<p>PROBLEM TO BE SOLVED: To provide a cover sheet for PTP(press through package) in which the cover material and the bottom material are not required to separate from each other after use of PTP and which can be easily recycled and disposed and also which is favorable in the environmental protection and in a uniform push-through property. SOLUTION: The cover sheet for PTP with 0.01-1mm thickness is composed of a resin A containing at least one of a polyolefin, a polyester, and polystyrene or a styrene copolymer and an inorganic filler B. The volume ratio of the resin A to the inorganic filler B is 95-40:50-60 (volume %, A:B). The burst strength of the sheet is 0.01-5kg/cm<2> in the Mullem low pressure tester of JIS P 8112.</p> |
