포장재 가이드: VMPET

Question 1

What is VMPET film?

Accepted Answer

VMPET (vacuum metallized PET) is PET film with a thin aluminum coating. It is not real aluminum foil. It provides metallic appearance and improved moisture and light barrier compared with non-metallized structures.

Question 2

When should VMPET be used in packaging?

Accepted Answer

VMPET is used when the product needs metallic appearance, better moisture protection or improved light barrier, such as coffee bags, snack packaging, pet food bags and dry food pouches.

Question 3

Is VMPET the same as aluminum foil?

Accepted Answer

No. VMPET is metallized PET film with a thin coating. Aluminum foil is a solid metal layer providing stronger barrier. VMPET is lighter, more economical, but provides lower barrier than aluminum foil.

Question 4

Can VMPET be used for high barrier packaging?

Accepted Answer

VMPET provides improved barrier compared with plain PET or BOPP, but for products requiring the strongest oxygen, moisture or aroma barrier, aluminum foil-based structures should be evaluated.

Question 5

What information is needed before quoting VMPET packaging?

Accepted Answer

Product type, shelf life requirement, barrier level needed, bag size or roll width, material structure, thickness, quantity, printing colors and artwork file.
