Product Description
Designed for medium‑weight vertical form‑fill‑seal (VFFS) and horizontal form‑fill‑seal (HFFS) packaging lines, this 45 g/m² cellophane (model RCM‑MK‑450) offers excellent balance between strength, stiffness, and transparency. With a thickness of 30 μm and tensile strength MD of 64 N/15mm, it reliably contains snacks, cereals, candies, and dried fruits while allowing full product visibility. The film is heat‑sealable (120‑160°C) and fully biodegradable via the NMMO solvent process.

Produced via the NMMO (Lyocell) solvent process: dissolving‑grade wood pulp is directly mixed with aqueous NMMO, dehydrated under vacuum at 85‑95°C to form a homogeneous cellulose solution (concentration 10‑15%). The solution is extruded through a slit die, passes a 5‑10 cm air gap, then coagulates in a cold water bath. The regenerated film is washed, dried at 80‑100°C, and rewound. Solvent recovery >98% ensures minimal environmental impact. The 45g grade achieves higher tensile strength by adjusting die gap and draw ratio, making it suitable for automated bag making.
