A dental appliance for positioning a patient's teeth includes a removable orthodontic tooth positioning appliance having teeth receiving cavities shaped to directly receive at least some of the patient's teeth and apply a resilient positioning force to the patient's teeth. The appliance includes a hard polymer layer having a hard polymer layer elastic modulus disposed between a first soft polymer layer having a first soft polymer layer elastic modulus and a second soft polymer layer having a second soft polymer layer elastic modulus. The hard polymer layer elastic modulus is greater than each of the first soft polymer layer elastic modulus and the second soft polymer layer elastic modulus. At least one of the first soft polymer layer and the second soft polymer layer has a flexural modulus of greater than about 35,000 psi.

A method for manufacturing a laminate sheet including a fluororesin film and a silicone rubber sheet that are adhered to one another, where the fluororesin film has a reactive functional group as a result of a surface treatment, the side with the reactive functional group is overlapped with an organic peroxide-containing millable-type silicone rubber composition, where the silicone rubber composition is sheet-shaped and the organic peroxide has a one-minute half-life temperature in the range of 100−150° C., and the silicone rubber composition is cured by being heated under pressure at 90-135° C. The laminate sheet has a peel adhesion strength of 3N or more. The four corners of a 120 mm square test sample of the laminate sheet do not curve into one end of a semicircular arc shape or one end of a C shape, and the average warpage value of the four corners is 35 mm or less.
