Shrink Wrap vs. Stretch Wrap 

Shrink wrap and stretch wrap are two materials that often come up in the same conversation. They carry similar names, so they must fulfill the same purposes, right? The truth is, these two materials are unique packaging products that are useful in different situations. Today, we'll help you understand the differences between shrink wrap and stretch wrap. 

Some shipments call for extra protection to preserve the product's external features during transit. Shrink wrap is a packing material usually comprising thick polyolefin plastic (although sometimes it comes in LDPE or PVC depending on the application). Unlike its counterpart, shrink wrap is tense, providing little elasticity compared to stretch wrap. As a result of its material and qualities, shrink wrap is one of the most durable packing solutions. 

Shrink Wrap Best Uses and Applications

Shrink wrap is the packing solution for individual items, especially those solely featuring primary packaging. Packers can apply this material by sliding the product between two layers of film and using an L-Bar Sealer machine to cut and seal the shrinkwrap to fit. It then travels through a heat tunnel to shrink the film tight around the product. More automated machinery is available for higher volume applications.

Shrink Wrap Advantages

Shrink wrap is an ideal tool for protecting individual shipments during transit because it comprises a thick plastic material that compresses when exposed to heat. When you ship a product with a shrink wrap seal, you can count on reliable protection against scratches, scuffs, dirt and moisture damage. Improve your packaging method by using shrink wrap for products like calendars, games, books or food that need to arrive to the consumer in perfect condition, without a hint of exterior damage or contamination. 

Stretch wrap helps warehouse and distribution center employees handle day-to-day responsibilities with optimal efficiency. While shrink wrap features thick, stiff polyolefin, stretch wrap comprises thin polyethylene plastic. As a result, stretch wrap delivers the elasticity and cohesive properties crews need to secure pallets from low profile loads to those piled high with boxes. 

Stretch Wrap Best Uses and Applications

Stretch wrap is the perfect solution for warehouses and distribution centers handling high volumes of products in secondary packaging. The material's elasticity enables it to return to its initial state, even when wrapped numerous times around large shipments. Stretch wrap will hold any group of boxes or products together for maximum security during transit. To apply this product, either manually wrap the pallets with hand wrap or use machine wrap on an automated turntable machine.

Stretch Wrap Advantages

Many facilities choose to stock stretch wrap because of its versatility and low price point. Stretch wrap provides a firm hold for shipment, and it also offers reasonable protection against scratches, moisture, dust and other contaminants. What's more, manufacturers produce various types of stretch wrap with different properties, such as UV protection, ventilation, anti-static or branded coloring, for ease of packaging.
