PET (Polyethylene Terephthalate) in flexible packaging
What is PET?
PET (polyethylene terephthalate) is a thermoplastic polyester with high rigidity, transparency, and thermal resistance.
In flexible packaging, it is commonly used as an outer layer in laminated structures, as it provides stability, protection, and excellent visual presentation.
Applications in Flexible Packaging
Laminates for products requiring high barrier or sterilization.
Packaging for snacks, coffee, prepared foods, and chemical products.
Wrappers for gourmet or high-value products.
Ideal for multilayer structures in hot-fill or pasteurization processes.
Advantages of PET
High mechanical resistance, ideal against punctures and tears.
Thermal stability, suitable for processes such as hot filling.
Excellent oxygen and gas barrier, extending the freshness and shelf life of the product.
Available in transparent or metallized finishes, for different technical and aesthetic needs.
Excellent lamination adhesion, facilitating its combination with other materials such as PE or BOPP. High mechanical resistance, ideal against punctures and tears.
