Stick Pack

Provide total web width, lane layout, print repeat, unwind direction, core and roll limits, plus registration-mark requirements. Identify the seal style and cutting position for each lane. A narrow finished stick dimension does not by itself define a machine-ready roll.

Send the real powder with its flow and dust behavior and describe the intended filling process. Trial the sealant structure on the actual line, looking at product trapped in the seal and variation across lanes. Do not assume a clean laboratory seal predicts filled production.

Specify the intended opening edge and user experience, then review opening trials alongside seal and packed testing. The tear feature must work with the film structure and fill. Avoid weakening a seal margin simply to make an early hand sample easier to open.

Provide the formulation, dose, intended storage and quality targets, including sensitivity to moisture or oxygen. Request a structure proposal and product stability evaluation. A single-serve size does not establish protection, and acceptable shelf life should not be inferred from a generic film description.
