A PET bottle with patterns and/or characters embedded therein and a processing technology thereof relate to a packaging bottle with patterns and/or characters embedded therein made of polyethylene terephthalate and a processing technology thereof. The bottle is enclosed by a bottle wall into a hollow container shape; the bottle wall is of a double-layer structure comprising an inner layer and an outer layer, patterns and/or characters are formed on the inner layer and sealed between the inner layer and the outer layer; the inner layer and the outer layer are injection-molded, and are respectively made of PET material with colorant and transparent PET material. The processing steps comprise: injection-molding an inner preform in a first cavity; forming patterns and/or characters on the surface of the inner preform; transferring to a second cavity and injection-molding a layer of transparent PET as an outer preform surrounding the inner preform; heating the double-layer preform; blowing or stretch-blowing the heated double-layer preform in a blow mold to obtain a finished product. The patterns and characters can remain intact and brilliant for a long time.
