포장재 가이드: Aluminum Foil

Question 1

What is aluminum foil laminated packaging?

Accepted Answer

Aluminum foil laminated packaging uses a thin aluminum foil layer as part of a multi-layer flexible packaging structure. The foil provides strong barrier against light, oxygen, moisture and aroma, commonly used for coffee, powder, retort and long shelf-life food products.

Question 2

When should aluminum foil be used in flexible packaging?

Accepted Answer

Aluminum foil should be considered when the product requires maximum protection from light, oxygen, moisture or aroma loss, especially for coffee, sensitive powders, retort products and products with extended shelf life requirements.

Question 3

Is aluminum foil packaging more expensive?

Accepted Answer

Yes. Aluminum foil structures typically cost more than VMPET or non-foil alternatives due to material cost and processing considerations. The higher cost should be weighed against the barrier protection required.

Question 4

Can aluminum foil packaging be used for retort?

Accepted Answer

Aluminum foil can be part of a retort pouch structure, but the sealing layer and lamination must be confirmed for the exact sterilization temperature and time. Not all foil laminates are suitable for retort without technical review.

Question 5

What information is needed before quoting aluminum foil packaging?

Accepted Answer

Product type, shelf life target, barrier requirements, retort or non-retort, bag size, material structure, thickness, quantity, printing colors, artwork, target market and China OEM or domestic warehouse handover requirement if applicable.
