In the film packaging industry, your role in selecting the right material for your product is crucial. Your choice ensures the safety and durability of the product. Among the plethora of packaging film materials available, PET-G and PVC shrink films offer many advantages. But what is the difference between these two shrink films?
Let's understand!
PET-G Film
- Polyethylene Terephthalate Glycol, popularly known as PET-G, is renowned for its superb pliability.
- The global demand for PET-G is expected to reach 58.47 billion by 2031.
PVC Films
- Polyvinyl Chloride, popularly known as PVC, is a kind of film, most adaptable and extensively used shrink film that contains 57% chlorine and 43% carbon.
- The global demand for PVC is expected to reach USD 75.15 billion by 2031.
Let's understand the difference between high-shrink PET-G Films and PVC films.
PET-G vs. PVC
Here are some major differences between PET-G and PVC film.
A. Clarity & Appearance
PET-G Film
- Exceptional clarity and gloss
- High-quality, transparent packaging
- Aesthetic appeal on store shelves
- Do not brittle over time
- Maintains appearance even after extended periods
PVC Film
- Good clarity, but not as crystal clear as PET-G
- Glossy and smooth finish after heat shrinking
- Attractive product appearance
• Brittle over time
B. Shrinkage
PET-G Film
- Excellent shrinkage property
- Shrinks at a lower temperature and with less force
- Controlled and consistent shrinkage
- Suitable for heat-sensitive products or those that require more gentle shrinkage
PVC Shrink Film
- High shrinkage property but has lower shrinkage compared to PET-G
- Lower cost
C. Heat Resistance
PET-G Films
- Excellent heat-resistant films
- Higher melting point than PVC
PVC Films
- Good heat resistance
- Lower melting point than PVC film
D. Environmental Considerations
PET-G Films
- Recyclable
- Do not emit harmful gases during the heat-shrinking process.
PVC Films
- Not as environmentally friendly as PET-G film
- Release non-environment friendly gases on heating
- Not easily recyclable
E. Product Application
PET-G Film
- Packaging products that require excellent product visibility. E.g., beverages, personal care items, and food products.
PVC Film
- Used for packaging various other products. E.g., Food items, electronics, pharmaceuticals, and promotional materials.
Both PET-G and PVC have unique advantages. But PET-G offers better clarity, dimensional stability, controlled shrinkage, and environmental stability.
