Aroma-Lock & Low-Heat Overwrapping for Tea, Chocolate & Rigid Gift Boxes
Protect volatile tea botanicals and heat-sensitive praline chocolates with low-temperature contact-plate 3D BOPP and biodegradable cellulose overwrappers.
Preserving Volatile Aromas and Cocoa Butter Without Tunnel Heat
Specialty loose-leaf teas lose top-note aromatics rapidly when exposed to ambient humidity, while boxed chocolate pralines suffer grey fat-bloom if warmed above 28–30 °C inside a shrink tunnel. Built on carton overwrapping applications and BOPP and cellophane film specs, 3D contact-plate overwrappers touch only the narrow film overlap for fractions of a second—keeping box interiors at room temperature.
Wide-format models (CW-400 / FTBT-480 class) accommodate flat chocolate assortment boxes up to 300–320 mm long at 30–80 boxes/min.

| Assorted Chocolate Praline Box | 22–25 μm low-initiation BOPP | 100–115 °C | Zero internal warming; crisp luxury corners |

Compare shrink tunnels directly in overwrapping vs shrink and flow wrap.
3D Overwrapping Engineering Notes
- Gentle Low-Acceleration Pusher: S-curve servo pusher motion prevents delicate chocolate truffles or biscuits from shifting out of thermoformed tray cavities inside the box.
- Biodegradable Cellulose Option: Eco-positioned tea and soap brands can run genuine wood-pulp cellulose film on properly tensioned overwrappers.
- Seasonal Ribbon & Sticker Compatibility: Flat glass-smooth BOPP faces accept promotional foil seals and holiday belly-bands effortlessly.
