Flow Wrap Packaging
Flow Wrap Packaging — real performance on high-speed lines
Flow wrap packaging is the format that wins where speed, repeatability and low cost per unit matter most. With the right film structure, COF and sealing parameters, your line starts faster and the pack front stays clean and fully consistent with your brand guidelines.
What you gain with flow wrap packaging:
stable output at high machine speeds
low unit cost for large volumes
reliable seals even with variable product weight
large communication area (front + back), optional window and easy-open feature
Doypack with zipper vs. flow wrap — when convenience matters
Doypack pouches with zipper are chosen when reclosability, shelf presence and premium feel are key. They often compete with flow wrap — but the function and user expectation are different.
Quick comparison: doypack vs. flow wrap
Cost & efficiency
flow wrap – fastest and most cost-effective
doypack – higher cost, but with re-seal functionality
Consumer use
doypack – convenient reclosure (granola, pet food, powders)
flow wrap – easy-open remember
Shelf appearance
Both offer strong branding; doypack enables premium finishes such as:
matte, soft-touch, large windows.
Barrier performance
Defined by the laminate structure (metallised BOPP, coated films, PET) — achievable in both formats.
Line stability in practice — COF, SIT and hot-tack
Regardless of the format:
COF is tailored to your film path to reduce micro-stoppages
Low SIT & high hot-tack (typically via CPP sealant layer) ensure fast sealing and seal strength during product drop
Consistent thickness & winding quality mean less start-up waste
Flow wrap packaging — implementation step by step
Technical brief – product, barrier (OTR/WVTR), speed, visual expectations
Film structure selection – recyclable mono PP or high-barrier laminate, functional coatings
Prepress – no-print areas, white ink, matte/gloss contrast, proof approval
Pilot run – testing on your machine, COF/SIT/hot-tack fine-tuning
Full production – repeatable colour, full traceability, stable deliveries
Summary — flow wrap packaging vs. doypack with zipper
Need maximum speed and lowest cost per pack? Choose flow wrap packaging.
Need reclosure and premium shelf impact? Choose doypack with zipper.
We design the material for your product and your line — from recyclable mono-PP structures, through high-barrier laminates, to HD flexo printing up to 8 colours.
We set COF, SIT and hot-tack, run pilot trials and deliver fully repeatable production.
