Packaging Wrap FAQs

How do you keep plastic wrap from sticking to itself?

There’s nothing more annoying than plastic wrap folding on itself and getting stuck. With the 40 years of experience that we have here at Magnum Packaging, we have collected some tips and tricks for you to try out to stop your plastic wrap from sticking to itself. 

  1. Store the plastic wrap in a cool place as this will make it easier to handle and stick to surfaces. This can be cold storage space or a warehouse for industrial shrink wrap. 

  2. Wet your fingers before you handle the wrap as this will make the plastic wrap stick to your fingers making it easier to grip and handle. 


Is it safe to wrap food in cling film?

Yes, it is safe to wrap food in cling film. It is advised that you follow the manufacturer’s instructions when applying cling film to food. You should not use cling film on food that you place in the oven as it can melt and contaminate the dish with harmful toxins that should not be ingested. 


Can stretch wrap be recycled?

Yes, stretch wrap can be recycled. It is made with linear low-density polyethylene (LLDPE) which is categorised under category 4 in recycling programmes. 


What is the difference between shrink wrap and stretch wrap? 

The best way to illustrate the difference between shrink wrap and stretch wrap is to point out their notable key points and differences: 

Shrink Wrap

Stretch Wrap

  • Shrink wrap is made from polyolefin plastics and is often used to protect a product from the weather or dust. It can also be used to make multiple boxes/packages together. 

  • Stretch wrap is made from polyethylene plastics and is used to hold products to pallets during transportation. It can also be used to hold together items for storage purposes. 

  • Shrink wrapping can also be breathable meaning that it can reduce any damage that may occur from moisture.

  • Stretch wrapping is cost-effective and is ideal for warehouses or factories that need to use wrapping for the transportation of goods.

  • Shrink wrapping is great for protecting packages from moisture damage as well as from dust and dirt. 

  • Stretch wrap is suitable for a variety of surfaces and there are even UV options to protect packages from sunlight. 


What is the best gauge for shrink wrap? 

It depends on what you are shrink wrapping, but a 60 gauge polyolefin film will work for light food applications. However, if you are transporting items that have sharper edges, we recommend a higher gauge. 

What is shrink wrap used for?

Shrink wrap is a material that is often used to package goods. It can be heated to be applied by a conveyor heat tunnel or by a heat gun. This makes the shrink wrap film shrink tightly around the goods or pallet that is carrying the goods.

Is shrink wrap the same as cling film?

Shrink wrap and cling film share many of the same properties and are often mistaken for one another. Cling film cannot be heated by a heat gun without contaminating or burning whereas shrink wrap is specifically designed to be heated and securely shrink to a smaller size.

Is shrink wrap food safe? 

Shrink wrap is more suited towards securing packaging. There are, however some shrink wraps that can be used to wrap food products that don't migrate or release an odour when they are shrunk with heat. These are usually Polyolefin based but make sure to check with your provider if your shrink wrap is suitable for use with food.
