PVC (Polyvinyl Chloride) shrink film has long been a popular choice for labeling and packaging due to its low cost and wide availability. However, with increasing demand for sustainable, safe, and premium packaging, many brands are now shifting from PVC to PETG (Polyethylene Terephthalate Glycol-modified) shrink film.
PETG is halogen-free, while PVC contains chlorine that can release harmful byproducts during disposal or incineration.
PETG can be more easily integrated into PET recycling streams, making it a better fit for sustainable packaging strategies.
PETG offers up to 70–80% shrinkage, compared to PVC’s 60%, allowing it to tightly conform to complex container shapes.
This makes PETG ideal for modern packaging designs that require full-body labels.
PETG shrink film has higher clarity and gloss, giving packaging a premium look.
It supports gravure, flexo, and digital printing, enabling high-resolution graphics and vibrant colors.
PETG Bidirectional Shrink Film
PETG is tougher and more impact-resistant than PVC, reducing cracking and damage during application and transportation.
It also withstands moisture, oils, and chemicals better, ensuring label integrity.
Many multinational brands and industries are phasing out PVC due to regulatory and environmental concerns.
PETG has become the preferred alternative for companies seeking sustainable and safe labeling materials.
| Feature | PETG Shrink Film | PVC Shrink Film |
|---|---|---|
| Shrinkage Rate | Up to 70–80%, excellent for complex shapes | Up to 60%, limited for irregular containers |
| Clarity & Gloss | High transparency, glossy, premium appearance | Good clarity but may yellow or haze over time |
| Printability | Supports gravure, flexo, digital; vibrant colors | Printable but less detail and limited effects |
| Durability | Strong, tear-resistant, impact-resistant | More fragile, prone to cracking or tearing |
| Moisture & Chemical Resistance | Excellent resistance to oils, water, and chemicals | Moderate, can weaken in harsh conditions |
| Eco-Friendliness | Halogen-free, recyclable in PET streams | Contains chlorine, releases harmful byproducts |
| Market Trend | Preferred by global brands for sustainability | Gradually being phased out in many industries |
| Cost | Slightly higher, but better long-term value | Lowest cost, widely available |
While PVC shrink film remains a low-cost option, PETG shrink film provides significant advantages in sustainability, performance, and branding appeal. For companies focused on eco-friendly packaging and premium market positioning, PETG is the best alternative to PVC shrink film.
