A low-cost tamper-resistant product package is provided. The package comprises a substantially flat thermoplastic sheet forming a package backing, and a molded plastic cover sealed to the backing. The backing and cover are preferably formed of a plastic, such as polyvinyl chloride or polyethylene, that is difficult to puncture, cut or tear. The seal between the backing and cover is preferably difficult to compromise, so that human hands have great difficulty separating the backing and cover. RF welding and ultrasonic welding are preferred methods of sealing the package. The plastic backing is adapted to be printed upon directly. The cover preferably includes a ridge around its perimeter to inhibit bending of the package and assist in package display. The cover also preferably includes at least one bulge, forming therein a hollow recess for housing a product.

1. A product package to deter theft and prevent unauthorized access to the product, the package comprising: a flat, thin, opaque thermoplastic sheet forming a backing, the backing having printing with at least two colors thereon; and a thermoplastic cover having at least one cavity formed therein, the cavity creating a product-enclosing space in combination with the backing, the area of product-enclosing space on the backing being substantially smaller than the area of the cover, such that the package is not easily concealed on one's person, the cover having a raised ridge at least partially surrounding and spaced outwardly from the product enclosing space, the cover also having a lip that surrounds edges of the backing and restricts access to the edges of the backing; wherein a peripheral portion of the backing is permanently secured to a peripheral portion of the cover through an RF weld, an ultrasonic weld, a UV weld, a heat seal, or an adhesive, the thermoplastic forming the backing and the cover being strong, tough and highly resistant to manual tearing or puncturing, such that the product-enclosing space is substantially inaccessible unless the backing and/or the cover is cut with a cutting instrument or otherwise destroyed by non-manual means. 2. The package of claim 1 wherein the backing and the cover are constructed of polyvinylchloride. 3. The package of claim 1 wherein the backing includes printing on two opposite surfaces. 4. A method of packaging a product to deter theft and prevent unauthorized access to the product, the method comprising the steps of: printing in at least two colors on first and second surfaces of a first sheet of plastic, the first sheet of plastic forming a backing for a product package; creating a recess in a second sheet of plastic, the second sheet of plastic forming a cover for the package; placing a product in the recess; and permanently securing peripheral portions of the backing and the cover together, thereby securing the product therebetween, the backing and the cover being made of strong tough plastic that is highly resistant to manual tearing or puncturing so as to prevent a would-be thief from gaining access to the product. 5. The method of claim 4, wherein the securing step comprises RF welding, ultrasonic welding, UV welding, heat sealing or the use of an adhesive. 6. The method of claim 4, further comprising the step of forming in the cover a ridge substantially encircling a portion of the cover. 7. The method of claim 4, further comprising the step of forming in the cover a lip substantially encircling the peripheral portions of the cover and the backing and restricting access to edges of the backing. 8. The method of claim 4, wherein the package does not include means to facilitate access to the recess.
