Is Polypropylene (PP) labels a synthetic labels ?

Polypropylene (PP) labels are synthetic labels.

Unlike paper labels, PP is manufactured from polypropylene plastic, making it part of the synthetic label family.

Here's a simple comparison:

Why is PP called a synthetic label?

The word synthetic means man-made using polymers (plastics) rather than natural materials like paper.

Since polypropylene is a thermoplastic polymer, PP labels are classified as synthetic labels.

Types of synthetic labels

PP is just one type of synthetic label. Others include:

• Polypropylene (PP) – the most common synthetic label for retail, logistics, food, and cosmetics.
• Polyethylene (PE) –    flexible labels for squeezable bottles and curved containers.
• Polyester (PET) –        high durability for industrial, asset tracking, and electronics labels.
• Polyimide (PI) –          extreme heat resistance for PCB and electronics manufacturing.
• PVC (Vinyl) –               outdoor signage and specialty applications (used less today than PP or PET).

Advantages of PP labels

• ✔ Waterproof
• ✔ Tear-resistant
• ✔ Good resistance to oils and many chemicals
• ✔ Excellent print quality
• ✔ Available in white, clear, silver, matte, and glossy finishes
• ✔ Suitable for thermal transfer printing with the correct ribbon

Are all synthetic labels PP?

No.

All PP labels are synthetic, but not all synthetic labels are PP. Synthetic labels can also be made from PET, PE, PVC, polyimide, and other plastic-based materials.

Simple way to explain it

Think of it like this:

• Synthetic Label = The category (plastic-based labels)
• PP Label = One material within that category
• PET Label = Another material within the same category
• PE Label = Another material within the same category

So when someone says "synthetic label," they may be referring to PP, PET, PE, or another plastic label material. PP is simply the most widely used synthetic label material for general commercial applications.
