Although both materials offer excellent barriers, there is a key difference:

• ALOxPET is a completely aluminum-free, transparent coating. It provides extremely high protection against oxygen and moisture while keeping your product visible.
• MET-PET is a metallized polyester layer. It has a silvery appearance and provides a very strong barrier but contains a microscopic layer of aluminum particles. For a 100% metal-free solution, ALOxPET is the best choice.

In our multi-layer pouches, these materials serve different roles. PET provides strength, gloss, and a barrier against external influences. PE (Polyethylene) is on the inside and serves as the 'seal layer.' It ensures the bag can be easily and airtightly heat-sealed, while also providing flexibility and moisture resistance.

Absolutely. By using smart combinations of materials like PET, PE, and specialized coatings like ALOxPET, we create a laminate that is mechanically just as strong. Your packaging is tear-resistant and retains its shape, while the barrier properties guarantee the freshness of products like coffee or snacks.

Yes, that is one of the biggest advantages! Traditional aluminum foil is difficult to separate from plastic. Our aluminum-free solutions—especially when constructed as mono-materials (e.g., combinations of only PE types or PET)—are much easier to process in modern recycling streams. This makes your packaging much more future-proof.

Certainly. Materials like PET and specifically ALOxPET are known for their excellent aroma-tightness. They keep the aroma of your product (such as spices or pet food) inside the bag and prevent outside odors from affecting the quality.
