When sourcing or selling laminating film on Alibaba.com, buyers evaluate products across four fundamental attribute dimensions. Understanding these configurations is essential for Southeast Asian exporters to position their products correctly and communicate value to global B2B buyers.
Thickness is measured in mil (1 mil = 0.001 inch) or micron (1 mil ≈ 25.4 micron). Importantly, pouch thickness is specified per side—a 3 mil pouch creates a 6 mil total thickness after lamination. This distinction is critical when comparing supplier specifications and avoiding buyer disputes.
Material Type determines the film's core properties. The three dominant materials are PET (Polyester), PP (Polypropylene), and PE (Polyethylene), each with distinct advantages. PET excels in tensile strength (20,000-30,000 psi) and heat resistance (melting point 254°C), making it ideal for food packaging lids and industrial applications. PP offers superior clarity and gloss, preferred for retail packaging where product visibility matters. PE provides flexibility and impact resistance at lower cost, commonly used for shrink wraps and bulk packaging [2].
Surface Finish affects both aesthetics and functionality. Gloss finish preserves color vibrancy and creates a professional shine, but can produce glare under bright lighting. Matte finish reduces glare and provides a premium, soft-touch feel, but may dull printed colors. Satin finish offers a middle ground with moderate sheen. The choice often depends on end-use: menus and photo displays favor gloss, while ID cards and book covers often use matte [3].
Format refers to the physical form of the film. Pouches are pre-cut, sealed-on-three-sides pockets ideal for small-batch lamination (documents, photos, cards). Sheets are flat films used with roll laminators for larger formats. Rolls enable continuous, customized-size lamination for industrial production. Pouches dominate the SMB and office supply market, while rolls serve commercial printing and packaging facilities [4].
