When it comes to premium chocolate packaging, visual appeal and functionality must go hand-in-hand. One material that continues to gain popularity in the food packaging industry — especially for luxury chocolate trays and gift boxes — is the PET golden sheet. But what exactly is PET golden sheet, and why is it such a preferred choice in thermoformed chocolate packaging?
Let’s explore.
What Is PET Golden Sheet?
PET golden sheet refers to a polyethylene terephthalate (PET) plastic sheet that has been laminated or coated with a golden metallic layer. This golden finish gives it a premium, glossy appearance that enhances product value, especially in confectionery packaging.
It is commonly supplied in roll or sheet form, designed specifically for thermoforming applications such as forming cavities for chocolate, pralines, or truffles.
PET itself is a widely used, FDA-compliant plastic known for its clarity, rigidity, and excellent barrier properties. When combined with a metallic gold finish, it offers both aesthetics and performance.
Why Use PET Golden Sheet for Chocolate Packaging?
- Luxury Appearance
The shiny gold surface makes chocolate products appear more upscale and festive, perfect for gifting occasions. - Food Safety
PET is safe for direct food contact and complies with FDA and EU food-grade regulations. - Excellent Thermoformability
PET golden sheet maintains high precision when molded into complex shapes, ideal for multi-cavity chocolate trays. - Durability
PET sheets are impact-resistant and don’t crack or deform easily during transportation. - Barrier Properties
PET provides a protective layer that helps preserve the freshness and quality of chocolate by offering moisture and oxygen resistance. - Custom Options
Available in various thicknesses (usually 0.25mm–0.8mm), gloss levels, and embossing patterns. It can also be combined with other layers (e.g., EVA or PE) for sealing.
Common Applications
- Chocolate tray inserts inside boxes
- Thermoformed blister packs for premium confectionery
- Gift packaging for seasonal collections (Valentine’s Day, Christmas)
- Bakery and dessert tray liners
