Polyolefin (PO) film is a popular packaging material used in various industries, including food, pharmaceuticals, cosmetics, and more. Printed PO film is a type of PO film that is customized with graphics, logos, and branding to make the packaging more visually appealing and attractive. However, choosing the right printed PO film can be a daunting task, especially if you are not familiar with the various factors to consider. In this article, we will discuss how to choose the correct printed PO film, including the different types of PO film, product compatibility, thickness, clarity, strength and durability, print quality, environmental impact, and cost.

 

 

Polyolefin film is made from polymer materials such as polyethylene (PE) and polypropylene (PP). These materials are widely used in packaging because of their strength, durability, and flexibility. There are two types of polyolefin films: shrink and non-shrink.

 

Shrink Film

Shrink film is a type of polyolefin film that shrinks when exposed to heat. This property allows the film to conform tightly to the product being packaged, providing excellent protection against moisture, dust, and other environmental factors. Shrink film is commonly used to package food products, beverages, and pharmaceuticals. There are two main types of shrink films: polyethylene (PE) and polyolefin (PO).

Polyethylene (PE) Shrink Film

PE shrink film is the most widely used type of shrink film due to its low cost and excellent shrink properties. It is commonly used for packaging products such as soft drinks, water bottles, and snack foods. PE shrink film is available in different thicknesses and can be customized with high-quality graphics and printing.

 

Polyolefin (PO) Shrink Film

PO shrink film is a more expensive alternative to PE shrink film. It offers superior clarity and shrink properties, making it ideal for packaging products that require high visibility. PO shrink film is commonly used for packaging products such as cosmetics, electronics, and other high-value products.

Non-Shrink Film

Non-shrink film is a type of polyolefin film that does not shrink when exposed to heat. It is commonly used for packaging products that are sensitive to heat or pressure, such as food products that can be crushed or damaged by the shrink process. There are two main types of non-shrink films: cast and blown.

Cast Film

Cast film is a type of non-shrink polyolefin film that is produced using a flat-die extrusion process. It is commonly used for packaging products such as fresh produce, meat, and cheese. Cast film is available in different thicknesses and can be customized with high-quality graphics and printing.

Blown Film

Blown film is a type of non-shrink polyolefin film that is produced using a blown-film extrusion process. It is commonly used for packaging products such as snack foods, bakery items, and pet foods. Blown film is available in different thicknesses and can be customized with high-quality graphics and printing.

Product Compatibility

One of the most important factors to consider when choosing printed PO film is product compatibility. The film must be compatible with the product being packaged to ensure the safety and quality of the product. Certain products may require specific types of films, such as those that are food grade or that meet specific industry standards.

For example, food products require films that are food grade and safe for consumption. Films that are not food grade can release harmful chemicals and contaminants into the food, affecting its safety and quality. In addition, pharmaceutical products require films that are moisture-resistant and airtight to ensure the product remains safe and effective. It is important to work with a reputable supplier who can provide information about the product compatibility of the printed PO film.
