Fully automatic self-adhesive double-side labeling machines / fully automatic self-adhesive single-side labeling machines perform labeling operations on square bottles and flat oval bottles. Their core difficulties center on curved surface adaptability of containers, positioning accuracy and the bonding stability of self-adhesive labels, with highly targeted pain points.
Square bottles feature sharp edges and folded corners at panel joints. During labeling, labels tend to lift and wrinkle along edges, with poor adhesion at panel transition zones; positioning deviation of bottle bodies also easily results in skewed labels. Flat oval bottles are structured with two flat planes plus curved side surfaces with drastically varying radians. Uneven stress applied to self-adhesive labels during attachment leads to air bubbles and tensile deformation, while positioning offset occurs more frequently under high-speed labeling conditions.
Moreover, these two container types cover numerous specifications, bringing complicated format changeovers. The adhesiveness of self-adhesive labels is greatly affected by temperature and humidity, causing label peeling and sticking together. Static electricity and dust on bottle surfaces weaken label bonding strength, accompanied by high label material consumption. All these issues jointly limit labeling efficiency and standardized production, constituting the major bottleneck for self-adhesive labeling of square and flat oval bottles.
