When selecting PVC printing film, it is necessary to comprehensively consider factors such as the application scenario, performance requirements, environmental protection requirements, and budget.
Clarify Usage and Classification
PVC printing films can be divided into the following categories based on function, and different applications correspond to different selection logic:
Decoration/Lamination: Used for laminating surfaces of furniture, doors and windows, cabinets (as mentioned in 1). Common thickness is 0.3–0.7mm. Attention should be paid to adhesion, fold resistance, color stability.
Protection Film: Used for surface protection of electronic screens, metal panels, glass, etc., divided into adhesive type (PVC protective film) and electrostatic type (non-adhesive). Selection is based on surface characteristics.
Label/Shrink Film: Used for beverage bottles, daily chemical product packaging. Shrinkage rate, environmental friendliness, and printability need to be considered.
Car Stickers/Signs: Used for vehicles or outdoor signs, emphasizing weather resistance, UV resistance, and flexibility.
Card Lamination: Used for IC cards, membership cards, etc., requiring lamination temperature adaptation (110–150°C) and peel strength ≥5N/cm.
Key Selection Parameters
Thickness
Decoration Lamination: 0.3–0.7mm
Protection Film: 0.03–0.25mm (electrostatic films are thinner, protective films can be thicker)
Card Lamination: commonly 0.08mm
Temperature Range
Ordinary PVC printing film: -20°C to 70°C
Electrostatic films have a lower upper limit (about 50°C); for outdoor or high-temperature environments, it is recommended to choose adhesive type.
Environmental Friendliness
Soft PVC contains plasticizers which may leach over long-term use; for food contact or high-end daily chemical products, POF/PE is recommended first. If PVC must be used, it must meet environmental standards like RoHS and REACH (some manufacturers have optimized formulas to reduce harmful substance release).
Adhesion and Back Adhesive
Low tack (≤50g/25mm): suitable for delicate glossy surfaces such as painted surfaces and glass;
Medium to high tack (≥150g/25mm): suitable for rough surfaces or outdoor scenarios, such as stone and metal panels;
The type of back adhesive affects the risk of residue; high-quality products should leave no residue when peeled off.
Printability
Surfaces need to be treated with corona or coated with primer to improve ink adhesion;
For bright colors and clear patterns, choose PVC films specifically for gravure or flexographic printing.
