よくある質問
What machine data is required for packaging roll film?
Provide the machine type and model, pack style, web width, repeat, core, maximum roll size, unwind orientation, eye-mark and sensor details, speed, seal method and an approved reference roll when available.
Is one COF value suitable for every packing machine?
No. COF interacts with the web path, forming surfaces, drive system, tension, product contamination and speed. Confirm it against the actual line or a proven reference film.
How should roll film unwind direction be confirmed?
Use an orientation drawing showing the printed face, leading edge, web travel and eye-mark sensor side. Do not rely only on a numbered unwind convention because numbering can vary.
What should an eye-mark specification include?
Confirm the mark size, color or contrast, pitch, distance from the web edge, sensor side and relationship to the cut position. The sensor type and artwork repeat also matter.
Can Huasheng Packaging guarantee film will run on my machine?
Compatibility is reviewed from the supplied specification and reference material, but final confirmation requires a controlled trial on the buyer’s actual machine, product and operating settings.
What should I record during a roll film machine trial?
Record the roll lot, machine, speed, tension, seal settings, tracking, registration, cut position, accepted and failed packs, start-up waste and any setting changes.
Can the film be sent directly to a co-manufacturer in China?
Yes, the technical specification can be coordinated with the designated co-manufacturer. The brand owner, co-manufacturer and packaging supplier should approve the same revision and define responsibility for artwork, machine data and trial acceptance.
