Shrink film

Shrink wrapping is a simple yet effective process that requires just two elements: the right type of shrink film and heat. With a roll of shrink film and a heating source, products of almost any size can be securely waterproofed, weatherproofed, and tamper-proofed.

Given the flexibility, durability and other valuable advantages of using shrink film, many companies employ this option to package their products.

For retail and shipping applications, three main types of shrink films are commonly used: polyvinyl chloride (PVC), polyolefin, and polyethylene. Each type has unique properties that make it suitable for specific uses. Additionally, these materials can be co-extruded into multilayer films with specialized additives to enhance barrier performance, extend shelf life, or improve appearance. For retail and shipping applications, three main types of shrink films Shrink films can be converted into flattened rollstock, bags, overwrap, banding, and tubing, offering tamper-resistant protection for packaged goods. They are widely used to provide an extra layer of security and stability during storage and transit.

Application methods range from simple to industrial scale. For smaller operations, shrink film can be wrapped around items and sealed with a manual heat blower for a tight, secure fit. For larger packaging needs, heat tunnels or conveyor-based systems are employed for efficiency and consistency.

Among the available options, polyolefin shrink film is the most widely used due to its versatility. It is available in various thicknesses, clarity levels, strengths, and shrink ratios. Other popular materials include PVC, polyethylene, and polypropylene, each offering dependable protection for different industries.
