Quality: Film Type: Shrink films are available in different types based on the polymer used. The most common types include polyolefin shrink film, polyethylene shrink film, and PVC shrink film. Each type has its own characteristics in terms of clarity, shrinkage properties, and suitability for different applications.

Thickness: Shrink film is available in various thicknesses, typically measured in micrometers (μm). Thicker films offer higher strength and puncture resistance, while thinner films provide cost savings and flexibility.

Clarity: Shrink film can have varying levels of clarity, ranging from transparent to opaque. Clear films allow for easy visibility of packaged products, while opaque films provide privacy or concealment.

Performance: Shrinkage Properties: Shrink film is designed to shrink uniformly and tightly around the product when heat is applied. The shrinkage properties of the film determine how well it conforms to the shape of the product and provides a secure wrap.

Shrink Temperature: Different shrink films have specific shrink temperature ranges. It is essential to use the appropriate heat source, such as a heat tunnel or heat gun, to achieve optimal shrinkage without damaging the product.

Puncture Resistance: Shrink film should have sufficient puncture resistance to protect the packaged product from sharp edges or rough handling during transit.
