Custom Printed Back Seal Wrappers | Aluminum Foil Snack & Cookie Packaging Film - Linyi Gerun

Product Overview

Our back seal wrappers provide a sleek, continuous-wrap packaging solution ideal for high-speed snack and confectionery packaging lines. The back seal design creates a clean, professional appearance with the seal hidden on the rear of the package, maximizing front-facing brand real estate. Manufactured with precision rotogravure printing and reliable lamination technology, our back seal wrappers deliver consistent quality and eye-catching graphics that drive impulse purchases.

Key Features

• Clean Front-Facing Design: The back seal construction places the seal on the rear of the package, leaving the entire front surface available for impactful brand graphics and product imagery.
• High-Speed FFS Compatible: Engineered for reliable performance on horizontal flow-wrap and vertical form-fill-seal machines at production speeds up to 150 packs per minute.
• Aluminum Foil Barrier: Integrated foil layer provides excellent moisture and oxygen barrier for extended product shelf life and crisp texture preservation.
• 9-Color Rotogravure Printing: Vibrant, appetite-appealing graphics with precise registration and color consistency across production runs.
• Easy-Open Features: Laser-scored tear notches or easy-peel sealants for consumer-friendly opening.
