Abstract
Pressurized plastic container having the appearance of ribs but with substantially reduced creep and without delamination, i.e., having an enhanced shelf life compared to prior art ribbed containers. In multilayer containers, the scribe lines reduce delamination of the layer structure so as to avoid loss of transparency and/or barrier properties. The reduction in creep is particularly useful for smaller volume containers having a greater surface area to volume ratio.
