Confused between BOPP and VMPET laminated pouches? We explain their barrier, appearance, usage and price to help you pick the right custom packaging bag.

BOPP and VMPET are two of the most widely used films for custom laminated flexible packaging. Many buyers from South America, North America and other regions often ask us which material is better for their products. As a professional flexible packaging manufacturer based in Foshan, China, Dongju Packaging will break down the differences simply for you.

What is BOPP?

BOPP stands for Biaxially Oriented Polypropylene.

Features: Clear, transparent, glossy, good printing effect.
Barrier property: Low moisture & oxygen barrier. It cannot block light.
Best for: Products that do not need light protection, such as candies, dried fruits, rice, beans, transparent window pouches.
Pros: Lower cost, high definition printing, customers can see the goods inside directly.
Cons: Not suitable for light-sensitive items, cannot extend shelf life for long-term storage.

What is VMPET?

VMPET is metallized PET film, also known as aluminized film. A thin layer of aluminum is vacuum-coated on the PET substrate.

Features: Silver metallic look, opaque.
Barrier property: Excellent barrier against oxygen, moisture and light.
Best for: Nuts, coffee, tea, spices, pet food, snacks, products that need anti-oxidation and moisture-proof storage.
Pros: Great shelf-life extension, good aroma retention, premium metallic appearance.
Cons: Not transparent, the cost is higher than normal BOPP film.

Common Composite Structure We Make

We usually combine them with PE for sealing:

BOPP + PE: Cheap transparent bags, good for dry grain, rice.
BOPP + VMPET + PE: The most popular structure. It has printing layer + metallized barrier + heat seal layer. This is the hot-selling laminated pouch for snacks and pet food.

How to make your final choice?

✅ Choose BOPP related bags if:You want customers to view your product, your goods are not easy to oxidize, and you control the budget.

✅ Choose VMPET laminated bags if:Your product is sensitive to light, air or moisture, and you need longer shelf life.

Note: If you need ultra-high barrier for essential oil, chemical powder, we also offer aluminum foil (AL) composite bags.
