material, it further offers the advantages such as high-light transmittance which changes mildly with time, better thermal insulation properties and better humidity-regulating capabilities. In particular, in case of it being made of a degradable polyester materials, it will further offer profoundly significant benefits in terms of energy saving and environmental protection.

A filter medium includes first and second porous films mainly containing fluororesin, and a pre-collection member upstream of the first film. The second film is downstream of the first film. The pre-collection member has a pressure drop when air is passed through at a flow rate of 5.3 cm/s of between 15 Pa and 55 Pa, a collection efficiency of NaCl particles having a particle diameter of 0.3 μm when air containing the particles is passed hrough at a flow rate of 5.3 cm/s of between 25% and 80%, a thickness of 0.4 mm or less, and a PF value between 7 and 15. The PF value={−log((100−collection efficiency (%))/100)}/(pressure drop (Pa)/1000). A ratio of the PF value of the pre-collection member to the PF value when the first and second films are overlapped, is between 0.20 and 0.45. The filter medium can be used in a filter pack or filter unit, and may be produced by integrating the first and second films and the pre-collection member using heat lamination.

The present invention relates to a packing body of a composite laminate, including: a bottom supporting portion; a back-surface supporting portion; a pressing portion; and a fastening mechanism. The fastening mechanism is provided in only a central region in an up-down direction, in both of upper and lower regions, or in all of the upper, the central, and the lower regions. An end-to-end dimension from an end portion of the glass sheet in a region corresponding to the fastening position to a nearest end portion of the resin film is 5 mm or more and 30 mm or less. An average value of gap distances, each of which is a distance between facing sheet surfaces adjacent to each other in the region corresponding to the fastening position, is 20 μm or more and 80% or less of a thickness of the resin film before fastening.
