Abstract
PURPOSE:To obtain the title sheet having an antibacterial power and a capability of semipermanently retaining its antibacterial effect, by adding a specified amount of an antibacterial zeolite to a thermoplastic resin and forming the mixture into a sheet. CONSTITUTION:A sterile thermoplastic resin sheet mainly consisting of a thermoplastic resin (e.g., PS, PE, PP, polyamide, polycarbonate or polyethylene terephthalate) and an antibacterial zeolite, wherein said antibacterial zeolite is present in an amount in a range of 0.1-5wt.% based on the total weight of the thermoplastic resin and prepared by forming said composition into a sheet. This sheet can be obtained by mixing said thermoplastic resin with said specified amount of said antibacterial zeolite and extruding the mixture into a sheet at a temperature higher than the softening point of said thermoplastic resin. This sterile sheet is advantageous in that it can retain its antibacterial power and an antibacterial effect semiparmanently, the antibacterial substance is not dissolved out of the sheet and therefore does not cause the taste of food to change and it is almost nontoxic.
