Basics of Shrink Film
Shrink Properties
Shrink film, a versatile packaging material of a specific gauge, works by contracting tightly to seal around an item when heat is applied. This property ensures products are securely enclosed with stretch film and protected during transport or storage. It’s essential to understand the shrink rate—how much the film contracts—which varies between materials.
Polyolefin films, commonly used for shrink wrapping, offer uniform shrinkage and excellent clarity. Their balanced shrink characteristics make stretch film suitable for a wide range of applications. Heat sealing is the process that initiates the shrinking action. Sealing systems apply precise heat to polyolefin films, causing them to encase items snugly.
Film Selection
Choosing the right type of shrink film is crucial for optimal protection and presentation. The product’s weight, shape, and sensitivity inform this choice. For instance, heavier items may require a thicker gauge polyolefin for added strength and durability.
Film width also plays a pivotal role in packaging efficiency. A properly sized film minimizes waste and ensures seamless application. Selecting a film with appropriate free shrink allows it to conform to irregular shapes without compromising integrity.
Application Process
The application of shrink film involves several steps designed to ensure products are wrapped securely. Initially, an item is enveloped by the film either manually or with automated equipment. Next comes the heat sealing process where edges of the film are sealed to create a loose bag around the product.
After sealing, controlled heat is applied through a tunnel or with a handheld heat gun. This causes the film to contract around the item, providing a tight and transparent layer of protection that conforms precisely to its contours.
Environmental Considerations
In today’s eco-conscious market, selecting films made from low-density polyethylene can be significant as they often have better recyclability profiles than other plastics. Innovations in plastic wrap technology strive towards reducing environmental impact while maintaining packaging performance.
