<p>Composite web intended for manufacturing sterile, thermoformed packaging for liquid and/or pasty products, which composite web is of the type comprising, on the one hand, a first multi-layer or single-layer web whose so-called inner layer or face intended to delimit the interior of the packaging is thermoplastic, heat-sealable and sterile, and, on the other hand, a protection web which adheres in a leaktight but peelable manner to the sterile face of the said inner layer or face. According to the invention, the protection web consists of a second multi-layer or single-layer web (102, 119, 146, 158) of identical composition to that of the first multi-layer or single-layer web (2, 19, 46, 58) and whose inner thermoplastic layer with a sterile internal face (108, 147, 159) adheres in a leaktight but peelable manner to the sterile internal face (8, 47, 59) of the inner thermoplastic layer of the said first multi-layer or single-layer web. <IMAGE></p> |
