Tubular shrink wrap refers to any type of plastic that shrinks when exposed to heat, making it ideal for packaging and bundling products. Depending on its application, it comes in various types, each offering unique properties. The shrinkability of this plastic ensures secure and protective packaging.
Types of Tubular Shrink Wrap for Packaging
Shrink Nylon Wrap
This type is usually thicker and is primarily used for bulk packaging. A common example is the six-pack bundles of bottled water.
- PVC Shrink Wrap
PVC shrink wrap is thin and rigid, making it ideal for wrapping food products and consumer goods. It is commonly used for items like sauce bottles or cigarette packs.
- PET Shrink Wrap (Polyethylene Terephthalate – PET)
PET shrink wrap offers higher density, better durability, and a superior shrink ratio of approximately 75-78%. It also provides better printability, making it a premium choice. Due to these enhanced properties, PET shrink wrap is considered the most expensive among tubular shrink wraps.
- POF Shrink Wrap (Polyolefin – POF)
This is a modified version of PVC shrink wrap, offering greater flexibility and a softer texture while maintaining its shrink properties.
Different Forms of Tubular Shrink Wrap
Depending on customer requirements and packaging methods, tubular shrink wrap can be supplied in various formats:
- Single-layer tubular shrink wrap rolls
- Side-open tubular shrink wrap rolls
- Regular tubular shrink wrap
- Pre-cut and sealed shrink wrap (pouch-style shrink wrap)
What Is Tubular Shrink Wrap?
As the name suggests, tubular shrink wrap is produced in a continuous tube-like form, with open ends that allow products to be easily inserted. After insertion, the wrap is cut or sealed using manual or industrial equipment. The final shrink process is completed using a heat gun or a shrink wrapping machine.
Custom Dimensions and Thickness
There are no limitations in manufacturing tubular shrink wrap in any required size or thickness. Customers can request custom dimensions and unique packaging designs tailored to their needs.
