Shrink wrapping products for retail sales can be an efficient choice for a business owner seeking a professional packaging option at affordable prices.
It is use for packaging anything from boats and electrical wire to thousands of different retail and wholesale products.
Shrink film wrap is an effective plastic that can be of four types –
- Polyolefin
- PVC
- Polyethene
- Polypropylene
Mostly manufactrer commonly choice the Shrink wrap packaging, while the other three extensively in multiple industries around the world. Each material used in it is of different characteristics, quality, advantages, and disadvantages where you can know your choice. Once you have chosen the best plastic for your wrapping and packaging project. The widely used shrink wrap is majorly polyolefin. It is widely available in a variety of thicknesses, clarity strengths and shrinks ratios. We use two primary films either appreciated as crosslinked or non-crosslinked). Other shrink films include PVC, polyethene, polypropylene, and several other compositions.
We use mostly PVC shrink wrap because of its lightweight and inexpensive capabilities. PVC is long lasting and Company use for many unique purposes. However, We use it in well-ventilated areas, as it can give off a harmful odour.
Why is it banned?
It develop from harmful products created by decomposition. Bad quality includes – leaves, carbon deposits, and low shrink force. Polyolefin or POF shrink wrap is a prime shrink wrap, as it’s extremely tough and flexible. We can’t question POF quality as these shrink wrap make from 100% recyclable materials, and FDA-approve.
Manufacture
We can make shrink film to shrink in one direction or both directions. These films can be warm when stretched nicely to orient molecules in a well-organised manner. Cooling films are also crucial. This causes it to shrink backwards in its initial position.
Molecules are coiled and twisted having no particular alignment. However, when draw force will be imposed, amorphous regions of the chain will be straightened, and aligned to its direction.
One can visualise the process by stretching the rubber band, and dipping it into liquid nitrogen to freeze in a stretched state. The band will remain in-state as long as it is kept sufficiently cold temperatures. However, when enough heat energy is applied, the rubber band will strike.

The commercial process is the bubble process, sometimes referred to as the tubular process. In this process, the primary tube can be produced by blowing or casting the tube can produce by blowing or casting the tube onto the external or internal mandrel
Water will be helpful in keeping the primary tube cool at the moment . After the primary tube, We have to reheat and inflate to a second bubble using air much like a balloon is blown. The family of shrinks has broadened over the years with many multi-layer constructions being sold today.
Shrink film attributes include shrink, stability, optics, toughness, and slip. About shrink properties, there is onset temp, free shrink, shrink temperature range, memory and overall package appearance.
We use Shrink bands widely to apply over parts of packages for resistance or labels. It can be cousin two packages or parts into multitasking. We widely use in more industrial applications using heavier weight shrink film. Principles remain the same, with the heat shrinking process.
Shrink Wrap Applications –
- Industrial shrink wrap containment of large plant equipment/components.
- Scaffold wrap containment of building/bridges
- Building temporary shrink wrap structures for storage, containers or other business operational uses now see proliferation .
- Marine shrink wrapping of boats or other vehicles.
- Manufacturers prefer the Shrink wrapping now days.
- Disaster counter/relief projects damaged buildings’ roofs.
