Manufacturing of plastic shrink film


Plastic shrink film is usually composed of PE material, which is polyethylene. This material has high strength and can be melted into pellets during the manufacturing process. The pellets are then extruded into a thin film and other substances can be added according to the requirements, such as antioxidants, UV absorbers, and pigments, to improve its additional characteristics. Therefore, there are many different types of shrink film on the market, such as UV-resistant shrink film, radiation-resistant shrink film, pizza shrink film, and more.


Characteristics of plastic shrink film


Plastic shrink film generally has the following characteristics: transparency, abrasion resistance, shrinkage, moisture-proof, dust-proof, and UV resistance. Here are more detailed descriptions of each characteristic:


- Transparency: Plastic shrink film is a transparent film that allows clear visibility of the contents inside the packaging.


- Abrasion resistance: Plastic shrink film has high abrasion and tear resistance, providing excellent protection for the packaged product.


- Shrinkage: Plastic shrink film can be heated to shrink and tightly wrap around the packaged product, forming a tight outer shell.


- Moisture-proof: Plastic shrink film can prevent the packaged product from getting damp and maintain its quality.


- Dust-proof: Plastic shrink film can prevent the packaged product from being affected by dust and other pollutants.


- UV resistance: Plastic shrink film can prevent the packaged product from being affected by UV rays, extending its lifespan.
