FAQ

What is shrink in packaging?

Shrink packaging refers to a process of wrapping a product or material in plastic film and then shrinking the film around the product using heat. This creates a tight and secure seal around the product, helping to protect it during shipping and storage.


What is shrink film in food packaging?

Shrink film is commonly used in food packaging to provide a tight and secure seal around perishable food items. The film conforms tightly to the shape of the food, providing protection against moisture, bacteria, and other contaminants. It can also help to extend the shelf life of the food by preventing spoilage or dehydration.


What shrink wrap is used in packaging?

There are several types of shrink wrap that are commonly used in packaging, including polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), and polyolefin (POF). The type of shrink wrap used will depend on factors such as the application, desired properties, and budget. Each type of shrink wrap has its own unique properties and advantages, such as clarity, strength, and resistance to punctures and tears.
