What Is A POF Shrink Film? How Does It Work?

“POF shrink film”, or “Polyolefin shrink film”, has been crafted out of polyolefin polymers, which offer superb transparency, strength, and flexibility” and elicits a high tone. Unlike PVC shrink film which is toxic to the environment and potentially dangerous, POF is safe at use where the charges can contact food.

It functions by tightly packing the items within the clear, thin sheet of film after heating with a heat gun or in a shrink tunnel. This heat application causes the film to contract tightly around the product, creating a secure, protective seal that is both tamper-evident and visually appealing. Heating of the glue joint of the film causes close-refitting around the product resulting in a tamper-evident, visually attractive enduring seal.

It is not only the process that makes the product’s shelf appeal greater but also offers protection against dust, moisture, and more importantly other external conditions, hence making POF shrink film a good choice for packaging a wide variety of products.

Features Of POF Shrink Film For Product Packaging You Must Consider Before Buying

In the case of choosing POF (Polyolefin) shrink film for product packaging, there exist a few crucial features to determine the film’s performance and efficiency. POF shrink film is known to provide great contrast, quality, and stretch, which qualifies it as being the preferred packaging option for many users.

Let’s delve into these essential attributes:

Shrink Force:

This refers to the amount of force that the shrink film exerts on the product as it shrinks during the heat-sealing process. It’s crucial to choose a film with an appropriate shrink force for your product to avoid damage. Delicate items may require a film with a lower shrink force to prevent compression or distortion.

Shrink Orientation:

POF shrink film can shrink in two directions: bidirectional (balanced shrink) or unidirectional. The shrink orientation affects how the film conforms to the shape of the product. For uniform products, a balanced shrink may be ideal as it provides an even shrinkage around the entire item, whereas unidirectional shrink may be more suited to products that benefit from tighter wrapping in a specific direction.

Shrink Percentages:

This feature indicates how much the film can shrink in relation to its original size, typically expressed in two dimensions. High shrinkage percentages mean the film can conform closely to irregular shapes, ensuring a tight, secure, and attractive package. The right shrink percentage depends on the shape and size variability of the products being packaged.

Moisture Vapor Transmission Rate (MVTR):

The MVTR is especially important for food packaging. It measures the film’s ability to allow moisture vapor to pass through. A low MVTR is essential for products that need to retain moisture, such as fresh produce, to ensure they do not dry out. Conversely, products prone to spoilage from excess moisture may require a film with a higher MVTR.

Resistance to Puncture:

Depending on the nature of the products being packaged, the shrink film’s resistance to punctures can be a significant factor. Products with sharp edges or points require a film with high puncture resistance to maintain integrity during handling, transportation, and display.

Antifog Properties:

Concerning products that are preset to refrigeration or temperature convolution that results in condensation formations, it is important to go for a self-slack of Pov. The role of these films is to keep the package as transparent as it is even when there is a touch of moisture thus you are sure that the product being packaged remains attractive to the consumers. This has the biggest effect on fresh foods and other perishable items because their visual presentation comes into the way of making purchase decisions.

As for POF (Polyolefin) shrink film, customers have the option to enjoy several advantages such as superb clarity and gloss; the presentation of the products and the visibility of the contents are thus enhanced. The absolute value of its durability and puncture resistance gives its goods the resistance they require during safe handling and transportation processes. Flexible POF film is applied in shop shelves, smoking detection, food monitoring, emergency evacuation, and manufacturing; low shrinkage temperature minimizes energy consumption and the risk of damage to thermal parts. Also, it is food-safe, recyclable, and low on emission during the sealing process with no releasing of any dangerous chemicals as its grabbing ability for important compounds and nutrients is similar to nature. This is why it’s a green and safe choice for many packaging needs.
