IntroductionPVC shrink film is a popular packaging material that has been used for decades. It is a type of thermoplastic film that shrinks when heat is applied, making it ideal for product packaging.

What is POF shrink film? Where to use and how to use it? This post introduces the definition, characteristics and application method of POF shrink film.

There are many shrink films currently used, such as polyolefin heat shrinkable film (POF), polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), followed by polyvinylidene chloride (PVDC), polyester ( PET), polystyrene (EPS), ethylene-vinyl acetate (EVA).

POF shrink film can be used for insulation packaging of electrical appliances and electronic components (such as the outer packaging of dry batteries); packaging of general items and food contact packaging, etc.

Differences in physical properties between POF shrink film and PE and PVC shrink film:POF is thin and tough, uniform thickness, good moisture resistance, soft texture, high tensile strength, high tear resistance, adjustable shrinkage, good friction resistance;

Shrink packaging(shrink wrap) is a packaging method in which products or packages are wrapped with shrink film, and then heated to shrink the film to tightly wrap products or packages. Shrink wrap is a promising packaging technology widely used in sales and transport packaging.

Shrink film is a common packaging film,Shrink film can be divided into four categories according to different raw materials and processes (PVC shrink film, PE shrink film, POF shrink film and other shrink films).

POF shrink film​, also known as BOPE shrink film (biaxially oriented polyethylene film), is a shrink film made of polyolefin biaxially stretched by double bubble method. Compared with traditional polyethylene blown film shrink film, POF shrink film has excellent mechanical properties, good transparency and uniform longitudinal and transverse shrinkage. Generally speaking, POF shrink film is divided into two categories: ordinary POF and cross-linked POF.

Because of its many advantages, POF shrink film has good development and application in the market. However, the products produced by some manufacturers may have poor shrinkage.So what are the factors
