PET VS PP VS Synthetic Paper: How to Choose the Right Self-Adhesive Face Stock Material

PET vs PP vs Synthetic Paper: How to Choose the Right Self-Adhesive Face Stock Material

Face stock material determines the label’s hardness, transparency, waterproof performance, printing effect and service life. Most label converters face confusion when selecting PET, PP, and synthetic paper jumbo rolls. This guide helps you select the very suitable face stock for different industrial scenarios.

1. PET (Polyester) Film Material

PET film is a high-strength, transparent, tear-resistant face stock.

• Core advantages: High transparency, rigid texture, very good high-temperature resistance, no deformation, waterproof and oil-proof
• Printing performance: Compatible with UV digital inkjet, flexo, offset and laser printing
• Typical application: Transparent overlaminate film, electronic labels, high-temperature resistant labels, cosmetic packaging labels
• Matching adhesive: Water-based acrylic, solvent-based acrylic adhesive

2. PP (Polypropylene) Film Material

PP film is lightweight, flexible and cost-effective plastic face stock.

• Core advantages: Soft texture, good toughness, low cost, good waterproof performance
• Limitations: Poor high-temperature resistance compared with PET
• Typical application: Daily chemical labels, commodity barcode labels, general waterproof labels

3. PP Synthetic Paper Material

Synthetic paper is a plastic-based paper material with paper texture and plastic waterproof performance.

• Core advantages: very good waterproof, tear-proof, no powder falling, strong color printing reduction
• Super performance: Ultra-low temperature resistance, suitable for frozen environment
• Typical application: Frozen food labels, cold chain logistics labels, seafood packaging labels

Quick Selection Rule

Use rigid transparent PET film for high-grade packaging and over-lamination; choose flexible PP film for daily general labels; adopt synthetic paper for waterproof, cold-resistant and high-printing-demand scenarios.
