Crosslinked vs Non-Crosslinked Shrink Film: A Comprehensive Comparison

Shrink film is a versatile and widely used material for packaging products, providing a tight and secure wrap around the product. However, not all shrink films are created equal, and choosing the right type of shrink film for your packaging needs is crucial. In this blog post, we will compare crosslinked shrink film to non-crosslinked shrink film and highlight the key differences between the two.

Crosslinked Shrink Film:

1. Crosslinked shrink film is made by chemically bonding the polymer molecules together, creating a more robust and durable film.

2. This type of shrink film has a higher shrink force, meaning it provides a tighter and more secure wrap around the product.

3. Crosslinked shrink film is more heat-resistant, making it ideal for high-speed packaging operations and applications where high temperatures are present.

4. It has a higher puncture resistance, providing added protection to the product during transportation and storage.

5. Crosslinked shrink film is more resistant to tearing and provides better overall product protection compared to non-crosslinked shrink film.

Non-Crosslinked Shrink Film:

1. Non-crosslinked shrink film is made by combining polymer resins, but the molecules are not chemically bonded together.

2. This type of shrink film has a lower shrink force, making it less suitable for applications that require a tight and secure wrap around the product.

3. Non-crosslinked shrink film is more flexible and has a lower melting point, making it ideal for applications where the product requires a more delicate touch.

4. It is less expensive compared to crosslinked shrink film, making it a cost-effective option for businesses with a limited budget.

5. Non-crosslinked shrink film is more suitable for applications that require a soft and flexible packaging material, such as packaging fresh produce.

In conclusion, both crosslinked and non-crosslinked shrink films have their own unique features and advantages. The choice between the two ultimately comes down to the specific needs of the application. If a tight and secure wrap around the product is required, then crosslinked shrink film is the ideal choice. On the other hand, if a more flexible and cost-effective option is needed, then non-crosslinked shrink film is the better option. It is important to carefully consider the specific needs of your packaging application before making a decision.
