In thermoforming packaging, PET Lamination PE usually includes two fundamentally different solutions: 1. PET Sheet with PE Protective Film (Peelable)；2. PET + PE Laminated Structure (Functional Lamination / Co-extrusion)
In food and medical thermoforming markets, the term “PET Lamination PE” is often used broadly. In actual production and export practice, it refers to two fundamentally different material structures, each serving a distinct purpose. Misunderstanding these structures frequently leads to incorrect material selection.
| Spesifikasi | Peelable film or permanent sealing layer | PET Sheet with PE Protective Film (Peelable) |
|---|---|---|
| Warna | Warna apa pun yang disesuaikan | Warna apa pun yang disesuaikan |
| Bahan | PET / R-PET / PE | PET / R-PET / PE |
| Perawatan Permukaan | Film PE yang dilaminasi | Film PE yang dilaminasi |
| Lebar | 250–1400 mm | 250–1400 mm |
| Ketebalan | 0.18–1.7 mm | 0.18–1.7 mm |
| PE Layer | 20 – 50 μm | 30 – 80 μm |
This structure consists of a standard APET or PETG sheet with a thin PE protective film applied to one or both sides. The PE layer is not intended for sealing or bonding; its sole function is surface protection.
The PE film is removed prior to forming. PET recycling streams remain unaffected as long as the film is separated correctly. This structure is considered a temporary protection solution, not a functional laminate.
In this structure, PE is permanently laminated or co-extruded with PET, forming a functional multi-layer sheet. The PE layer actively participates in heat sealing, barrier performance, and tactile properties.
As PET and PE belong to different polymer families, recycling depends on layer thickness ratio and local recycling infrastructure. In most export markets, these structures are used where functional performance outweighs mono-material requirements.
| Fitur | PET + PE Protective Film | PET + PE Laminated Layer |
|---|---|---|
| PE Function | Temporary surface protection | Permanent functional layer |
| Heat Sealing | Not applicable | Fully compatible |
| Peel Behavior | Manual peel-off before forming | Controlled peel strength after sealing |
| Daur ulang | High (after film removal) | Application-dependent |
