Film en rouleau pour machines d'emballage automatiques : matériaux et compatibilité
Guide du film imprimé pour machines VFFS/HFFS. Matériaux, traitement de surface, repérage et propriétés de thermoscellage.
Why Roll Film Must Match the Machine
Roll film must match the machine film carriage width, unwind direction, sealing jaw design, eye mark sensor and sealing temperature window. Even a good laminate can run poorly if the specification does not fit the line.
Data Buyers Should Confirm
Buyers should confirm product type, filling weight, roll width, core size, winding direction, repeat length, print registration and barrier level. For biscuit and dry food projects, these details are operational requirements, not just shipping data.
Common Material Starting Points
BOPP/CPP is common for light dry snacks and biscuit flow packs. PET/PE suits general food and powder. PET/VMPET/PE improves barrier for moisture-sensitive products, while PET/AL/PE provides stronger protection for aroma-sensitive products.
