In the wine bottle packaging market, special-shaped wine bottles have always been classified as alternative packaging, mainly because some liquor manufacturers put them on the market for commemoration and limited quantity. The reason why manufacturers do not use special-shaped wine bottles on a large scale is because special-shaped wine bottles are often expensive, which is not conducive to assembly line production and filling, and special-shaped wine bottles are very unfavorable for loading and transportation. This makes the use of special-shaped wine bottles on the market very small.
