Three kind of shrink wrap films are mainly used and they are- PVC, PE, and POF shrink film. To know which one is suitable for your purpose, you have to know their differences first.
The plethora of options available for shrink wrap film for packaging of products and for the business, you may get confused and after going to the market you may find the option to be misleading.
Once you know the difference between the POF shrink film, PVC and Polyethylene shrink film and their features and functions, it will be easier to understand for the common people. Be it POF of polyolefin shrink film or PVC or PE, each one of them has a lot of variety in usage but unfortunately, they are mainly used at the retail and food stores for minor works. Each of these films has some distinct capability and characteristic which make these films suitable for some particular application.
Here are the differences between these films:-
- Polyvinyl (PVC) Shrink Film:-One of the most widely used material for shrink packaging in this world is PV shrink film. This is mainly because this material is of extremely lightweight and also it is inexpensive.
The main advantages of PVC are- this material is highly durable, consist of easy shrinking and sealing features and it can be used even on the products which are heat sensitive. In a wide range of industries this material used such as- food industry, construction industry, chemical and pharmaceutical industry, healthcare department and many more. PVC can have direct contact with food and it can also substitute the BOPP overwrap film.
- Polyolefin (POF) Shrink Film:- Polyolefin shrink film or POF is considered as one of the most versatile and durable materials. The polyolefin materials come in with various different features and characteristics. One of these available characteristics is the feature of cross-link because of which it can provide high tensile strength. The measurement of the force which is required for breaking the wrap is known as tensile strength.
Another big advantage of POF is it is transparent. So it becomes easy to see the enclosed item that is wrapped. The associated costs of packaging like the maintenance cost and repair cost can be eliminated with POF as this wrap’s compounds decrease the chances of building up of the material of the sealing component of the entire machinery.
POF is also resistant to the tears and punctures and this material has amazing strength. This is not only advantageous throughout the delivery and supply chain but it makes easier to wrap the irregularly shaped products as well. This item is non-expensive too.
- Polyethylene (PE) Shrink Film:-This is a type of polyofin that means it is a single monomer, formed during the polymerisation with the addition of ethylene. The most common use of this material can be seen during transit. Materials can be individually wrapped or they can be wrapped together- this depends on the nature of the product and the mode of transport being used.
In comparison with the other methods of packaging, these versatile products provide the best combination of protection and per unit cost. This material does not shrink under heat like the other materials; this makes it ideal for transportation. PE is resistant to the punctures and it is extremely durable as well.
The structural integrity is maintained thoroughly as well over time. Alpha Plastomers suggests the use of PE on a vast range of products- from jars and cans to individual product wrapping.
If you know the features, pros, and cons of these materials, you will automatically have an idea about their differences. So according to your purpose and requirement, choose material from these for packaging.
