The present invention is directed to a cold seal package (10) that includes constructions wherein two substrates (12, 18) or two portions of one substrate, are sealingly engaged to one another using a substantially natural latex rubber-free contact adhesive (14, 16). The two substrates can be easily peeled apart without substantial damage to the substrates. Furthermore, the substrates cannot typically be resealed, or refastened, once peeled apart. That is, the cold seal formed by the adhesive between the substrates is substantially non-refastenable. Advantageously, a cold seal package of the present invention is particularly well suited for aseptic delivery of packaged goods, such as bandages, dressings, and the like.
L'invention concerne un emballage (10) à soudure par pressage à froid, formé de constructions dans lesquelles deux substrats (12, 18) ou deux parties d'un substrat, sont soudés l'un à l'autre, grâce à un adhésif de contact (14, 16) sensiblement exempt de caoutchouc naturel. Les deux substrats peuvent être séparés facilement l'un de l'autre sans que cela les endommage. De plus, ils ne peuvent généralement pas être resoudés, ou refixés, une fois séparés. La soudure à froid formée par l'adhésif entre les substrats ne peut sensiblement pas être reformée. Un emballage à soudure à froid de l'invention convient particulièrement à la distribution aseptique de produits emballés, tels que des bandages, des pansements et similaire.
