Which of the following is the most suitable flexible packaging laminate for dry fruits?
Which of the following is the most suitable flexible packaging laminate for dry fruits?
Show Hint
For dry fruits, always look for laminates with excellent moisture and oxygen barriers; BOPP/LDPE is industry standard due to barrier properties and cost-effectiveness.
Updated On: Aug 27, 2025
- PET/LDPE
- PS/LDPE
- BOPP/LDPE
- Nylon/LDPE

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Packaging requirements for dry fruits.
Dry fruits require packaging that ensures: - Good moisture barrier (to avoid sogginess).
- Oxygen barrier (to prevent rancidity).
- Strength and sealability.
- Cost-effectiveness for flexible pouches.
Step 2: Compare the given laminates.
- PET/LDPE: PET is strong and transparent, but has relatively higher water vapor transmission compared to BOPP.
- PS/LDPE: Polystyrene is brittle and unsuitable for flexible packaging.
- \(\mathbf{BOPP/LDPE:}\) BOPP (Biaxially Oriented Polypropylene) gives excellent moisture barrier and printability, while LDPE provides heat-seal strength. This is widely used for dry fruits.
- Nylon/LDPE: Nylon provides toughness, but its moisture barrier is poor compared to BOPP.
Step 3: Best choice.
Thus, the most suitable laminate is BOPP/LDPE.
Final Answer:
\[ \boxed{\text{BOPP/LDPE}} \]
