How to Choose What is PET Shrink Film? - A Comprehensive Guide.

When it comes to packaging goods, the material you choose makes a huge difference in the overall look and sustainability of your product. One increasingly popular material is PET shrink film, but how do you choose the right one for your needs? In this comprehensive guide, we will go through the various considerations you should make when selecting PET shrink film.

Firstly, it’s important to know what exactly PET shrink film is. PET stands for polyethylene terephthalate, a plastic resin commonly used in plastic products such as water bottles. PET shrink film is a thin plastic film that, when exposed to heat, shrinks inwards to form a tight seal around whatever it is wrapped around. Here are some things to consider when selecting PET shrink film:

1. Thickness: PET shrink film comes in varying thicknesses, typically ranging from 40-80 microns. The thicker the film, the stronger it will be and the more protection your product will have during transport/storage. However, thicker film may also be more difficult to shrink and may require higher temperatures.

2. Shrink percentage: Different products may require different levels of shrinkage, so it’s important to choose a film with the appropriate shrink percentage. This is typically between 45-75%. A higher shrink percentage will result in a tighter seal, but may also increase the risk of the film distorting or tearing.

3. Clarity: PET shrink film can come in a range of different opacities, from completely transparent to opaque. If your product’s branding relies on it being visible through the packaging, a clear film may be the best choice. However, if you have concerns about the product’s appearance (e.g. blemishes or imperfections), an opaque film may be preferable.

4. Custom printing: If you want to print your product’s branding, warnings or other information onto the packaging, PET shrink film can be a great option for custom printing. Look for a supplier that includes this option if this is something you require.

5. Environmental concerns: PET is recyclable, which is a great advantage for eco-friendly businesses. However, it’s important to ensure that your PET shrink film is in fact recyclable and that you are disposing of it in an environmentally responsible manner.

Choosing the right PET shrink film can make all the difference in the appearance and protection of your product. Consider the thickness, shrink percentage, clarity, custom printing options and environmental concerns when making your selection. By doing so, you’ll ensure that your product stands out on the shelf, while also taking care of the planet.
