TECHNOLOGY FOCUS - POLYMERS - Preferred Properties: The adhesive layer has thickness of 10 mu m-5 mm. The synthetic resin material comprises polyethylene-type resin having density of 0.92-0.97 g/cm3 and high load melt flow rate of 2-70 g/10 minutes at 190 degrees C and load of 211.8 N based on JIS K6922-1 (1997). Preferred Component: The adhesive agent comprises polyolefin-type resin containing functional group chosen from carboxylic acid group or carboxylic anhydride group, epoxy group, hydroxyl group, amino group and silyl group. The adhesive agent comprises adhesive resin (Z) containing polyethylene-type resin (X) (0.5-100 weight%) and unmodified polyethylene-type resin (Y) (0-99.5 weight%). The adhesive resin (Z) has density of 0.86-0.97 g/cm3 and melt flow rate of 0.01-100 g/10 minutes. The polyethylene-type resin (X) is chosen from high-density polyethylene resin (A) having density of 0.94-0.97 g/cm3 and melt flow rate of 0.01-100 g/10 minutes, linear-low-density polyethylene resin (B) having density of 0.9-0.94 g/cm3 and melt flow rate of 0.01-100 g/10 minutes, high-voltage radical method polyethylene-type resin (C) having melt flow rate of 0.01-100 g/10 minutes and very-low-density polyethylene resin (D) having density of 0.86-0.9 g/cm3 and melt flow rate of 0.01-100 g/10 minutes. The unmodified polyethylene-type resin (Y) is chosen from high-density polyethylene resin (A) having density of 0.94-0.97 g/cm3 and melt flow rate of 0.01-100 g/10 minutes, linear-low-density polyethylene resin (B) having density of 0.9-0.94 g/cm3 and melt flow rate of 0.01-100 g/10 minutes, high voltage radical method polyethylene-type resin (C) having melt flow rate of 0.01-100 g/10 minutes, very-low-density polyethylene resin (D) having density of 0.86-0.9 g/cm3 and melt flow rate of 0.01-100 g/10 minutes and thermoplastic elastomer. Preferred Process: The polyethylene resin (A, B or D) are manufactured using single site-type catalyst. The nozzle component is processed by surface treatment agent. Preferred Composition: The adhesive resin comprises polyethylene-type resin (X) (5-95 weight%) and unmodified polyethylene-type resin (Y) (5-95 weight%). The content of functional group of adhesive agent is 0.001-30 weight%. Preferred Material: The synthetic resin liner material is a composite material and material chosen from engineering plastics, metallic component and inorganic filler dispersed in the resin. A synthetic resin liner material comprises laminated component having thermoplastic resin layer, adhesive layer or barrier layer. The reinforcing material is reinforcing fiber material.
