How to choose the appropriate thickness of blown PVC shrink film?

Blown PVC shrink film is a material widely used in the packaging industry. It provides beautiful and practical packaging effects for various commodities with its excellent shrinkage, transparency and durability. In practical applications, choosing the appropriate shrink film thickness is crucial, as it directly affects the packaging effect and cost. So, how do we choose the appropriate thickness of blown PVC shrink film?

We need to consider the size and shape of the packaged items. For larger items or items with complex shapes, we need to choose thicker shrink film. Thicker films have stronger support and stability, ensuring that items are less likely to shift or deform during the packaging process. At the same time, thicker film also wraps the item better, giving it a neater, more aesthetic appearance.

We need to consider the aesthetic requirements of the packaging. If we have high requirements for the appearance of the packaging, for example, if we want the packaging surface to be smooth, wrinkle-free, and have clear and sharp edges, then we can choose a thinner shrink film. Thinner films are more likely to develop a uniform texture and appearance during shrinkage, making packaging more attractive.

We also need to consider the durability and tear resistance of the shrink film. For some items that need to withstand large external forces or need to be stored for a long time, we need to choose a shrink film with better durability and tear resistance. This usually means choosing a thicker film, as thicker films have greater strength and toughness and are better able to protect packaged items.

Of course, when choosing the thickness of blown PVC shrink film, we also need to consider cost factors. Membranes of different thicknesses will vary in price, so we need to weigh them based on budget and actual needs. On the premise of meeting packaging needs, choosing a more cost-effective thickness is a reasonable decision.
