An intraoral x-ray film packet is taught which has an outer envelope wherein one of the two opposing outer sheets is more rigid than the other and serves as a stiffening sheet such that it has a tensile modulus of at least about 700 Kg/cm2. This is preferably accomplished by making both sheets from a thermoplastic material such as PVC and reducing the amount of plasticizer in the more rigid of the two sheets to less than 30%. A continuous perimetric seal is formed affixing the two outer sheets together and forming a perimetric laminated edge which is substantially coplanar with the more rigid of the two sheets. A film chip resides between the two outer sheets. The coplanar perimetric laminated edge and the added rigidity aid in improving accurate sizing of each individual packet and prevention of deflection of the marginal area of individual packets in subsequent operations.
