2026-08-11 · Huasheng Packaging Technical Content Review
根拠の範囲
The functional difference between clear PET/PE, metallized PET laminates and aluminum-foil laminates, plus the evidence needed before selecting a structure.
適用範囲と限界
No structure is prescribed for a specific food or shelf life. Grade, thickness, adhesive, printing, seals, conversion damage and test conditions can change the result.
要点
- VMPET is a metallized polymer film, not an aluminum-foil layer.
- Compare OTR and WVTR only under stated and comparable methods and conditions.
- Approve the complete converted laminate and finished pack, not a layer name alone.

| Metallized PET and aluminum foil are distinct barrier layers and should not be quoted or specified as equivalent. | direct | [1] | The cited comparison does not establish a universal ranking for every laminate or product. |
| OTR and WVTR comparisons require named methods, specimens and test conditions. | direct | [2], [3] | No target value is assigned to a specific food. |

Aluminum-foil and metallized-PET laminates are distinct structures whose barrier behavior must be compared as complete laminates - ASTM D3985-24: Oxygen Gas Transmission Rate Through Plastic Film and Sheeting Using a Coulometric Sensor · ASTM International · standard
OTR is measured for a defined specimen under a named method and agreed test conditions - ASTM F1249-25: Water Vapor Transmission Rate Through Plastic Film and Sheeting Using a Modulated Infrared Sensor · ASTM International · standard
WVTR applies to defined flexible barrier specimens and stated test conditions
よくある質問
Which is better, PET/PE, PET/VMPET/PE or PET/AL/PE?
There is no single best structure for all products. PET/PE is often used for general packaging needs with basic moisture protection. PET/VMPET/PE provides metallic appearance and improved barrier. PET/AL/PE is considered for stronger barrier requirements. The right choice depends on your product type, shelf life, storage conditions and cost expectations.
Is VMPET the same as aluminum foil?
No. VMPET is metallized PET film, while AL is a real aluminum foil layer. They may look similar in some cases but have different barrier performance and cost levels. VMPET should not be considered a direct replacement for aluminum foil.
Can PET/PE be used for coffee packaging?
It depends on shelf life and aroma protection requirements. Many coffee projects require PET/VMPET/PE or PET/AL/PE for better barrier performance. PET/PE alone may not provide enough aroma and oxygen barrier for coffee products.
Is PET/AL/PE always required for high barrier packaging?
Not always. PET/AL/PE is often reviewed for stronger barrier needs, but PET/VMPET/PE may be suitable for many dry food and snack applications depending on shelf life and storage conditions. We can help review what is appropriate for your specific product.
Can the same pouch type use different material structures?
Yes. A stand up pouch, flat bottom pouch or three side seal pouch can use PET/PE, PET/VMPET/PE, PET/AL/PE or other structures depending on product requirements. The pouch type determines the format, while the material structure determines the barrier and sealing performance.
What should I send before requesting a quotation?
Please send your product type, size, bag type, quantity, material requirement (if known), shelf life target, printing colors, artwork file and target market. A sample photo is also helpful for reference.
