For items that need to be stored for a long time, what are the requirements for selecting the thickness of shrink film?

For items that need to be stored for a long time, it is crucial to choose the appropriate blown pvc shrink film thickness. Here are some requirements and considerations for shrink film thickness selection for these items:

Considering that items stored for a long time often require better protective properties, it is recommended to choose a relatively thick shrink film. Thicker films generally have higher strength and toughness, can better resist external physical impact and friction, and reduce the risk of packaged items being damaged during storage.

Items stored for a long time are more susceptible to environmental factors, such as the penetration of oxygen and water vapor. Therefore, choosing a shrink film with excellent barrier properties is also key. Thicker films tend to have better barrier properties and can more effectively prevent the entry of harmful substances such as oxygen and water vapor, and protect packaged items from moisture, oxidation and other adverse effects.

The durability and anti-aging properties of the shrink film also need to be considered. Items stored for a long time require the shrink film to maintain good performance stability and not be prone to aging, deformation or cracking. Therefore, when choosing shrink film, you can pay attention to the quality of its material, production process and related durability test data.

While thicker shrink wrap generally provides better protection, there are cost considerations. Choosing a more cost-effective thickness is a reasonable decision given that it meets your protection needs. The performance and price of films of different thicknesses can be comprehensively evaluated to select the most suitable shrink film thickness.
