Historical Development Path
Early Adoption Phase
Initial reliance on simple single-layer polyethylene (PE) bags for dry goods and basic wrapping, with limited shelf-life and high vulnerability to environmental factors.
Industrialization Phase
The introduction of basic lamination and gravure printing, allowing for better branding and slightly improved barriers for snacks and frozen foods.
High-Barrier Innovation Phase
Current shift toward tri-laminate structures and retort technology, enabling sterilized packaging that replaces traditional metal cans for wet foods.
Future Technological Trajectory
1. Shift to Biodegradable Polymers
Growing regulatory pressure in Vietnam to reduce single-use plastics is driving the adoption of biodegradable shrink wrap bags for soap and food-grade compostable films.
2. Intelligent Barrier Integration
Integration of active packaging elements that can monitor freshness or absorb oxygen, further extending the shelf-life of exports.
3. Automation in Filling and Sealing
Transition from manual packing to high-speed FFS (Form-Fill-Seal) systems to increase production efficiency for large-scale manufacturers.
