PVC Shrink Film vs. Polyolefin Shrink Film

Shrink films have become an essential packaging material in various industries, playing a significant role in protecting, preserving, and enhancing product appearance. Two popular shrink film materials are PVC (Polyvinyl Chloride) and Polyolefin. Although both films serve a similar purpose, they possess unique characteristics, making them suitable for different applications. In this article, we will explore the properties, advantages, and disadvantages of PVC shrink film and polyolefin shrink film to help you make an informed decision when selecting the right packaging material for your product.

PVC Shrink Film


PVC heat shrinkable film is a plastic material made from polyvinyl chloride, a versatile polymer known for its clarity, high shrinkage ratio, and ease of use. The film is available in various thicknesses and sizes, making it a popular choice for a wide range of applications. It is known for its ability to conform tightly to the shape of the product, creating a tight seal and protecting the contents from external elements.




It’s a cost-effective option, especially for small businesses or those with a limited budget for packaging materials.


Clarity and Gloss

PVC shrink film offers excellent product visibility and a glossy finish, enhancing the aesthetic appeal of the packaged item.


High Shrinkage Ratio

With a high shrinkage ratio, PVC film can tightly wrap around various product shapes and sizes, providing a secure and neat packaging solution.


Ease of Use

PVC heat shrink film is easy to work with, as it can be used with manual, semi-automatic, or fully automatic shrink wrapping machines.



Environmental Concerns

PVC shrink film is not considered an eco-friendly option, as it releases harmful chemicals when burned and does not decompose easily.


Limited Barrier Properties

PVC film does not offer the same level of protection against moisture, gases, and odors as polyolefin shrink film.

Polyolefin Shrink Film


Polyolefin shrink film is a more modern packaging material made from a blend of polyethylene (PE) and polypropylene (PP) polymers. It offers excellent clarity, high tensile strength, and superior tear resistance. Polyolefin shrink film is available in a variety of gauges and sizes, making it suitable for a wide range of applications, including food packaging.



Superior Barrier Properties

Polyolefin shrink film provides excellent protection against moisture, gases, and odors, making it ideal for packaging perishable products.


Tear and Puncture Resistance

Due to its high tensile strength, polyolefin shrink film is less susceptible to tearing or puncturing, ensuring that the packaged products remain protected during handling and transportation.


Food Safety

Polyolefin shrink film is FDA-approved for direct food contact, making it a safe choice for food packaging applications.



Unlike PVC shrink film, polyolefin shrink film is more environmentally friendly as it does not release harmful chemicals when burned and can be recycled.



Higher Cost

Polyolefin shrink film is generally more expensive than PVC shrink film, which may be a concern for businesses on a tight budget.


Sealing Temperature

Polyolefin shrink film requires a higher sealing temperature than PVC, which may necessitate the use of specialized sealing equipment.

Choose Correct Shrink Packaging Film

Both PVC heat shrink wrap film and polyolefin shrink wrap shrink film offer unique benefits and drawbacks, making the choice between the two materials largely dependent on the specific requirements of your product and packaging process. PVC shrink film is an affordable and easy-to-use option that provides excellent clarity and a high shrinkage ratio. However, it has environmental concerns and limited barrier properties.

On the other hand, polyolefin shrink film offers superior barrier properties, tear resistance, and food safety, making it a suitable choice for perishable products and environmentally conscious businesses. However, it comes with a higher price tag and requires specialized equipment for sealing.

In conclusion, when selecting the appropriate shrink film for your product, consider factors such as budget, environmental impact, product protection, and ease of use to ensure that you choose the right material for your specific packaging needs.
