Recessed heater surfaces matched to mold cavities improve film stretching uniformity, producing stable thermoformed pouches with less material.
Surface depressions and controlled heating help thermoform detergent films with uniform thickness and stronger portion units.
A depression-structured heating device guides deep-drawn packaging film toward uniform thickness and stronger detergent pouches.
A recessed heating surface creates localized heat zones for more uniform packaging film thickness during deep drawing.
This case uses heated-surface depressions and vacuum forming to improve thickness uniformity in multi-chamber detergent pouches.
